->''"The movie follows the book, sort of, if you can imagine a cute balloon inflated into a zeppelin."''
-->-- '''Creator/RogerEbert''', review of ''Film/TheCatInTheHat'' (2003)

This is the complete opposite of CompressedAdaptation. It occurs when a short, very simple tale is given a much bigger adaptation, typically as a [[TheMovie feature-length film]]. To be brought up to feature length, the storyline will have to be padded with some new stuff -- a ''lot'' of new stuff. Cue {{Alternative Character Interpretation}}s that require elaborate {{backstor|y}}ies, [[AscendedExtra minor characters given much larger parts]], [[CanonForeigner completely new characters]], and sometimes [[AdaptationInducedPlotHole Plot Holes]], {{Plot Tumor}}s, and a triple dozen subplots that were not in the original work.

This has a tendency to make the story unrecognizable as a retelling of the original. In some instances, the original story will end up as one small part of a much larger, more convoluted story. This will usually be the climax, in which case the film essentially gave you an hour or more of BackStory. This most often happens with movies based on novellas, short stories, video games or children's books. In the children's books instance, this can lead to the introduction of DarkerAndEdgier into a normally benign story or the ''reintroduction'' of elements lost to Disneyfication of classic stories.

While this trope is often associated with the fan complaint "TheyChangedItNowItSucks!", it ''can'' be done well. Remember that TropesAreTools and extensions for adaptations might need to happen to fill the required runtime, just going about it right is the problem most productions face.

Compare ExpandedUniverse. See also AdaptationDecay, AdaptationDistillation, CompressedAdaptation, HumbleBeginnings, PatchworkStory, NotHisSled, UpdatedReRelease. An adaptation InNameOnly goes even further than this, throwing out the original plot and making things up out of whole cloth.


* Live-Action TV
** ''AdaptationExpansion/GameOfThrones''


