** For the film series as a whole ComicBook/{{Rogue}} is most certainly this as a character. Besides the BlessedWithSuck TouchOfDeath blues, white streak in her hair and southern accent she’s got pretty much nothing in common with her comic counterpart being not powerful at all, extremely mopey and almost entirely lacking any sort of spine. In the comics she was a FlyingBrick for most of her character history and generally gets into as many scrapes as Wolverine, here she doesn’t fight at all, being scared of violence and generally needs to be rescued or protected. Even her moniker “Rogue” in the comics she got for being a troublemaker in her youth, something she certainly isn’t here though “Unable to Kiss Girl” isn’t as snappy.

* ''Manhwa/{{Priest}}'' is a rather unique and strikingly drawn ''manwha'' combining ReligiousHorror, ZombieApocalypse and TheWestern, as BadassPreacher Ivan Isaacs treks across the American frontier battling a band of rebel angels. [[Film/{{Priest 2011}} The movie]]...is about a ''bunch'' of priests fighting vampires in the far future. About the only thing the two have in common is a main character with a cross on his forehead. The only people who are happy about this are the ones who've never read the comic. The director made this change as he didn't want people saying that he was copying his previous film ''Film/{{Legion}}''.

** The movie also introduces it's own version of Felicia Hardy, better known in the comics as ClassyCatBurglar and Spider-Man's [[RelationshipRevolvingDoor on-off love interest]] [[Characters/BlackCatMarvelComics Black Cat]]. This version however never really interacts with Peter, lacks any superpower or special skills and isn't a criminal at all. Instead, she's Harry Osborn's NumberTwo at [=OsCorp=], a role she never had in the comics. There actually were plans for Felicia to eventually take on the Black Cat-persona, but as the planned ''Amazing Spider-Man''-cinematic universe got cancelled, nothing came out of it.
* Calling ''Film/ArtemisFowl'' a "loose adaptation" of [[Literature/ArtemisFowl the first book]] is generous; the characters are completely different from their book versions, with one of the most egregious changes being Artemis's characteriation as a generic KidHero protagonist rather than a VillainProtagonist who gets deep character development.

* ''Film/{{Minotaur}}'' pushes this trope to its absolute limit: it's based on Theseus' tale in Greek mythology and it does share some common themes (the monster's conception, the Labyrinth, the demand of sacrifice and the princess helping our hero), but other than that, it doesn't share a lot in common with the source material, not even its names: for one, it doesn't have the same hero (he is named Theo instead of Theseus, and he is a sheep-herder rather than an Athenian prince), the titular monster is just a skinless, zombie-like bull rather than a man with a bull's head and he is worshiped as an idol by TheEmpire rather than being a divine punishment inflicted by Poseidon (which is nowhere to be seen or mentioned). Said empire is called Minos Empire instead of Crete, its ruler is Deucalion rather than Minos.

* ''Film/{{Snowpiercer}}'' is based off of a French graphic novel named ''Le Transperceneige''. Very, ''VERY'' loosely - the only thing it has in common are the setting and the name of the train it takes place on. [[SubvertedTrope Subverted]] in 2016 when Volume 3 of ''Snowpiercer'' adopted the film into canon, saying that it took place roughly concurrecntly with the second volume.

* ''Film/TurkeyShoot'': The remake in 2014 basically shared the name (not even that with international releases, where it's titled ''Elimation Game'') and concept of people being hunted for sport, and that's it.

** ''Film/AvengersAgeOfUltron'': The film has nothing in common with the [[Comicbook/AgeOfUltron comic book story of the same name]]. Aside from featuring Ultron as the BigBad, of course. They just went with the name because it [[RuleOfCool sounded cool]].

*** The female lead in ''Film/AntMan1'' is Hope Van Dyne, an obscure character from the [[Comicbook/MarvelComics2 MC2]] continuity. Aside from sharing the same name and parentage, the two have nothing in common. The comic version of Hope is an evil villain named the Red Queen, while the movie version is completely heroic, and actually becomes the MCU version of Comicbook/TheWasp.

** ''Film/SpiderManHomecoming'' has a few characters who bear little resemblance to their namesake. This is probably because ''Franchise/SpiderMan'' has been adapted so many times in recent years that [[Administrivia/TropesAreTools the writers felt a need to shake things up a little]].

*** Ned Leeds is really an {{Expy}} of Comicbook/MilesMorales' best friend Ganke, except now he's Peter's best friend instead. He also hooks up with Betty Brant for a bit, but that's where the similarities end.
*** The fact that [[spoiler:Michelle goes by "M.J."]] is clearly supposed to tie her to Comicbook/MaryJaneWatson, but the two have almost nothing else in common aside from both being {{Love Interest}}s to Peter.

