->''"But we see our main innocent, and, of course, her dad too''
->''This is Cindy Lou Who, who is no more than two...welve, but we'll give 'em a little leeway."''
-->-- '''WebVideo/TheNostalgiaCritic''', in his review of the 2000 version of ''Film/HowTheGrinchStoleChristmas''

In the process of adapting a work, many things don't translate very well into a different medium. An Age Lift is when the age of the character in question is changed or glossed over for the sake of the story. The idea is that the discrepancy between character and actor is much smaller, and in some cases, the exact age is not that important to the character. In some cases, this can simply be a case of the creators avoiding the embarrassing issue of a less than wholesome relationship, or wanting to give two characters more of a connection (not necessarily a friendly one; it can be used to emphasise a {{Foil}}) by making them contemporaries. Or maybe the creators just think the original age of the characters doesn't fit their target audience.

In live action, it can be a PragmaticAdaptation to take into account factors such as child labour laws and how demanding a role may be for a younger actor. It is also likely to occur if something happens to the character within the source material which makes keeping them at their original age problematic even with DawsonCasting, but, because the event in question is essential to the plot, leaving it out isn't an option either. The two most common forms of this appear to be aging pre-teen characters to teenagers so twenty-somethings can feasibly play them and aging thirty-something parents by about a decade to counter the potential ValuesDissonance relating to young parents.

Compare DawsonCasting, which leaves the age of the character the same but casts an older actor for the part anyway, and PlayingGertrude, HollywoodOld, and UnderAgeCasting, which do the same with younger actors. Also compare YoungerAndHipper. VagueAge is when the viewers [[ShrugOfGod and often the creators]] don't really know exactly how old a character is, and it's a great excuse for why the show might make a specific claim that seems like a [[{{Retcon}} change]] to some previously established fact.

ThreeMonthOldNewborn is a meta subtrope that results from the logistical issues of using actual newborns to play young babies.

!!Examples with their own subpages:

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

!!Other examples:

[[folder:Anime & Manga]]
* The English dubs to ''Franchise/{{Digimon}}'' went all over the place with this. [[Anime/DigimonAdventure The first series]] left the ages alone, but the second one, a TimeSkip sequel to the first, aged everyone up by a year, and ''[[Anime/DigimonTamers Tamers]]'', perhaps because it was DarkerAndEdgier, aged all the kids up by three years...which ended up creating some rather poor implications that ''weren't'' originally there, as at one point Ruki/Rika's mother's age is explicitly stated and this age is left unchanged, dropping the age difference between mother and daughter from 18 years to 15.
* The character of Nobue in ''Manga/StrawberryMarshmallow'' is aged up from sixteen years old in the manga to twenty in the anime. This isn't done to match a particular actor, but because Nobue is a habitual smoker and drinker and they couldn't show her doing that on TV if she was underage.
* The anime adaptation of ''Manga/AkuNoHana'' changes the characters from middle school students to high school kids, possibly due to the violent and psychosexual nature of the story, not to mention the animation is rotoscoped.
* ''Manga/Classi9'' has an interesting example, especially if considering the respective timelines of the real-life musicians. Haydn, who was born before all the other composers except for Bach, ended up being the youngest member of the cast. The rest is at least 16, but no older than 18, which makes Wagner roughly the same age as Liszt even though he married his daughter in real life. Beethoven is about as old as Mozart, even though in real life he was young enough to be his pupil. Bach remains the oldest and most responsible member of the cast, though.
* In the original ''Anime/CuteyHoney'' anime and manga, Honey and Natsuko are both high school students. In ''Anime/ReCutieHoney'' (as well as the live-action movie that inspired it), they're both young adults, with Honey working as a temp and Natsuko working as a police inspector.
* In the '60s animated ''Manga/{{Cyborg 009}}'' films (as well as the ensuing 1968 animated series), Cyborg 007 was changed from a middle-aged man to a young child. Reportedly, this is because the producers really wanted a KidAppealCharacter for the [[AudienceSurrogate audience to relate to]].
* ''Manga/SailorMoon'':
** Mamoru Chiba a.k.a. Tuxedo Mask in ''Manga/SailorMoon'' is 17 in the manga and 21 in the [[Anime/SailorMoon 1990s anime]]. This actually means the romance between he and Usagi - whose age is 14 in both - is toned down perhaps due to the larger age gap. In the anime Usagi and Mamoru's relationship comes across to some viewers like a college student allowing a teen girl who has a crush on him to say he's her boyfriend to keep her happy, whereas in the manga there is little doubt in the romance. ''Anime/SailorMoonCrystal'' has him at 16.
** In the 90s anime Chibiusa is the same age she seems to be physically. In the manga, however, she is Really700YearsOld, having been born when Usagi was in her early twenties but perpetually being stuck in a child's body.
** Had [[WesternAnimation/ToonMakersSailorMoon Toon Makers gotten the English rights to the series for their proposed live-action and animated adaptation]], Sailor Moon would've gone from 14 to 16, as mentioned in their theme song. The Creator/DiC dub kept her at 14.
* In the ''Webcomic/WonderMomo'' webcomic, Momoko's love interest Natsuhiko is clearly somewhere between 23 and 25. In the anime, he's changed into a high school contemporary of Momoko's. His personality also changes, going from cocksure adult to insecure teenager.
* The anime adaptation of ''Manga/SazaeSan'' lowered the age of most of the family. Sazae was 27 in the manga, now 24 in the anime.
* Zelda in the original ''VideoGame/TheLegendOfZeldaI'' is a young child roughly the same age as KidHero Link. Zelda in one of the [[Manga/TheLegendOfZeldaI manga based off said game]] is a teenager. [[spoiler:Link is also older than he should be, being Zelda's older half-brother, but [[OlderThanTheyLook looks younger]] than Zelda due to being part elf.]]
* In the ''Anime/StreetFighterIIV'' anime, Chun-Li is a 15-year-old martial arts student instead of an adult policewoman like she is in the [[Franchise/StreetFighter games]]. Ryu and Ken are also both younger than their game counterparts.
* ''Anime/{{Pokemon}}'':
** Red from ''VideoGame/PokemonRedAndBlue'' is eleven. Ash, Red's anime counterpart, was ten when he began his journey, [[NotAllowedToGrowUp and still is 21 years on]].
** Serena from ''VideoGame/PokemonXAndY'' has no official age but seems to be around 16 to 19, confirmed by the fact shes older than the canonically 16 [[spoiler:Emma]]. In the anime she's Ash's age (10). She's noticeably taller than Clemont in the games but is around the same height as him in the anime.
** Tate and Liza seem older in the anime than they did in ''VideoGame/PokemonRubyAndSapphire''.
** Lillie from ''VideoGame/PokemonSunAndMoon'' around 11 years old in-game, but she's noticeably taller than the protagonists and even her own older brother. In the anime, she's given a much softer and younger-looking appearance and is shorter than her brother, and around the same height as Ash.
* Misty is officially ten in the ''Anime/{{Pokemon}}'' anime but is twelve in ''Manga/TheElectricTaleOfPikachu''.
* The timeline of ''Manga/PokemonAdventures'' screws up the ages of the Pokedex Holders. The games are not in straight chronological order, but also contain multiple timeskips and even [[spoiler:{{Alternate Universe}}s]]. ''Adventures'' streamlined everything. For example, May and Brendan are either the same age or slightly older (their canon ages are 12 instead of 11 like Red, but Red had already began his adventure when the Hoenn games started) than Red and Blue. Ruby and Sapphire however are a good 6 years younger than the Kanto Pokedex holders.