[[folder:{{Anime}} and Manga]]
* ''Manga/ACertainScientificRailgun'''s anime adaptation includes a lot of material that wasn't in the manga, including an entire new story arc which gave some more satisfying closure to the "Level Upper" arc and foreshadowing several events in the ''Index'' novels.
* As the ''Manga/AttackOnTitan'' anime reaches the end of its first season, there is far more scenes original to the anime (some of which Isayama wanted to put in the manga but cut for pacing reasons). These better develop minor characters, add more action and increase the emotional intensity of various events (for example, Episode 22 is almost entirely original content focusing on the aftermath of the [[spoiler:Special Ops Squad's]] deaths). These scenes have been generally well received.
* Subtly done with ''Manga/AzumangaDaioh'', which expands every joke from the original {{yonkoma}}-style manga. In many cases, [[{{Beat}} the extra length between setup and punchline]] actually makes the joke funnier (a key example: the famous "Osaka with a knife" incident is ''infinitely'' funnier in the anime because of how long passes before you see the weapon.)
* The 1960s ''Manga/{{Batman}}'' manga based all of its stories on comics ''Batman'' stories of the era, but the increase in length from one or two American comics issues to three or four manga chapters meant that they received significant plot complication as well as decompression.
* While ''Anime/BlazBlueAlterMemory'' is largely a [[{{CompressedAdaptation}} Compressed Adaptation]], one episode features Ragna looking after Lambda-11. The episode itself is a modified version of Lambda's gag reel from the second game. Some fans argue that's it one of the (arguably few) ''good'' changes in the anime adaptation, as it develops a relationship between Ragna and Lambda and [[spoiler:Ragna's reaction when Lambda is killed later on in the story is better justified compared to the games]].
* In addition to a great deal of straight-up {{filler}}, the ''Manga/{{Bleach}}'' anime expanded many manga scenes, particularly in flashback sequences. Some of these may have been included to ensure that episodes started and ended at suitable plot points.
** The flashback episode dealing with Ikkaku and Yumichika's history in the Rukongai before they became Shinigami covers how they first met Kenpachi. The expansion of only a couple of canon manga panels into a full episode has caught out some parts of the fandom who don't realise almost the entire episode is {{filler}} and not {{canon}}.
** This is also especially prevalent in the Turn Back the Pendulum Arc, where over half of each of the first two episodes were new material.
** The anime also added an episode to finally give 3rd Espada Tia Harribel a backstory and motivations, something the manga did not do.
** There's also Episode 293, whose second half is the animated rendition of Chapter 392's WhamEpisode [[spoiler: with Hitsugaya almost killing Momo, thinking she was Aizen while under the influence of Kyouka Suigetsu]]. Not only is it [[AnimationBump beautifully animated]], but after the deed is done and the viewer sees the OhCrap expressions on the captains' faces [[MyGodWhatHaveIDone once they realize what truly happened]], there's an extra scene where [[spoiler:Hitsugaya, having withdrawn his sword from Momo's body, gently [[PietaPlagiarism carries her in his arms]] to a nearby terrace, which is when she asks him why he hurt her before passing out. ''Then'' he screams and attacks Aizen in a blind fury.]] For all the faults the anime has, this was ''really'' well-done.
** The last episode of the anime add scenes to wrap up the end of the Full Bringers arc, particularly [[spoiler: a talk between Ichigo, Renji and Rukia after Ichigo goes retrieve Ginjo's corpse (Rukia didn't show up, only Renji)]] and a whole epilogue that shows both the Shinigami going with their lives ([[spoiler: i.e, it shows that Momo and Hitsugaya ultimately recovered from the horrible incident described above]]) and Ichigo happily returning home to his family and friends ([[spoiler: this includes Yuzu, his little sister who still can't see spirits -- her spiritually aware twin Karin points out where Ichigo's coming from so she can wave hello to him.]])
* The manga adaptation of ''VideoGame/BreathOfFireIV'' in Comic Blade Avarus manages to be simultaneously an example of this trope ''and'' AdaptationDistillation. The manga is a distillation of a 40+ hour [=JRPG=] with MultipleEndings, Multiple Plots, and which has been legitimately described in parts as FetchQuest Hell; however, the manga also added a fair amount of material from the official artbook that was never included in the game.
* ''Anime/BrigadoonMarinAndMelan'' had only two manga volumes, while the anime went well over 20 episodes and introduced several new characters.
* The ''Manga/CardcaptorSakura'' manga had nineteen cards, the anime had 52 -- which is appropriately serialized for a 52-episode anime setup (and even then, the anime got ''70'' episodes plus two movies). There were also new plot threads and the addition of Meilin.
* ''Manga/DeathNote'' is actually an expansion of the original ''Death Note'' story, which was a one-shot chapter. It featured a junior high student who finds the titular notebook which was accidentally dropped by Ryuk, but since he can't read English well, he uses it as a diary and ends up killing people. [[spoiler: Ryuk eventually finds him and gives him the Death Eraser, which allows him to bring the people whose names he had written into the notebook back to life.]] The much more well-known manga is an expansion on the idea, turning the junior high student into a high school student with a [[AGodAmI god complex]] and the FilmNoir detective a mega genius with an extreme sweet tooth. And lots and lots of IKnowYouKnowIKnow.
** Also, in the manga, Matt, while still a very minor character, had a bigger role than he did in the anime.
* In some ''Manga/DetectiveConan'' cases adapted from manga to anime, the anime adds all kinds of details to the basic layouts already given, and sometimes these work ''really'' well. A great example is the resolution of the [[spoiler: Detectives Koshien]] case: the manga makes TheReveal that [[spoiler: Koshimizu killed Tokitsu to punish him for driving her best friend Kana to suicide, upon wrongfully getting her accused of killing her boss (who actually commited suicide)]] rather straightforward and short, but the anime expands this via adding [[spoiler: flashbacks of Kana crossing the DespairEventHorizon due to the false accusation ''and'' of her throwing herself off a cliff (one of them [[StartsWithASuicide almost at the start of the special]]), alongside another that shows [[TheOphelia the boss herself]] falling in madness]], and concluding with [[spoiler: Koshimizu [[CryCute crying as she explains her reasons]].]]
** The animated special ''Episode One'' expands on the first two episodes of the series, adding LOTS of anime-original material (and those were episodes that ''already'' added scenes to the original manga's rendition): a cameo of [[spoiler: Sherry/Shiho/Ai finding out that the fatal drug can be a FountainOfYouth]] a scene where [[ActionGirl Hina Wada]] apprehends a thief on her own, several scenes [[ShipTease with Ran and Shinichi interacting on their own]], another where the culprit of the first case is seen visiting Sonoko's parents and panicking when Shinichi shows up, [[spoiler: Gin and Vodka disposing of an apparent traitor]], the karate tournament that Ran wins and leads to Shinichi taking her to Tropical Land to celebrate ''and'' showcases the time when Makoto fell in LoveAtFirstSight with Sonoko, [[spoiler: Shinichi's parents in disguises]], tiny apparitions of [[spoiler: Kir (as Rena Mizuhashi), Korn and Chianti]], a change in how the Detective Boys first appeared, [[spoiler: more details about Gin and Vodka's blackmail operation that led to Shinichi being shrunk into Conan]], etc. The very final sequence also includes ''quite'' a change: [[spoiler: it showcases Akemi Miyano's death... but following the manga rendition, as her first and last intervention had been changed in the anime to make her survive for some time: here, such a modification is probably retconned.]]
* ''Franchise/DragonBall''
** ''Manga/DragonBall'' does this with a few episodes. A notable example; in the manga, there's a scene where a female Red Ribbon officer [[TheSmurfettePrinciple (and apparently the only one in the whole army)]] known as Colonel Violet presents Commander Red with a Dragon Ball. In the anime adaptation of that episode, not only does the audience see Violet retrieve it, but later, upon realizing that Goku's attack is going to spell the end of the Army, [[ScrewThisImOuttaHere she loots Red's riches and gets out of Dodge]].
** The search for the six-star Dragon Ball in the Red Ribbon Army Saga is also expanded greatly. In the manga, Goku swoops in, beats up two {{mooks}}, beats up Colonel Silver, and leaves with the Dragon Ball. In the anime, this storyline is expanded to include [[GoldfishPoopGang the Pilaf Gang]], Chi-Chi, the Ox King, and a shifty antique shop owner.
** ''Anime/DragonBallZ'': Gohan's training in preparation for the fight with the Saiyans. In the manga, all we see is Gohan going off after discovering the new clothes Piccolo gave him while he was sleeping, and then in the next chapter they skip ahead six months to his training with Piccolo. However, in the anime, a good amount of Gohan's adventures on the island Piccolo left him on for those six months are shown, plus [[CharacterDevelopment he's seen gradually developing from a sheltered and scared little kid to a gentle, yet confident and self-sufficient fighter]].
** As well as giving some actual screentime to Tenshinhan, Yamcha, and Chaotzu before the Nappa fight. The latter three heroes also got a well-deserved moment of awesome when they thrashed the Ginyu Force as part of the training they received from Kaio-sama.
** Another ''DBZ'' example involving Gohan was the Great Saiyaman arc, in which Gohan adopts a (very silly) superhero persona. In the manga this is treated almost as a one-off joke and Videl deduces Saiyaman's identity in approximately two minutes. In the anime, more of Saiyaman's exploits are shown, as well as how Gohan tries to balance his school life and superhero roles, and Videl is shown gradually catching on to all this over the course of several episodes.
* The ''Manga/FairyTail'' anime, in addition to giving the supporting cast a bit more attention, will add in little bits of foreshadowing that normally didn't appear in the manga until anywhere twenty to a hundred chapters later, making the story seem a lot more planned. Thus far they've included Laxus' hand sign in one of the very first episodes, turning it into a guild gesture; an early display of Levy's ability to deactivate any form of written spell; a glimpse of the Oración Seis members as child slaves in the Tower of Heaven ''and a cause for their desires''; and the mention that Siegrain and Jellal are twins right of the bat rather than wait until the arc was almost over like Mashima did; and a mildly exasperated sigh from Cana upon hearing Gildarts' name mentioned, ''very'' subtly alluding to [[spoiler:[[WellDoneSonGuy her daddy issues with him]]]].
** Story arcs after the first season take an even further step. The Nirvana arc sees the return of Erigor, a minor villain who [[WhatHappenedToTheMouse disappeared from the manga without a trace, even after Lucy speculated he would come back to take revenge,]] which he does in the anime... But his fight with Natsu doesn't even last five minutes. In fact, he's made the one who [[spoiler: Jellal steals his clothes from after reviving]], a role given to a nameless {{mook}} in the manga. The Edolas arc gives attention to off-screen events only mentioned in the manga, such as Gajeel's adventure in Edolas that leads to Gray and Erza's rescue, teaming up with his [[CanonForeigner anime-exclusive counterpart]] to do it, and the Edolas version of Fairy Tail's debate over whether or not to stand up against the army after years of running away from them. After the arc ends, they even dedicate half an episode showing [[spoiler: Mystogan ruling Edolas as king and giving the villains their proper punishments while the rest of the world adapts to life without magic. It even gives us the suggestion that the main villain of the arc, Faust, was Makarov's counterpart all along.]] The Tenrou Island arc fleshes out Ultear's backstory where she is apparently abandoned by her mother and experimented on at the research facility, which turns out to be run by Brain, the villain of the Nirvana arc. And while Natsu and Co. are duking it out with Hades, we actually get to see what the rest of the guild is doing as they're holding the fort for their injured (according to the anime, that is fending off already defeated minor villains who are still hanging around the island).
** The Key of the Starry Sky arc in the anime is pretty much considered canon -- the manga even gives it a passing mention. It gives Earthland versions of the Royal Military characters met in Edolas, [[spoiler: time skip looks of returning Oracion Seis members,]] we learn that Dranbalt was DrowningHisSorrows since the previous arc, and Kinana has some needed development concerning her past (which was only mentioned in her profile in the manga).
* When ''VideoGame/FireEmblemGenealogyOfTheHolyWar'' was adapted into a manga by seinen author Mitsuki Oosawa, she decided to add more content and plot development. As a result, this adaptation covers a lot of characterization of the side characters and goes into more detail on what happens within the countries where the battles happen. For instance, it creates a rather big subplot on the... [[BrotherSisterIncest unique situation]] between Eldigan and Raquesis... Though [[DerailingLoveInterests at the cost of making Eldigan's wife a jealous bitch]] and omitting Raquesis's suitor [[PunchClockHero Beowulf]] [[spoiler: so she can have [[KnightInShiningArmor Finn]] as her SecondLove.]] The LoveTriangle between [[BlowYouAway Lewyn,]] [[LadyOfWar Ferry,]] and [[GenkiGirl Sylvia]] develops relatively smoothly, and the losing girl [[spoiler:(Sylvia)]] is given a far more sympathetic role; and it delves rather well in the psyche of the future MagnificentBastard and BigBad, [[spoiler: Arvis of Velthomer,]] making him a JerkassWoobie.
* For all the omissions and changes they made, the ''[[Manga/FistOfTheNorthStar Fist of the North Star: Legends of the True Savior]]'' [[TheMovie movies]] and {{OVA}}s feature plenty of new story elements as well. The first four installments did so by retelling events from the manga from the perspective of characters other than Kenshiro, while the fifth movie was actually a {{prequel}} to the manga.
** The 1984 TV series, although it toned down some of the violence and had [[OvertookTheManga lots of filler]], also actually [[CharacterDevelopment develops many characters beyond what they were developed in the manga]]. Shin, in particular, is given a much more prominent role and exploration of his backstory and motivations, [[AntiVillain making him a much more sympathetic character]]. They also add in a lot of variations of the Nanto schools, many interesting min-bosses and civilians (including several ''Badass Bystanders''), new towns (and even naming random locations visited in the manga), and show more of the daily lifestyles and cultures that emerged after the nuclear war.
* With one exception, Creator/JunjiIto's manga adaptation of ''Literature/{{Frankenstein}}'' is this. The added scenes detailed Frankenstein having nightmares of Justine, as well as Henry Clerval discovering Frankenstein creating the female wretch, helping him, and then the wretch coming in with a head for the female. [[spoiler: Which is Justine's head.]] An additional theme added to the adaptation is [[spoiler: Clerval telling Frankenstein this could resurrect the dead... however she CameBackWrong and tried to kill the wretch, is then killed in self-defense.]] From then on, it veers back on track with the novel we know of.
* ''Manga/FullmetalAlchemist'':
** The [[Anime/FullmetalAlchemist 2003 anime version]] deviated from the manga on many points due to a huge case of OvertookTheManga (which was finished ''in 2012''), but even the ones where it stayed the same had additional scenes. The Liore arc, one of the more faithfully adapted ones, has several added scenes expanding on Rose's backstory, and shows Father Cornello and his minions giving the Elric brothers more trouble than they did in the manga. Some minor plots are expanded upon, as in the anime, Ed has a TenMinuteRetirement after [[spoiler:Nina's death]], during which he and Winry are captured by Barry the Chopper (whom the brothers don't meet in the manga until his soul is bound to a suit of armor) and Ed has to fight him to free himself and Winry and then help arrest him.
** The ''Brotherhood'' anime was more faithful to the manga itself (they finished at the same time!), but it also had some scenes and episodes dedicated to this trope. i.e. the first episode was full-on anime-only material, centered on a CanonForeigner named Isaac "Freezing Alchemist" [=McDougal=]... who turns out to be [[spoiler: the first person to ever realize Father's plans to turn Amestris into a giant transmutation circle, which [[HeKnowsTooMuch gets him killed by Wrath]] on-screen (just like the second person, Hughes, was killed by Envy some time later). Twenty episodes later, when Ed ''also'' deduces the truth [[OhCrap and is horrified at it]], his train of thoughts include a flashback to [=McDougal=]'s words during their fight, which turns from ForeShadowing to {{wham line}}s.]]
* ''LightNovel/FullMetalPanic: The Second Raid'' does this, adapting two short novels into 13 episodes. The first four episodes take place before the novels even start, and add a considerable amount of background to the story. This mostly makes things better, by increasing the personal involvement of the characters in the plot. There's also the addition of entirely new characters, specifically, the fact that two forgettable male henchmen of the villain were [[GenderFlip replaced with]] beautiful twin sisters who play a fairly major role as rivals to the protagonists. Their first appearance was nude, together in the shower, then gradually getting dressed while being [[{{Twincest}} way too intimate]]. Because [[Creator/KyotoAnimation KyoAni]].
* In the original ''Manga/FushigiYuugi'' manga, when [[spoiler: Suzuno and Tatara die, they simply die. The anime expands on this scene to have Tatara's soul come to Suzuno after he dies and as ''she'' dies of old age, so they're TogetherInDeath]]. The added scene went over so well that Creator/YuuWatase has said she loves that detail and regrets not having thought of doing it in the manga.
* Gainax anime are prone to manga expansions due to their limited 26-episode average span budgets:
** ''Anime/{{FLCL}}'' got a slight expansion that was cleverly added, but a little unsettling concerning when Naota attacked his father.
** ''Anime/TengenToppaGurrenLagann'' had additional backstory about The Black Siblings tossed in, while at the same time having them introduced at the point where Viral made his debut, while also detailing how Dayakka fell in love with Kiyoh, and, unfortunately, [[spoiler: the tearful reactions of Kittan's sisters when they learned of his HeroicSacrifice.]] The manga also has a scene that shows Yoko's boobs in full view during a shower scene. Only one problem--it's the shower she took after [[spoiler:Kamina died, and she's crying her eyes out.]]
** The ''Anime/NeonGenesisEvangelion'' manga fleshes out a number of characters. Among other things, the manga explores Asuka's family situation in greater detail, provides a TroubledBackstoryFlashback for Kaji, and gives a much larger role to [[AscendedExtra Kaworu]].
*** The final chapter [[spoiler: picks up after the events of ''End of Evangelion'', showing Shinji and Asuka's civilian existences after Human Instrumentality is averted]].
** Kaworu's storyline is similarly expanded in the ''Anime/RebuildOfEvangelion'' films, despite the fact that he only ever appeared in one episode of the original TV show.
* The [[RecursiveAdaptation manga adaptation]] of ''Anime/GhostInTheShellStandAloneComplex'' would usually adapt episodes from the TV series, but with the plots expanded to fit the length of [[WritingForTheTrade a standard manga story arc]]. For instance, the adaptation of "¥€$," explored Fem's backstory and motivations in far greater detail, and significantly lengthened her fight with the Major.
* ''LightNovel/HaruhiSuzumiya'':
** The original LightNovel story of "Endless Eight" was a short story that tells the story of a GroundhogDayLoop and its resolution, as seen through the 15,498th and final iteration through the loop. The anime, on the other hand has aired eight episodes of this, which depict: (a) an unnumbered iteration where the protagonists don't realize they're in a time loop; (b) six nearly identical subsequent iterations with only cosmetic differences where the SOS brigade discover the loop but, contrary to the short story, ''don't'' manage to solve it; and (c) a final episode--iteration number 15,532--where Kyon finally manages to sever the loop and end the 595 years of repetition upon repetition.
** The movie, ''The Disappearance of Haruhi Suzumiya'' also counts, since it expands a rather short novel into a massive, nearly-three-hours-long feature film.
* The first six episodes of ''Anime/{{Hellsing}}'' have significantly more character development and material than the two volumes of the manga they are based on.
* The ''Manga/HidamariSketch'' {{yonkoma}} started at around the same time (early 2004) as ''Anime/LuckyStar'' and both were first animated at roughly the same time (early 2007). Yet, ''Hidamari Sketch'' has a much slower pace. It is only through Creator/StudioShaft's expansion (with the insertion of original stories) that it can sustain the 42 episodes it has or will air. Major expansion points: [[AscendedExtra Chika was ascended from a referenced unnamed character to arguably one of the major characters]]. The anime played up the manga's relatively normal RomanticTwoGirlFriendship content, to the level that Hiro and Sae can be said as platonically married in the anime. Natsume's {{tsundere}} tendencies are magnified in the anime.
* In the ''VisualNovel/HigurashiWhenTheyCry'' manga. Some scenes expand on their sound novel counterparts and new scenes are added, in contrast to the anime's CompressedAdaptation.
** The ending of Tsumihoroboshi-hen in the anime makes more sense. And it devotes an episode to it. But they do end up screwing the beginning to the associated next arc.
* The original ''Manga/InuYasha'' series could be prone to this. One notable example is the defeat of [[EvilWeapon Toukijin]] whose creation was commissioned by Sesshoumaru from the fangs of a powerful youkai that had hated Inuyasha. The sword [[DemonicPossession takes over]] its creator Kaijinbou as soon as its made and hunts down Inuyasha whom it hates. Kaijinbou, unable to cope with his own creation's sheer power, explodes and the sword lands in the ground. Not even [[UltimateBlacksmith Toutousai]] can approach the sword, so powerful is its evil aura. In the manga, Sesshoumaru immediately arrives and [[MuggingTheMonster defeats]] and [[MasterSwordsman masters]] Toukijin the second he touches it. In the anime, Adaptation Expansion has the sword begin the corrupt its surrounding area as soon as it lands in the shrine and, since no-one can approach it, Miroku begins to organize the construction of a shrine to try and [[SealedEvilInACan contain]] the evil. Only after this Adaptation Expansion does Sesshoumaru finally arrive to defeat and master the sword.
* The ''Franchise/JoJosBizarreAdventure'' anime was made well into the Manga's run, and as such it can add and alter scenes to better fit the direction of the story on account of it being available in its entirety.
** When the anime has time to slow down the pace, it fleshes out various scenes which were only briefly mentioned or resolved quickly in the manga, such as Caesar's battle with Wamuu, Lisa Lisa's backstory, and the entire ''Battle Tendency'' epilogue. Stardust Crusaders has included some of this as well, such as Polnareff being interrogated by police after the battle with Devo, and Jotaro getting a replica of his uniform jacket and Anne getting on the plane back home after the Wheel of Fortune fight (both of which happened off-panel in the manga with a off-handed mention).
** To a lesser extent, the anime also smooths over Araki's tendency to bring out major developments with little foreshadowing. Jotaro's future career in marine biology is hinted at when he's shown reading books on it in an anime only scene. Most notably, the BirthmarkOfDestiny in the manga was brought up only in Part 3 as a hasty retcon to show how all of the Joestars are related, while the anime draws it onto the protagonists of the early Parts, to show that it was there all along. Even Josuke was given a small scene showing his mark in an episode that more strongly tied him into the family.
* ''Manga/KamenRiderSpirits'' is essentially an alternate retelling of [[Film/KamenRiderZX a 45-minute TV special]]. It started in 2001, and is still running (though currently on hiatus). Mostly this is because ZX's origin special was focused solely on Murasame[=/=]ZX's battle with Badan; ''Spirits'' shows what the other nine Showa Kamen Riders were doing after their series, as well as [[CanonWelding tying everything together]] by having the remnants of their old enemies joining forces with Badan.
* ''Manga/KiniroMosaic'' has a similar case to ''Kotoura-san'' above, in which the backstory of Shinobu's homestay at the Carteret--which also took the first 10 minutes of the anime--was expanded from ''exactly one strip'', when Shinobu recalled at the time, the only English she knew was "Hello" and the only Japanese Alice knew was "Arigato."
* The ''Kodomo no Jikan'' anime often expands conversations, moves things around occasionally and changes some character development.
* The ''Manga/KOn'' anime is well over half new material, which was a given, with it being based on a 4-panel manga.
* The anime adaptation of ''Manga/KotouraSan'', out of necessity--not only the original was a {{yonkoma}}, but that the animators switched the story's perspective from that of Manabe to that of Haruka. Net result: the DownerBeginning that portrays Haruka's {{backstory}}--and the thing that made the series a bit of a SleeperHit--can be said to be expanded from the two or three strips where Haruka told Manabe her case of BlessedWithSuck.
* The episodes 8 and 10 of the anime ''Manga/LoveHina'', which likewise improve upon the manga chapters.
* ''Manga/LuckyStar'' had a lot of new material added into the anime. ''For example'', ''all'' of the ''LightNovel/HaruhiSuzumiya'' references.
** Also, anybody who watched the first episode remembers, for better or for worse, the food discussion that took up roughly half the episode. The manga's version of the discussion? Four strips, focusing on the choco-cornet.
* The anime adaptation of ''Manga/MagicKnightRayearth'' slows the pacing of both halves and uses much of the time to show the girls' travel in more detail, allowing them to meet some of the ordinary people of Cephiro and learn more about the invading countries in Rayearth II. The game adaptation takes it further by adding multiple towns and new characters who the girls help or learn skills from.
* ''Manga/{{MAR}}'': The manga ending was very rushed bordering on anti-climatic. The anime however, not only expands on the ending but give a completely different final battle with most of the heroes killed (though brought back later) and one of them [[spoiler:Snow]] merging with her real world counterpart [[spoiler:Koyuki]] to be with Ginta when he goes back.
* The anime adaptation of ''[[Manga/FutureDiary Mirai Nikki]]'' gives us some background for Marco and Ai, the BattleCouple that make up Seventh, something that wasn't included in the manga. [[spoiler: Ai was abandoned by her parents, then taken in by Eighth, and grew very attached to Marco. When Marco tried encouraging her to stop being so clingy, Ai fell prey to a trap concocted by some AlphaBitch students, and was gangraped as a result; Marco killed the rapists, and swore to protect Ai from then on.]]
* An unusual example of this trope is ''Anime/MobileSuitGundam'' when it is adapted into the manga ''Manga/MobileSuitGundamTheOrigin''. Being a 43-episode TV series, there's no shortage of source material, but the author, Yoshikazu Yasuhiko, did more than that -- he streamlined the original storyline while visiting many background events and character histories. This included [[WorthyOpponent Char]] [[AcePilot Aznable]] and [[TheChick Sayla]] [[ActionGirl Mass's]] childhood and exile, Char's subsequent enrollment in [[TheEmpire Zeon's]] military, the path to the One Year War (up to the Battle of Loum, where TheFederation's space fleet suffered a devastating defeat) and [[ReasonableAuthorityFigure General Revil's]] capture and escape. Yasuhiko's adaptation is quite popular in Japan and this expansion is praised by fans, and the manga is still ongoing.
** There is also an adaptation of ''Anime/MobileSuitGundamSEED'', ''Mobile Suit Gundam SEED: Re'', which not only expands characterizations and events, but also advances Mobile Suits with new weaponry, some of which hint at other suits. For instance, the Blitz Gundam is given gear that is later seen on the Testament Gundam and the Astray Gold Frame Amatsu, suits from ''Manga/MobileSuitGundamSEEDAstray''.
** A number of manga and sidestories in the GundamExpandedUniverse likewise expand on various series and characters. Whether it be ''Origin'' style updates like ''Anime/MobileSuitGundam0083StardustMemory: Rebellion'' or ''Manga/MobileSuitZetaGundamDayAfterTomorrow - From Kai Shiden's Report.''
* ''Manga/{{Naruto}}'':
** Episode 133 of stretches out almost everything from the manga chapter it was based on, and the adds a whole bunch of things that were never there in the first place, to the point where it's about fifty percent {{filler}}.
** The anime frequently does this when it wants to add time by ways other than plain old {{filler}}. For example, Temari and Tenten's fight ([[CurbstompBattle if you can call it that]]) was off-screen in the manga, but on-screen in the anime. ''Shippuden'' has a filler arc that actually gives one character (Asuma) some backstory (although the anime already did that with pre-TimeSkip filler to Kurenai, Anko, and Ibiki) and another detailing [[spoiler:the capture and sealing of one of the third tailed beast, Isobu]] when in the manga this we only saw half a chapter of this and most of it took place offscreen (which is a good thing, as many were disappointed that we didn't get to see any of this in the manga.)
*** Likewise, a filler arc in the anime actually details a character named Utakata who is actually the [[spoiler:Jinchuriki of Saiken, the six-tailed slug.]] Utakata actually ''does'' appear in the manga, but [[spoiler:was captured off-screen and along with the other Jinchuriki sans Gaara, Killer Bee, and Naruto, was absent for about a year until he was resurrected along with all the other Jinchuriki who were captured by Akatsuki.]] As a result, we get to know who Utakata is -- and unfortunately, see just how dismal his fate is...
** Episodes 1 and 3 feature EarlyBirdCameo[=s=] by the future members of Team 8 and 10, who don't appear in the manga until the start of the Chuunin Exam arc, possibly to acknowledge their existence as part of Naruto's class.
** How about the infamous [[TheUnreveal 'Unmask Kakashi']] episode? It was just a 3-page manga-special, yet they expanded the story with a much better ending... Which gave birth to the [[BizarroEpisode screwiest episode]] of the original series. [[spoiler: and much later, to a retelling from Kakashi's POV.... where at the end, Kakashi's face '''is actually seen onscreen'''.]]
** In the manga, Kakashi and Might Guy had an [[OffscreenMomentOfAwesome alluded battle]] against [[spoiler:Jinpachi and Kushimaru of the Hidden Mist]]. Now, given the nature of manga writing, some things are bound to get cut out, but this one was a tad too egregious to pass up for fans. The anime, perceptive to their base, adapted this battle into a full episode, making up for the plot element Kishimoto decided was unimportant at the time. Give those folks a medal for their kindness.
** Episodes 166 and 167 have the most Adaptation Expansion in the entire series. Instead of trying to defeat Pain herself, Hinata decides to distract him in order to free Naruto from the spikes binding him to the ground. She didn't get beat down once, she got beat down ''multiple times'' but being a PluckyGirl, she got back to her feet each one. She then tried one last time to remove the spike from Naruto's hands, but Pain does the last attack. Then along came 167, with Naruto doing some fighting in the 4-tailed mode (it only lasted for one panel in the manga,) then unleashing hell on Pain in the 6-tailed mode with a series of attacks, including [[BeamSpam a rapid-fire mini-Tailed Beast Bomb attack]] and a [[FrickinLaserBeams Tailed Beast Laser]] (both attacks were [[CanonImmigrant actually imported]] much later in the manga;) then Naruto goes 8-tailed and creates a ''meteor shower'' with a stream of flames igniting the debris flying out of the Chibaku Tensei. To say the animation in both episodes is [[OffModel odd]] is an understatement; nonetheless, the fluid, fast-paced animation made for action-packed episodes.
** The village's celebration of Naruto's victory over Pain is also greatly extended, complete with added scenes of characters like Ebisu and Iruka proudly reflecting on how Naruto went from being a pariah to one of the most celebrated heroes in Konohagakure's history.
** When the anime was in danger of the dreaded [[OvertookTheManga manga overlap]], it went on a massive flashback tangent bigger than any other form of {{padding}} that had been done before. It started at a point in the manga that presented several major flashbacks in a row. This span of flashbacks did not stick for very long in the manga and focused primarily on [[spoiler:Obito's]] past and how Kakashi accidentally became an UnwittingInstigatorOfDoom. The animation studio, however, decided to keep rolling with the flashbacks and turned the short cutaway into one uninterrupted run of throwback history until they milked it as far as they could. Though it was not by any means boring, it effectively shelved an arc about ''all-out war'' to showcase '''''another''''' ''all-out-war''. On the plus side, it depicts the formation of Akatsuki on a deeper level, shows that Tobi and Danzou played a bigger part in the tragedy which befell Nagato and Hanzou, revealed Kakashi's ANBU days, something fans have long desired, and even spotlights Yamato's backstory, including the origin of his second codename, Tenzou. All because [[spoiler:Obito]] revealed how he had survived his brush with death. ''Holy freaking crap''.
** Similarly done with another filler arc after [[spoiler:Naruto's death]]. Tsunade puts her faith in Sakura assisting Naruto, remembering the Chuunin exams that took place during the TimeSkip. Not only does this flashback arc detail Sakura's plight of the exams, it also deals with the fate of the other entrance, notably including Choumei's jinchuuriki Fuu, and it also shows Jiraiya's attempts at getting Naruto to control the Kyuubi that culminated in Naruto going 4-tails and nearly-killing him.
** One of the most welcome changes to the anime over the manga is the ''Mizuki Strikes Back'' arc for the amount of screen time that it bestows upon fan favourite Iruka as well as making Naruto's first ever on-screen enemy Mizuki ''far'' more badass than he ever was originally.
** In yet another major example, episode 460 marks the beginning of one of the few short filler arcs to not only be accepted, but outright regarded as necessary: [[spoiler: giving the formerly [[GenericDoomsdayVillain generic]] and [[GiantSpaceFleaFromNowhere unexplained]] [[BigBad Kaguya Otsutsuki]] some much-needed attention in the form of a greatly-expanded backstory and personality. Whether it worked or not, it's in the eye of the beholder.]]
** Sasuke's and Naruto's final fight, like the one before, got a massive revamp in the anime. Highlights include a pre- SuperMode brawl (when the manga had them use their powers from the get-go), the return of Kirin, and a power-boost of Sasuke's [[spoiler:Tailed Beast]] Susanoo (The manga had them on roughly equal grounds, with Sasuke having a slight upper hand, but the anime had Sasuke ''completely overpower'' Naruto, to the point where an additional clone was inserted ''just to be [[ImpaledWithExtremePrejudice brutally murdered with ease]].'')
* As a result of having relatively few opportunities to put in filler arcs in later anime episodes, later ''Manga/OnePiece'' episodes cover exactly a chapter worth of material to avoid [[OvertookTheManga getting closer to where the manga is]]. As most chapters don't have 20 minutes worth of material, a good portion of the episodes ends up being filler, primarily expanding on scenes, giving what is happening in a single panel more time on-screen and showing what a character who had not been shown in the actual manga chapter is doing (for example, Brook looking for milk before going back to fight Oars in the Thriller Bark Arc).
* ''Anime/Persona4TheAnimation'' has several. [[VideoGame/{{Persona 4}} The game]] doesn't show the start of Chie and Yukiko's friendship, but the anime does. We get Yu's (the protagonist) personality because he makes his own choices rather than [[HeroicMime going with ours]]. We also get to hear one of [[IdolSinger Rise's songs]].
* ''Anime/Persona5TheDayBreakers'' is a one-episode OVA that expands upon one of the [[VideoGame/Persona5 original game]]'s side-missions.
* The ''Anime/{{Pokemon}}'' anime is a shining example, having perhaps a whole two-thirds of the episodes being content added into the world provided by the games. In fact, they did a 36-episode ''story arc'' based outside of the established worlds (The Orange Islands -- the ''second'' season, no less!)
** While ''Manga/PokemonSpecial'' stays true to the games for the most part, new characterizations and plots do get added on.
* The original ''Manga/SailorMoon'' anime expands 12- and 13-chapter manga arcs into entire seasons of 40+ episodes. Enemy generals ''really'' benefit from it, seeing their tenure extend over several MonsterOfTheWeek episodes and fleshing them out. (For example, the Four Phantom Sisters and the Amazon Trio were [[MonsterOfTheWeek MOTWs]] ''themselves.'' Instead, we get some of the best characters in the franchise out of them. Also, Jadeite was introduced in act one, commanded from behind the scenes in act two, and acted as the villain of the week and got reduced to a skeleton by one blast from the newly-minted Sailor Mars in act three. Animated Jadeite gets ''thirteen'' episodes and is a real threat.)
** ''Series/PrettyGuardianSailorMoon'' pretty much changed a lot of things and still was able to expand on the original story.
** ''Anime/SailorMoonCrystal'' attempts to expand the roles of the Four Heavenly Kings in its first story arc, keeping them alive past the points of their canon deaths in order to introduce a plot point regarding their romantic involvement with the Sailor Guardians in their past lives. Since ''Crystal'' is a TruerToTheText adaptation which otherwise follows the manga scene for scene, this subplot doesn't go much of anywhere before they are unceremoniously killed off in the buildup to the finale.
* ''Manga/{{Saiyuki}}'' has a lot of built-up bits in the anime (the first series filler being a lot less random than the second and third, the filler tends to focus on backstories of the characters being dragged up in some way). Homura (and his arc) was created for the first anime (by the original author though). He does however feature briefly in the manga but his main story is told in the anime. Hazel was originally the same but Minekura decided she wanted to do her own arc about him (which is why the anime and manga are very different; the anime writers interpreted her directions differently).
* The ''Manga/SchoolLive'' anime has two main differences from the manga right off the bat. The first is Miki, a character who joins the cast later, is present at the beginning. More in line with this trope is Taroumaru, a puppy that serves as the TeamPet in the anime, but in the manga wa a OneShotCharacter who appeared in a flashback as a puppy Yuki recovered only ''after'' [[spoiler:it had [[RaisingTheSteaks been bitten by a zombie]]]].
* Inverted with ''LightNovel/{{Slayers}}'' and its original source of canon, the LightNovel series. The regular series is fifteen books long, and the first half is the basis for one manga series and two seasons of the anime. The ''Slayers Special''/''Smash'' novels take place before the original series. While four movies and six [=OVAs=] cover a good amount of Lina's prequel time, there are ''over thirty'' novels. As of this writing, ''Smash'' is on hiatus, but definitely not cancelled, so it won't end anytime soon. This creates some serious FridgeLogic when it's revealed that the ''Special/Smash'' series takes place over the span of two years, while the regular series spans roughly four.
** The manga adaptation of the ''Slayers Premium'' NonSerialMovie clarifies a few loose plot points and makes Amelia, Zelgadis, and Xellos more active in the events that go on, whereas in the movie, they (especially Xellos) were moving scenery.
* The anime of ''Manga/SoulEaterNot'' adds new scenes and events that never happened in the manga, and while it still keeps the more important events, it is much differently paced. This has somewhat help to expand on the personalities and the interactions of the characters, and it even allows more of the original ''Anime/SoulEater'' cast to have cameos more often.
* The Anime version of ''Series/{{Supernatural}}'' gives us more background on Meg and some of the Special Children. Lily and Jake get [[ADayInTheLimelight an episode of their own each]] ("Darkness Calling" and "Loser", respectively) in [[Anime/{{Supernatural}} Supernatural: The Animation]].
* In the ''Manga/{{Tokko}}'' manga the main story ends after Ranmaru awakens his powers, with the remainder of the manga being a side story focusing on a different set of characters. The anime expands on the events leading up to Ranmaru's awakening and expands/continues the story after he awakens his powers. It also expands on the backstories of most of the characters.
* The ''Manga/TonaGura'' manga chapters that came out well after the anime was done have added depth to the on-screen personalities of the characters. Even militaristic Marie Kagura has a surprisingly sweet if sad motivation for her attacks on her brother Yuuji beyond their father's orders.
* ANY or ALL anime in the ''Anime/WorldMasterpieceTheater'' staple is famous for this, usually for the better (except for ''Remi: Nobody's Girl'', but there are reasons for that).
** ''Anime/PrincessSarah'': While several characters are added or expanded, and the finale is made much more dramatic, the overall story arc is remarkably faithful to [[Literature/ALittlePrincess the original novel]], right down to word-for-word recreations of key scenes -- like Becky's final march up to the attic.
** Other examples are ''Literature/ADogOfFlanders'' and ''Literature/AnneOfGreenGables'' whose stories are not only adapted faithfully, but lots more characters, stories, and conflicts are added, all the way down to really tiny details most people wouldn't even notice thanks to those stories being [[GermansLoveDavidHasselhoff immensely popular in Japan]].
** The novel ''Literature/DaddyLongLegs'' is long and complicated enough to have supported a short anime series -- but when ''World Masterpiece Theater'' picked it up, they turned it into a [[Anime/MyDaddyLongLegs 40-episode series]]. This required expanding some incidents and adding new arcs and new characters. Opinions may vary as to whether the additions were better or worse.
** ''Anime/PeterPanNoBouken'' massively expanded on the mythos of Literature/PeterPan with all the characters occasionally getting the focus on them for at least an episode each, plus a bunch of new characters -- most importantly, the local DarkMagicalGirl Princess Luna and her evil grandmother Sinistra.
** ''Anime/ThreeThousandLeaguesInSearchOfMother'' tells the adventures and misadventures of an Italian boy named Marco Rossi, who goes to Argentina [[IWillFindYou to find his mother Anna]]. The basis for it is a mere ''chapter'' of the book ''Cuore'' by the Italian writer Edmondo D'Amici, so the series itself takes the basic idea and timeline and builds a whole story from there by inserting SliceOfLife episodes with Marco and his remaining family (his father Pietro and older brother Tonio) preparing for the travel, Marco befriending a nearby family [[PuppyLove and especially]] the middle daughter Fiorina [[spoiler: and finding them again in Argentina]]), the addition of Marco's [[EverythingsBetterWithMonkeys pet monkey]] Amedio, etc.
** Hector Malot's novel ''[[Literature/NobodysGirl En Famille/Amongst Family]]'' begins with the arrival of the protagonist Perrine, her IllGirl mother Marie and their donkey Palikare to Paris. Its WMT version, ''Anime/TheStoryOfPerrine'', shows ''how'' they traveled there from Bosnia in the first place, gives Perrine a CanineCompanion named Baron, and adds more "meat" to Perrine's travel to the northern village of Maraucourt and her early days there.
* ''Manga/YuYuHakusho'' has several instances of expansion from the manga, as minor plot points can become mini-subplots. In the anime adaptation of the Yukina arc, part of the pressure is to get to Yukina and prevent Hiei from killing Tarukane out of anger, and Hiei is shown prepared to kill Tarukane before Yukina stops him. In the manga, Botan only mentions that it was good that Hiei did not kill Tarukane, or else they would have to arrest him for killing a human, and Hiei only punches Tarukane once after finding him, saying that Yukina is worth more than he is. Come on, Hiei! You can't kill the guy, but readers probably wouldn't blame you for attempting it, considering what Tarukane is...
* ''Anime/TheTaleOfThePrincessKaguya'': The film follows the folktale close enough, but adds more CharacterDevelopment and scenes to flesh out the story more.
* The anime version of ''Manga/RanmaOneHalf'' is a weird case of a series doing this and AdaptationDistillation at the same time. Without going into the abundance of extra stories that were made to flesh out the episode roster, many adaptations of manga stories either trimmed things down or expanded them.
** The Japanese Nanniichuan story, in the manga, ends up a complete bust when Ranma and Ryoga break into a waterline. In the anime, they uncover a strange urn that leads to the next two episodes being an extended FetchQuest that ultimately ends in... an entirely ''different'' ShootTheShaggyDog ending.
** The Martial Arts Tea Ceremony was a particularly weird example. Instead of the manga's version, where Ranma is unwillingly recruited into a farcical battle to save Sentaro Daimonji from [[ItMakesSenseInContext being married to a monkey]], Ranma is instead recruited to prove Sentaro has the right not to be placed in an ArrangedMarriage. He and Akane then run into the Daimonjis in three more episodes; a farcical little encounter, a duel that sees Sentaro engaged to his manga-canon wife and TrueLove Satsuki, and helping Sentaro and Satsuki out with a problem.
** The "Curse of the Scribble Panda" episode pads out the version from the manga, which was only a few pages long, by adding two things: firstly, the other {{yokai}} from the other wall scrolls also come to life, forcing Soun, Genma & Happosai to hold them off. Secondly, when Ranma tries to claim he and the Panda can't be together because they're different species, she [[VoluntaryShapeshifting promptly turns herself into a beautiful human girl]], so Ranma finds himself actually a little attracted to her.
* ''Manga/SgtFrog'':
** Because Giroro, Kururu, and especially Dororo and Koyuki are introduced in the anime much earlier than in the manga, several storylines not featuring them at all were modified to include them.
** Because of the time difference between the start of the manga and the anime, Angol Mois' backstory is somewhat modified. Everything up to the point of Mois telling UsefulNotes/{{Nostradamus}} about her destroying the earth was true but she ended up being five years too late (2004 instead of 1999, 2009 in the Funimation dub).
** Mutsumi (623) still has his radio show in the anime, but he is a student in Natsumi's class instead of a high school dropout. Also the fact that he is the host of the 623 radio show seems to be a secret from Natsumi and other listeners of the show.
** In the manga, Keroro gains access to the Kero Ball early in the plot, but in the anime Fuyuki keeps it. This means that several of the early uses of the Kero Ball in the manga didn't happen in the anime or found other ways to happen. Meanwhile, the anime had its own exclusive story focusing on the Kero Ball.
** In the manga, Sumomo is a female 'Ahotoran' who appears in a bonus chapter, while in the anime Sumomo is a hit intergalactic popstar who appears in several episodes throughout the early seasons of the show. Even after she stops appearing, her presence can still be seen through merchandising and posters featuring her.
** Dororo and Koyuki live in a house next to the Hinata's in the manga, whereas in the anime, they live in the woods near Momoka's estate and can see the Nishizawa tower from their home.
** Many of the Sgt. Frog anime episodes are [[{{Filler}} not found in the manga]].
** In the manga, there's only an impersonal narrator, while the anime uses the narrator as a character who eventually even appears on screen.
* ''Manga/OniisamaE'' is a three-volume manga adapted into a 39 episodes anime, so logically it had quite a lot of this. Fukiko and Rei's past is more expanded on, Fukiko gets a whole episode to herself and so do Aya and her GirlPosse, the Sorority members get bigger roles in the [[spoiler: Dissolution]] arc (specially [[spoiler: "Borgia" Ogiwara]]), Mariko's problems with [[YourCheatingHeart her]] [[ParentsAsPeople parents]] are more focused on towards the end, Tomoko becomes an AscendedExtra [[spoiler: and re-befriends Nanako almost immediately after their fight rather than at the end]], [[spoiler: the DownerEnding becomes a BittersweetEnding]], etc.
* ''Manga/MyHeroAcademia'' gives an expansion of what was an OffscreenMomentOfAwesome in the manga by naturally making that adventure [[ADayInTheLimelight an entire episode for Froppy]].