* ''Film/MenInBlack'': The first five minutes of the first movie is a faithful reproduction of the first few pages of the first issue of the [[Comicbook/MenInBlack comic]]. After that, they have almost nothing in common.

* Creator/NeilGaiman used to tell a story about receiving a prospective script for a [[Comicbook/TheSandman Sandman]] movie. Near the beginning, he read a scene in which the title character is attacked by soldiers while declaring "[[PunyEarthlings Puny humans!]] Your weapons have no effect on Morpheus, the Lord of Dreams!" Gaiman then put the script down and refused to read another word.

*** Comicbook/{{Psylocke}} lacks a British accent, has no telepathy or psi-blades, is a villain rather than an X-Man, and doesn't display any martial arts or ninja skills. According to Penn, the character wasn't even referred to as Psylocke in the script, while actress Meiling Melançon has said there were discussions about having her character be Kwannon instead.

* ''Film/WhoFramedRogerRabbit'' changes a lot from the original book, [[Literature/WhoCensoredRogerRabbit including the title]]. The only things the two have in common are the basic set up (a classic FilmNoir story featuring humans and cartoons[[note]] And even then, in the film, animated characters replace comic strip characters.[[/note]]), the racism allegory, two lines, [[spoiler: TheReveal that the seemingly human antagonists are in fact toons]], and containing 4 characters who also go by the names of Eddie Valliant, Roger Rabbit, Jessica Rabbit, and Baby Herman. ''That's it''. It might be more fair to say that the film was ''inspired'' by the novel, rather than it trying to adapt the novel to film (though author Gary K. Wolf liked the movie treatment enough to based his sequel novels directly off of it).

''That's it''.

* {{Invoked|Trope}} in ''Film/JurassicPark'' by Ian Malcolm: "At some point, we will see some dinosaurs on this dinosaur tour, right?" ''Film/JurassicPark'' itself counts more as a PragmaticAdaptation (and a fine one at that). It condenses a few characters, cuts down on the chaos-theory technobabble, and is all in all a well-liked film. The sequel, ''Film/TheLostWorldJurassicPark'', on the other hand, bears very little resemblance to [[Literature/TheLostWorld1995 the book]]. Which is odd, since Creator/MichaelCrichton specifically wrote the second book to more closely resemble the first movie (revealing that [[RetCon Malcolm actually survived]] for instance).

** The best part is how, in the original story, the possible effects of the altered past are built up to be unspeakably disastrous during the course of the story. When the Time Safari does get back, however, everything is basically the same... [[spoiler:and then they notice the wonky spelling...]] The story's ending was apparently too subtle for Hollywood, so we got a city overgrown with jungle (it doesn't even [[ItMakesSenseInContext make sense in context]]) and [[EverythingTryingToKillYou crawling with killer baboon-things and sewer sharks]]. Oh, and there's also something about a catfish-man. [[WhatDoYouMeanItWasntMadeOnDrugs Of course]].

* ''Film/BloodAndChocolate2007'': Aside from sharing the title and main character names, and the fact it has a werewolf girl in a forbidden romance with a human boy, this film has very little to do with [[Literature/BloodAndChocolate the book]]; it's been pointed out that even the title [[ArtifactTitle doesn't make sense anymore]] because of how much they changed the film's ending. It would be easier to list what the two stories ''do'' share in common than what changes are made. To name some: the setting goes from Maryland, US to Bucharest, Romania, Vivian's backstory and the main source of conflict is heavily altered, Vivian and Aiden are now college-aged rather than high schoolers, Gabriel is now the BigBad, the film ends with [[spoiler:Vivian running away with Aiden]], which ''definitely'' didn't happen in the book.

* ''Xtro'' can perhaps be more charitably described as a ThematicSeries - neither ''Xtro II: The Second Encounter'' nor ''Xtro 3: Watch The Skies'' have anything to do with the original or each other beyond being sci-fi horror films involving aliens making contact with earth. All of the aforementioned movies have the same director - apparently he holds the rights to the title ''Xtro'' but nothing else, so legally he can attach the name to any movie he makes so long as it doesn't otherwise make direct reference to any elements of the first movie.

* ''Xtro'' can perhaps be more charitably described as a ThematicSeries - neither ''Xtro II: The Second Encounter'' nor ''Xtro 3: Watch The Skies'' have anything to do with the original or each other beyond being sci-fi horror films involving aliens. All of the aforementioned movies have the same director - apparently he owns the rights to the title of the first movie, but no other elements of it, so he can legally ''only' use the ''Xtro'' title for in name only sequels.