* ''Anime/VariableGeo'': In the ''[[VideoGame/AdvancedVariableGeo Advanced V.G.]]'' series, Yuka and Satomi's official ages are 18 and 17 years old respectively. But, for reasons unknown, the OVA adaptation makes both of them a year younger.
* Komori from ''Manga/KomorisanCantDecline'' is 14 at the beginning of the manga. In the anime, she's 15.
* ''Manga/FullmetalAlchemist'':
** Pride, aka [[spoiler:Selim Bradley]], is the oldest homunculi. In [[Anime/FullmetalAlchemist the 2003 anime]] Envy is the oldest, as he [[spoiler:was the son of the BigBad Dante and the Elric's father Hohenheim CameBackWrong]] while [[spoiler:Selim]] is just a normal boy.
** The [[Film/FullmetalAlchemist live-action]] version has Ed and Winry around age 20, even older than they were in the final chapters of the manga.
* In ''Manga/{{Keijo}}'', Nozomi's age is 17 in the manga, but in the anime she's 18. This is because the anime skips a lot of the opening chapters of the manga and begins InMediasRes.
* Kai's age in ''Anime/{{Beyblade}}'' differs between the Japanese and English versions. In the English dub (and dubs based on it) he starts out as 14, is 15 in ''V-Force'', and is 16 in ''G-Rev''. In the Japanese version, Kai was 12, then 13, then 14.
* In ''Manga/TokyoMewMew'', Ichigo, Minto, and Retasu were all 13, Bu-Ling was 10, and Zakuro was 14. In the [=4Kids=] dub, ''Mew Mew Power'', [[DubNameChange "Zoe", "Corina", and "Bridget"]] became 16, "Kikki" became 14, and "Renee" became 17. Ichigo, Minto, and Retasu ended up becoming younger in the Tokyopop translation of the manga, going from 13 to 11 (though they would go back and forth switching between 11, 12, and 13).
* All over the place in ''Manga/MagicalGirlLyricalNanohaInnocent'', even without factoring in the artificial humans actual ages. For starters, Lindy and Precia are the same age, while Precia was old enough to be Lindy's mother in canon (literally, as Lindy was born the same year as Alicia). Alicia died at the age of five but she's instead depicted as a preteen. Teana and Subaru are both shown to be two years younger than Nanoha (in canon, they're three and four years younger than her respectively). Sette goes from being a [[BornAsAnAdult one year old adult]] to an elementary schooler.

[[folder:Comic Books]]
* Creator/DCComics ''ComicBook/EarthOne'' line sees two examples as in ''ComicBook/SupermanEarthOne'', ComicBook/JimmyOlsen is presented as being ''older'' than Franchise/{{Superman}} rather than younger. Conversely, ''ComicBook/BatmanEarthOne'' makes Lucius Fox ''younger'' than Batman as opposed to older (especially notable considering ''Film/TheDarkKnightTrilogy'' and, following the example made by it, ''WesternAnimation/TheBatman'' and ''Series/{{Gotham}}'' had Lucius as an old friend of Thomas Wayne before he and Martha were killed [[DeathByOriginStory on that fearful night]]).
* ''ComicBook/UltimateMarvel'' has seen this done:
** ''ComicBook/UltimateSpiderMan'':
*** The series placed Mary Jane Watson, Harry Osborn, and Gwen Stacy in high school with Peter when he's starting out his career was Franchise/SpiderMan, whereas the mainstream versions didn't meet Peter until college. The ''Film/SpiderManTrilogy'', ''WesternAnimation/TheSpectacularSpiderMan'', ''Film/TheAmazingSpiderManSeries'', the ''WesternAnimation/UltimateSpiderMan'' cartoon, ''ComicBook/SpiderManLovesMaryJane'', and ''WesternAnimation/MarvelsSpiderMan'' have followed its lead to varying degree, either removing one for later[[note]]with the original film trilogy having Peter and MJ meeting Gwen in college; the ''Amazing'' films having Gwen in high school, Peter reunite with Harry (and in deleted scenes meet MJ) in the summer before college[[/note]] or adding more to be classmates[[note]]''Loves Mary Jane'' making pre-ComicBook/BlackCat Felicia Hardy a transfer student with them; ''Spectacular'' likewise having Glory Grant and Randy Robertson go to school with him and pre-ComicBook/{{Venom}} Eddie Brock as a recent graduate; the ''Ultimate'' cartoon making many of Spidey's allies like Luke Cage and Iron Fist and enemies like Rhino his age; and the 2017 cartoon giving {{Age Lift}}s to ComicBook/AnyaCorazon, ComicBook/MilesMorales, and the Shocker among others to make them Peter and Harry's age[[/note]].
*** ''Ultimate Spider-Man'' also does this to ComicBook/JessicaJones, making her a senior at Midtown. In the classic Marvel Universe, Jessica and Peter were in the same grade.
*** Aunt May here is much younger looking than she is in the original comics. This was likely done to avoid any questions about why Peter's mother would have a sister significantly older than her.
** ''ComicBook/UltimateFantasticFour'' makes ''all'' of the titular four teenagers, as opposed to just Johnny Storm being a teenager.
* ''ComicBook/HeroesReborn'' has two examples. In the tradtional Marvel Universe, Reed Richards is a middle-aged man and ComicBook/{{Ultron}} is the creator of the ComicBook/TheVision. In the ''HR'' reality, Reed is closer in age to Sue and The Vision actually came ''before'' Ultron, with [[ComicBook/AntMan Hank Pym]] taking Ultron's role as Vision's creator and Ultron himself being designed to replace Vision as Hank's assistant.
* ''ComicBook/SonicTheComic'':
** Amy's age is unstated, but she isn't treated like the eight-year-old she was when introduced in ''VideoGame/SonicTheHedgehogCD''.
** [[spoiler:Knuckles]] is Really700YearsOld instead of being an actual teenager.
** Sonic and Knuckles are implied to be at least eighteen in later arcs, as they can visit bars. In the games they are fifteen and sixteen (originally sixteen and fifteen until they were switched in ''VideoGame/SonicAdventure'') respectively.
* The Justice League generation in ''Comicbook/{{New 52}}'''s Earth Prime are "around 25" rather than "around 35". In ''ComicBook/DCRebirth'' this actually gets explained as someone having stolen a decade of their history. On ''Comicbook/Earth2'', the heroes have had been de-aged by ''several ''decades, dropping the UsefulNotes/WorldWarII connection.
* In the Post-Crisis ''ComicBook/{{Superman}}'' comics, Comicbook/LexLuthor goes from a contemporary of Clark (they grew up in Smallville together) to a contemporary of Perry White (about twenty years older).
* In pre-Crisis ''Franchise/{{Batman}}'' comics, Lucius Fox's daughter Tiffany appears in one story, where she's an adult running the Wayne Foundation's anti-drugs program. She appears in much the same role in the post-Crisis ''Comicbook/RedRobin'', where she's the older sister of one of Tim's love interests, the teenage Tam Fox. In ''Comicbook/TheNew52'', she's a precocious pre-teen, the BrattyHalfPint younger sister of ''Batwing'''s Luke Fox.
* A few examples pop up in ''Comicbook/DCComicsBombshells''. Notably, Comicbook/LoisLane is reimagined as a 17-year-old newspaper hawker, which removes any potential squickiness when she begins dating Comicbook/{{Supergirl}} in the follow-up.
* ''ComicBook/ArchieComicsSonicTheHedgehog'':
** Tails in the games is eight years old. He is ten in the comics, in order to match his age in ''WesternAnimation/SonicSatAM''. Despite him being ''older'' than his game counterpart, in early issues Tails wasn't allowed to do much Freedom Fighting due to his young age.