* ''Art/TheLastSupper'': In Literature/TheFourGospels, the individual reaction of the Apostles to the news of a traitor is not described, and neither is the physical appearance of the Apostles or Jesus. In visualizing the Last Supper, Leonardo uses the personalities of the Apostles as described elsewhere to extrapolate how he thinks they would react and puts the ideas to paint.

[[folder:Comic Books]]
* The ''ComicBook/MegaMan'' comic is turning a series of video games with little more than {{Excuse Plot}}s into a full fledged series.
* ''ComicBook/ArchieComicsSonicTheHedgehog'' was once a continuation of the [[WesternAnimation/SonicSatAM SatAM series]], then it started heavily incorporating the [[Franchise/SonicTheHedgehog Sega continuity]], and then it evolved into a highly extensive adaptation of both continuities, adding its own elements, and filling in many holes left in by both, even though it's still its own continuity.
** As of the reboot, it's now a direct adaptation of the games universe with a bunch of original elements thrown in for flavor, as well as a few lingering [=SatAM=] influences (namely the original Freedom Fighters, though they've been completely overhauled as well).
* The [[ComicBook/PocketGod comic book adaptation]] of ''VideoGame/PocketGod'' not only puts the pygmies on a larger island, but also gives them different personalities and designs to distinguish them from each other. Later in the series, a tribe of female pygmies is introduced, which the video games [[OneGenderRace lack]].
* In ''ComicBook/TheMultiversity'', Creator/GrantMorrison is featuring an ongoing theme of presenting Franchise/{{Batman}} counterparts on each Earth who were all inspired by something besides a bat, as a reference to [[http://imgur.com/a/MkRrg a short story by Martin Pasko]] from ''Batman'' #256. In the context of the multiverse, Scorpion (inspired by a scorpion) is on Earth-41, Stingray (inspired by a stingray) is on Earth-34, Owl (another Bruce Wayne inspired by an owl) is on Earth-35, Shooting Star (inspired by a shooting star) is on Earth-47, and Iron Knight (inspired by a suit of medieval armor to become a literal knight) is on Earth-36. Morrison seeks to pose the question of how far the character can be stretched before they're no longer Batman.
* The comic book adaptation of ''Comicbook/InjusticeGodsAmongUs'' greatly fleshes out and expands the world of the game, and features a much larger cast of characters.
* Likewise, the comic adaptation of ''Comicbook/ContestOfChampions'' features a much more substantive and character-driven story than the LetsYouAndHimFight ExcusePlot of [[VideoGame/MarvelContestOfChampions the video game]].
* ''ComicBook/WarlordOfMars'' and its many spin-offs and limited miniseries are based on Creator/EdgarRiceBurroughs' Literature/JohnCarterOfMars. Certain original storylines that are exclusive to its publisher Creator/DynamiteComics expand on main characters backstories that were not covered in the book, such as ''Warlord of Mars: Dejah Thoris'', a prequel set 400 years before the arrival of John Carter, focusing on the titular heroine (as well as Carter's LoveInterest)'s life and adventures before she met the Earthman.
* ''ComicBook/DisneyDucksComicUniverse'': Creator/CarlBarks' comic book adaptation of the WesternAnimation/DonaldDuck short "Trick or Treat" expands a bit on why Donald is so mean to his nephews (he hates Halloween because of trick-or-treaters interrupting his privacy), and adds a few extra gags (like Witch Hazel disguising herself as an attractive lady duck, and later summoning a monster to steal Donald's candy).
* ''ComicBook/MortadeloYFilemon'': In the 1988 album "Los sobrinetes" (The Little Nephews), Mortadelo and Filemón coincidentally introduce their nephews, [[UncannyFamilyResemblance who look exactly like them]], and wear exactly the same clothes but with short trousers, [[{{Nephewism}} with no introduction or even mention of their parents]].

[[folder:Eastern Animation]]
* There is a Soviet cartoon called [[http://www.youtube.com/watch?v=bpx4dxR01J0 Pif-Paf, Oi, Oi, Oi]], where an eight line children verse is adapted to five different theatre styles. As an interesting subversion, one of the adaptations is actually a CompressedAdaptation using the music from Music/JesusChristSuperstar.

[[folder:Fan Works]]
* ''Fanfic/ABoyAGirlAndADogTheLeithianScript'': This fic retells a story from ''Literature/TheSilmarillion'' that in the original book was thirty pages long (the prose version), and around one hundred pages long in ''Literature/TheHistoryOfMiddleEarth'' (the Lay version). This fic is more than half a million words long.
* Much of the entire first half of ''Fanfic/CodeGeassMaoOfTheDeliverance'', along with detailed explanations set in between {{canon}} ''Anime/CodeGeass'' episodes.
* The ''FanFic/CodeMarsTrilogy'' FusionFic also expands on some minor ''Anime/CodeGeass'' characters, notably Taizo Kitihara.
* ''Fanfic/CalvinAndHobbesTheSeries'' shows a much more complex world than the [[ComicStrip/CalvinAndHobbes comic strip it was based on]].
* Certain elements of the ''Franchise/SonicTheHedgehog'' games, comic books, or animations are usually introduced then promptly ignored. ''Blog/AlwaysHavingJuice'', a AlternateUniverse CharacterBlog that's based in a different continuity takes those elements, uses them and expands upon them in ways impossible for the source materials to touch.
* ''FanFic/HereWeGoAgain'' takes the web novel ''[[Literature/{{Gate}} Gate - Thus the JSDF Fought There]]'' and brings the United States Marine Corps into the mix by introducing [[TankGoodness tankers]] as the main cast.
* ''Fanfic/TheLegacyOfTheBloodRavens'' takes the plot of various ''VideoGame/DawnOfWar'' games and expands the cast of 20 or so characters to more than fifty, covering dozens of events more than the games themselves as well as getting perspectives from each of the races involved.
* ''Fanfic/GameTheoryFanFic'' massively expands upon the setting of ''Franchise/MagicalGirlLyricalNanoha'', providing an incredibly rich, detailed history and comprehensive rules for the magic.
* ''Lady Prismia and the Princess-Goddess'', the second story in the FanFic/CadanceOfCloudsdale anthology, takes [[Literature/TwilightSparkleAndTheCrystalHeartSpell the one paragraph of]] Cadance's origins and turns it into an entire story, though some liberties are taken to stay consistent with the first story (such as Cadance already being an [[WingedUnicorn Alicorn]], instead of a pegasus that gained her horn in said origin story).
* The ''WesternAnimation/TotalDrama'' reimagining, ''Fanfic/TheLegendOfTotalDramaIsland'', is not constrained to 20-minute segments like the original, and exploits this freedom by including much more personal byplay and additional ancillary scenes. The result is a more character-driven story than the original.
* [[http://quarma.deviantart.com/art/Second-TG-Recreated-145000862 One sentence and one drawing were the basis for]] ''Sonic's New Look,'' which encompasses two full stories so far.
* ''Fanfic/SaetwosStory'' is a fan {{novelization}} of the old {{edutainment}} classic ''VideoGame/LogicalJourneyOfTheZoombinis''. Since the game itself has very little unique material, the author gave distinct personalities to each of the Zoombinis and fleshed out their interpersonal interactions, expanded on parts of the story that were only hinted at (such as life on Zoombini Isle before the Bloats took over, and the harrowing journey to the next continent) and {{Re Tool}}ed the Fleens from one-off MirrorMatch enemies to the real {{Big Bad}}s of the setting, culminating in [[spoiler:a FinalBattle in the last area between the Fleens and Zoombinis that never occurs in gameplay]].
* Klar Ken was a Franchise/{{Superman}} direct descendant who showed up in a few Silver Age stories (Action Comics #338-339 and World's Finest #166). ''Fanfic/SupermanOf2499TheGreatConfrontation'' is a multi-part epic that develops the character and his family, greatly expands on his world and tries to connect it with the ''ComicBook/{{Legion Of Super-Heroes}}''.
* The ''FanFic/EmpathTheLuckiestSmurf'' story "The Smurf Of Solomon" is both this and a PragmaticAdaptation of the Song Of Solomon from Literature/TheBible, given that the original work is a series of love poetry.
* ''FanFic/ChildOfTheStorm'' is this. In addition to adding in many new characters from multiple sources, it also has different interpretations of some of the characters and gives them more backstory.
* As a {{novelization}} ''Fanfic/BaitAndSwitchSTO'' expands greatly on the 1-2 hour-long ''VideoGame/StarTrekOnline'' Foundry mission [[Recap/StarTrekOnlineFoundryBaitAndSwitch of same name]]. The most prominent addition is the USS ''Bajor'' and crew, standing in for the PlayerCharacter, and various scenes involving them that take place around and between the mission's various stages.
* ''FanFic/MegaManRecut'' expands the world of Ruby-Spears' Mega Man, especially "Bot Transfer," "Future Shock," and "The Mega Man in the Moon."
* ''FanFic/MegaManDefenderOfTheHumanRace'' combines elements from the Ruby-Spears Mega Man show and the games, and continues beyond the cartoon.
* ''FanFic/TheStalkingZukoSeries'' expands the time span passed inbetween ''WesternAnimation/AvatarTheLastAirbender'' episodes after Zuko joins the Gaang to expand the growth of Katara's relationship to Zuko, Zuko's relationship to the Gaang and Suki's CharacterDevelopment.
* ''FanFic/TheGamesTent'' expands upon the ''WesternAnimation/AaahhRealMonsters'' episode "The Monster who Came In from the Cold", detailing more about Oblina's time undercover as a human as well as the aftermath.
* ''Fanfic/LegacyOfChRihan'' is a novelization of the Romulan tutorial in ''VideoGame/StarTrekOnline'', and the first chapter is actually set a few hours before the tutorial missions. It also contains sub-chapters set just after Hobus, detailing how main character Morgan t'Thavrau ended up on Virinat in the first place.
* ''FanFic/{{Shatterheart}}'' expands the Infinity and Nihon Arcs of ''Manga/TsubasaReservoirChronicle'', detailing the emotional fallout of [[spoiler:Clone Syaoran's betrayal and Real Syaoran's rocky integration into the group]] and for the sake of [[AvertedTrope averting]] HollywoodHealing and [[RealityEnsues give a realistic timespan for serious wounds to heal.]]
* ''Fanfic/TheWrongReflection'' is a {{novelization}} of a ''VideoGame/StarTrekOnline'' mission, "The Other Side", that takes maybe twenty minutes to play. The MirrorUniverse doesn't even get a mention until more than three-quarters of the way through the first chapter, much of which concerns Eleya's sister's wedding instead.
* ''Fanfic/FightForTheLost'' is a fan {{novelization}} of ''VideoGame/MassEffect2'' and expands or reimagines various scenes throughout the game and provides greater development or backstory for many of the characters, and at times even [[OriginalCharacter adding new characters from scratch]].
* ''Fanfic/AVoiceAmongTheStrangers'' is the story of Jessica, a university student transported to [[WesternAnimation/MyLittlePonyFriendshipIsMagic Equestria]] and her struggle to overcome the language barrier between her and the ponies. The POVSequel, ''A Stranger Among the Voices'', has four viewpoint characters (so far, and one of those has yet to actually meet her), and a lot of direct dialogue that Jessica couldn't understand when she heard it. As a result, it has taken over 118,000 words to cover the timespan of the first two chapters of the original story (just over 28,000 words altogether), not counting the 10,000 word first chapter, set before Jessica entered the story.
* ''FanFic/HyruleWarriorsHeroesThroughTime'': The fic follows the game's plot, but adds additional content, such as the Time Gazers, a clan of time-controlling witches that Cia belonged to, as well as adding in Groose, Pipit, and Scrapper during the Skyloft chapter.
* ''FanFic/KidIcarusUprisingTheNovelization'': Though it follows the game's plotline closely, it adds in additional scenes and dialogue to further flesh out the story, such as giving Pyrrhon a FreudianExcuse as to why he tried to hijack the Aurum.
* ''FanFic/ALinkBetweenWorldsTheNovelization'': While it follows the story of the game closely, it also adds in scenes of Yuga actually capturing the Sages, while in the game, his doing so was mostly OffstageVillainy.
* ''FanFic/BadFutureCrusaders'' provides an interesting variation: it started as a [[http://astringe.deviantart.com/gallery/41135018 series of images]] from Website/DeviantArt that showed characters from ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' in a BadFuture scenario. From that it was adapted by a Fimfiction user who wrote a plot that tied the images together.
* ''Fanfic/OhRhonda'' is an interesting example in which the episodes are talked about, but expanded into a more full-fledged StoryArc.
* The ''FanFic/HyruleWarriors'' novelization by [=MiniJen=] follows the game's storyline closely, but adds in additional elements and characters, such as having Karane, Pipit, and Groose appear in the Skyloft chapters and Ilia and the Ordona village children appear in the Twilight chapters, and giving Link an expanded backstory.
* ''[[http://www.fimfiction.net/story/166077 LEGO Equestria Girls]]'' is more than just ''WesternAnimation/MyLittlePonyEquestriaGirls'' [[RecycledINSPACE in a]] {{Franchise/LEGO}} setting. For starters, the story does not take place in a high school. (Flash Sentry also has more into the plot than being just Twilight's love interest, which he isn't even in this story.) By extension, [[http://www.fimfiction.net/story/245599 the sequel]] is also more than just ''[[WesternAnimation/MyLittlePonyEquestriaGirlsRainbowRocks Rainbow Rocks]]'' in a LEGO setting.
* Two stories of FanFic/TheNonBronyverse are like this, one with a canon work, and one with a fanon work.
** ''TD vs. Equestria Girls'' deviates from the storyline seen in ''WesternAnimation/MyLittlePonyEquestriaGirls'' by having TD go through the portal instead of Twilight (after all, TD's the alicorn instead of Twilight). Of course, TD being TD, a series of events occur against him that culminate in [[CallBack TD punching Principal Celestia in the face]]. And then punching Mr. Antares. Who is an alternate version of himself. Yeah, that ended badly.
** ''TD's Little Rarity'' deviates from the storyline seen in ''FanFic/MyLittleDashie'' due to, unlike the protagonist of MLD, TD having a lot of people around him who could find out around Rarity. And most of them are bronies. It goes as well as you'd expect: TD and Rarity being taken away by the government.
* ''Fanfic/BeatTheDrumsOfWar'' is a {{novelization}} of the ''VideoGame/StarTrekOnline'' mission [[http://sto.gamepedia.com/Blood_of_the_Ancients "Blood of the Ancients"]]. In addition to the canon battle scenes, the Iconians also hit several other planets. {{Enforced|Trope}} because the authors were in the section of STO's playerbase that [[TheyWastedAPerfectlyGoodPlot were profoundly disappointed with the limited canonical portrayal of the Iconian War]].
** They attack [=Qo'noS=] and are challenged by a fleet led by Chancellor J'mpok (stated to be inspired by the STF "Gateway to Gre'thor"). [[spoiler:The IKS ''[=Bortasqu'=]'' is knocked out in the first volley, J'mpok's flagship is trashed, and the day is only saved by Brokosh, Ja'rod, and Worf leading a ragtag fleet of vassal races, mercenaries, and dishonored warriors in a surprise attack on the Heralds' flanks.]]
** Tuvok gets the Undine to help out when the Heralds attack Vulcan, completing the HeelRaceTurn from ''Fanfic/RealityIsFluid'' and "[[http://sto.gamepedia.com/Mission:_Mindscape Mindscape]]".
** The Iconians land on Bajor and are met by the full force of the Bajoran Militia. [[spoiler:Turns out Herald Harbingers are no match for main battle tanks. Oh, and then Dominion forces led by Odo join in.]]
** A joint Romulan/Delta Quadrant force stays behind to defend New Romulus against a renewed Herald attack. [[spoiler:Then the Romulan Star Empire joins in as TheCavalry.]]
** The Iconians attempt to attack
** Another battle is mentioned at Tellar, while the Cardassians withdrew to Cardassia Prime in expectation of an attack that never came.
* ''Fanfic/TheElementsOfFriendship'' does this with ''WesternAnimation/MyLittlePonyFriendshipIsMagic'': The first Book takes the two part pilot and turns it into a {{Doorstopper}} epic, the first Interlude takes the episode "Magic Duel" and expands on it significantly, and it's implied the whole series will continue to follow this pattern.
* ''Fanfic/FairyWithoutWings'' is working on covering ''a lot'' of ground during the absence of Fairy Tail following the events of Tenrou Island. Rather than skipping ahead 7 years, the writer has given Kagura Mikazuchi a full out backstory and has even dedicated time to fleshing out Sabertooth and showcases the Grand Magic Games of how they got so popular in the first place. Granted, since this is a crossover, things have changed [[spoiler:Such as Sabertooth being under the command of Suzaku Kururugi after he arrests Jiemma]]. And on a lesser note, the very premise of the fic was designed to show points in the mage world of Earthland that ''should'' come with the territory of such a world, [[SlidingScaleOfIdealismVsCynicism but that Mashima flat out ignores or only barely hints at existing]]. These are things that [[PayEvilUntoEvil Lelouch]] would normally be seen doing on a regular basis.
* In the last episode of ''Anime/{{Gungrave}}'', Biscoe is seen to dismiss Mika coldly after she begs him to take her to Brandon, knowing that Brandon is siding with Harry and has to die. He later has a change of heart and decides to stop the attack on (possibly) Brandon. When the show ends, the screen is black, but we can hear Mika saying, "Welcome back." It's not specified whether Mika is referring to Brandon in the afterlife or he does survive the ordeal. [[https://www.fanfiction.net/s/11664227/1/Decisions-Consequences-and-a-Second-Chance Decisions, Consequences, and a Second Chance]] expands upon those parts:
** Because Brandon has betrayed Millennion, according to the Code of Iron, he has to die. Biscoe does pity Mika for being an orphan who is about to lose her ParentalSubstitute, but at the same time, he is a stickler to the Code of Iron. But after seeing that one of his guards is being bitten by Mika for restraining her from going out of the building and reaching Brandon at the slum, Biscoe is realizes that it's Mika's instinct of being an orphan. She is very afraid of losing her ParentalSubstitute, and this realization leads to Biscoe's change of heart.
** The way Biscoe tries his best to save Brandon is also explained in detail.
*** For starters, he calls his man to fetch Dr. Tokioka's trailer and a doctor from the research facility (the one who explains to Biscoe about Anti-Necrolyze bullets in episode 25).
*** Biscoe ordering his men to stop the attack is expanded upon and provides the explanation of why he suddenly yells at the phone. It turns out that his men seemingly refuse to listen to him.
** Mika saying 'welcome back' is revealed to be the moment she discovers that Brandon survives the ordeal after having been presumed to be [[DisneyDeath dead]] earlier.
* The vocaloid fic ''Fanfic/RottingCamellias'' expands on the song ''Dark Woods Circus,'' giving backstory to many of the characters and the circus itself.
* In ''Fanfic/TheLittlePonyLegend'', the fanfic's version of Friendship Games gives Team Avatar a major role to play as well as an alternate explanation to why Princess Twilight could not go through the Portal, which is that it reacts abnormally when Human Twilight comes into contact with it during her investigations. It also expands on Legend of Everfree, giving Kuvira a major role in the plot and expanding more on Gloriosa, Timber, and human Flash.
** Korra's character is given additional traits as she interacts with the Mane Six.
** The entire [=LoK=] storyline is incorporated into [=MLP:FiM=], taking place at certain points during Season 4 or near Season 5 and 6. Many things are added either to incorporated the [=FiM=] characters or to maybe expand on certain characters' actions via narration.
** Mako's backstory is explored in "The Nightmare's Return" and displays the character growth he went through the Legend of Korra much more clearly.
** Earth Queen Hou-Ting's character is given a fairly sympathetic backstory as well as a new lease on life in Book 3 and beyond.
** Kuvira meets and befriends Korra during the Avatar's stay in Zaofu, adding more weight to their conflict in "Balance of the Heart." All while keeping true to Book 4's storyline as a whole.
** Starlight Glimmer's backstory as shown in ''The Cutie Remark'' is expanded upon to show how she and Sunburst grew further apart in the time that passed since the latter got his Cutie Mark.
** The fic's version of ''The Crystalling'' expands on Starlight's role while giving the role of Sunburst to his father.
* The ''{{VideoGame/Undertale}}'' fanfic ''[[Fanfic/UndertaleFanNovelization Undertale]]'' is a {{Novelization}} that retells the events of the video game while expanding on the events, characters, and even enemies who you meet in the game.
* The ''Manga/SoulEater'' fanfic ''Fanfic/SoulEaterTroubledSouls'' features a more complex setting than the original material due to the author taking aspects of it and running with them or adding in his own, original touches.
* The famed fanfic ''FanFic/AuroraFalls'' introduces many new concepts to the world of ''{{Videogame/Subnautica}}''.
* In ''Fanfic/{{Intercom}}'', it's impossible to tell if it will turn out to be longer than the original work since print and film are entirely different mediums. However, the author has gone on record that she'll be using several InsideOut abandoned concepts in her story to give it more flavor as well as her own interpretations of things. These include Riley's relative size compared with her emotions (see Huge Schoolgirl below), how Riley got a new Hockey Island from a core memory made by Joy and Anger, or all the metaphysics connecting the mind world to the real world and what happens when a host comes in.
* In the ''Manga/{{Naruto}}'' fanfic ''FanFic/SugarPlums'' this is done extensively to the Land of Water, going into the set up of the shinobi system, the political and economical structure, the reasons and events that led up to the desertion and deaths of the seven swordsman, the reasons why the Kaguya attacked Kirigakure and how Mei got into power.
* [[https://www.fanfiction.net/u/505953/Naryfiel-Lilith Naryfiel Lilith]], a fanfic writer who mainly focuses on VideoGame/FireEmblem (as of writing this in April 2017), does this in almost all of her stories. Her four-part [[VideoGame/FireEmblemElibe Elibe]] series in particular expands on the games by adding various characters, locations, lore behind items such as the [[CoolSword Sword of Seals]], and even what caused the Scouring!
* ''Fanfic/ATriangleInTheStars'' is set after the aftermath of ''WesternAnimation/GravityFalls'' and after "Ocean Gem" in ''WesternAnimation/StevenUniverse''. It becomes a sort of AlternateUniverse after that, however.
* ''Blog/ThePredespairKids'' expands on '''a lot''' on the setting of ''Franchise/{{Danganronpa}}'', from exploring the history of the school to characters [[WeHardlyKnewYe who didn't get as much screen time as they could have]]. The sequel series, ''The Despair Kids,'' takes this even further by expanding on the criminally underdeveloped [[Anime/Danganronpa3 Future Foundation characters]]. Probably the best example is Miaya Gekkougahara, whose only noteworthy feature in the anime is her being [[TheSpeechless quiet]] and [[ShrinkingViolet painfully shy]]. Here, she's actually given a real voice (which she prefers to use around close friends), a personality, a backstory, relationships, and her own personal struggles.
* {{Creator/madsthenerdygirl}} expands on the events of ''Film/CaptainAmericaCivilWar'' into three different installments in her ''Fanfic/MCURewrites'': ''[[http://archiveofourown.org/works/11613867 New Avengers]]'' which focuses on Wanda and Pietro Maximoff/Scarlet Witch and Quicksilver, Vision, James "Rhodey" Rhodes/War Machine, and Sam Wilson/Falcon becoming the [[ExactlyWhatItSaysOnTheTin New Avengers team]]. [[spoiler:Tensions involving the Sokovia Accords begin to rise when Wanda nearly kills Tomi Shishido/Gorgon for [[YouKilledMyFather killing Pietro]].]] ''[[http://archiveofourown.org/works/11652534 Captain America: Ghosts of HYDRA]]'' which focuses on Steve Rogers and Sharon Carter finding James "Bucky" Barnes/The Winter Soldier and bringing him back from his brainwashing and taking down the remnants of HYDRA. [[spoiler:There is also a fight between Sharon Carter and another one of the Winter Soldiers, Josef in the climax of the story. Steve and Tony's friendship is nearly broken when Tony discovers, through the use of his Binarily Augmented Retro Framing device that [[YouKilledMyFather Bucky killed Maria and Howard Stark]] [[BrainwashedAndCrazy while under the control of HYDRA]].]] ''[[http://archiveofourown.org/works/11652651 Avengers: Civil War]]'' focuses on the team being split by the Sokovia Accords and the pro- and anti- registration sides being put into conflict when Bucky and Wanda are accused of a terrorist attack. [[spoiler:There is also a sequence of events that shows Maria and Sharon breaking a few members of the anti-registration side out of their prison. The final scene shows Heimdall and Thor observing these events with Thor making it clear that the Avengers will be brought back together because a war is coming, [[Film/AvengersInfinityWar a war that is... infinite]].]]
* ''Fanfic/ExtraLife'' does this for the world of ''Franchise/{{Danganronpa}}'', taking it upon itself to fill in vague canon details by offering {{Worldbuilding}} about the time of the Tragedy and the Future Foundation, explaining the Neo World Program's construction, giving screentime to underused characters like Miaya, and resolving what happens to [[VideoGame/AbsoluteDespairGirls the Towa City captives]].
* The War of Conquest goes from an unseen event in the backstory of ''Literature/ASongOfIceAndFire''/''Series/GameOfThrones'' to the main conflict of Books 2 and 3 of ''Fanfic/ForumOfThrones''. Additionally, many characters who are at best [[PosthumousCharacter posthumous characters]] in the source material are major characters here.
* ''Fanfic/PokemonResetBloodlines'' does this a lot. Many characters, locations, and concepts are given a lot more history and details on their pasts than the anime, games, or manga did. Examples include:
** Infernape's super strong Blaze ability is now a recognized condition called Hyper-Blaze (which is hinted to come in other variants like Hyper-Overgrow or Hyper-Torrent).
** Many parks hold Bug-catching Contests like the one seen in Johto. It's been featured in Kanto, Sinnoh and Unova so far.
** The Battle Frontier is featured while it's still in its formation stage, with only five Frontier Brains recruited.
** Characters of the day appear earlier and more often, and we get to see bits and pieces of their past. [[AscendedExtra Several of them have gone on to star]] [[ADayInTheLimelight in their own sidestories]].
** We get to see the early actions of Cipher before they implement their plans, including recruiting Dakim and seeking out rare and powerful Pokemon to be made into Shadow Pokemon.
** Some facts from the Sun and Moon Pokédex are expanded upon, such as the how Mudbray line was once found worldwide but is now rare, and in fic we see people working to reintroduce the species to Kanto's Safari Zone. Likewise, the same Pokedex mentions that Skarmory Feathers were used as swords, and a sidestory comments of how they were used.
** The Kiawe oneshot explains that the Tapus can give people [[ATasteOfPower one-use Z-Crystals to let them test their power]]. This is explained as the reason why Ash's Z-Crystal broke in Episode 2 of the SM series.
** Rotom are able to possess Pokedexes that aren't specifically made for them. It's just a lot less effective.
** Technical Machines, or TMs, are featured in the story as Technical Manuals, in the form of USB drives that can be plugged to any computer. They contain tutorials about how to teach Pokémon different moves and can be updated regularly.
* The ''Fanfic/PonyPOVSeries'' does this to all four animated series in some capacity, due to [[CanonWelding merging all four into one timeline]]. This includes providing epilogues to the original two TV series that show how they tie together, provide a FinalBattle for G1 in the form of the Witch War, and in the case of G4 provides expansions on canon events to explain things better or fill in plot holes, or even turn two episode finales into entire story arcs.
* ''Fanfic/EquestriaAcrossTheMultiverse'':
** The world of ''WesternAnimation/MyLittlePonyTales'' is visited, with the arc set post series. The world is explored more and ultimately joins the multiversal Alliance, the resulting {{Magitek}} creating a tech boom.
** My Little Pony G2 had no AnimatedAdaptation and the comics were largely SliceOfLife with biocards containing the majority of the information. When the world is visited, the author of that particular universe combined the comics, biocards, and video games together to create an approximation of what an animated series might be like while also performing CanonWelding to make it a direct sequel to G1, with Megan being the 'player' of the ''VideoGame/MyLittlePonyFriendshipGardens'' (which is an OrphanageOfLove run by her) after [[RetiredBadass she and the Paradise Ponies vanquished all of Ponyland's evils and brought about peace]], and some form of story arc involving Sundance eventually becoming Queen Sunsparkle happened.
* In [[WesternAnimation/{{Trollhunters}} the show]], Barbara is established to be a doctor while her husband is implied to have been a part of the military. In ''Fanfic/ChangingWays'', she’s a military M.D., which may explain how they met in the first place.