* ''Xtro'' can perhaps be more charitably described as a ThematicSeries - neither ''Xtro II: The Second Encounter'' nor ''Xtro 3: Watch The Skies'' have anything to do with the original or each other beyond being sci-fi horror films involving aliens. Apparently director Harry Bromley-Davenport legally holds rights to the name of the first ''Xtro'' but nothing else, meaning that he can make sequels so long as they don't have any connection to the story and characters of the original.

* The classic Creator/RayBradbury short story, ''Literature/ASoundOfThunder'' and [[Film/ASoundOfThunder the film of the same title]] both involve time travellers accidentally altering the past while hunting a dinosaur -- and that's literally '''it'''. The movie even kills the concept on which the book was based ''in the first five minutes''. That's like Marty getting run over by a semi before he can hit 88 MPH in the first ''Film/BackToTheFuture''.

** ''Film/CaptainMarvel'' has a good member of the Kree race who is the one who inadvertently gives Carol Danvers her powers called Mar-vell who then [[spoiler: dies tragically]]. That is about where the similarities with the comicbook Mar-vell ends. For one, comic Mar-vell was the original Captain Marvel with Carol Danvers being a side-character in his storyline. In the film, Carol is the main character, and Mar-vell is a character in her backstory. The comic version was male and appeared to be his 20s-30s, while in the film the character is played by sixty-year old actress ''Creator/AnnetteBening''. The comicbook Mar-vell was a fully-fledged superhero in his own right, while film Mar-vell has no powers at any point and never even wears the iconic costume (that distinction falls to the film's BigBad). Comic Mar-vell was something of a mentor figure to Carol, while flim Mar-vell's relationship was purely professional. While both versions are reponsibile for Carol Danvers receiving her special abilities, the manner in which it is done is completely different. Lastly the character [[spoiler: dies in a completely different manner,]] in a flashback set before the film's events start. [[note]]Ironically, there was a good female Kree character in comic Mar-vell's backstory named Una who [[spoiler: perishes in a similar manner to the Mar-vell of the film]].[[/note]]

** For the film series as a whole ComicBook/{{Rogue}} is most certainly this as a character. Besides the BlessedWithSuck TouchOfDeath blues, white streak in her hair and southern accent she’s got pretty much nothing in common with her comic counterpart being not powerful at all, extremely mopey and almost entirely lacking any sort of spine. In the comics she was a FlyingBrick for most of her character history and generally gets into as many scrapes as Wolverine, here she doesn’t fight at all, being scared of violence and generally needs to be rescued or protected.

** ''Film/{{Next}}'' is based on ''The Golden Man'', and differs greatly from its source material even for a movie based on a Philip K Dick story: Both share the general idea of the government trying to capture a main character who has the ability to foresee the immediate impact of anything he does before he does it. However, the setting, the main character's background, personality, and appearance, and ''what'' the government wants with him are all changed beyond recognition: In the original story, it was a post-apocalyptic future, the main character was a golden-skinned, non-sapient mutant, and the government was trying to wipe out all mutants with superhuman powers. On the other hand, the film takes place in the present, where the main character is a perfectly normal-looking, sapient human, and the government wants him to use his abilities to help them stop a nuclear threat. Reportedly, the original script was much more faithful to the source material before some drastic rewrites kicked in.

*** Much like ''Age of Ultron'', this film has nothing in common with the original ''[[Comicbook/CivilWar Civil War]]'' story, other than the title, and the basic premise of heroes fighting each other, with the teams being lead by Iron Man and Captain America, because they don't agree about whether they should comply with the government. [[spoiler:In fact, the climatic battles are only tangentally related to the Accords.]]

* ''Film/TheMask'': [[ComicBook/TheMask The original comic]] was more of a horror series involving the titular Mask turning people into AxCrazy murderers. The movie, then [[WesternAnimation/TheMask the animated series]] turned the character into a comical Super Hero, kept as the main character a guy who only lasts one issue in the comic, and used few elements from the comic. [[AdaptationDisplacement The show and the movie are actually better remembered than the comic]], and the cartoon was rather well-received.

** Despite being named for the shortened title of the first book, the movie is actually a sequel of sorts. The Red Queen shares only her title with the chess piece from ''Through the Looking Glass'' and is in every other respect based on the Queen of Hearts from ''Alice in Wonderland'', presumably so that the film could feature a "good" White Queen as well as an "evil" Red Queen - but there again, the White Queen, aside from the name, is also a pretty different character compared to the original. The book followed mostly episodic structure where Alice is going from one character to another, the movie, however, introduces epic scale conflict of TheChosenOne for Alice to defeat the Red Queen, who conquered Wonderland, imprisoning several characters, it is the structure of the classic Good vs. Evil story. The book did not have any visible conflicts of that scale whatsoever, where nearly all of the characters are merely insane rather than good or evil.