** Amy's classic design from ''VideoGame/SonicCD'' is eight however for ''VideoGame/SonicAdventure'' she was {{retcon}}ned as twelve. Amy in the comics was initially ten, not eight. Her body itself was aged up to fifteen in order to match her game redesign (making her a preteen in a teenage body).
* ComicBook/{{Supergirl}} was originally born on a section of Krypton that survived the extinction, making her an actual teenager. Her more well-known Post-Crisis origin however had her as Superman's cousin who spent a longer time in space then him. She's chronologically much OlderThanTheyLook but was stunted into staying a teenager.
* ComicBook/BlackCanary was originally several years older than her love interest ComicBook/GreenArrow. Post-Crisis their ages ended up essentially swapped. This creates some inconsistency with Black Canary though. For example, she's supposed to have a maternal relationship with Speedy however that's hard to establish anymore as they're almost the same age.
* The original ComicBook/{{Batgirl}}, Barbara Gordon, was in her late teens or early twenties when Dick Grayson was in his early-to-mid teens. Post-Crisis however they established her as about the same age as him and Post-Flashpoint she seems to be ''younger''.
* ''ComicBook/BatmanYearOne'' established Jim Gordon as younger than his was previously depicted. This resulted in his daughter Babara Gordon, the original Batgirl, becoming his niece for a while.
* ''ComicBook/SpiderMen II'' revealed that 616!ComicBook/MilesMorales [[AdaptationalVillainy was an ally to]] ComicBook/TheKingpin around the time Fisk took over Rigoletto's operations, making him an adult when Peter was a teenager just starting out.

[[folder:Fan Works]]
* ''Fanfic/AdviceAndTrust'': The writer bumped the main characters age by a year (stretching the Angels' attacks timeline so that over one year has passed since Sachiel and Shinji came to town) so that he does not "feel quite as awkward having them going at it hammer-and-tongs nightly")
* ''Manga/{{Evangelion 303}}'': Shinji, Asuka, Rei, Kaworu, and Mari are 18 or older as opposed to 14. This also affects their characterization too, and is how the story differentiates from its source material. They drink, drive, have sex lives (or develop one), and are generally more worldly and independent than their teen counterparts.
* Happens frequently in fanfiction, when teenage characters are made old enough to legally consent to have sex with each other (or the writer's OriginalCharacter), or do other things that 15/16 year-olds couldn't conceivably do. Sometimes the excuse is that it's five years later.
* ''Fanfic/ChildOfTheStorm'' and its sequels broadly keep the generations the same (i.e. those people who are contemporaries in canon broadly remain contemporaries), but play around with character's ages relative to main character Harry Potter/Thorson, who's 13 and a half when the story starts - for instance, Carol Danvers, eventual {{Deuteragonist}}, who first appears in the comics in her late 20s, makes her first appearance as 15 year old. By contrast Wanda Maximoff a.k.a. the Scarlet Witch, is Harry's godmother and thus is in her mid 40s (though thanks to the age slowing effects of practising magic, [[OlderThanTheyLook she looks about 30).]]
* In ''Fanfic/PokemonResetBloodlines'', Ash wakes up in the reset timeline to find that he's now 15 years old, because things couldn't be reset perfectly. A number of other characters have also aged up or down to varying degrees.
* ''[[https://www.fanfiction.net/s/11772125/1/Metroid-Kamen-Rider-Generations-Full-Series Metroid: Kamen Rider Generations]]'' has [[Series/KamenRiderGaim Micchy]] and [[Series/KamenRiderDrive Gou]] having their ages lifted up to match their respective Live-Action TV actor's ages - Mitsuzane becomes 20 years old just like his actor, Mahiro Takasugi, as opposed to 17/18. While Gou is 23 years old like his actor, Yuu Inaba as opposed to being 20.
* ''[[https://www.fanfiction.net/s/11725053/1/The-Bald-and-The-Esper The Bald and the Esper]]'' makes Tatsumaki 22, a full six years younger than she is in [[WebComic/OnePunchMan canon]]. Though she's also just starting out as a hero rather than being an established one.
* Some characters in ''Fanfic/NeonMetathesisEvangelion'' had their birthdays shifted around by the author - Asuka's, Touji's and Hikari's are an entire year earlier compared to canon, Kensuke's nearly an entire year earlier, Shinji's three months earlier. The reason is that by European/American counting, quite many characters (like Asuka) are actuall 13, not 14 in the show. The change of birthdays ensures that by the time the fic starts, everyone is already 14. The usual reasons apply.
* [[http://www.deviantart.com/art/Hit-Woman-684395631 Seen here,]] an artist's rendition of [[Film/KickAss Hit-Girl]] as an adult, from Website/DeviantArt.
* ''Fanfic/PokemonNovaAndAntica'': The author has raised the ages of the canon characters. Much of the main cast are adolescents or full-blown teenagers. For example, instead of 10, Ash is 14. This retroactively means the others grew up during their travels as well. Sounds like the writer wants to ignore first episode of the ''B&W'' seasons like the rest of us.
* Fanfic/MarvelInfinites: Franklin Richards has a VagueAge in the comics, often between five and eight. In this fic, he's around twelve-years-old.
* In ''Fanfic/NeitherABirdNorAPlaneItsDeku'', Izuku Midoriya is the same age he is in the canon manga. But since he's also Kal-El, he's drastically younger than many of the heroes that are Superman's contemporaries in DC Comics, with characters like ComicBook/{{Starfire}} and Franchise/TheFlash being decades older than him.
* ''FanFic/ToHellAndBackArrowverse'': The writer made a minor adjustment to the ages of the main protagonists; Oliver is now only two years older than Barry, who is two years older than Kara. The biggest change is Kal-El, who several decades younger than he is in canon due to being in the same ship as Kara and thus stuck in the Phantom Zone with her.

[[folder:Films -- Animation]]
* ''Franchise/DisneyAnimatedCanon'':
** Literature/SnowWhite is seven in the original story. In the Disney version she's twice her original age, being fourteen.
** Ronno in the ''Disney/{{Bambi II}}'' midquel film. In [[Literature/{{Bambi}} the novel]], Ronno is implied to be several years older than Bambi. In the film, he is the same age as Bambi. He appeared as a young buck in the first film as well. Bambi's father is also significantly younger than in the book as he's [[CompositeCharacter combined]] with the Great Old Prince of the Forest (who is unrelated to Bambi).
** Literature/{{Rapunzel}} is quite young in her original fairy tale, possibly fourteen to sixteen. ''Disney/{{Tangled}}'' states she is eighteen.
** The real UsefulNotes/{{Pocahontas}} was in her pre-teens when she met John Smith, her lover in the film. The [[{{Disney/Pocahontas}} Disney film]] ages her up to sixteen.
** Esmeralda from ''Literature/TheHunchbackOfNotreDame'' is a sixteen-year-old girl. The [[Disney/TheHunchbackOfNotreDame Disney adaptation]] never [[VagueAge specifies]] her age however she doesn't seem nearly that young.
** Gerda and Kai are children in ''Literature/TheSnowQueen'' while Anna and Kristoff from ''Disney/{{Frozen}}'' are eighteen and in their early twenties respectively. On the other side of the spectrum, the Snow Queen is a Really700YearsOld [[TheFairFolk Fair Folk]] while Elsa is a twenty-one year old human with [[AnIcePerson ice powers]]. Originally the film kept the original ages however Gerda and Kai were revamped and Elsa became Anna's older sister. There are two side-characters called "Gerda" and "Kai" as a MythologyGag however they're middle aged.
* Astro is thirteen in the 2009 ''WesternAnimation/AstroBoy'' film. In the ''Manga/AstroBoy'' manga he is drawn far younger and seems to be of elementary age.