[[folder:Films -- Animated]]
* ''WesternAnimation/ThePolarExpress'' movie, which some critics and audience members complained felt like a 20-minute short with an hour of filler added onto it. That certainly doesn't stop it from grabbing at your heartstrings, though, and the animation is quite breathtaking, too.
* The film adaptation of the Hudson Talbott children's book ''WesternAnimation/WereBackADinosaursStory'', transformed a simple FishOutOfWater tale about large prehistoric creatures dropped into the strange new setting of modern-day New York into a full-blown Disneyfied epic. The dinosaurs got some new friends in the form of runaway disillusioned children, an [[CircusOfFear evil circus owner]] and his Cereal That Makes You Evil (seriously). Walter Cronkite also voices a scientist who gives them a mission of "making children's dreams come true". This is meant to save the world. Somehow.\\
It is well worth it to hunt around for Talbott's sequel book, ''Going Hollywood''. The story has Rex and pals go to Hollywood to have their life story made into a movie. Much hilarity ensues. [[WriterRevolt One can't help but wonder...]]
* All of Disney's fairy tale-based films fall under this trope by default as the original fairy tales are typically rather short and simplistic, requiring a good amount of character and plot expansion to stretch them out to an hour and half. ''Disney/SnowWhiteAndTheSevenDwarfs'' padded out its length with several dwarf-centric scenes, ''Disney/SleepingBeauty'' greatly expanded the roles of the fairies and gave the prince something to do other than be lucky enough to be standing in front of the thorns just as the century-long spell expired, ''Disney/{{Tangled}}'' has Rapunzel spend more time outside her tower than inside it for the film's running time, etc.
* Disney's ''Disney/{{Dumbo}}'' was based on a very short (thirty-six pages) children's book. Even with a decent amount of padding, the final film clocks in at only sixty-four minutes. They could've done without "[[DisneyAcidSequence Pink Elphants on Parade]]," though.
* ''WesternAnimation/{{Coraline}}'', adapted from the original [[WhatDoYouMeanItsNotForKids children's book]], makes several significant changes. Most notable are the addition of Wybie, a neighbor boy who turns out to be the grandson of the woman who owns the house and a friend of the Black Cat. The bit with the rag doll is also a movie-only inclusion. The movie also expands on the identity of [[spoiler:one of the little girls in the Room Behind The Mirror]] and her connection to movie-only Wybie, it also completely erases the implication that the Other Mother is one of TheFairFolk whose realm is [[ParanoiaFuel not the only one out there]]. The biggest discrepancy here is that in the book, that little girl isn't human, she's a pixie, and the Beldam's first victim.\\
According to WordOfGod, director Henry Selick added Wybie in as he thought [[NecessaryWeasel it would feel odd with just Coraline talking to herself through half of the film,]] which in fact adds a certain poignancy to the question, "Why were you born?"
* ''WesternAnimation/MrPeabodyAndSherman'' is based on the ''Peabody’s Improbable History'' segments barely over five minutes lone from ''WesternAnimation/RockyAndBullwinkle''.
* ''WesternAnimation/CloudyWithAChanceOfMeatballs'' expands from original children's book about falling food getting out of proportion, to a movie about a quirky scientist who creates an invention that turns water into food, his troubling relationship with his father after the death of his mother, Chicken Brent!, the evil obese mayor, sparking love interest between inventor and secret geek female weather reporter, MR. T!, Monkey!, Ratbirds!, Sardines!, etc...
* ''Disney/MeetTheRobinsons'' added a whole time travel plot around the children's story ''A Day With Wilbur Robinson''. The second act, where Lewis meets the Robinson family and looks for Grandpa's teeth, is the only part of the movie that's actually in the book.
* Creator/TimBurton's ''WesternAnimation/CorpseBride'' was initially a mere short story that he penned (itself based on a folk tale), then expanded upon.
* ''WesternAnimation/TheNightmareBeforeChristmas'' likewise started as a poem by Tim Burton.
* Almost all of the ''Franchise/{{Barbie}}'' movies are this, seeing most of them are based off of short tales, such as ''WesternAnimation/BarbieInTheNutcracker,'' ''WesternAnimation/BarbieOfSwanLake'', ''WesternAnimation/BarbieInTheTwelveDancingPrincesses,'' etc. In ''WesternAnimation/BarbieAsRapunzel'', the original story is a DreamSequence.
* ''WesternAnimation/YellowSubmarine'', which expanded a Beatles song into a movie.
* ''WesternAnimation/{{Shrek}}'' was originally a children's book that contained almost nothing that appears in the film. Somehow, we ended up with four movies (the first two critically-acclaimed) and a [[Theatre/ShrekTheMusical Broadway musical]].
** And then Puss in Boots became an AscendedExtra and got his own hilarious spinoff movie.
* The original ''WesternAnimation/{{Frankenweenie}}'' was 30 minutes. When Creator/TimBurton revisited it years later, he turned it into a 87-minute film with a subplot involving other kids using Victor's formula to turn their own dead pets into animal versions of classic movie monsters ({{and|Zoidberg}} Franchise/{{Gamera}}), culminating with Mr. Whiskers (the vampire cat) being involved in the climatic windmill scene.
* ''WesternAnimation/{{Epic}}'' is a loose expansion of ''Creator/WilliamJoyce'''s The Leaf Men and The Brave Good Bugs.
* Similar to the live-action ''Film/TheTenCommandments'', ''WesternAnimation/ThePrinceOfEgypt'' expanded upon the details in the Literature/BookOfExodus to show the relationship between Moses and the Pharaoh. Both films depict it as SiblingRivalry. Nothing in scripture itself says Moses and the Pharaoh were raised as brothers.
* Creator/RoaldDahl's children's novel ''Literature/FantasticMrFox'' was [[WesternAnimation/FantasticMrFox adapted]] by Creator/WesAnderson. Much of the expansion comes in the form of focusing on the animals' plans to evade the farmers, the relationships and [[CharacterDevelopment development]] of characters. It also gave Ms. Fox [[NominalImportance a name--]][[spoiler:Felicity]]. The ending to the movie was found in Dahl's archives.
* ''WesternAnimation/BatmanTheKillingJoke'', based on [[ComicBook/TheKillingJoke the comic of the same name]], includes a prologue to help expand the runtime of the movie and (ostensibly) set-up the story, including a focus on Barbara Gordon's time as Batgirl. This actually wound up being pretty unpopular, as the opening forty minutes have little connection to the main story and feature some...[[CoitusEnsues questionable choices in characterization]].
* ''WesternAnimation/SupermanVsTheElite'' stretches out a single-issue comic book story into a 76 minute film. The writers compensated for the short length of the original comic by adding in a TroubledBackstoryFlashback for Manchester Black, a subplot concerning Atomic Skull and expanding on Black's and Lois Lane's relationships with Superman.
* ''WesternAnimation/TubbyTheTuba1975'', based on the 1945 song of the same name, adds more scenes such as Tubby joining the circus and then visiting the Singing City.