* ''WesternAnimation/TheLEGONinjagoMovie'' sees Misako aged down to a more middle-aged appearance rather than the more 60+ appearance of ''WesternAnimation/{{Ninjago}}'', making it more believable that she's Lloyd's mother. Additionally, Lloyd himself seems to legitimately be high school aged rather than mystically aged-up to be a teenager as in the series proper.
* The title character in ''WesternAnimation/{{Anastasia}}'' is portrayed as eight years old when the Russian Revolution breaks out and eighteen throughout the bulk of the film. The real Anastasia was sixteen when the Revolution broke out, seventeen when she was killed, and if she had lived she would have been twenty-five in 1926, when most of the film takes place. The [[Theatre/{{Anastasia}} stage version]] lifts her back up to her historical age, though.
* ''WesternAnimation/LovingVincent'' has an example of this. In real life, Adeline Ravoux (the innkeeper's daughter) was 13 when Van Gogh died. In the film, she appears to be about the same age as Armand, who is 20.
* Contemporary material for ''Disney/TheLittleMermaid'' had Aquata (the one in blue) as the oldest of Triton's daughters. ''Disney/TheLittleMermaidIII'' changes the birthing order of everyone. Aquata is now the third oldest while Attina (the one in orange with the crown headdress) is the heir.
* When the Peter Parker of the ''ComicBook/UltimateMarvel'' universe died, he was 16. ''WesternAnimation/SpiderManIntoTheSpiderVerse'' sees its version of the Peter ComicBook/MilesMorales is replacing die around the age of 27.
* In the stage musical of ''Theatre/TheKingAndI'', Prince Chulalongkorn is a child, and the real Chulalongkorn was 9-15 during the six years the musical's action [[CompressedAdaptation compresses.]] In the very [[{{Disneyfication}} Disneyfied]] [[WesternAnimation/TheKingAndI animated adaptation]], he's portrayed as a young man in his late teens or early 20s. This is so he can serve as a CompositeCharacter, replacing the AdaptedOut character of Lun Tha as the ingenue Tuptim's forbidden love interest.
* Damian Wayne was introduced during ComicBook/GrantMorrisonsBatman run as a 10 year old. The Robin in ''WesternAnimation/BatmanUnlimitedMechVsMutants'' is Damian, but he's depicted as a teenager like the other Robins before him.

[[folder:Films -- Live-Action]]
* In the 2015 adaptation of Creator/CorneliaFunke's ''Ghosthunter'' series, the professional ghost hunter Hedwig, a grey-haired CoolOldLady is played by Anke Engelke, who was born in 1965. The character in the movie seems to be intended to look rather younger than the actor than the other way round.
* Ang Lee's 1995 adaptation of ''Film/SenseAndSensibility'' is full of this trope. Colonel Brandon, who was supposed to be 35 or 36, was played by 49-year-old Creator/AlanRickman. The 19-year-old Elinor Dashwood was played by 35-year-old Creator/EmmaThompson, and 17-year-old Marianne Dashwood was played by 20-year-old Creator/KateWinslet. However, the movie implies that the Dashwood sisters are in their late and early 20s, respectively and that Colonel Brandon is an older world-weary gent that we would associate with someone nearing 50. Lee and (scriptwriter) Creator/EmmaThompson made a conscious decision to age Elinor up to at least her mid-twenties, because they didn't think the audience would accept a 19-year-old worrying about [[OldMaid being left on the shelf]].
* Roberto Benigni playing the title role in ''Film/Pinocchio2002'', at the age of 50.
* In the BBC film versions of ''[[Literature/SallyLockhart The Ruby in the Smoke]]'' and ''The Shadow in the North'', actor Creator/MattSmith plays street kid Jim, who is 11 in the first book and 16 in the second, as a man in his late teens/early twenties. Which could cause problems if they ever get around to filming the fourth book, ''Literature/TheTinPrincess''.
* This probably has to do more with legal compliance than artistic reason, but no matter what actress is playing her, the character of ''Literature/{{Lolita}}'' always starts the movie at age 14 or 15 rather than 12, which she is at the beginning of the book.
* In the film version of ''Film/LogansRun'', the mandatory death age was increased to 30 (compared to the book's 21) for this reason. The book's notion that there's ''no'' age of sexual consent: as soon as a citizen leaves the creche, anything goes probably doesn't help.
* ''Film/InterviewWithTheVampire'':
** In the book, Claudia has the physical appearance of a five-year-old. In the movie, Claudia is played by Creator/KirstenDunst, who was twelve upon the movie's release. Aside from narrowing down the {{Squick}} factor, this avoids the practical impossibility of a five-year-old actress playing a believable adult character.
** In the same film, Armand, a cherubic seventeen-year-old in the book, is aged up to his mid thirties and played by Creator/AntonioBanderas, apparently to avoid the {{Squick}} inherent in having two of the main character's three pseudo-love-interests be underage.
* ''Series/{{Dune}}'': None of the actors who've played Paul, Leto II and Ghanima Atreides, or Feyd-Rautha Harkonnen have been under 20. Of course, since Paul and Feyd-Rautha were 15 during ''Dune'' itself and Leto II and Ghanima were ''8'' this is understandable. Generally, Paul and Feyd's ages are not mentioned in the adaptations, which makes this arguably a case of AllThereInTheManual and DawsonCasting, but for the Creator/SyFy version of ''Series/ChildrenOfDune'', Leto and Ghanima's ages were upped to around 18. The [[Film/{{Dune}} 1984 adaptation of Dune]] also has the four-year-old [[CreepyChild Alia]] played by the nine-year-old (at time of release) Alicia Witt.
* One of the biggest criticisms of the Film/JamesBond movie ''Film/AViewToAKill'' was that Creator/RogerMoore was still playing Bond at age 57 (he was 45 he was first cast as Bond in ''Film/LiveAndLetDie''). Creator/SeanConnery himself said "Bond should be played by an actor 35, 33 years old. I'm too old. Roger's too old, too!". Even when he was first cast, Moore violated the canon of Ian Fleming's novels, which established that Bond faced mandatory retirement at age 45 (meaning Pierce Brosnan was technically too old for the role for most of his time as Bond, too).
** Turned on its head in ''Film/{{Skyfall}}'' where one of the main themes of the movie is how Bond (played by the 44-year-old Daniel Craig) is getting too old to keep working in the field.
* Most of the main cast of ''Film/PercyJacksonAndTheOlympians'' was aged up from their preteens. Most notorious in Annabeth's case - sure, they aged her up from twelve to sixteen, but that didn't stop Alexandria Daddario from being in her early twenties.
* The musical ''Theatre/NineMusical'' is about a filmmaker experiencing a mid-life crisis as he turns forty. For the film version, his age was upped to fifty to match Daniel Day-Lewis (52 in 2009, when the film was released).
* In every film and television version of ''Literature/WutheringHeights'', Heathcliff and Cathy are played by the adult actors during the scene where they eavesdrop on the Lintons, making giggling comments. In the novel they are children at this time, explaining their childish behavior. Catherine is only 19 when she ''dies''. Heathcliff was 20, and he was 16 when he ran away. No adaptation has even gotten close to the correct ages.
* ''{{Film/Watchmen}}'' has Silk Spectre II and the Comedian. In the original comic, the Comedian was 16 at the time of WWII while Silk Spectre was 19. In the film, they were aged up to their 20s since neither of the actors (Creator/CarlaGugino as Sally/Silk Spectre I and Jeffrey Dean Morgan as the Comedian) could pass for teens.
* In the book of ''Literature/AClockworkOrange'', the band of droogies were adolescents of 15. When Kubrick chose Malcolm Macdowell for the role of Alex, all were aged up accordingly. Echoes of the book occur when Alex is depicted as school age and when (years later) Dim describes himself and his partner as "of job age" in the scene where they torture Alex.
* Franchise/MarvelCinematicUniverse:
** In the original 1940s ''ComicBook/CaptainAmerica'' comics, ComicBook/BuckyBarnes was Cap's KidSidekick, and like the Robin example below, was very clearly intended to be a pre-teen. While modern retcons eventually established that the "KidSidekick" thing was a cover, to hide the fact that Bucky was a very young-looking teenager (15 in the beginning and a legal adult at 18 by the time of his "death," something the army would often look the other way about in those days) who doubled as a wetworks operative, the filmmakers behind ''Film/CaptainAmericaTheFirstAvenger'' decided to give him an additional bump up to his mid-to-late 20s. The [[Film/CaptainAmericaTheWinterSoldier second film]] gives his year of birth as 1916 or 1917 (the props don't agree), which actually makes him ''older'' than Cap, whose birth year is given as 1918 in the script. (and yet Creator/SebastianStan is actually a year younger than Creator/ChrisEvans...)
** In ''Film/IronMan2'', Justin Hammer is depicted as a middle-aged man and played by Creator/SamRockwell. This is in sharp contrast to the comics, where Hammer is an old man with an adult granddaughter.
** ''Film/AntMan'' has two major cases. In the comics, [[ComicBook/AntMan Hank Pym]] is roughly the same age as his contemporary heroes like [[ComicBook/IronMan Tony Stark]] and [[ComicBook/IncredibleHulk Bruce Banner]], but in the film, he's portrayed by 70-year-old Creator/MichaelDouglas. On the opposite end of the spectrum, you have Darren Cross, who is a middle-aged businessman with an adult son in the comics, but in the film is played by 38-year-old Corey Stoll.
** The MCU in general when it comes to ComicBook/NickFury and Comicbook/BlackWidow. In the comics, both of them were around during UsefulNotes/WorldWarII, but are OlderThanTheyLook thanks to some AppliedPhlebotinum. The movies indicate they're roughly the same age as their actors, Creator/SamuelLJackson and Creator/ScarlettJohansson, with ''Film/CaptainAmericaTheWinterSoldier'' explicitly giving Black Widow's birth year as 1984.
** Franchise/SpiderMan's alter ego Peter Parker and ComicBook/JessicaJones were in high school together in the comics, with Jessica having a crush on Peter. During his debut in ''Film/CaptainAmericaCivilWar'', Peter is still a 15-year-old high schooler, while ''Series/JessicaJones2015'' has Jessica much older (the actresses for Jessica and her classmate-turned-adoptive sister [[Comicbook/PatsyWalker Trish Walker]] are in their 30s). This is at least partially due to the fact that the ''Jessica Jones'' series was written and conceived way before Marvel and Sony had worked out a deal to get Spider-Man into the MCU, meaning at the time, there was no real reason to make sure their ages lined up.
** On the subject of Spider-Man, [[https://twitter.com/OpTicHitch/status/883223578346434560 Aunt May has steadily become younger in the movies]] to make her more believable as someone around Peter's parents' age; after being in her seventies in the ''Film/SpiderManTrilogy'' and her sixties in ''Film/TheAmazingSpiderMan'', MCU Aunt May (pictured above) is portrayed by 50-year-old Creator/MarisaTomei. Befittingly, she's a CluelessDudeMagnet who's hit on by everyone from Iron Man to the Thai restaurant waiter.
** In the original ''ComicBook/GuardiansOfTheGalaxy'' comics, Yondu is a hero in his prime, but in addition to being [[AdaptationalVillainy pirate]], the [[Film/GuardiansOfTheGalaxy movie version]] portrays him as a grumpy old man.[[spoiler:[[Film/GuardiansOfTheGalaxyVol2 The sequel]] shows this isn't unique to Yondu, either, as Starhawk, Lady Starhawk and Charlie-27 are also much older than their comic counterparts.[[note]]If we're being technical, about a thousand years older than their comics counterparts, whose comic was set in the 31st century[[/note]]]]
** [[ComicBook/CaptainAmerica Steve Rogers]]' year of birth in the comics is usually circa 1922, DependingOnTheWriter, making him about 20 years old at the start of WWII and 23 by the time he's frozen. The movies push it back to 1918, so that he's about 24 at the start of the film and 26 or 27 by the end (slightly younger than Chris Evans, who was 29 shooting the first movie).
** In ''Film/BlackPanther'', T'Challa and Nakia are roughly the same age, and are childhood friends and former lovers. This is in ''sharp'' contrast to the comics, where Nakia was only a teenager and had an unrequited crush on T'Challa. Okoye was also a teenager in the comics, but is a grown woman in the film. In fact, her actress, Creator/DanaiGurira, is only about two years younger than Creator/ChadwickBoseman.
* ''Film/HarryPotter'':
** Though it seems odd, the film adaptations change the ages ''accidentally'' with Lily and James Potter. Looking at the flashback clips, the moving pictures, and the images in the Mirror of Erised, Lily and James appear to have been in their 30s or 40s when they had Harry. It could make sense, since their ages weren't revealed until the [[Literature/HarryPotterAndTheDeathlyHallows seventh book]], six years after the first movie had been made. Though the film versions of Harry's parents look quite middle-aged, the book version of Harry's parents were only 20 when they had Harry and 21 when they died. Then again, the whole film timeline seems to be shifted compared to the books - all the dates on the headstones remain the same (including Lily's and James'), but things that didn't exist when the books were set (such as the Millennium Bridge and Oyster card readers) appear, suggesting that Lily and James' generation were all ''born'' at the same time as in the books, but just took longer to have kids.
** Cho Chang is a year older than Harry in the books. A line from Hermione in the [[Film/HarryPotterAndTheOrderOfThePhoenix fifth film]] implies she is in the same year as them.
** Romilda Vane was two years younger than Harry and should have been in her fourth year when Harry was in his sixth year in ''Film/HarryPotterAndTheHalfBloodPrince''. Likewise Katie Bell is one year ahead of Harry and in her seventh year but is seen along with Romilda in the sixth years' potions class in the film.
* In the book of ''Literature/TuckEverlasting'', Winnie is eleven. To both fit the DawsonCasting of Alexis Bledel and lessen the weirdness of her romance with forever 17-year-old Tuck, she is aged up to 15 in the movie.
* The 1979 film ''Sidney Sheldon's Bloodline'' cast Creator/AudreyHepburn in a leading role. Hepburn was in her 50s, but the character was written as being in her 30s. Hepburn looked great, but could never pass for someone in her 30s, so not only did an age lift occur in the film, Sheldon went back and revised his own novel for new editions, raising the character's age to match that of the film.
* In the novel of ''Film/{{Beaches}}'', the friends Cee Cee and Bertie meet at the respective ages of ten and seven, and first reunite in their teens. The movie changes things so both are eleven when they first meet, then reunite when they're in their twenties. This was likely due to not wanting to cast separate actresses for the girls' teenage years, the fact that Creator/BetteMidler and Creator/BarbaraHershey couldn't play ''that'' young, and probably to have less of an age difference between the two characters.
* In all the Film/{{Superman}} movies, Superman's alien father Jor-El is played by middle-aged actors (Creator/MarlonBrando, Creator/RussellCrowe) with graying or silver hair. In the Superman comics, Jor-El was a young man who looked exactly like Superman when Krypton blew up (after all, Kal-El was a baby when his father died).
* ''Film/TheAddamsFamily'' movies feature Wednesday as a young teenager or tween, as opposed to the TV show in which she was a little girl.
* ''Film/TheKarateKid2010'' remake ages the main characters down from 17-18 year-olds to preteens.
* Literature/SnowWhite is 7 years old in the original fairytale. Most film adaptations age her up to around 16 at the youngest.