[[folder:Films -- Live-Action]]
* The film adaptation of ''Film/TheGiver'' mentions The Ruin, although that wouldn't be discussed in the books until ''Literature/GatheringBlue.'' The mechanism on how [[spoiler:Jonas's memories are shared with the community when he leaves]] is handwaved as being a technological force field he has to pass to release the memories, where in the book, it just happens with no real explanation.
* Any feature-length film based on something that was written by Creator/DrSeuss.
** Infamously, Creator/RonHoward's feature film adaptation of ''Film/HowTheGrinchStoleChristmas''. The Creator/ChuckJones [[WesternAnimation/HowTheGrinchStoleChristmas animated Christmas special]], which was 25 minutes long, ''still'' had to pad its length with original songs and cute cartoon slapstick to fill the timeslot. The Ron Howard film was ''four times as long'' as the special.
** ''Film/TheCatInTheHat'', which was poorly received and prompted the trope's quote. Interestingly, the film inspired [[RecursiveAdaptation a book adaptation]] that included some of the new material created for the film. In other words, it's an AdaptationDistillation of an Adaptation Expansion.
** Blue Sky's computer-animated ''WesternAnimation/HortonHearsAWho'', on the other hand, actually doesn't stray too far from the limited source material, although there are still tons of added elements, notably an anime-styled scene in the middle and a sudden CrowdSong at the end.
** ''WesternAnimation/TheLorax'' adds additional characters and expands beyond the book's original ending as the boy ([[NamedByTheAdaptation now named Ted]]) attempts to carry out the Once-ler's wishes. But in a disturbing twist, the Once-ler is portrayed as human...and here comes the [[{{Anvilicious}} aesop anvil]] on schedule.
* The live-action ''Literature/PippiLongstocking'' movies added material to the sequence of stories in the books. The third one, ''Pippi in the South Seas'' did indeed have them going to the South Seas--not to visit Pippi's father's island, but to rescue him from pirates.
* ''Franchise/PiratesOfTheCaribbean'' is based on a [[Ride/PiratesOfTheCaribbean theme park ride]], albeit Disney's fan favorite theme park ride since the '60s. It has since become a case of recursive adaptation: the ride now features Captain Jack Sparrow.
* Hollywood turned ''The Secret Life of Walter Mitty'' from a [[Literature/TheSecretLifeOfWalterMitty classic short story]] by Creator/JamesThurber into an [[Film/TheSecretLifeOfWalterMitty1947 overblown Danny Kaye vehicle]].
* The [[Film/{{Bean}} movie]] [[Film/MrBeansHoliday adaptations]] of ''Series/MrBean'' showed that the task of writing a plotline for a SketchComedy character is not an easy one.
* Many ''Film/SaturdayNightLive'' characters have transitioned from SketchComedy to feature films: ''Film/TheBluesBrothers'', ''Film/WaynesWorld'', ''It's Pat'', ''Stuart Saves His Family'', ''Film/{{Coneheads}}'', ''Film/ANightAtTheRoxbury'', ''Film/{{Superstar}}'', ''Film/Ladies Man'', and ''Film/MacGruber''. Some became classics, others, uh...didn't.
* The ''Film/{{Jumanji}}'' movie, which had a far more complex plot than the children's book it was based on. The same goes for the film adaptation of ''Literature/{{Zathura}}'', ''Jumanji'''s SpiritualSuccessor.
* ''Film/SevenBridesForSevenBrothers'' is an example of this done well, following the very short story closely, but expanding on it greatly. For example, the story's title, ''Sobbin Women'', becomes the title of one of the songs.
* ''Film/TheTenCommandments'' undeniably has more to do with Moses's love life than the ten commandments -- not for a lack of source material (about the commandments, not Moses' love life).
* Creator/NicolasRoeg's ''Film/DontLookNow'' follows the plot of the original Daphne [=DuMaurier=] short story fairly closely, but greatly expands minor details and subplots, and changing the BackStory.
* Several ''Film/JamesBond'' movies, such as ''Film/{{Octopussy}}'' and ''Film/TheLivingDaylights'', are expansions of short stories from ''Literature/OctopussyAndTheLivingDaylights'' by Creator/IanFleming. However, those two are somewhat unusual cases. The film of ''Octopussy'' is actually designed as a sequel to the short story (which is completely explained by the title character, so viewers wouldn't need to do homework), while ''Film/TheLivingDaylights'' covers the story's material about Bond helping a defector in its first act, then goes on to have the defector captured among several other plot twists.
** ''Octopussy'' also includes the plot of another story as well, "The Property of a Lady".
** Another movie is a mishmash: ''Film/ForYourEyesOnly'', a combination of [[Literature/ForYourEyesOnly the eponymous story and "Risico"]] (Melina and Gonzales from the former, Kristatos and Columbo from the latter), along with a scene from ''Literature/LiveAndLetDie'' (not used in the earlier movie of that name), plus many original elements.
** ''Film/LicenceToKill'' is another mishmash, using elements from the short story [[Liteature/ForYourEyesOnly "The Hildebrand Rarity"]] and, once again, the novel ''Literature/LiveAndLetDie''.
** ''Film/QuantumOfSolace'' takes one scene from the short story [[Literature/OctopussyAndTheLivingDaylights "007 in New York"]], and no scenes from [[Literature/ForYourEyesOnly "Quantum of Solace"]]!
** The burlesque ''Film/CasinoRoyale1967'' actually played out the original novel's story, after a fashion, but that only took up about a tenth of the running time, the rest of it going off in several bizarre tangents.
*** The more recent adaptation also plays out the novel's story, but also has Bond involved in the events that lead up to the game (not the case in the book) and mentions that Bond is just starting out.
* Many movies adapted from Creator/StephenKing short stories, such the ''Franchise/ChildrenOfTheCorn'' series, would be good examples.
** One of the most notorious instances may be the 1992 film ''Film/TheLawnmowerMan''. While elements of the short story technically appear in how the title character dispatches one of his victims, the plot itself was so far removed from the source material that Stephen King sued to have his name removed from the title.
* Creator/PhilipKDick adaptations are prone to this.
** ''Film/TotalRecall1990'', which was an adaptation of Philip K. Dick's short story "We Can Remember It for You Wholesale". [[spoiler: The original story ended shortly after the hero returned to his apartment after visiting Recall, the film keeps going in a different direction from there on.]]
** ''Film/MinorityReport''. This one was particularly notable as it retained almost nothing of the original, except for the core premise and most of the characters.
%%** ''Film/{{Imposter}}''
%%** ''Film/{{Paycheck}}''
* ''Film/JohnnyMnemonic'' was adapted from a short story by William Gibson. Some added elements were taken from other Gibson stories set in the Sprawl, such as the "monk" assassin.
* Spielberg's previous work ([[AuthorExistenceFailure inherited after Stanley Kubrick's death]]) was also a short story adaptation, ''Film/AIArtificialIntelligence'', from Brian Aldiss' "Super-Toys Last All Summer Long".
* ''Film/ItsAWonderfulLife'' was adapted from a Christmas card's short story "The Greatest Gift". Three different screenwriters gave up trying to adapt it before Creator/FrankCapra got a hold of the rights. You'll notice that the better part of the film isn't even set at Christmas.
* ''Literature/AChristmasCarol'' has a lot of adaptations with a lot of expansion.
** One of the best is the famed Alastair Sim version, in which much more is added to Scrooge's past than was in the book, and as a result, a better job is done showing just ''how'' Scrooge came to be the miserly JerkAss everyone knows and hates.
** Some additional scenes are so common people tend to forget they aren't in the book, such as Tiny Tim and sometimes the other Cratchit children being introduced near the beginning, Bob's shopping for his family, the young Scrooge meeting Belle at Fezziwig's Christmas ball, Scrooge surprising Mrs. Dilber after his journey with the ghosts, and Scrooge going collecting from his overdue accounts.
** The Reginald Owen version delves a bit more into Scrooge's relationship with Bob Cratchit, as well as with his nephew Fred, although in exchange it omits some of the DarkerAndEdgier scenes, such as the breakup with Belle in the past and the looting and sale of the deceased Scrooge's possessions in the BadFuture.
** In the Alistair Sim and George Scott versions, Fan was Scrooge's ''older'' sister, and the backstory tells that Scrooge's mother died giving birth to him, and this is why his father sent him off to boarding school. The former also has a scene of Fan's own DeathByChildbirth.
*** The Sim Version has twice as many scenes as the standard Christmas past visits. In addition to Fan's death, we also get to see Scrooge and Marley help buy out Fezziwig's company, and then they buy the company themselves. The final visitations surround Marley's death. The Present and future visitations are condensed, however.
*** The Present visit actually does include an additional scene that shows Belle in the present day where she's doing charity work at a poorhouse.
** The Scott version is mostly faithful to the original story, including the often-omitted scene of Belle with her present-day family, but has a couple additional scenes, one at the London Exchange, where the charity solicitors meet Scrooge instead of at the counting house, another with Scrooge's father as he is leaving school, and a third where Christmas Present shows him a camp of homeless people, i.e. the "surplus population" mentioned earlier.
** The Creator/KelseyGrammer musical film featured Scrooge rejection of a loan for Mr. Fezziwig, and Marley's death on Christmas Eve.
* ''Film/BeingThere'' is largely faithful to the book, but finds a more natural conclusion by way of [[spoiler:Ben's death]]. In addition to adding little side-plots with minor characters like Louise the maid and the lawyers (making them more intriguing), and exploring the relationship between Chance and Ben more closely, it also adds a character, Dr. Allenby, who gives the story a climax when he [[spoiler:discovers Chance's true identity]].
* ''Film/TheChroniclesOfNarnia'':
** ''Film/TheLionTheWitchAndTheWardrobe'' has some Adaptation Expansion. We get to explore the backstory of the Pevensies, and a battle that took a couple of pages in the book is the main course of the film.
** ''Film/PrinceCaspian'' has even more expansion than ''The Lion, the Witch, and the Wardrobe''. Miraz gets developed into a Borgia/Medici style tyrant. It also adds the rivalry between Peter and Caspian, and Caspian getting PromotedToLoveInterest for Susan. And a summoning spell that got interrupted in the book goes further in the movie, bringing back the White Witch for one scene.
* The movie ''Film/{{Zoolander}}'' was based off of a series of shorts that were shown during the VH-1 Fashion Awards.
* ''Film/{{Carol}}'' makes it so that the POV is not just centered on Therese but on Carol as well.
* Every feature film adaptation of the works of Creator/EdgarAllanPoe and Creator/HPLovecraft.
** "The Pit and the Pendulum" has been made into a film several times - generally these adaptations use the actual scene where the main character gets trapped under a giant swinging blade slowly moving downwards for a climax, but have completely different plots that ultimately lead to the situation. ''Film/{{The Raven|2012}}'' (2012) also features an adaptation of "The Pit and the Pendulum" and adds a plot with a killer inspired by the works of Poe.
* ''Film/BrokebackMountain'' expands on the short story by going into more detail on the men's lives apart from each other, particularly Jack's relationship with his wife and her family, and Ennis's with his daughters.
* The two film adaptations of Creator/RoaldDahl's ''Literature/CharlieAndTheChocolateFactory'' are faithful to the novel's central plot but invoke this trope to make Charlie, a PinballProtagonist who basically gets a happy ending by doing nothing once he gets to the factory (and thus not getting eliminated by a disaster), more deserving of his triumph.
** In [[Film/WillyWonkaAndTheChocolateFactory the 1971 version]], Charlie and the other Golden Ticket finders are all approached by Willy Wonka's main rival, Mr. Slugworth (an AscendedExtra), with an offer for even greater riches than those promised by the tour if they'll bring him an Everlasting Gobstopper for him to duplicate. During the tour, Charlie and Grandpa Joe also disregard Mr. Wonka's warnings and sample the Fizzy Lifting Drinks, which almost gets them killed -- and turns out to negate Charlie getting ''any'' prize beyond the tour, a plot thread that ends up dovetailing with Mr. Slugworth's offer...
** The [[Film/CharlieAndTheChocolateFactory 2005 version]] is TruerToTheText in many details than the 1971 version (largely due to special effects advancements in the interim), but also has the most significant adaptation expansion of any version: A wholecloth {{Backstory}} for Willy Wonka, who is merely InexplicablyAwesome in the novel and all other adaptations, about [[DarkerAndEdgier his strained relationship with his dentist father]]. This results in a NotHisSled climax in which [[spoiler: Charlie initially turns down the chance to be Mr. Wonka's heir and, after some time passes, helps to reconcile him with his father, whereupon the happy ending commences]].
* ''Film/ThreeHundred'' is based on a short graphic novel, so it didn't need much expanding. Only Gorgo's plotline in Sparta was added. The graphic novel never returns to Sparta once Leonidas leaves. The relationship between the Captain and his Son is explored a bit more, as is the relationship between the Captain's son and Stellios. The scope of the battles has also been expanded since the movie features creatures and situations that were not present in the graphic novel.
* "3:10 to Yuma" was originally a short story of about ten pages, set almost entirely in a hotel room and on the walk to the train. The movie adaptations in [[Film/ThreeTenToYuma1957 1957]] and [[Film/ThreeTenToYuma2007 2007]] have both rather broadened the scope.
* Creator/ErnestHemingway's short story "The Killers" leaves a lot of questions unanswered. The 1946 FilmNoir adaptation sends an unlikely detective--an insurance adjuster--to Nick Adams' bar to find out the answers... so the film writers had to come up with some.
* ''Theatre/IdiotsDelight'' has a YouAllMeetInAnInn beginning in which Harry and Irene meet at a hotel in the Alps. Harry, an old vaudeville performer who is traveling with a troupe of dancing girls, speculates that Irene the supposed Russian countess is actually another vaudeville performer that he had a fling with in Omaha years ago. The 1939 film adaptation adds an entirely new first act that dramatizes that BackStory, including Harry and Irene’s meeting and one-night-stand in Omaha.
* The full-feature film of ''Film/{{Pixels}}'' expands on things like where the pixels came from (originally a digital "bomb" in a discarded CRT television) and adds motivations for why the pixellated characters are attacking, plus a number of heroes with the skills needed to fight back.
* The adaptation of Susan Orlean's narrative nonfiction book (itself expanded from article to book-length) ''The Orchid Thief'', which is ''Film/{{Adaptation}}''! It morphed from the true life tale of an orchid poacher in Florida, to twin brothers, car chases, murder, ExecutiveMeddling, Narration, every trope in the universe, AuthorAvatar, etc.
* ''Film/BicentennialMan''. Much to everyone's horror, it altered Asimov's reflection on the nature of what it is to be human into a TastesLikeDiabetes love story.
* F. Scott Fitzgerald's farcical short story ''Film/TheCuriousCaseOfBenjaminButton'' was adapted to a three-hour long epic romantic film. So much was added that much of the story's final act about Benjamin becoming a teenager and then a preteen was cut out.
* ''Film/WhereTheWildThingsAre'' is a particularly bizarre example. Practically necessary since the original story was ''10 sentences long.'' The story is still, on the surface, a very simple tale about a child running away and playing with imaginary monster friends. But thanks to some intentionally obvious symbolism, the interactions between the monsters tells the underlying story of Max being dragged through his parents' nasty divorce.
* ''Talk Radio'' began life as a monologue-heavy one-act play. The movie used the play as the basis of a RomanAClef BioPic about Alan Berg, the controversial Denver radio talk show host who was murdered by a white supremacist gang in 1984, with the play's protagonist, Barry Champlain, as a stand-in for Berg.
* ''Ugetsu'' is an example of a well-known adaptation that greatly expanded the material of the original ''Tales of Moonlight and Rain'', which was a collection of stories unrelated in all but theme. Two stories were spliced together, with a few references from the others, new content was added and an award winning movie was made.
* ''Film/OliveTheOtherReindeer'' was turned by [[WesternAnimation/TheSimpsons Matt Groening]] and Creator/DrewBarrymore from a tiny 20-page children's book into a 90-minute cartoon movie. That ''rocks''. They even preserved the drawing style of the book. You ''must'' watch this movie at Christmas.
* ''Film/PeterPan'', the 2003 film version put a lot of emphasis on Peter and Wendy's feelings for one another, making a whole side plot that had to be resolved, cuing a BittersweetEnding.
* ''Film/{{Slingblade}}'' was first a short film called [[http://www.youtube.com/watch?v=qyFD0JfiKfc "Some Folks Call It A Slingblade".]] Mm-hmm. The short story was reshot to serve as the first scene in the film.
* ''Film/TheScarletLetter'' film adaptation adds gore, Indian raids, and a whole first act to detail the sexual affair dealt with in the rest of the film.
* ''Film/StarTrekTheMotionPicture''. Adapted from a one-hour pilot that was never made, and it shows. Instead of relying on [[{{Filler}} adding extra scenes and dialogue]], they [[{{Filler}} extended the establishing shots and ship movement sequences]], possibly hoping that the audience would be too mesmerized by the special effects to get bored.
* ''Film/NightAtTheMuseum'' significantly expands on the cute tale from the original children's book, adding into it a complete adventure involving an ancient Egyptian tablet.
* The original play ''Film/GlengarryGlenRoss'' did not feature Blake or [[OneSceneWonder his scene]] at all. Most agree the story works a lot better with the added setup.
* ''Film/TheBox'' was originally a five-page short story called "Button, Button", written by Richard Matheson. It expanded under the hand of Richard Kelly.
* ''Film/TheSorcerersApprentice'', a live-action film, based on a short in the anthological animated musical film, ''Disney/{{Fantasia}}''. No Mickey, but the special effects department had a fun time doing their job. Oh and it managed to include a homage to the short. The short itself is based on Johann Wolfgang von Goethe's poem "Der Zauberlehrling" (= The Sorcerer's Apprentice).
* Contrary to what WordOfDante might tell you, ''Ride/TheHauntedMansion'' has no real backstory. [[Film/TheHauntedMansion The 2003 movie]] responded by [[AscendedFanon ascending some fanon]] and bringing in a few {{Canon Foreigner}}s.
* The TV-movie of Kurt Vonnegut's short story ''Literature/HarrisonBergeron'' is a truly extreme case. The story is a single five-page scene; the movie is 99 minutes long and ''doesn't have that scene in it''.
* At the time of writing the movie, the ''Franchise/SuperMarioBros'' series didn't have much story or defined personalities for the characters unless you counted the various cartoon series or somewhat obscure comics. Because of this, the writers of the ''Film/SuperMarioBros'' movie had to write the story from the angle of a prequel, exploring ''how'' the Mario Bros. became the '''Super''' Mario Bros. In the process Mario and Luigi were given an older brother/younger brother dynamic/conflict and Koopa was provided a motivation for needing the Princess.
* ''Film/WeirdScience'' was adapted from the 1950s [[WeirdScience comic book of the same name]], specifically the story "Made of the Future" in issue #5. The adaptation expanded upon and [[MagicalComputer modernised the premise]]. And given a "Creator/BratPack" flavour to boot.
* ''Film/{{Battleship}}'' is an adaptation of the game TabletopGame/{{Battleship}}, which has no plot. The enemy fleet is aliens (with peglike missiles among their weapons) who disable radar and envelop the fleet in a shield, establishing a game board of sorts.
* ''Film/HarryPotter'': Throughout the films, multiple scenes are added; sometimes they are building up on past material, sometimes they are inventing it on the fly for the film's continuity. One of the most prominent examples of the latter: the wonderfully cute and spontaneous dancing sequence between Harry and Hermione in the seventh film.
** ''Film/HarryPotterAndTheChamberOfSecrets'': The Quidditch scene. In [[Literature/HarryPotterAndTheChamberOfSecrets the book]], directly after Harry's arm is broken by the rogue bludger, he spots the Golden Snitch near Malfoy, dives for it and catches it, and that's the end of it. In the film, Harry spots it and chases after it, but Malfoy manages to keep up, turning it into a race - through a tight series of wooden beams at high speeds, at that - before the arm breaking and snitch catching occurs.
** Similarly, the Chamber of Secrets climax is given a big blockbuster treatment, with Harry dueling and evading the basilisk all over the chamber.
** The flying car scene too - whilst the journey is smooth save for being spotted in the book, the film features the car nearly getting hit by the train and Harry almost falls out.
** Hermione is shown popping up seemingly out of nowhere during lessons in ''HarryPotterAndThePrisonerOfAzkaban'', reflecting how she's using the Time Turner. In [[Literature/HarryPotterAndThePrisonerOfAzkaban the book]] Ron merely wondered how she was getting to all her classes and it wasn't explained until the climax.
** During ''Film/HarryPotterAndTheOrderOfThePhoenix'' Umbridge's inspection of the teachers is shown in a bit more detail in the film than the book, additionally showing her enforcing various rules around the school.
** In the book, the Ministry simply passes various decrees. In the film, each decree is nailed to the wall outside the Great Hall as Umbridge gradually seizes control of the school. This is also a set up for Umbridge's eventual HumiliationConga - where Fred and George cause them all to fall crashing around her.
** The breakout of Azkaban happens offscreen in the book ''Literature/HarryPotterAndTheOrderOfThePhoenix'' but we get to see it in the film.
** Another very nice bit of expansion is Slughorn's story about Francis in ''[[Film/HarryPotterAndTheHalfBloodPrince Half Blood Prince]]'', a fish Lily Evans made from him out of a lily petal as a student. He lost it 16 years ago, the very day Lily Potter was killed, a fact which makes Slughorn guilty enough to help Lily's son at the expense of his own security.
** Also in ''Film/HarryPotterAndTheDeathlyHallows'' the audience is shown Hermione modifying her parents memories while in [[Literature/HarryPotterAndTheDeathlyHallows the book]] Hermione only told us she wiped her parents' memories. Where Hermione lives in the books is never confirmed, just that her parents are rich, moreso than the middle class Dursley family. Hermione's home in this film is in Hampstead Garden, London. There is a Deleted Scene where Yaxley arrives at the Grangers' house to find it empty due to her parent's modified memories.
** We also get to see Ron and Hermione enter the [[spoiler: Chamber of Secrets]], showing a scene only referred to in the books.
** The fight between [[SupportingLeader Neville]] [[spoiler: and [[RightHandAttackDog Nagini]] ]]. In the [[Literature/HarryPotterAndTheDeathlyHallows book]], Neville [[spoiler: decapitates her without resistance from her in a moment of surprise, albeit [[IncendiaryExponent whilst on fire]]]]. In the film, he [[spoiler: decapitates her [[ThwartedCoupDeGrace mid-launch]] at a helpless Ron and Hermione]]. [[RuleOfCool Yes, also extremely satisfying]].
** The final fight between Harry and Voldemort. In the books, Harry appears from beneath his invisibility cloak in the midst of the battle to deliver a ShutUpHannibal to Voldemort, just before the Dark Lord [[spoiler: tosses a killing curse at him, which backfires horribly. ''Again'']]. In Deathly Hallows – Part 2, the fight sprawls the entire breadth of the castle, from Voldemort stalking him in the hallways, battling in the Astronomy Tower, and pulling a FreefallFight before landing in the courtyard, where they engage in a BeamOWar duel which Harry wins when his Expelliarmus reaches Voldy. And yes, it is just as [[RuleOfCool epic as it sounds]].
** Crossing between this trope and CompressedAdaptation, many of the "new" scenes are created to convey plot points from the books in a quicker fashion. For example, the [[Film/HarryPotterAndTheOrderOfThePhoenix fifth movie]] has a scene in which Luna shows the Thestrals to Harry. This never happened in the book, but the scene covers the exposition of three separate book scenes from [[Literature/HarryPotterAndTheOrderOfThePhoenix Order of the Phoenix]] (Luna telling Harry that she believes him, Hagrid showing Harry the Thestrals, and Luna telling Harry what happened to her mother).
** ''Film/FantasticBeastsAndWhereToFindThem'' is a series of ''five'' feature films is planned, all inspired by one 42-page Comic Relief tie-in, more pamphlet than novel, and with no plot. The book ''Fantastic Beasts'' purports to be an in-universe textbook; the films follow the life of its writer, Newt Scamander.
* ''Film/TheHobbit'' trilogy split a fairly short novel into three long feature films. Creator/PeterJackson and team got the majority of the extra material from the appendices of ''The Lord Of The Rings'' and other parts explaining what else was happening while Bilbo and the dwarves journeyed to the Lonely Mountain. Tolkien himself actually considered doing a revised and expanded version of the novel along similar lines that would serve as a more overt prequel to ''The Lord of the Rings'', but ultimately decided against it.
** The first film, ''Film/TheHobbitAnUnexpectedJourney'', provides an expanded role for Radagast, whose presence in all of Tolkien's writings is very minor and is only mentioned by name in The Hobbit.
** The second film, ''Film/TheHobbitTheDesolationOfSmaug'' greatly expands on Bilbo's time with Smaug, including Thorin and company making a valiant effort to take Smaug down while still within Erebor. It also develops Laketown into a CommieLand. On the other hand it adds several original characters, most notably [[ActionGirl Tauriel]], who is put into [[RomanticPlotTumor romantic subplots]] with both [[AdaptationalBadass Legolas (who is not mentioned in the novel)]] and Kili. There are also several named inhabitants of Lake Town with now bigger parts, and Bard the bowman is arguably split into two characters, Bard himself and Braga, the captain of the guard.
** The final film, ''Film/TheHobbitTheBattleOfTheFiveArmies'', actually ''shows'' the titular battle, whereas the book had Bilbo get knocked unconscious in the first few minutes and wake up three days later after the fighting was done. Original character Tauriel gets a prominent part and in the end Bolg is killed by Legolas (not in the book) instead of by Beorn.
** Azog the pale Orc Chieftan should be deceased during the time of the story due to being beheaded by Dáin Ironfoot at the Battle of Azanulbizar years earlier. The films change Azog's background and story involvement as TheDragon, having survived the battle and losing his arm instead.
** The Master of Laketown and Laketown counselor Alfrid Lickspittle are both unnamed minor characters in the book, but have several scenes in the film. Laketown and its residents are some of the embellishments given detail well beyond the descriptions from the book.
* ''Film/RearWindow'' took a short story titled, "It Had To Be Murder" and added a love interest for Jeffries, plus subplots about the other tennants.
* The Warren Ellis comic ''Comicbook/{{Red}}'' was originally a three-issue thriller about a retired CIA agent being lined up for assassination by a new administration that was horrified about what would happen if his track record was made public. The [[Film/{{Red}} movie adaptation]] made it a comedy and threw in a bunch of fellow retired agents - all with the blessing of Ellis, who admitted the actual miniseries "would maybe run forty minutes, if there were a musical number."
* ''Film/ManOfSteel'' spends more time delving into Kryptonian society, and explaining the sociopolitical and ecological situation before its destruction, than any film adaptation before it. The explanation behind Krypton's destruction is unique to this movie, as is the detail about the abandoned Kryptonian space program.
* ''Film/TheDeepBlueSea'' opens out a great deal from the source material. Writer-director Terence Davies fills in the main characters' back stories through flashback and dream sequences, and also expands the roles of minor characters like Mrs. Elliot the landlady. Rattigan's play focuses only on the aftermath of [[spoiler:Hester's suicide attempt]].
* In the ''ComicBook/MortadeloYFilemon'' movies, Filemón is given a mother in the first and Mortadelo a sister in the second and an aunt in the most recent CGI-animated film. The comic books are inconsistential (almost with no continuity) about their families, and only recently they were standarized.
* The infamous ''Film/{{Doom}}'' movie replaces the one-man army with a squad of marines, changes the demons into mutants, renames the BFG the "Bio-Force Gun" and generally tramples all over the intent of the original game's plot.
* ''Film/TheWolfman2010'':
** The 2010 version explores a very different side of the relationship between Lawrence and his father as well as the psychological aspects the [[Film/TheWolfMan1941 1941 version]] wanted to do intentionally.
** Gwen and Lawrence's romance gets a little more foundation than in the original, mostly because this time around Gwen doesn't exactly have a living fiancé. This also does away with the creepy stalker undertones that took hold of the beginning of their relationship in the original.
** The [[MysteriousAnimalSenses side effects]] of becoming a werewolf, such as [[GoodThingYouCanHeal fast healing]], [[SuperSenses more acute hearing]], and [[SuperStrength increased physical strength]] are shown.
** Aberline is a new character, added to serve as a sort of an AntiVillain.
** Sir John's butler, Singh, is a new character as well.
** Albeit [[WeHardlyKnewYe very briefly]], we actually get to ''see'' Lawrence's brother and mother, who only received a passing mention in the original.
** In the extended cut, a good chunk of pre-establishment about Lawrence's father and mother are left out.
* ''Film/XMenFilmSeries'':
** ''Film/XMenDaysOfFuturePast'': [[ComicBook/DaysOfFuturePast The original comic book]] is a story of just 2 short issues. There is a BadFuture, Kitty Pryde is sent back in time to warn the X-Men to prevent a political assassination, which is stopped, Kitty returns to the future, the end. In its original form, it would be short even for an episode of an animated series. ''Everything'' else in this movie which was not mentioned in that short premise is something new.
** ''Film/XMenApocalypse'': The main storyline of the movie is adapted from Louise Simonson's original Apocalypse arc in ''ComicBook/XFactor'' (Apocalypse's origin and philosophy is explained, he recruits his Horsemen, he fights the X-Men), but it also takes elements from several other comic book stories:
*** ''ComicBook/AgeOfApocalypse'': Apocalypse tries to [[spoiler:become the God-ruler of Earth]].
*** ''ComicBook/NewXMen'': Magneto wants to [[spoiler:take over the world, he uses his powers to destroy the bridges around Manhattan]].
*** Barry Windsor-Smith's original ''[[ComicBook/{{Wolverine}} Weapon X]]'' series: [[spoiler:Wolverine has been captured by the the authorities, they give him his adamantium claws and skeleton and control him through a psionic helmet, until he breaks free, kills his captors, and escapes.]]
*** ''ComicBook/TheDarkPhoenixSaga'': Jean Grey's [[spoiler:massive Phoenix powers concern Xavier and the other X-Men]], so Xavier has [[spoiler:put those powers under a telepathic lock]], but eventually [[spoiler:the lock gets opened and the Phoenix is unleashed]].
** ''Film/{{Logan}}'': Also mixes this with PragmaticAdaptation:
*** ''Comicbook/OldManLogan'': Much of the comic would have been impossible to adapt due to the distribution of film rights. Among the only things taken from the original book is following an aging Logan, who also has an aging companion from the past (Hawkeye in the book, Charles in the film).
*** ''Comicbook/InnocenceLost'': Substantial material is adapted from Comicbook/{{X 23}}'s origin story, with Transigen serving as an {{Expy}} for the Facility, while also introducing Zander Rice, and of course X-23 herself. Elements of her creation and training appear in an in-universe film Logan finds. This material is itself further expanded upon, with X-23 being not just Laura, but an entire ''group'' of mutant children with different powers from different donors. [[spoiler:Logan's death also nods towards the death of Sarah Kinney in the book, as he ultimately gives his life trying to help her escape her pursuers, and gets to share a final, poignant moment with his daughter, dying in her arms]].
*** [[spoiler:''Comicbook/DeathOfWolverine'': Logan dies. His thick beard and tuxedo early on is very similar to an outfit he wears in part of the comic miniseries, and like the series a major setting of the film is at the casino. Logan sacrificing his life to save mutants from experimentation also serves as a nod to the books.]]
* ''Film/TheHungerGames'':
** As with the [[Film/TheHungerGames previous]] [[Film/TheHungerGamesCatchingFire films]], in ''Film/TheHungerGamesMockingjayPart1'' there is a lot of expansion on [[Literature/TheHungerGames the book]].
*** President Snow has a few more scenes of his own, where he is joined by his staff of [[CanonForeigner Canon Foreigners]]: Antonius, his right hand man, and Egeria, his head of national information.
*** President Coin gets a few more scenes with Plutarch Heavensbee, which help with her characterization. She also receives a backstory: her husband and daughter died in the last epidemic.
*** The raid on the dam in District Five is turned into an extended scene, from a simple throwaway line in the book.
*** The rescue of Peeta is expanded upon in the movie, and while Katniss was sedated for most of it during the book, here she's very much following the situation.
*** Effie Trinket didn't show up until near the end of the book version, with the implication that she had been held prisoner and tortured. Here she's defected to 13 (albeit unwillingly) and essentially takes the place of Fulvia, Plutarch's assistant, along with Katniss's prep team.
** Again in ''Film/TheHungerGamesMockingjayPart2'' with President Snow. In the extra scenes he has, it is shown he's becoming more sick. Also, it is implied he orders [[spoiler:the attack of the mutts on Star Squad 451 when they are underground]].
* ''Film/IntoTheWoods'' features scenes that are implied in [[Theatre/IntoTheWoods the musical]] but not shown, such as Jack cutting down the beanstalk and killing the giant. WordOfGod confirms at one point there would have been scenes planned with Jack in the Sky Kingdom and Cinderella meeting her prince at the festival early in production.
* ''Film/{{Paddington}}'':
** We see a glimpse of Paddington's life in Darkest Peru, and why Aunt Lucy was no longer able to care for him.
** The Browns are also more fleshed out:
*** Mrs. Brown becomes a children books' illustrator and a CloudCuckooLander.
*** Mr. Brown becomes an OverprotectiveDad (played for laughs) and risk analyst.
*** Judy becomes your typical moody teenage daughter, with a knack with learning foreign languages.
*** Jonathan becomes your typical rambunctious child who likes to make cool models and hopes to become an astronaut.
*** Mrs. Bird becomes Scottish and really likes her whiskey.
* ''Film/LeftBehind2014'' focuses on the airplane trip to London when the Rapture takes place which is no more than the first few chapters in the first book of the ''Literature/LeftBehind'' series, but expands upon those chapters by turning it into an airline disaster that Rayford Steele and his crew barely survive. That being said, though, it leaves out any mention of Chaim Rosenzweig or the Russian all-out assault on Israel that was stopped by divine intervention which Buck Williams in the books was a personal witness of.
* The basic plot of ''Film/{{Cinderella 2015}}'' is the same as [[Disney/{{Cinderella}} the animated film's]], but more time is given to fleshing out the characters and the setting. The prologue focuses on Cinderella's childhood, the deaths of her parents, and other events leading up to her current life with the stepfamily. Her relationship with Prince Kit is also ''much'' more established here than in the original film. For one, the prince didn't even have a name in the original.
* ''Film/BeautyAndTheBeast2017'' also expands on the story from [[Disney/BeautyAndTheBeast the animated version]], fleshing out the characters in various fresh ways, explaining Belle's family backstory and how her mother died, giving the Beast a backstory of his own with a {{Freudian Excuse}}, adding further scenes in the village to highlight Belle's unconventionality and misfit status, as well as further scenes of her bonding with the Beast at the castle, filling in the {{Plot Hole}} of why the villagers don't know that the Beast is their kingdom's enchanted prince, and bringing Gaston's villainy {{Up To Eleven}} with an attempt to murder Maurice.
* ''Film/{{Shane}}'' is a 2-hour movie adapted from a [[Literature/{{Shane}} very short book]]. Most scenes from the novel got extended in some way and some completely new scenes were added.
* In a way, ''Film/{{Deadpool 2016}}'' regarding the leaked CG test that ultimately is adapted into a major action scene.
* Thanks to ''Literature/{{Allegiant}}'' being split into two films, its first part, ''Film/TheDivergentSeriesAllegiant'', allows for many instances of this.
** [[spoiler:An additional subplot concerns the "rescue" (actually more like putting more people into the Bureau) of a village's worth of people. It serves as the first indication to Four that David is not what he seems]].
** [[spoiler:A meeting with the council members at the city of Providence finally causes Tris to discover David's true intentions. She does not learn about his alignment until very far into the novel]].
** [[spoiler:The whole plot about the memory serum is actually moved to much earlier in the timeline. Because Nita's rebellion is adapted out, Four immediately goes to Chicago following the aforementioned village's rescue, and Tris gets to visit Chicago again (in the novel, she spends her entire time in the Bureau). The battle between the Allegiant and the factionless is thus expanded, not to mention furthering Evelyn's role (she's essentially relegated to the background until Four's visit in the novel, which happens much, much later). David also has a very direct role in the battle. How ''The Divergent Series: Ascendant'' is going to fill the rest of the book's events is yet to be seen, seeing that the only event left uncovered is Tris' death]].
* Creator/StevenSpielberg's ''Film/TheBFG'' lengthens the Creator/RoaldDahl by adding several subplots, such as [[spoiler:reveals about a boy the BFG had taken in before, Sophie getting returned to the orphanage and calling the BFG to come back]], and greater emphasis on the other giants bullying the BFG.
* ''Theatre/PerfectPie'': In the movie Francesca comes to sing for a charity event Patsy is holding, and stays for the weekend instead of just the day. This gives the movie time to put in multiple subplots that weren't in the play, including Marie and Patsy having been in church chorus, them having planned on competing in a musical competition, and Francesca meeting and reconciling with the date who abandoned her at the dance.
* ''Film/RogueOne'': A sentence and a half from the OpeningScroll of ''Film/ANewHope'' became a two-and-a-quarter hour long movie.
* ''Film/TowerOfTerror'': a MadeForTVMovie a test to see if film adaptations of rides would be be a hit amongst audiences. The story of the haunted hotel from the ride introduction is made theatrical.
%%* ''Film/MissionToMars'', which was a Disney ride, though the ride of that name closed many years before the movie was made.
%%* 2002 musical ''Film/TheCountryBears'', from a Disney ride.
* Half-blind children biting Judas's flesh mentioned by [[Literature/TheFourGospels Luke or Mark]], but Gibson thought it was important to include in ''Film/ThePassionOfTheChrist''. His other additions are less demonic, especially the flashback showing the Mother of God making fun of God the Son's wonky homemade table and Mary's memory of picking up the infant Jesus as she watches her son fall under the weight of his bloody cross.

* Film novelizations inevitably require more detail to fill out the format. You should be prepared for "extra" scenes and dialogue that were cut from the shooting script, as well as inner monologues that give the adapters the chance to show off their narration skills. (Remember that in literature, TalkingIsAFreeAction.)
* ''Literature/FlowersForAlgernon'' was initially an award-winning short story by Daniel Keyes. Later on, he adapted it into a full-length award-winning novel.
* ''Literature/HaloTheFlood'' is ''VideoGame/HaloCombatEvolved'' adapted into book form. It adds a lot of details which were not in the original game.
* ''VideoGame/{{Descent}}'' has been adapted into a trilogy of novels. The novels take the games' scant plot and turn it into several interlocking plotlines involving epic badass piloting, corporate politics made entertaining mainly by Dravis's upgrade from CorruptCorporateExecutive to full-fledged MagnificentBastard, and a rather comical look at the plot through the aliens' [[note]]([[TheyWastedAPerfectlyGoodPlot The games quietly forgot about the aliens.]])[[/note]] and robots' eyes/sensors.
* Donna [=VanLiere=]'s book "The Christmas Shoes" is a detailed story that evolved from New Song's song of the same name. The book added much more to the story than the man who helped the boy buy shoes on Christmas Eve, and became the first in a series of books that continued the stories of the man and boy.
* ''Literature/HowToTeachPhysicsToYourDog'' began its life as a [[http://crisper.livejournal.com/26562.html Rabbit Hole Day]] blog post.
* ''TabletopGame/MagicTheGathering'' novels include details not present in the games or contradicting the game rules, which may be ignored or overwritten by more recent material.
* ''Literature/{{Nightfall}}'' by Creator/IsaacAsimov is an interesting example of adaptation expansion within a single medium. It was originally one of the most mind-bending short stories of early science fiction. He and Creator/RobertSilverberg later adapted the same story into a full length novel (for purely commercial reasons, reputedly). Most agree that the novel's only notable virtue is containing the original, in edited form, as a chapter.
* Asimov's novella ''Bicentennial Man'' was expanded by Silverberg into ''The Positronic Man'', a full-length novel, which was later adapted into the film ''Film/BicentennialMan'', mentioned above.
* ''Literature/EndersGame'' by Creator/OrsonScottCard began its life as a short story before being expanded into a (much more famous) novel. Card never intended the short story to be anything more than that. His real desire was to write ''Literature/SpeakerForTheDead'', a book about how it's not always right to NeverSpeakIllOfTheDead. He had much of the storyline down but had trouble coming up with a convincing protagonist. A friend of his suggested using Ender from the short story. Card liked the idea but didn't want to spend a third of the book introducing him. His final decision was to expand the short story into a novel he always intended to be a prequel. While ''Speaker for the Dead'' is quite well-known in its own right, it will never be as popular as ''Ender's Game''.
* ''Wild Things'' by Dave Eggers is the novel adaptation of the film ''Film/WhereTheWildThingsAre'', which is itself an adaptation expansion of the original children's picture book.
* ''Literature/AgathaHAndTheAirshipCity'' and, more, ''Literature/AgathaHAndTheClockworkPrincess'' contain material not included in the Webcomic/GirlGenius comics.
* The [[Literature/DoctorWhoNovelisations novelisations]] of ''Series/DoctorWho'' television stories often expand upon them.
** Most famously, the novel of "[[Recap/DoctorWhoS25E1RemembranceOfTheDaleks Remembrance of the Daleks]]" provided details about the Special Weapons Dalek, as well as the triumvirate of Rassilon, Omega, and the Other. Many fans consider it the predecessor to the Literature/DoctorWhoNewAdventures.
** This happens especially in the case of scripts considered weak for not having a lot going on in them. For instance, the novelisation of "[[Recap/DoctorWhoS18E1TheLeisureHive The Leisure Hive]]" has a large section pastiching the ''Radio/TheHitchhikersGuideToTheGalaxy'' {{Cutaway Gag}}s, going into great detail about the customs of the ridiculous and genocidal ProudWarriorRace civilisations that had created the Hive - little of which has any bearing on the plot, but all of which is funny. "[[Recap/DoctorWhoS21E7TheTwinDilemma The Twin Dilemma]]" goes into detail about how regeneration works (some of which was well-written enough to be [[RecycledScript recycled]] for the Fourth Doctor-narrated audio reconstruction of "[[Recap/DoctorWhoS4E3ThePowerOfTheDaleks The Power of the Daleks]]"), and adds a {{squick}}ly [[BlackComedy amusing]] sequence about a BrainlessBeauty Time Lord who lost everything upon regenerating into a plain body, and his attempts to restore his status by repeatedly killing himself and regenerating [[BodyHorror get worse and worse]] - just to add a little colour. The novelisation of "[[Recap/DoctorWhoS2E7TheSpaceMuseum The Space Museum]]", a comedy story which was heavily edited to remove a lot of the jokes, was rewritten to put most of the jokes back in.
** "[[Recap/DoctorWhoS17E6Shada Shada]]" didn't even get made. The book adaptation heavily rejigged the script to remove problems that Creator/DouglasAdams (the original writer) had identified with it as well as some faulty plot logic and poor construction. It also took two characters who got little development and were gone from the plot in the TV story and [[HumanFocusedAdaptation used them as viewpoint characters]] for most of the book, particularly Chris, who gets to be the main character. Several sequences are expanded out beyond what the BBC budget could reasonably allow, like the bike chase scene (which in the book version features a cameo appearance from Music/StatusQuo) and the setting of Shada itself, and background detail is added to flesh out the VictimOfTheWeek and Chris's first night in the TARDIS.
** The ''Literature/DoctorWhoNewAdventures'' novel ''Shakedown'' is an interesting example. Buried in the middle of it is a novelisation of the BBV spin-off video ''Shakedown: Return of the Sonatarans'', which doesn't feature the Doctor at all.
** The first ninety pages of the Fourth Doctor novel ''The Drosten's Curse'' by A. L. Kennedy is her Time Trips novella "The Death Pit", which already ended with a suggestion that there was more going on for the Doctor to investigate.
* The novelization of ''Film/{{Flash Gordon|1980}}'' massively expands upon the characters, giving Flash a childhood with [[AbusiveParents an abusive father]] and Dale Arden a backstory in which her uncle (or another, unspecified older man) seduced and raped her, which was neatly tied in with Ming the Merciless's treatment of her.
* Literature/WarmBodies began as a short story titled ''I Am a Zombie Filled With Love'' before being extended into a full-length novel. The story is still posted on the author's blog [[http://www.burningbuilding.com/zombie.htm here]].
* Ward Moore's ''Literature/BringTheJubilee'' was first published as a novella and later expanded to a full novel.
* The original ''{{Mulan}}'' was [[http://www.yellowbridge.com/onlinelit/mulan.php a short ballad]] that summarizes the story of [[SweetPollyOliver a girl who went to war]] and [[LadyOfWar became a valiant soldier]], surprising her comrades when they visited her home and [[SamusIsAGirl discovered her true gender]]. Since the original is just a summary, a lot of details would need to be made up whenever the tale gets adapted to [[Disney/{{Mulan}} animation]], [[Film/MulanRiseOfAWarrior film]], opera, or TV.
* The books of ''Franchise/TheHitchhikersGuideToTheGalaxy'' add a number of scenes and whole plotlines that weren't in the radio plays. This is entirely by design though as Creator/DouglasAdams intended for all versions of the storyline to be significantly different in some way from each by addition or removal of plotlines, characters and scenes.
* The novelizations of the Doom series of video games starts out following the plot of the first two games fairly well, although they add a female marine for the hero to talk to. Then the third and fourth books continue to expand the series and take it to some truly bizarre places, like revealing that the demons are aliens involved in an endless war without another faction of aliens, none of whom can die, and throwing in some truly out-of-place nonsense about Mormons with stockpiles of guns and ammo for the apocalypse.
* Creator/BruceCoville has done this with three of his own short stories.
** Every book in his ''Bruce Coville's Book Of...'' anthology series begins with one of his own stories. The first of these, ''My Little Brother Is a Monster'' (published in 1993), was expanded and adapted into the full-length book ''Always October'' in 2012.
** The seventh through eleventh volumes (published in 1996 and 1997) began with the five-part SerialNovel ''The Monsters of Morley Manor'', which was expanded and modified into its own book of the same title, released in 2003.
** ''Clean As a Whistle'', first published in the 1994 anthology ''Oddly Enough'', has been expanded into a full-length novel, ''Diary of a Mad Brownie'', slated for release in 2015.
* Pretty much all retellings of fairytales have to do this, since most fairy tales in collections are between 2 and 10 pages. Shannon Hale's ''Goose Girl'' takes a five page story with only one named character and a few throw away lines about talking to wind and ends up with a 400 page novel and three sequels set in the same universe.
* The book Literature/ALittlePrincess was adapted three times by the author, first as a short story, then expanded into a play, then expanded again into a full novel.
* Hunter Steele's novel ''Lord Hamlet's Castle'' does this to ''Theatre/{{Hamlet}}'', chiefly by making it HotterAndSexier. For example, when Ophelia recounts how Hamlet visited her in her bedchamber, what she doesn't tell her father is that she and Hamlet had extremely explicit, rampant, steaming, highly physical sex... which is ''why'' his stockings were "down-gyved to his ankle".
* In the ''Franchise/{{Noob}}'' webseries and comics, ''[[FictionalVideoGame Horizon's]]'' NonPlayerCharacter cast and plot are only alluded to via {{Boss Battle}}s and quests done by the main characters while their adventure happen. In the novel versions, both the game's overall plot and the NonPlayerCharacter stories are expanded, to the point of being on almost equal standing whith stories of the players.
* ''Freedom's Landing'', the first novel of Creator/AnneMcCaffrey's ''Literature/{{Catteni}}'' series, is expanded from a short story called "The Thorns of Barevi". The novel starts much like the short story and follows its plot up to the point where TheyDo, but instead they ''don't'', and the plot goes off on a dramatic tangent. (Even in the novel they do eventually, at which point there's a version of the short story's final scene.)
* Likewise, ''The Rowan'', the first novel of ''Literature/TowerAndTheHive'', is an expanded version of her first published story, "The Lady in the Tower". ''Damia'', the second, expands on "The Lady in the Tower'''s sequel, "A Meeting of Minds".
* Another example of expansion within a medium: Creator/LewisCarroll expanded his short story "Bruno's Revenge" into the two-volume novel ''Literature/SylvieAndBruno'' - or rather, wrote the massive work around them, including a lengthy section where he met the title characters in their own world, prior to his first encounter with them in the real one.
* The ''Literature/KingdomHeartsII'' novel is both this and CompressedAdaptation at the same time. The book cuts out a lot of the visits to various Disney worlds and zooms in on the main plot first involving Roxa's story and later the machinations of Organization XII. While the second volume has yet to be released, it appears that the Beast's Castle, Land of Dragons, Disney Castle, Timeless River, Halloween Town/Christmas Town, Atlantica, Pride Lands and Winnie the Pooh storybook worlds have all been excised from the story. On the other hand, the story delves much deeper into some stuff not explored in the game, presenting many scenes involving Axel, Naminé, Mickey Mouse and Riku, including for the first time depicting the show in which Riku makes Mickey promise not to reveal to Sora and the others what happened to him.

[[folder:Live-Action TV]]
* ''Series/TheWorstWitch'' has gone through this several times over. The TV movie padded itself with sequences including a "scaring contest" and an early sequence with Punk Charlotte Rae, and the later series would pad the same adaptation by using the "Ethel's a pig" sequence as the basis for an episode (introducing a whole new character in Mr Blossom's nephew Charlie), while adding in a climactic chase through the school grounds. Bizarrely, it's otherwise managed to incorporate adaptations of the next three books as-is (although ''The Worst Witch Strikes Again'' was made into two separate episodes).\\
Many of the episodes in the first two series have new plots not taken from the books, or expanded from small references in the books (e.g the main plot of first episode "The Battle of the Broomsticks" is based around a line mentioning that Mildred's Broom got broken after she flew it into some bins on her first day). The third series is entirely new material, as at that time [[OvertookTheSeries the books only went up to the second year]]. Since then two books have come out covering Mildred's third year which are different to the third series.
* Anthology horror series like ''Series/TheTwilightZone'' often have episodes based on short stories which expand on the original stories considerably.
** And, in fact, the show itself got this treatment when some individual episodes were adapted into short graphic novels.
* ''The Story Of Tracy Beaker'', which had her ''repeatedly'' adopted by Cam/sent back to the Dumping Ground over the course of five seasons, along with lots of new material. (In the book, her adoption by Cam is the HappyEnding, and the later books in the series are about her living with Cam.)
* ''Series/PrettyGuardianSailorMoon'' adapted only the first arc of the manga, while adding in various new elements such as Sailor Luna, Zoicite's loyalty to Endymion, "Nephikichi", Darkury (in addition to Mamoru also turning evil), a teenage clone of Queen Beryl, and different CharacterDevelopment for many of the characters, particularly Sailor Venus.
* The original British version of ''Series/{{The Office|UK}}'' ran [[BritishBrevity 14 episodes]] and focuses on four main characters. The [[Series/TheOfficeUS American adaptation]] runs about 200 episodes and features a much larger cast.
* The ''Series/BeingHumanUS'' has far more episodes per season than the original, with more plots added alongside the original's. This happens often - the main reason British shows are remade rather than aired straight is that American television has more episodes per season. (Creator/{{Syfy}} seasons are short by American standards and ''Being Human'' has gone up from six to eight episodes per season, so it's no longer a ''huge'' example of this. With those other shows, we're talking a move from a 6-ep UK season to a 22-ep US one.)
* ''Series/GossipGirl'', based on an 11 (eventually 12 + spinoff) novel series by Cecily von Ziegesar, ended up airing for six seasons and more than 100 episodes on Creator/TheCW.
* ''Series/{{V 2009}}'': Originally a two-part miniseries, now turned into a full fledged series.
* ''Series/BuffyTheVampireSlayer'' was originally a movie, before becoming a seven-season TV series. Specifically, the show depicts what (supposedly) happened ''after'' the movie, when the Summers family moved from L.A. to a small California town.
** Then, the series spills over into a comic adaptation after concluding its TV run.
* Similar to the above, ''Series/{{Angel}}'', another Creator/JossWhedon work, has a BolivianArmyEnding, but it gets a comic expansion to help sort out the loose ends.
* [[Series/FaerieTaleTheatre Shelley Duvall's Faerie Tale Theatre]] expanded on the story of Goldilocks and the Three Bears.
* When ''Series/ShitMyDadSays'' was announced as an upcoming TV series, the Twitter feed it was based on had only 67 tweets. It's safe to say the show contains more words than that ''per episode''.
* Filipino CopShow ''Series/AngProbinsyano'' (lit. ''The Man from the Province'') shared very much the same premise as the 1997 Creator/FernandoPoeJr [[Film/AngProbinsyano film]], i.e. a twin brother assumes the role of his fallen cop sibling who was betrayed and killed by corrupt police officers in a drug sting operation, but further expanded and modernised the plot, often incorprating ComicRelief, SliceOfLife and real-world references to locally-occuring crimes and other such incidents into the mix.
* In ''Series/TheDeadZone'' TV series, the BigBad of the [[Literature/TheDeadZone book]] and movie is still around, but rather than being obsessed with him, our hero is too busy solving the MysteryOfTheWeek to worry much about TheEndOfTheWorldAsWeKnowIt.
* The first season of ''Series/MightyMorphinPowerRangers'' ended up trimming the 50 episodes of ''Series/KyoryuSentaiZyuranger'' that Saban picked up from Toei into 40 episodes, with the "Doomsday" two-parter [[SeriesFauxnale originally intended to be the finale]]. However, when the show proved to be a bigger success than expected, Saban had no choice but to contract Toei to shoot additional footage specifically for ''MMPR'', since they were not ready to adapt the ''Franchise/SuperSentai'' franchise's tradition of changing the team's costumes and robots every year. For the remaining twenty episodes of Season 1 and the first thirteen episodes of Season 2, ''MMPR'' used completely new action footage which featured the original ''Zyuranger'' costumes and robots with all new monsters that were not from any prior ''Sentai'' show.
** ''Series/TensouSentaiGoseiger'' had Mons Drake, who was only the first BigBad of three. However, his overseas counterpart in ''Series/PowerRangersMegaforce'', Admiral Malkor, was greatly expanded upon and instead serves as the overall BigBad of said adaptation.
* The ''PrettyLittleLiars'' TV series is doing this, adding plots for characters that weren't major in the book, and adding characters as love interests, probably because the book series only had 8 novels and most of the plot involved them trying to find A.
* ''Series/JeevesAndWooster'' added plenty of extra material to the [[Literature/JeevesAndWooster short stories]] being adapted, including events that Bertie wouldn't have seen (and therefore couldn't have narrated).
* While [=NBC=]'s ''Series/{{Hannibal}}'' draws on the entire Franchise/HannibalLecter franchise, is it most directly and specifically based on the novel ''Literature/RedDragon''. The series takes two and a half seasons to cover a handful of incidents briefly described in the novel's backstory -- the Minnesota Shrike killings, Will Graham's spending time in a sanitarium, and Hannibal Lecter's incarceration -- while ''majorly'' expanding on the relationship between Will Graham and Hannibal Lecter. The show only starts on the main story of ''Red Dragon'' (the Tooth Fairy killings) in the second half of season 3, and the added context changes the plot somewhat.
* ''{{Series/Les Revenants}}'', despite having fewer people coming back to life than the movie it's based on, has more time to develop both the plot and the characters.
* ''Series/{{Elementary}}'' expands Sherlock Holmes' addiction to an extremely relevant arc in the first season that is the premise of the show and changes Watson role from a mere foil/sidekick to {{Deuteragonist}}.
* ''Series/FromDuskTillDawn'' follows the plot of [[Film/FromDuskTillDawn the movie]] relatively faithfully, but at a much slower pace. At the same time it adds new characters and provides a backstory absent from the original film.
* ''Series/{{Haven}}'' is based on one of Stephen King's shorter literary works, ''The Colorado Kid''.
* ''Series/OnceUponATime'' is this to a large number of fairy tales and classic stories, including most things that Disney has adapted (but some that they haven't, like ''Literature/{{Rumpelstiltskin}}''). The basic thrust of the series is that, rather than being the events of stand alone stories, all of these things happened as part of a single large story. As an example, the story of Rumpelstiltskin's encounter with the miller's daughter is closely tied to the story of Snow White and the Evil Queen. Rumpelstiltskin also figures prominently in the stories of ''Literature/PeterPan'', ''Disney/{{Frozen}}'' (and [[Literature/TheSnowQueen the fairy tale from which it was adapted]]), and ''Literature/TheWonderfulWizardOfOz'', among others.
* ''Series/AgentsOfSHIELD'' does this for [[spoiler: Skye/Daisy Johnson/Quake]]. In the ''ComicBook/SecretWarriors'' comics, all that's ever really revealed about [[spoiler: Daisy]] is that she's the long lost daughter of Mister Hyde, and that she's the personal protege of ComicBook/NickFury. ''Agents of S.H.I.E.L.D.'' essentially provides a season and a half worth of background info, explaining her parentage in greater detail and exploring her life ''before'' [[spoiler: she was revealed to be one of ComicBook/TheInhumans]].
* ''Series/TwelveMonkeys'': Necessary, given the transition from a [[Film/TwelveMonkeys 2-hour feature film]] to a multi-season television season. The significant expansions include [[spoiler: a conspiracy surrounding the Army of the Twelve Monkeys and the assassin known as "Pallid Man", and the mysterious BigBad known as "The Witness"]], greater exploration of the post-apocalyptic future, and ''many'' more time-travel missions for Cole.
* ''Series/TheCasualVacancy'' expands upon Barry Fairbrother's interactions with other characters.
* The [[Series/HouseOfCardsUS American remake]] of ''Series/HouseOfCardsUK'' does this, in part because of the different political systems. In the original British version, it takes just four hours for Francis Urquhart to go from Chief Whip of the Conservative Party to being Prime Minister and ruler of his country. In the American version, it takes an entire season of thirteen 50-minute episodes (just shy of 11 hours) just to get Frank Underwood promoted from House Majority Whip to being tapped as the new Vice-President, and another thirteen to get him the rest of the way to the Presidency. Having an increased length is beneficial to the American version, considering that in real life, American politicians tend to rise more slowly than they do in Britain (in Britain, a leadership election can shift things in a fortnight; in the United States, there are no leadership elections. For the record, UsefulNotes/{{Barack Obama}}'s rise from Illinois State Senator to President in four ''years'' was considered positively meteoric).
* In the ''Series/MinorityReport2015'' series, Dash and Arthur are main characters shown as much as Agatha is, whereas in the movie the Precog twins were only briefly seen.
* ''Series/{{The 100}}'' TV series was never the most faithful adaptation, but what plot points it ''did'' take from the book [[OvertookTheSeries were covered within the first few episodes]], most of them just within the {{Pilot}}. Naturally, the show proceeded to create its own plots and characters from there on out.
* The Jeremy Brett ''Series/SherlockHolmes'' series extended short stories into hour episodes, either by including additional complications or by showing with more detail scenes that Watson only heard about second-hand. For example, the final episode, "The Adventure of the Cardboard Box", opens with the marriage of Mary and Jim, and includes a number of original scenes establishing the relationship between the three Cushing sisters, before Holmes gets involved (which he does earlier than in the story; Susan contacts him about Mary's disappearance before the eponymous box arrives). The brief reference to letting rooms to medical students until they became too rowdy becomes a scene of one medical student whose reason for being evicted ties back to the nature of the family. It also adds a subplot about grave robbing, and sets the events at Christmas to include scenes of Holmes and Watson celebrating both at home and with the police. While the story ends with the murderer's confession, the episode includes scenes of him in prison and Holmes and the police finding the bodies.
* ''Series/{{Preacher 2016}}'' is quite an extreme example of this. It spends its entire 10 episode first season telling a story that the [[ComicBook/{{Preacher}} original comics]] told in ''the first issue''. They do this so that they can take the time to expand on and explore the core characters and mythology before moving onto the comics' main MythArc at the very end of the season and into the rest of the series.
* With the exception of Bob, Luc Besson's original ''Film/{{Nikita}}'' did not spend a lot of time with the organization that kidnapped and trained the title character. We briefly meet some of the people there--the director, a tech, a quartermaster, Amande the charm school instructor--but the film is not, in the end, concerned about them. The 1997 - 2001 ''Series/LaFemmeNikita'', in turn, expanded on all of these roles, making them into the series' regular cast.
* ''Series/{{Sherlock}}'' frequently makes feature length episodes out of short stories, sometimes by using them as a mere skeleton to hang a more complicated plot around, sometimes by creating a completely new story with a few of the same character names, and on at least two occasions ("A Scandal in Belgravia", "The Six Thatchers") by telling the original story in the first half, before saying "And ''then''..." as the halfway twist.
* ''Series/HoratioHornblower'' was first based on stories from ''Mr. Midshipman Hornblower''. Numerous one-off characters are expanded and continue to appear in the telefilms based on the subsequent books ''Lieutenant Hornblower'' and ''Hornblower and the Hotspur.'' The first series also welded together elements from several of the stories, while the third took a few mentions of Irish unrest and made it into the overarching plotline. But the most notable example has to be the character of Archie Kennedy, who appeared in just two ''Midshipman'' stories as nothing more than a lighthearted fellow who joked with Horatio during a dull watch. The cast and crew liked Jamie Bamber's performance so much that they brought him back and made him Horatio's best friend and confidant. The Forester estate eventually ordered them to write him out because his presence was changing Horatio's character too much from the source, and so William Bush[[note]]who first met Horatio in ''Lieutenant''[[/note]] can take his canonical role as Horatio's best friend. (Which they did, after a transition period in which they formed a PowerTrio and [[spoiler:they gave Kennedy a memorable HeroicSacrifice]].)
* ''Series/ThirteenReasonsWhy'' expands greatly on the novel. In the novel, Clay listens to the 13 tapes explaining Hannah's suicide in one night and has minimal interaction with the subjects of the tapes, with much of the story being flashbacks. The show expands this to weeks of him listening to the tapes. It also adds more depth to the subjects of the tapes as well as a subplot about them trying to stop Clay from releasing the information to the public and [[spoiler: Hannah's parents suing the school for neglecting to notice the bullying.]] The show also received a second season, which will be all original content (since the book's plot was wrapped up in the final episode of the first season).
* ''Series/TheHandmaidsTale'': The series fills in a lot of the details on events which were only mentioned by the book. Among them are what happened prior to the regime taking over, and Ofglen's fate after she's taken away. The series also looks at the pre-Gilead backstories of Offred, Luke, Commander Waterford and even Nick.
* ''Series/{{Insecure}}'' is based on the WebOriginal ''WebOriginal/MisadventuresOfAwkwardBlackGirl'', and Issa Rae created/stars in both. However, pretty much the only thing that remains exactly the same is the basic premise. Some elements remain similar, such as Issa being a TokenMinority at her job and being an amateur rapper (although in the TV series they're turned into {{imagine spot}}s for the most part). Additionally, in the web series, we learn almost no backstory of characters other than the lead (named J in the original) whereas the TV series spends a lot more time characterizing Issa's friends and love interests.