* In ''Film/TheDevilsArithmetic'' book, Hannah is twelve. In the film she is aged up to around seventeen (she is old enough to drive and get a tattoo). Rivka is ten in the books but is aged up to around fourteen or fifteen.
* ''Literature/TheChroniclesOfNarnia'':
** The Pevensie Children are a bit older in the Walden Media films than they were in the books. Peter is 13-14 but William Moseley was 16 when the first film was made. Caspian in the books is said to be the same age as Peter so the second film ages him up too. The age differences are notable in all of the actors since only a year has passed between the first and second films, but they were filmed three years apart.
** The '80s BBC adaptation also does this with Edmund and Lucy - their actor and actress were in their early teens, while in the books the characters are 10-13 and 8-11, respectively. Peter and Susan are the ages of their book counterparts, though - which creates the sense that Mr. and Mrs. Pevensie had all four of of their children in ''extremely'' short succession.
* Literature/MaryPoppins never reveals her age but is portrayed as an elderly woman in the books. In ''Film/MaryPoppins'' (1964) she is played by the 25-year-old Julie Andrews.
* ''Literature/LandOfOz'':
** Dorothy in ''Literature/TheWonderfulWizardOfOz'' is around seven or eight years old in the book. Judy Garland was seventeen when she played her in ''Film/TheWizardOfOz'' (Barry Norman's book ''The Hollywood Greats'' says Dorothy was meant to be twelve in the film).
** ''Film/ReturnToOz'' averts this by having Dorothy at eight, which is much closer to the books.
** Dorothy in ''Literature/TheWonderfulWizardOfOz'' is under ten and in ''Theater/TheWiz'' musical is a teenager. In the movie Dorothy is in her twenties and is a school teacher.
** In ''Literature/TheWonderfulWizardOfOz'', the Wicked Witch of the West is so old and evil that all the blood has dried up in her veins. In the [[Film/TheWizardOfOz MGM film]] she is aged down to be considerably more younger. While not young, she's certainly not a senior. Most adaptations use this interpretation.
* ''Film/EndersGame'' had to change the ages of most of the main characters to be more in their early teens. This is probably because one of the major problems with prior attempts to film the book was that a large portion of the cast is made up of children, and in addition to getting a sufficient number of good child actors the ones that were cast would keep growing up before it could enter production. It also probably didn't help that there was quite a bit of violence among the children in the book, at least two of whom were (unknowingly) murdered by Ender.
* The character of ComicBook/{{Robin}} as originated by Dick Grayson always has the origin of [[DeathByOriginStory his parents being killed]] during a circus act when he was a pre-teen, not too different than with his adopted father [[Franchise/{{Batman}} Bruce Wayne]]. ''Film/BatmanForever'' cast 25-year-old Chris O'Donnell in the role and Bruce comments that his superhero name should be "Dick Grayson, College Student" and that is as far as they get to identifying his age. It has the side effect of conflating his history and personality as both Robin and ComicBook/{{Nightwing}}, being pragmatic for a film adaptation.
* In the ''Film/QueenOfTheDamned'' film, the character of David Talbot, the Superior General of the Talamasca Caste, a paranormal research society, is played by the (then) 42-year-old Creator/PaulMcGann. However, in the novel, he is in his 80s and is nearing the end of his long and full life. Ditto for Jessie Reeves, played by MargueriteMoreau (24 at the time), who is supposed to be 35 in the novel, although this can also fit under HollywoodOld.
* ''Film/KissKissBangBang'' had Creator/RobertDowneyJr (born 1965) and Michelle Monaghan (born 1976) play characters who had known each other as kids, with his character having a crush on hers. Robert Downey, Jr is a handsome man but he looks his age so the apparent age gap was {{Handwaved}} by showing he had had a hard life as a petty thief in the years since and also have Monaghan play slightly older than her real life age.
* ''Theatre/TheCrucible'' is based on true events, but the affair between Abigail Williams and John Proctor was not one of them. In real life Abigal was 11 and John was in his 60s.
* Franchise/DCExtendedUniverse:
** Typically, Superman, Batman, Wonder Woman, Aquaman, and the Barry Allen Flash have been portrayed as being roughly the same age (early-to-mid 20s at the start of their careers), give or take a couple of years, and started their careers around the same time with Cyborg as a teenager (and before ''The ComicBook/New52'', originally only becoming a superhero years later to boot). In this universe, though, Clark Kent is in his early 30s and has just started his career as Superman, Bruce Wayne is in his mid 40s and has had a 20 year career as Batman, Diana of Themyscira is thousands of years old and fought in World War I, and if their actor's ages are anything to go by, Aquaman is in his late 30s, Barry (like in ''Series/TheFlash2014'') is quite a bit younger (early 20s) and not even in costume yet during ''Film/BatmanVSupermanDawnOfJustice''; and ''Film/JusticeLeague2017'' shows Cyborg is in the same age range, even if his actor was in his late 20s.
** Contrasting Batman, Jeremy Irons would be about the right age for an Alfred early in Batman's career, but next to Affleck he could almost pass for an older brother (in fact Creator/MichaelCaine, who [[Film/TheDarkKnightSaga previously played Alfred]], started the role a little older than Irons).
** The decision to cast Creator/JesseEisenberg as ComicBook/LexLuthor has already raised a few eyebrows among comic book fans. Though Luthor is a middle-aged businessman in the comics and in every other adaptation that isn't [[Series/{{Smallville}} a prequel]], Eisenberg is just thirty years old, and he's primarily known for [[DawsonCasting playing college-aged characters]].
** ''Film/WonderWoman2017'' takes place during UsefulNotes/WorldWarI, as opposed to UsefulNotes/WorldWarII likes the early comics or even the present day, making Steve Trevor and Etta Candy around 100+ years old if they're still alive, [[spoiler:though given the movie ended with him pulling a HeroicSacrifice before the war ended, Steve wouldn't be, anyway.]]
** ComicBook/{{Deathstroke}} is typically a decade or two older than Batman. Creator/JoeManganiello, who was cast as Slade in Creator/BenAffleck's solo ''Batman'' movie, is four years younger than Affleck.
* Jonas, Fiona, Asher, and their classmates were eleven going on twelve in ''Literature/TheGiver'' (the "graduation to adulthood" ceremony is called the "Ceremony of Twelve"), but have been aged up to sixteen for [[Film/TheGiver the movie]].
* Adaptations of Literature/AChristmasCarol often do this with Ebenezer Scrooge in order to empathise that this is his Last Chance to become a good man, casting him as a geriatric grumpy old man, while an close read of the book puts him at most in the mid-to-late fifties (his nephew, who Scrooge is distant to because he reminds him to much of his beloved sister who died young, possibly in child-birth, is in his mid-twenties). He is also stated to be spry enough to live long enough to become "almost an second father to Tiny Tim".
* ''Film/{{Blade}}'' does this to both the title character and Deacon Frost. Blade's year of birth was shifted from 1929 (hence being [[OlderThanTheyLook older than he looks]]) to 1967 and Stephen Dorff was cast as Deacon Frost, causing the character to have a younger appearance than the white-haired old man in the comics.
* ''Film/XMenFilmSeries'':
** In the comics, Cyclops, Jean Grey, Iceman, Beast, and Angel are roughly the same age, being the "First Class" with Beast as the eldest. In the movies, Iceman and Angel are quite a bit younger than Cyclops and Jean, and Beast is older than all of them, having a couple of decades on Scott and Jean.