* In general, many bands will have at least one or two songs in their setlist be quite a bit longer than the studio version when played live. Jam bands do this as a matter of course, but usually there will be at least one song where a solo section is extended to give either the guitarist, another instrumentalist, or the whole band room to improvise.
* When Music/CountingCrows covered Music/JoniMitchell's "Big Yellow Taxi", they added a couple of verses, giving the song an environmental message that wasn't really present in the original.
* The Music/RedHotChiliPeppers cover of "Love Rollercoaster" adds a rap verse that was not in the original song.
* The third movements of Music/GustavMahler's second and third symphonies are greatly expanded instrumental versions of the Lieder "Des Antonius von Padua Fischpredigt" and "Ablösung im Sommer."
* Music/{{Yes}}'s cover of Music/SimonAndGarfunkel's "America"(originally recorded for a record company sampler and available on the remaster of ''Fragile''), due to having multiple extended instrumental passages, changed a 4-minute folk-pop song into a 10-minute progressive rock epic
* Nursery Rhyme ‘’Johny Johny Yes Papa’’: If you listen to the original song, this is all about a child sneaking into the kitchen to eats some sugar out of the jar. In this [[https://youtu.be/PeSqNnT2r50 YouTube video]], it has several variety of sweets and desserts than just only suger and also has AnAesop [[SomeAnvilsNeedToBeDropped about eating lots of snacks will make you sick after lying.]]

[[folder:Newspaper Comics]]
* The [[WesternAnimation/ClassicDisneyShorts Mickey Mouse]] newspaper strip started out with an adaptation of the first Mickey Mouse short produced, ''WesternAnimation/PlaneCrazy'', but after Minnie parachutes off the plane, Mickey runs into a storm and finds himself crash landed on an island filled with pirates, and the strip goes on from there...

* Creator/SternPinball's ''[[Pinball/BatmanStern Batman]]'' greatly expanded the role of Scarecrow, elevating him from a mere cameo in the film to a near-equal for the Joker.

* While it also had some AdaptationDistillation, the RadioDrama of ''VideoGame/FinalFantasyTacticsAdvance'' also has an Adaptation Expansion of the game, such has the appearance of Nono's airship and the event when Ritz, Mewt, and Doned's arrival in Ivalice is shown. Also, there are new character, whose name is "Moogle Knight" and "Madam Kiri".
* The {{Audio Adaptation}}s of ''ComicStrip/{{Alex}}'' and ''ClareInTheCommunity'' naturally have to create plots out of whole cloth, to convert a three panel gag strip into a half-hour sitcom.
* The ''Radio/StarWarsRadioDramas'' included several scenes that were either cut from [[Franchise/StarWars the films]] or entirely new.
** The ''Film/ANewHope'' play starts as early as a few ''months'' before the movie. We get Leia using the ''Tantive IV'' to smuggle medical supplies to Rebel forces on Ralltiir, learning about the Death Star plans and acquiring them from Rebels on Toprawa, and Luke watching the battle between ''Tantive IV'' and the ISD ''Devastator'' (a cut scene that had a couple frames from it shown in one of the ''Visual Dictionaries'' a decade and a half later).
** ''Film/TheEmpireStrikesBack'' showed the [[CurbStompBattle Battle of Derra IV]], which was alluded to in several later EU materials including the first four books of the ''ComicBook/XWingSeries''. We also got a conversation between Han and Luke after he got the storm shelter put up in the Hoth wastes. It also explained Lando faking punching Han when they first meet as Lando wanting to see if Han still had his old reflexes.
** ''Film/ReturnOfTheJedi'' included Luke constructing his new lightsaber. Being that it was performed after the current EU got into full swing, we also got a CallForward to ''Literature/TheThrawnTrilogy'' in the form of a conversation between C-3PO and an undercover Mara Jade.
* The radio adaptation of ''Series/TheTwilightZone'' followed the plots of the original television episodes, but also added in several new scenes due to each episode being about 10-15 minutes longer than the television stories they were adapting.
* The H. P. Lovecraft Historical Society's films:
** The [[http://www.cthulhulives.org/store/storeDetailPages/dart-IWP-cd.html adaptation]] of "Imprisoned with the Pharaohs" expands on the thirty-page short story by adding Bess Houdini and recurring character Nathaniel Ward as major players in the narrative, in addition to including Houdini's stage show and introducing a subplot about Houdini trying to buy a sarcophagus and mummy from a museum.
** The adaptation of "Literature/TheCallOfCthulhu" is framed as a police investigation, which [[spoiler:causes a significant change from the original story at the end]].
** ''Dagon: War of Worlds'' takes Lovecraft's original very short story "Literature/{{Dagon}}" and turns it into a full-blown, feature-length sequel to "Literature/TheShadowOverInnsmouth" in the style of Orson Welles's famous ''Radio/TheWarOfTheWorlds'' broadcast.
* The radio version ''Radio/NewDynamicEnglish'' has the original content from the software (such as the Harris Family) but there are also new characters and it supposedly takes place after the events of the software (Max quits being a businessman after missing his family, Kathy left her job for the newspaper in New York).
* During the original run of the BBC comedy ''Radio/TheMenFromTheMinistry'', episodes where restricted to 25-30 minutes so scripts where often cut, sometimes heavily. However, when Finland's public-broadcasting company YLE made a Finnish version, they had no such restrictions. This lead to episodes being anywhere from 25 to 48 minutes, often featuring material which was either partially or completely left out from the originals. [[note]]If one listens to the Finnish version and then listens to corresponding episode in the BBC run, they can notice sometimes set-ups for gags that have been cut, or lines of dialogue that where either punchlines or references to jokes that never happen.[[/note]]
* ''Radio/DrJekyllAndMrHyde'' expands upon the novella considerably while adding common tropes found in adaptations. In particular, Jekyll's childhood, glossed over in his confession in the novel, is focused on at the start of the series.

* Roleplay/DinoAttackRPG is a massive Adaptation Expansion of Toys/LEGODinoAttack. The original LEGO Dino Attack line had a [[ExcusePlot very simple plot]]: mutant dinosaurs are attacking the city, and four guys are trying to stop them. However, the Dino Attack RPG revealed that this has happened all over the world, bringing in other LEGO-themed locations and showing the impact that these events have had on them. The Dino Attack Team of the original theme consisted of four men, but the RPG has shown that it is actually much larger and there are women helping out. It's also explained what happened to the citizens of the various places that have been invaded (an issue completely ignored in the original line), and there is even some background as to why the heck all this is happening in the first place.

[[folder:Tabletop RPG]]
* ''[[TabletopGame/PokemonTabletopAdventures Pokemon Tabletop United]]'' is a fan-made RPG adaptation of the ''Franchise/{{Pokemon}}'' series, which seeks to further diversify Pokemon and improve weaker species, by adding many more abilities and special traits than in the handhelds.

* The stage versions of Disney's animated features can be up to an ''hour'' longer than their source material, almost entirely through adding new songs. Characters who did not sing in the movie get songs, sometimes more than one; characters who did sing... sing even more. For instance, Gaston bribing the asylum keeper in ''Disney/BeautyAndTheBeast''? That's the basis for a song. Eric dancing with Ariel in ''Disney/TheLittleMermaid''? ''That's'' the basis for a song. Many existing songs also have new lyrics added.
** The [[ScreenToStageAdaptation stage musical]] of ''Disney/{{Aladdin}}'' includes brand new songs alongside the previously {{Cut Song}}s "Why Me", "Proud of Your Boy", "Babkak, Omar, Aladdin, Kassim", and "High Adventure" -- ''and'' the formerly-deleted characters who sing the latter two.
** ''Disney/TheLittleMermaid'''s stage adaptation elaborates on Triton's and Ursula's backstories, especially in the revised production with the latter's new VillainSong "[[StartOfDarkness Daddy's Little Angel]]"; Eric's royal heritage, conflict of interests between exploring the seas and inheriting the throne, and obsession with Ariel following his rescue, the latter told in "Her Voice"; Ariel's relationship with her father and sisters; and her [[PinocchioSyndrome identity crisis]] as a mermaid, first touched on in her introductory number "The World Above". Alongside Eric's aforementioned "One Step Closer", the [[EnsembleDarkhorse Mersisters]] and [[TagalongKid Flounder]] get a [[ADayInTheLimelight Song in the Limelight]] titled "She's in Love" upon observing Ariel's lovesickness for Eric; and Scuttle and his fellow seagulls have the tapdance number [[PepTalkSong "Positoovity"]] as they coach Human!Ariel with [[HowDoIShotWeb walking on her new legs]].
* ''Two for the Seesaw'' had a [[MinimalistCast cast of two]] and required no more than two apartment settings on either side of a split stage. When it was adapted into the musical ''Seesaw'', half a dozen minor characters and many additional settings were added. The result was not a hit.
* Choreographer Jerome Robbins and composer Music/LeonardBernstein created a 20-minute ballet called ''Fancy Free'', and used it as the basis for their first Broadway musical, ''Theatre/OnTheTown''. The adaptation was loose enough that no music was recycled.
* Most of the second act of ''Theatre/TheNutcracker'' is original to Tchaikovsky.
* All of the Creator/GilbertAndSullivan works are expansions on short stories, poems, and other of W. S. Gilbert's writings. Of these, the poems ("The Bab Ballads") have also remained fairly popular, especially in Britain, but [[ScrewedByTheNetwork copyright claims by the magazines he published]] meant his only attempt to publish a collection of stories ended up getting pulled from the market.
* TheMusical of ''Vanities'' added a DistantFinale where the characters reunite in their home town in TheEighties, remedying the rather [[NoEnding anticlimactic]] ([[DownerEnding and rather unhappy]]) ending of the original. Also, in the off-Broadway production, the story is told from a HowWeGotHere point of view, rather than directly following the girls through the ages.
* ''Theatre/SweeneyToddTheDemonBarberOfFleetStreet'' follows the Christopher Bond version of the Demon Barber, giving him realistic motives instead of just being a one-dimensional bad guy.
* When Shakespeare turned Thomas Lodge's novella ''Rosalynde'' into the play ''Theatre/AsYouLikeIt'', he added several characters of his own (most notably Jaques, Touchstone and Audrey) and had them recur frequently as comedy relief.
* The [[AdaptationOverdosed various stage adaptations]] of ''{{Theatre/Chess}}'' all expand upon the ConceptAlbum. Some additions that are particularly notable:
** The original London production [[NoNameGiven gave the chess players names]], introduced characters like CIA agent Walter, and added songs like "Interview" and "The Soviet Machine."
** The original Broadway production added lots of dialogue scenes and songs like "How Many Women" and "Someone Else's Story."
** The original Swedish production gave a new song to Svetlana and recycled a cut melody to give to Molokov.
* The 2013 West End musical ''Theatre/CharlieAndTheChocolateFactory'' is faithful to the novel but finds its own way to make Charlie a more proactive protagonist (see Film above) by expanding on both his character and Willy Wonka's. Charlie becomes a CheerfulChild and budding inventor who is in absolute awe of Mr. Wonka and his creations in a way the other four Golden Ticket finders [[CreativeSterility are not]]. Mr. Wonka turns out to be a MadArtist as well as a MadScientist. Charlie not only has to stay out of trouble but [[spoiler: prove that he is a kindred creative spirit]] to find his happy ending. Finally, [[spoiler: it turns out that Mr. Wonka is secretly on Charlie's side all along]]. Several [[FlatCharacter supporting characters]] are rounded out as well, with Charlie's family and Mrs. Teavee becoming {{Ascended Extra}}s.
* The stage show of ''Jingle Bells, Batman Smells, P.S.: So Does May'' from the ''Literature/JunieBJones'' books includes material from ''Shipwrecked!'' presented in flashback form. It also includes a few other small additional scenes, such as a fantasy sequence of Junie B. imagining herself unwrapping and squeezing a giant a Squeez-a-Burp as her classmates and Mr. Scary cheer her on and Music/AlsoSprachZarathustra plays.
* ''Theatre/ShrekTheMusical'' uses an extra half-hour that the film doesn't have to elaborate on the backstories of Shrek, Fiona, and Farquaad, as well as give more focus to the Fairytale Creatures as characters (especially Pinocchio).
* ''Theatre/AnAmericanInParis'' considerably expands upon the plot of the film, particularly where Lise is concerned.
* The stage version of ''Theatre/{{Anastasia}}'' uses the extra time of a stage show to fill in aspects of plot and character. In particular, Dmitry and Vlad's pasts are more fully fleshed out, and the context of the Russian Revolution and its aftermath become integral to the plot, rather than incidental or glossed over.

[[folder:Theme Parks]]
* At Ride/UniversalStudios:
** ''Ride/TheCatInTheHat'' ride adds on a few scenes not in the book, mostly just expanding on Thing 1 and Thing 2's run through the house, such as a scene inside a closet that has a tornado of clothes.
** ''[[Ride/HarryPotterAndTheEscapeFromGringotts Harry Potter and the Escape from Gringotts]]'' expands upon the trio's break-in and escape from Gringotts in Film/HarryPotterAndTheDeathlyHallows, showing the involvement that Bill Weasley, the bank's security trolls, as well as Bellatrix and Voldemort played in the whole thing.

[[folder:Video Games]]
* The AdventureGame of ''VideoGame/IHaveNoMouthAndIMustScream'', which was written by the original author, Creator/HarlanEllison, gave each of the five protagonists extensive backstories. This included Nimdok, who in the short story, never even revealed his real name. (He still doesn't, incidentally.) The player also has the chance to improve on the DownerEnding of the original story by guiding the protagonists through specific tests set up by the evil computer.\\
During development, the game's designer asked Ellison why this evil AI would choose those five particular characters to torture. The question fired Ellison's imagination and thus the characters received more development in the game. Despite the fact that the game has its flaws and isn't perfect, this is a ''very'' good way to show that TropesAreNotBad.
* The backstory of the original ''VideoGame/FinalFantasyI'' is heavily expanded on to tie into the backstory of ''VideoGame/DissidiaFinalFantasy'', to the point that Dissidia almost gives more plot for the first game than the first game itself did.
* ''VideoGame/{{STALKER}}'' is a large, 20+ hour computer game loosely based around [[Film/{{Stalker}} the movie]] by the same name, a 163 minute minimalistic presentation emphasizing long takes and simple scenes, which was itself based around a short novel called ''Literature/RoadsidePicnic''. C-consciousness, the various factions, and the like exist to pad the story in the video game.
* ''VideoGame/FusionFall'' Legacy, being a reimaging of the original [=MMO=], expands upon it in many ways:
** The time travel accident that strands the player in the future was just another one of Dexter's experiments ruined by Dee Dee in the original. [[https://m.youtube.com/watch?v=Ff9nOqn6sIs The Legacy intro]] portrays it as a full blown public event.
** Several nanos are being added to the game.
* Video games based on movies, especially in recent years, will inevitably end up doing this if they don't want their game to be shorter than the movie. A good example is ''WesternAnimation/KungFuPanda'', which adds in a ton of levels involving fighting various factions that have randomly chosen to attack rather than, y'know, train.
** This tradition goes all the way back to the good ole days, where the hero from a movie (whether or not the movie is based on existing material) will usually have to fight a bunch of henchmen or even freakish oddities that not only didn't appear in the film, but would have no place in it. There are many examples with the ''Franchise/BackToTheFuture'' NES games probably being the most egregious.
* Games based on superheroes will often try to make the playing field more even, so a character possessing titanic strength in the comics will be just somewhat stronger than a regular guy (e.g. Superman and Batman) and some characters will be possessed of powers that just never existed in the comics, usually including attacks that clear the screen of all the bad guys.
* Games based on ''The Hobbit'' and ''The Lord of the Rings'' films carry over the likenesses of the characters established in the films, continuing to run with the additional details not found in the books.
* ''VideoGame/FistOfTheNorthStarKensRage'' featured new moves for every character so they'd have an expanded move list. All moves were created by the authors of the original manga, Burunson and Tetsu Hara, so this actually means that not only are said moves canon, they also show what many characters that didn't get a chance to really showcase themselves were capable off. This is especially welcome with the Nanto characters, like Shin and Souther. Also many events in the original manga extended (such as battles with major bosses like Heart) or had new scenarios added in (for example the battle with Zeed were only several pages in the manga and the entire gang was massacred in one location while Ken's Rage features a true raid where Zeed thugs were found in every corner looting and murder).
* ''Manga/MagicKnightRayearth'' game adaptations adds much new lore to the existing Mythos wherein the original manga was only 6 volumes with events jumping immediately to another. For example the Sega Saturn game adds in so many characters, new locations (including towns which strangely were absent from the source material), and many side stories thrown. The SNES games, while mostly sticking with the manga's plot, also adds new towns, expands upon the locations visited in the manga (adding new events, larger dungeons, etc) and most notably gives the Magic Knights many new spells that never existed in any other incarnation of the story.
* The majority of ''VideoGame/TheWarriors'' serves as a prequel to [[Film/TheWarriors the movie]], explaining the characters' backstories. The final missions have the players play through the events of the film, plus an extra epilogue.
* The UsefulNotes/SegaCD version of ''VisualNovel/{{Snatcher}}'' features an extended opening sequence that adapts the prologue comic from the manual, which depicts Gillian and Jaime's last conversation before Gillian begins his first night as a JUNKER agent. It also features an ending that reveals what happened to [[spoiler:Mika and Katrina before Gillian leaves to destroy the Snatchers' main base in Russia.]]
* The ''Turok'' franchise. In [[ComicBook/{{Turok}} the original comics]], a pair of Indians get stuck in a valley full of dinosaurs... and that's it. In [[VideoGame/{{Turok}} the video games]], "Turok" is a title given to the eldest child in the Fireseed family, assigned to protect the portal between Earth and another dimension where "time has no meaning". Tal'Set Fireseed (''Turok: Dinosaur Hunter''), Joshua Fireseed (''Turok 2: Seeds of Evil''), and Danielle/Joshua Fireseed (''Turok 3: Shadows of Oblivion'') take up the mantle and venture to the Lost Lands, stopping {{Omnicidal Maniac}}s from taking it over and hunting down the bio-mechanical dinosaurs, demons and aliens that have spilled through into our world. Read that over and look at how we got from "two Indians in prehistoric valley" to that video game plot.
* ''Film/TheGodfather: [[VideoGame/TheGodfather The Game]]'' expands on some parts the movie skims over. For example, in the movie, Bruno Tattaglia's whacking is given just an offhand mention. It gets expanded into a plotline mission in the game.
* ''VideoGame/SuperRobotWars'' occasionally does this, particularly characters who are SparedByTheAdaptation, be they heroic or villainous, such as [[spoiler:[[Anime/MobileFighterGGundam Master Asia]]]] in ''VideoGame/SuperRobotWarsReversal'', [[Anime/MobileSuitVictoryGundam Fonse Kagatie]] in ''VideoGame/ShinSuperRobotWars'', [[spoiler:[[Anime/TekkamanBlade Tekkaman Rapier]]]] and [[Anime/BrainPowerd Jonathan Glenn]] in ''VideoGame/SuperRobotWarsJudgment''.
** One of the more prominent examples is a manga for ''[[VideoGame/SuperRobotWarsAlpha Super Robot Wars Alpha Gaiden]]'', which involves TimeTravel. The story showcases what happens during the timespan between the first game and ''Alpha Gaiden'' (which is only referred in one or two lines in the game), some background on the [[EnfantTerrible Machinery]] [[CloningBlues Children]], expansions on battles and what exactly happened to the cast from ''Alpha'' that is left behind by those who are transported to the BadFuture.
** ''VideoGame/SuperRobotWarsOriginalGeneration'' will generally expand on the cast by giving them more detailed origins. In ''Alpha 2'', Ibis Douglas' past is hinted at, but never explained in detail. ''Original Generation 2'' showcases her beginnings as a rookie pilot who dreams of heading off into space and being chosen for Project Terrestrial Dream. Often, AdaptationDistillation is also in the works: while her story from ''Alpha 2'' is repeated in the ''Second Original Generation'', it's executed differently - Ibis does not accidentally kill her mentor in a freak training accident; [[spoiler:he dies [[BusCrash off-screen from illness]]]].
* The ''VideoGame/StarWarsBattlefront'' games add battles that were implied or logical extensions of the films, such as the theft of the Death Star plans and the liberation of Cloud City.
* ''Film/SpiderMan2'' is based upon the movie, but adds loads of characters and villains that would never have made it into the film due to time (e.g. Black Cat, Shocker, Rhino). [[TropesAreNotBad In this case]], fans liked it. The first installment did this as well, probably the most noteworthy was that the burglar who shot uncle Ben turned out the be the gang leader of a gang called the Skulls so you had to go and beat them up first before you could find out where the shooter was.
** The game of ''Film/SpiderMan3'' continues the tradition: as well as the New Goblin, Sandman and Venom from the movie, the game introduces villains such as Lizard, Kingpin, and Kraven.
* ''All'' of the VideoGame/{{Lego Adaptation Game}}s like to do this.
* In ''VideoGame/GoldenEye1997'', several levels take place in the nine-year gap between the opening sequence and the proper beginning of the film. This includes Bond visiting a nuclear silo (and seeing Ouromov) and visiting the incomplete Severnaya bunker. Later on, near the end of the game, Bond also pursues Alec Trevelyan through a series of flooded caverns as the villain runs towards the control centre antenna.
* In the N64 adaptation of ''VideoGame/TheWorldIsNotEnough'', there was a subway sequence with a bomb threat that was not featured in the film (set between the boat chase and "Cigar Girl"'s suicide), among other additions, such as getting a full chase level out of a scene that lasts ten seconds in the movie.
* Like the film, the video game of ''VideoGame/TheHauntedMansion'' had to build a brand new backstory for the mansion, including a backstory for [[ExpositionFairy Madame Leota]].
* In ''VideoGame/TheLordOfTheRingsOnline'' Turbine has been forced to do this in order to make an MMO out of Tolkien's work. More specifically it gives more back story to the events taking place outside of The Fellowship's journey. Most of these take place immediately before and during the events depicted in ''Literature/TheLordOfTheRings'', but they occasionally give flashbacks taking place well before.
** An SNES version of ''Lord of the Rings'' had lots of this as well, but done very poorly. First you had to assemble the party of four Hobbits (Pippin and Merrin ''separate''), and find old Gaffer's glasses in a cave west of the Shire, otherwise Samgee wouldn't join. Then several hours later, you had to find 12 talismans otherwise you couldn't get through some tombs that were never in the book...
* The console ports of ''VideoGame/ReturnToCastleWolfenstein'' have a prologue mission set in Egypt, not found in the PC version.
* The SNES port of ''VideoGame/PrinceOfPersia1'' added many new levels and traps, as well as {{boss battle}}s.
* The [=PS2=] version of ''VideoGame/SplinterCell'' has an additional mission at a nuclear power plant, to make up for the system's graphical limitations. This causes a minor plot hole in the other versions, which still act as though the mission happened, leaving players confused about some "missing Americium-239" Lambert freaks out over.
* ''Iron Tank'', the NES adaptation of Creator/{{SNK}}'s ''TNK III'', was greatly expanded from its arcade counterpart, with branching paths, bosses, new enemies and weapons, and plenty of {{Engrish}} dialogue ("Watch out, use radar, gigantic enemy objects up ahead!"). In fact, most NES adaptations of arcade games did this, making up for the severe technical shortcomings of the time with additional content. Sometimes they ended up being completely different from their predecessors, and sometimes even [[AdaptationDisplacement surpassed the original]] in gamers' memories (''VideoGame/BionicCommando'', ''VideoGame/NinjaGaiden'', and ''VideoGame/{{Rygar}}'' being prime examples of the latter).
* The ''VideoGame/{{Pitfall}}'' arcade game, strangely enough produced by Sega, featured enhanced versions of the overworld of the first ''Pitfall'' and the underworld of the second, and added MinecartMadness and TempleOfDoom stages. The Atari 800 computer version of ''Pitfall II'' was also expanded.
* Areas 4 and 8 in the SMS version of ''VideoGame/WonderBoy'' were exclusive to that version, and featured entirely new environments and enemies. The boss levels of each were set in BubblyClouds and featured tougher bosses that threw lightning and had different theme music than the rest. The sequel's SMS port also had an extra stage set in a GhostTown.
* The PCEngine CD version of ''VideoGame/{{Raiden}}'', in addition to the obligatory Redbook music, had two additional levels with their own music pieces. Much later, the UsefulNotes/XBox360 port of ''VideoGame/{{Raiden}} IV'' also had two exclusive stages, somewhat alleviating the short length of the original arcade game.
* Debatable with ''VideoGame/ParasiteEve''; it ''is'' an adaptation of a franchise that started out as a movie and a novel, but at the same time, acts more as a sequel/continuation of the original story where it happens in a new location, this time New York.
* ''realMyst'' adds a new Age to the original ''VideoGame/{{Myst}}'', plus additional backstory tying it into the wider story of Atrus's family and people.
* Creator/HudsonSoft's ''Challenger'' for the Famicom took most of the gameplay and the English title of ''VideoGame/StopTheExpress'' and made them the first stage of an otherwise original ActionAdventure game.
* The SNES port of ''VideoGame/SonicBlastMan'' is a standard BeatEmUp in which the bonus game in between levels is the actual arcade game, [[http://classaction.findlaw.com/recall/cpsc/files/1996apr/96112.html with a much lower chance of injuring yourself.]]
* ''VideoGame/Rockman4MinusInfinity'' is a RomHack of ''VideoGame/MegaMan4''. It still has the same plot as the original, but the levels have been expanded, there are new minibosses and the powers obtained from the Masters have changed.
* ''Anime/PuellaMagiMadokaMagica Portable'' is designed with multiple routes diverging from how the story originally unfolded. It also depicts [[spoiler:the Witch forms of Mami, Kyoko, and Homura]].
* Despite being based on three movies in total, ''VideoGame/TheMatrixPathONeo'' still manages to add in more material for the game. Examples include more detail going into Neo's training, Neo being trapped on a stray code resembling a subway and facing down a SWAT team right after the famous one-on-one fight with Agent Smith, and Neo rescuing more inhabitants of the Matrix in between the events of the first and second films.
** There is also a minor branching path in that you can choose to follow Morpheus' instructions to escape the agents by climbing outside of Neo's workplace building.
* The UsefulNotes/SegaGenesis version of ''VideoGame/{{Wardner}}'', titled ''Wardner no Mori SPECIAL'' in Japan, expands Stage 4 and divides it in half, and lengthens the final stage with a BossRush and several vertical shafts.
* The NES version of ''Film/{{Willow}}'' takes the basic plot of the film, adds new detail to existing locations, and adds a number of villages, items, monsters, dungeons, and characters, introducing the village of Dew, the Eagle Clan, the dragons Po and Matanda, and Kchil of the Nail Clan. Bavmorda is the messenger of the Spirit of the Skies, and Fin Raziel is the messenger of the Spirit of the Earth.
* The NES port of ''VideoGame/{{Contra}}'' expanded the fifth and final level of the UsefulNotes/ArcadeGame into a four-level sequence. Some of the previous levels were also lengthened. ''Super C'' was more drastic, replacing the arcade's fourth stage with four completely new levels, as well as changing the order of or replacing certain bosses.
* ''VideoGame/KingsQuestII'' was mainly a FantasyKitchenSink mishmash of unrelated elements, making the plot feel very much like an ExcusePlot. The FanRemake by AGD Interactive, on the other hand, added to Kolyma's lore and tied most of the characters and places together, such as making the witch Hagitha the BigBad of the game (though she still works under the GreaterScopeVillain of the remake trilogy, [[spoiler: The Father]],) and making Dracula [[spoiler: Count Caldaur, the ruler of Kolyma who mysteriously vanished years ago.]]
* ''VideoGame/DonkeyKong94'' is this to the original arcade game.
* Several ''Manga/{{Bleach}}'' games gave some characters all new powers to account for them not being actually introduced in the manga yet. This includes Kyoraku getting [[BlowYouAway wind powers]], Ukitake using [[MakingASplash water]] and [[ShockAndAwe electricity]], and Harribel shooting {{Sword Beam}}s of all shapes and sizes.
* ''VideoGame/NarutoShippudenUltimateNinjaStorm3'' massively expanded on several fights from the source material, such as the efforts to subdue the Nine-tails on Naruto's birthday, Kakashi's fight against [[spoiler: the seven swordsmen of the mist]] (which as mentioned above was also adapted to the anime) and the 5 Kage versus [[spoiler: Edo Madara]] fight, an OffscreenMomentOfAwesome that had yet to be shown period.
* ''VideoGame/LegoStarWars: The Force Awakens'' has extra content bridging ''Film/ReturnOfTheJedi'' to the new movie, filling in some details about what happened between the two films.
* ''[[VideoGame/MarvelFutureFight Marvel: Future Fight]]'' is more or less an adaptation of [[Comicbook/JonathanHickmansAvengers Jonathan Hickman's Avengers Saga]], but with content from the [[Franchise/MarvelCinematicUniverse Marvel Cinematic Universe]], while expanding out some of the alternate universes from the incursions and including significantly more comic characters.
* ''VideoGame/TotalWarWarhammer'':
** A couple of the game’s [[HeroUnit legendary lords]] (army generals and faction leaders representing specific characters), such as Helman Ghorst and Duke Alberic of Bordelaux, have only a couple paragraphs of description in the tabletop lore, but in the video game become much more developed characters, with their own unique items, abilities and quest battle chains.
** In order to make up for Bretonnia’s somewhat limited unit choice in the tabletop material, CA ended up flat-out inventing a number of units, such as footsquires, holy water trebuchets and hippogriff knights, to fill out its roster and make it more competitively viable.
** The Lizardmen get several new units, including Feral Cold Ones (a pack of Cold Ones, a type of raptor-like dinosaurs normally used by the Lizardmen as cavalry) and likewise "feral" variants of the other dinosaur mounts as one-model monster units, with the reasoning being that giving the Lizardmen more dinosaur units would make playing as them more fun. There is also a Bastiladon variant with a Revivification Crystal, included to give the Lizardmen more options for healing and buffing.
** Norsca. In the tabletop game, Norsca never had its own army book and had little presence outside of the background lore -- its only presence in the game proper were some units in the Warriors of Chaos army. In ''Total War: Warhammer'', it becomes a fully playable, independent faction separate from the Chaos Warriors, with its own separate gameplay mechanics and unit choices, many of which were created for the game.
* One of the more notable and well-received features in ''VideoGame/SPV3'', a [[GameMod Custom Campaign]] that serves as a re-imagining of the original ''VideoGame/HaloCombatEvolved'' campaign, is the addition of level extensions to the missions ''The Pillar of Autumn'', ''Halo'', ''Assault on the Control Room'', ''Two Betrayals'' and ''The Maw''. These extensions have revitalized many of the level layouts that dedicated fans have become familiar levels. Many fans have stated that because of how well these extensions flow with the existing level layouts, they could easily be mistaken as part of the original level design.
* ''Franchise/{{Pokemon}}'' remakes all tend to do this to some degree.
** [[VideoGame/PokemonRedAndBlue Fire Red and Leaf Green]] adds the Fame Checker, an item that stores various trivia about most important [=NPCs=], and a whole new area called the Sevii Islands, which includes a lot of the newer Pokémon and gives the player something to do in the postgame (which was almost nonexistent in the originals).
** [[VideoGame/PokemonGoldAndSilver Heart Gold and Soul Silver]] add scenes that expand on the Kimono Girls and the respective versions' mascot legendaries, introduce the Pokéathalon, restore certain areas like Viridian Forest back into "proper" areas, and include and slightly expand upon ''Crystal''[='=]s Suicune subplot.
** [[VideoGame/PokemonRubyAndSapphire Omega Ruby and Alpha Sapphire]] ''hugely'' expand upon Teams Magma and Aqua, giving them more distinct personalities when they were nearly identical in the originals. There's also more backstory given on the Abandoned Ship, and the postgame Delta Episode that expands a lot on the series' timeline and universe.
* ''VideoGame/FireEmblemGaiden''[='=]s remake, ''Echoes: Shadows of Valentia'', gives the vast majority of the original's characters far more presence, whether it be through more presence in the main game, base/village conversations, or the now-standard Support Conversations. There are also a few new characters, and Memory Prisms allow the player to view flashbacks expanding on various new and old characters' backstories.

* ''[[http://worldpeace.emilymarthasorensen.com To Prevent World Peace]]'' was originally intended as a short story about magical girl villains. It, er, blossomed out of control. At last count, the author planned for sixteen chapters and was thinking of creating other short stories around the same characters.
* ''Webcomic/KnightsOfBuenaVista'' adds extra scenes to ''{{Disney/Frozen}}'', such as a battle against pirates and Anna thwarting robbers on the street.
* ''Webcomic/FiveKidsAtFreddys'' expands on the story of the missing children incident hinted at in the original games. It is planned to follow all five kids trapped in the pizzeria, with the story stretched out over three days.
* ''Webcomic/{{Erstwhile}}'' adapts lesser-known stories by Creator/TheBrothersGrimm. Most just follow their version, with the occasional [[NamedByTheAdaptation name]] or exposition thrown in; "Literature/SnowWhiteAndRoseRed," however, adds two new scenes to set up the {{Official Couple}}s and ending better. (One where Snow White talks to the bear, and another when the girls go in town, see a poster about the missing prince and meet his brother.)

[[folder: Web Original]]
* The classic {{Creepypasta}} [[http://creepypasta.wikia.com/wiki/Genetic_Memory "Genetic Memory"]] is written as a theory esposed to the reader. The illustrated version contained in [[http://www.youtube.com/watch?v=9oIYHK0divY this]] video adds a frame story and [[spoiler:a TwistEnding.]]
* ''WebAnimation/FTLKestrelAdventures'' This whole series is based on a playthrough of the game. In episodes 18-21, the Kestrel ends up in Kaban the planet where the Rebellion was formed.

[[folder:Western Animation]]
* ''WesternAnimation/BatmanTheBraveAndTheBold'':
** "Night of The Batmen!" is based on issue #13 of the [[RecursiveAdaptation show's tie-in comic]]. The writers had to add a lot of padding to stretch the story out into a 22-minute TV episode.
** "The Super Batman of Planet X!" does this for the Batman of Zur-En-Arrh. In the comics, the only details revealed about him were that he was an alien scientist named Tlano who was inspired to become a superhero after observing Earth's Batman. The cartoon actually shows his personal life and gives him a love interest, supporting cast, and even an ArchEnemy.
* The cartoon adaptation of ''The Bear'' gives backstory as to how he ended up in the girl's town in the first place (followed a bird, got stuck on an ice flow and taken to a zoo by a cargo ship), along with sending him back to the Arctic at the end. It also gives him a reason for visiting the girl, to return the teddy bear she dropped. In the book, he just comes and goes from the house and there wasn't a sequence with a bear made out of stars.
* ''WesternAnimation/HowTheGrinchStoleChristmas''. If you read the original book, you'll notice that it lacks Seuss's whimsical naming conventions. According to legend, he wrote it on a dare that he ''not'' use his signature made-up words. In the cartoon, with the bet no longer an issue, entire verses are added with the names in full effect.
* The children's book ''Literature/TheLittleEngineThatCould'' has had it done twice; once as a 30-minute movie in 1991, then as a full-length CGI film in 2011, with an AllStarCast. The first was more true to the book than the second.
* Fox's ''WesternAnimation/PeterPanAndThePirates'' massively expanded on the mythos of ''Literature/PeterPan''. All the characters -- Peter, Wendy, John, Michael, all the Lost Boys, Tinker Bell, Jane, Hook and ''all'' his pirates, the mermaids, Big Chief Little Panther and Tiger Lily -- are all greatly fleshed out in terms of characterization, and all get a DayInTheLimelight at one time or another, as well as some extra characters who were made up just for the show, like Hook's brother Captain Patch, Tiger Lily's brother Hard-To-Hit, the fairies and their King and Queen, and many others.
* The whole point of ''WesternAnimation/StarWarsTheCloneWars''. So far, there's been an 2-D adaptation directed by Creator/GenndyTartakovsky, which reveals that General Grievous is prone to coughing and wheezing because [[spoiler: Mace Windu was forced to crumple his chestplates in and severely maimed his delicate lungs.]] This adaptation was followed up by ''WesternAnimation/StarWarsRebels'', expanding even deeper into the world of ''Star Wars.''
* While the [[WesternAnimation/TeenageMutantNinjaTurtles2003 second Teenage Mutant Ninja Turtles cartoon's]] adaptations of comic book stories are usually paced to correspond to their source material -- one issue will almost always translate into one episode -- two exceptions stand out. The first is the arc composed by the episodes "The Search for Splinter," "Turtles in Space," and "Secret Origins" multi-parters, which take five issues' worth of material and expands it into ten, while the second is its adaptation of "Sons of the Silent Age," which, after completing a mostly faithful adaptation of the comic book by the fifteen-minute mark, fills out the rest of the episode with a plot about preventing an uncared-for nuclear power plant from spilling radioactive material into the river which was the setting for the story.
* The original ''WesternAnimation/{{Thundercats}}'' cartoon had an open-ended conclusion that left us hanging on an epic battle between Lion-O and Mumm-Ra. However, Wildstorm made several faithful comics to profoundly extend and conclude the story -- with a few non-canon adventure comics thrown in for good measure.
* The classic [[Creator/RankinBassProductions Rankin/Bass]] Christmas specials based on preexisting songs and poems all feature this trope in spades:
** ''WesternAnimation/RudolphTheRedNosedReindeer'' expands the plot from "a reindeer is [[AllOfTheOtherReindeer bullied because of his shiny red nose,]] but then [[SavingChristmas saves Christmas]] by guiding Santa's sleigh" to "a reindeer is bullied because of his shiny red nose, runs away from home, teams up with Hermey the dentist-elf and Yukon Cornelius, visits the Island of Misfit Toys, faces the Abominable Snow Monster, and ''then'' saves Christmas by guiding Santa's sleigh."
** ''WesternAnimation/FrostyTheSnowman'' expands the story beyond "Frosty is brought to life by a magic hat, plays with the kids, and then [[ButNowIMustGo leaves]]" to include his special friendship with little girl Karen, their attempts to travel to the North Pole where Frosty will be safe from melting, the villainous magician Professor Hinkle who originally owned the magic hat and wants it back, Frosty's {{Disney Death}} when Hinkle locks him in a greenhouse to melt, and Santa Claus's saving the day in the end.
** The original song of ''WesternAnimation/TheLittleDrummerBoy'' just has a poor boy visiting the baby Jesus, having no gift to give him, playing his drum for him instead, and the baby smiling at him. All the other details found in the special (the boy's name being Aaron, his parents' murder and his resulting misanthropy, the details of how he arrives at the manger, all the other characters' roles, etc.) are new.
** The basic plot of the original ''WesternAnimation/TheYearWithoutASantaClaus'' poem is that Santa doesn't feel like delivering presents this year, the kids gets whiny about it, but one kid named Iggy Heppelwhite tells his classmates that Christmas is about giving, the kids take his word to heart and give presents to Santa, and that cheers him up and gets him to go on his annual trek. Rankin/Bass' version added in the subplots about people not caring about Christmas anymore, and Mrs. Claus sending elves Jingle and Jangle to look for Christmas cheer, and of course, [[EnsembleDarkhorse the Miser Brothers]]. In fact, Iggy [[AdaptationalNameChange Thistlewhite]] is the only character in the special who originates from the poem (besides the standard Santa characters, of course).
* Creator/TheBBC's Christmas adaptations of Julia Donaldson picture books do this, mostly adding extra scenes which emphasise plot points (the carnivores exchanging notes and realising they were tricked in ''The Gruffalo'') or character notes (establishing ''why'' all the animals would like to travel with the witch in ''Room on the Broom'', and that the cat isn't keen on the idea), while leaving the actual story as it is.
* The ''WesternAnimation/TootAndPuddle'' special ''I'll Be Home for Christmas'' is this of the original book, adding in a number of new subplots and other material to fill a 45 minute special.
* The original six ''WesternAnimation/{{Madeline}}'' specials are highly extended versions of the ''Madeline'' books. The subsequent cartoon series, which ended up running four seasons, took the expansion further with new, original stories.
* The ''ComicBook/ZipiYZape'' 2003 animated series introduced some of Zipi and Zape's classmates that were never seen in the comics, such as Invi, Evilina or Wanda.
* ''Series/TheSuperMarioBrosSuperShow'' and its [[WesternAnimation/TheAdventuresOfSuperMarioBrothers3 sister]] [[WesternAnimation/SuperMarioWorld cartoons]] had to take characters from the [[Franchise/{{Mario}} source material]] who really had nothing in the way of personality or development and write a show about them. Their characterization of Luigi being a LovableCoward is also largely considered by fans to be the inspiration for Luigi's personality in newer games as well.
* Tie-in ''WesternAnimation/SpacePOP'' books show how Geela took over, and mention that Tibbitt is a present from her late father. They also go into more detail about the princesses, Geela, Chamberlin, and their lives, as well as the episodes' content.
** The cartoon expands on Juno's reality TV experiences, as well as adding a scene after an interview where Geela tries to arrest the princesses and the crowd helps them escape.

* MerchandiseDriven works almost always are this. A cast and crew will, in a nutshell, be handed some toys and ''maybe'' a bit of a back story and told "advertise this". Other than that and some ExecutiveMeddling along the way they're basically free to do whatever they want with it.
* Works based on ''The Lord of the Rings'' add details not present in the books, including naming the unnamed [[http://tolkiengateway.net/wiki/Nazg%C3%BBl Nazgul]], adding [[http://lotr.wikia.com/wiki/Category:Non-canon_Locations new towns]], expanding the [[http://tolkiengateway.net/wiki/Middle_Earth world map]], adding new characters or adding detail to minor characters to the point of becoming new characters.
* [[http://lparchive.org/Grand-Theft-Auto-San-Andreas-(Screenshot)/ This Let's Play and illustrated novelization]] of ''VideoGame/GrandTheftAutoSanAndreas'', which was told from CJ's perspective, adds a huge lot of story details that wasn't in the original game (especially Sweet, [[ADayInTheLimelight he got one entire chapter explaining his backstory]]), adds a lot of new characters to explain some of the new story details, as well as giving explanation on some of the glaring plot holes that were present in the game's story.