** ''Film/XMenOriginsWolverine'' presents Bolt as a contemporary of Agent Zero, as opposed to his protégé.
** In addition to Beast, by deciding to avoid ComicBookTime with ''Film/XMenFirstClass'', ''Film/XMenDaysOfFuturePast'' and ''Film/XMenApocalypse'' ([[HollywoodOld even if it seems the characters aged just 5 years during a period that in-universe is stated to be 21]]), several characters are older than the main cast in the original trilogy. There's Havok, who's Cyclops' ''younger brother'' in the comics; Darwin, who's the same age as Havok and hence younger than the First Class of the comics; Quicksilver, Riptide and Emma Frost, who are the same age as the present day characters in the comics; Shaw, who isn't as long-lived as his movie counterpart; and Angel Salvadore, who's in fact younger than most of the characters in the original trilogy. The future of ''[=DoFP=]'' also does this to Bishop as his counterpart in the comics in a time traveler who has yet to be born in the present, yet his movie self is teammates with Blink, Sunspot, and Warpath.
** Going the other way, Iceman and Pyro are closer in age to Cyclops and Jean in the comics, yet their movie counterparts are younger, and Banshee was an adult when he joined the X-Men in the comics. Mystique is a couple of years younger than Professor Xavier in the movies whereas her comics counterpart is roughly the same age as ''Wolverine''.
** ''Film/XMenApocalypse'':
*** It {{retcon}}s away the ''Film/XMenTheLastStand'' versions of Angel and Psylocke, making them around the same age as Cyclops, Jean, and Storm as in the comics. It also retcons Jubilee into their classmate, as opposed to being a generation younger than them.
*** Nina (the AdaptationNameChange for Anya), who in the comics was Magneto's eldest child, but in the movie-verse, Quicksilver is. Nina is at least 18 years younger than Peter Maximoff.
** ''Film/{{Logan}}'':
*** ComicBook/{{X 23}} and Rictor are respectively a teenager and an adult in the comics. Here, they're little kids. X-23's age, however, is truer to her original age from ''WesternAnimation/XMenEvolution''.
*** Zander Rice is only in his 30s in the comics, but here, he's in his 60s.
** In ''Film/{{Deadpool 2}}'', Yukio is a teenager who appears to be roughly the same age as her girlfriend, Negasonic Teenage Warhead. In the comics, Yukio is an adult and seemingly around the same age as Comicbook/{{Storm}}.
* ''Film/VictorFrankenstein'': While this movie's Victor is a medical student, he's older than his book counterpart--the latter is in his 20s, but Creator/JamesMcAvoy was 34-35 years old during principal photography. While the actor is OlderThanTheyLook when clean-shaven, he always grows a beard for roles which require him to diminish his boyish appearance, so it indicates that his character is meant to be in his early 30s.
* ''Film/DeathHunt'': The real Edgar Millen was a popular young Constable who more closely resembled Constable Alvin Adams, the new rookie in the film. He's instead portrayed as a weary, alcoholic older Sergeant of the RCMP.
* Most adaptations of ''Literature/AlicesAdventuresInWonderland'' do this with the title character, who is only 7 years old in the books, but usually played by actresses who are at least 12, more often in their teens. The 1985 TV version and the [[NightmareFuel very surreal and creepy]] 1988 Czech version accurately portray her as a 7-year-old, though, as does [[Film/AliceInWonderland2010 Tim Burton's sequel]] in its prologue and flashbacks.
* ''Film/TheHungerGames'': Two examples: Firstly, Cinna, described as a young man in the book, is played by a much older Lenny Kravitz. Secondly, in an instance of inverted DawsonCasting, the character of Clove, heavily implied to be 18 in the book, is stated to be 15 in the film, as she is played by then-14-year-old Creator/IsabelleFuhrman.
* ''Film/JemAndTheHolograms'': In the [[WestenAnimation/{{Jem}} cartoon]] all of the women are adults, though Kimber is still in her teens (either eighteen or nineteen). In the film they are very noticeably aged down into high schoolers and are explicitly referred to as under eighteen.
* In ''Theatre/StateOfTheUnion'', Katherine "Kay" Thorndyke is a divorcée "in her late thirties," according to the play script. The film version cast Creator/AngelaLansbury in her early twenties and added a new opening scene to establish ''Miss'' Thorndyke as a young heiress.
* The 1994 MadeForTVMovie of ''Literature/AliceThroughTheLookingGlass'', opens with a small girl having the book read to her by her mother, played by Kate Beckinsdale. It's the twentysomething mother who travels through the looking glass and becomes Alice.
* In the book and made-for-tv versions of ''Literature/BridgeToTerabithia'' Leslie and Jesse are ten. The 2008 film aged them up to twelve.
* The ''Film/{{Monsterverse}}'' sees this as ''Film/{{Godzilla 2014}}'' paints Godzilla as an older dinosaur than his Toho counterparts and TheStinger for ''Film/KongSkullIsland'' paints Rodan, Mothra, and King Ghidorah as having been around as long as Godzilla. Conversely, King Kong himself is a teenager in the 1970s.
* ''Film/TheAmazingSpiderMan2'' sees then 62 year old Creator/ChrisCooper play ComicBook/NormanOsborn, who was canonically established on Creator/MarkMillar's run on the Marvel Knights ''Spider-Man'' title to be in his mid-fifties at the time, which given those comics had a 20+ year old Peter Parker and the film had a teen Peter like the early comics, means a faithful Osborn would be in his 40s.
* ''Film/IShotJesseJames'' is an interesting case, as it age lifts [[HistoricalDomainCharacter real-life people]]. The most notable case is Edward O’Kelley (known as [[AdaptationNameChange John Kelley]] in this film), who was around 25 years old in 1882 and 35 years old in 1892. Here, he’s played by the 49 year-old Preston Foster in both time periods and treated as significantly older than Robert Ford (who was only five years younger than O'Kelley in real life). This is even more noticeable for Soapy. The real Soapy Smith was in his twenties and thirties during this film’s timeframe. Here, he’s portrayed by Victor Kilian, who was 58 at the time and is treated as an old man.
* ''Film/CloudAtlas'': In the book, Zachry is a young man who lives with his mother and siblings. In the film, he's a middle-aged man living with his widowed sister and niece. The change was necessary for Tom Hanks to play the part.
* Jack in ''Theatre/IntoTheWoods'' is usually portrayed by an actor in his late teens, and in the end when [[spoiler: his mother dies, and he left to wonder who will take care of him, the Baker tells him he's old enough to start taking care of himself,]] but in [[Film/IntoTheWoods the movie,]] Jack appears to have not hit puberty yet, making him closer to the age he's usually depicted in Jack and the Beanstalk.

* In an extreme example, the novel ''Nutshell'' by Ian [=MacEwan=] is a SettingUpdate of ''Theatre/{{Hamlet}}'', whose Hamlet character (who is also the narrator) ''hasn't been born yet''.
* The Literature/TanteiTeamKZJikenNote series begins with adopting an old LightNovel series for [[ChildrensLiterature tweens]] [[{{Shoujo}} girls]]. As a result, the age of the cast was moved down for several years; luck was that elementary schoolers go to CramSchool as well, keeping a key premise element intact. As a side effect, sometimes the cast don't act like 12-year-olds; for example, [[spoiler:a 12-year old boy made a big marriage proposal to a girl of the same age ''through her parents'', and the said parents ''do not object''.]]

[[folder:Live-Action TV]]
* In the ''Literature/{{Animorphs}}'' book series, the characters age from 13 in book 1 to 16 in book 54. In the [[Series/{{Animorphs}} short-lived TV series]], though, the characters start out as 15- and 16-year-olds (played by actors as old as 25). In all fairness, as part of the series' conceit that it was [[LiteraryAgentHypothesis secret accounts of a guerilla war]], the characters deliberately obscured their ages; that they were 13 in the beginning wasn't revealed until the second-to-last book, and the show was canceled ''long'' before then. There is some evidence to their age long before the last book. Tobias describes Jake as a "typical middle school kid" in an early book, which means the Animorphs must be between the ages of 11 and 14.
* In the ''Literature/TheSouthernVampireMysteries'', the character of Pam is stated to have been nineteen when she was turned into a vampire. The producers of the TV adaptation ''Series/TrueBlood'' cast the fortysomething actress Kristin Bauer van Straten as Pam and gave her the backstory of being a madam of a brothel, an occupation traditionally for an older woman.
* In the definitive adaptation of ''Literature/AnneOfGreenGables'', Megan Follows, who was seventeen at the time, played an Anne Shirley who was advanced in-text from eleven to thirteen years old. Not, perhaps, a vast difference (Follows is still effective in the role), but the scatterbrained, temperamental, and openly imaginative character seems exaggerated when she's aged up.
* In the 1930s film of ''Literature/AnneOfGreenGables'' starring sixteen-year-old Anne Shirley - the actress who took the character's name for her own - Anne is stated to be fourteen.
* ''{{Series/Deadwood}}'' is only VeryLooselyBasedOnATrueStory, so a lot about the real-life characters are rewritten. For exaple, Al Swearengen was a just-married 31 year-old man from Iowa in 1876, while the TV character is a single, globe-trotting Englishman in his 60s.
* Literature/JesseStone is in his mid-thirties in the novel series, while in the TV movies he's played by Creator/TomSelleck, who's in his 60s. Despite this [[WordOfGod Robert B. Parker himself]] approved and said Selleck nailed the role.
* On ''Series/TheTwilightZone1959'', Anthony from [[Literature/ItsAGoodLife "It's A Good Life"]]" was aged up from three years old to six, as a toddler couldn't have been relied on to act a part or been given any lines.
* ''Series/TheWorstWitch'':
** The girls in the books were around eleven or twelve but appear to be around sixteen by the third season of the TV series. So notable that the fourth season was changed to a college setting because it would have no longer be believable that Mildred would still be at school.
** Miss Drill was also a strict older woman like the rest of the teachers in the books. In the TV series she is a much younger woman. This is addressed in-universe as Miss Drill is frequently at odds with the traditional older teachers.
* In ''Series/{{Sherlock}}'', Professor James Moriarty, the elderly, doddering math teacher, becomes the young, suave, snappy-dressing career criminal ''Jim'' Moriarty. Tellingly, where the literary Moriarty assumed the cover identity of a university professor [[VillainWithGoodPublicity to keep his reputation clean]], the series' version [[spoiler: does the same thing by crafting a cover identity as a television actor]].
* ''Series/{{Salem}}'': Massively done with John Alden. [[http://en.wikipedia.org/wiki/John_Alden_%28sailor%29 The real man]] was born in 1626/1627, which would make him around 66 years old at the time of the witch trials, while in the show he's played by Shane West, a man in his 30s.
* ''Series/{{Gotham}}'' has some characters from Batman universe that are older then the comic book's versions:
** While the Penguin is generally depicted as older than Batman, he is now apparently around Gordon's age, which makes the age difference somewhat larger.
** Bullock is a little older than Gordon is. He looks the same age as his comics counterpart who reports to an older Commissioner Gordon. Likewise, Sarah Essen is older than Gordon, as opposed to being younger than him.
** Riddler, Renee Montonya, Crispus Allen, Victor Zsasz, Harvey Dent, and Mario Falcone are now apparently around Gordon's age, while usually they are closer to Batman's age. Likewise, Cosmo Krank/The Toymaker, a character created for ''WesternAnimation/TheBatman'' was depicted as around Bruce's age in that show and already an adult in ''Gotham''.
** Carmine Falcone is already quite old at this point. He is played by 70-year-old Creator/JohnDoman, and in his first appearance, he mentions being good friends with Gordon's father. In the comics, he is around this age by the time Batman arrives.
** Bruce Wayne is 12 instead of 8 when his parents die; Selina Kyle (the future Catwoman) is maybe a couple years older. Given they're regular characters with a lot of heavy dramatic material to carry, it was probably necessary to tell the story as intended here.
** Matches Malone is a case of VagueAge, but in the comics, he's young enough for Batman to pull a successful DeadPersonImpersonation once he believes Malone is dead and use his identity to spy on criminals. Here, he's already an adult while Bruce is a kid.
** Most versions of ComicBook/RasAlGhul are around 400-700 years old. This version? Over 2,000.
** One of few characters to go the other way is Leslie Thompkins - her actress Creator/MorenaBaccarin was 35 when she started the role and is only about 8 months younger than Creator/BenjaminMcKenzie (James Gordon), while in the comics she's depicted as a contemporary of Alfred Pennyworth (played by 50-year-old Sean Pertwee) and old friend of Thomas and Martha Wayne (the former of whom was played by 44-year old Grayson McCouch). Pennyworth himself is a case of VagueAge concerning his age relative to Bruce Wayne's, but as a whole averts this trope.
* ''Series/OnceUponATime'' does this with a few fairy tale and Disney characters:
** Ariel was sixteen in [[Disney/TheLittleMermaid her film]]. Here she is at least late twenties-early thirties.
** Snow White (as noted above) is seven in the original tale and fourteen in the Disney film. She's in her twenties.
** Peter Pan is eternally five or six in the novel (he's said to still have his baby teeth). His actor Robbie Kaye was seventeen at the time of filming. What's more is that [[spoiler: he's really a man in his (physical) 40s de-aged by magic]].
** Red Riding Hood is often written as a preteen. Here she is around 18-21
** Cinderella's FairyGodmother is portrayed as an elderly woman in the Disney film. Her brief appearance has her significantly younger.
** The Mad Hatter is often portrayed as an elderly man. Here he's in his 20s.
** The Wizard of Oz is an older man too but is played by a younger actor.
** Although a minor character, the Good Witch of the North is an older woman. She's played by a young actress.
* ''Series/AgentsOfSHIELD'':
** Donnie Gill, an adult in the comics, is depicted as an 18-year-old S.H.I.E.L.D. cadet.
** There's Eric Koenig and his "brothers". In the comics, Koenig is a veteran of UsefulNotes/WorldWarII and would have to ''at least'' be in his 80s, while in the show, he and his brothers are played by 46-year-old Creator/PattonOswalt.
** [[spoiler: Jeffrey Mace in the comics was one of the men who filled in for Steve Rogers as Captain America when he was still in ice. Here, he's played by 44-year old Creator/JasonOMara and is a present day character, replacing Coulson as the head of S.H.I.E.L.D. once it once again becomes an official agency.]]
* ''Series/{{Daredevil 2015}}'' has the Owl, who is usually middle-aged in the comics, played by Bob Gunton, who is 70. However, the fact that Leland Owsley is mentioned to have a son named Lee (who'd probably be the right age), and that he never becomes the Owl [[spoiler:before his death]] strongly suggests this to actually be a case of DecompositeCharacter in play.
* ''Series/JessicaJones2015'': As noted above in "Film", the title character and Peter Parker were in high school together when the latter started his career as Franchise/SpiderMan, but because the TV show was written before Spider-Man joined the [[Franchise/MarvelCinematicUniverse MCU]] (and before anyone working on the show had any idea how he would be integrated), Jessica is a grown woman when Peter is only 15. Somewhat moot in that Spider-Man doesn't actually appear on the show, though.
* ''Series/AgentCarter'' is set not long after World War II and features Whitney Frost, Joseph Manfredi, and Roger Dooley--all three being ''present day'' characters, with Dooley notoriously having sexually harassed She-Hulk, Frost being the supervillainess Madame Masque and a frequent enemy of Iron Man, and Mandfredi likewise being the supervillain Blackwing and having fought Captain America and Daredevil (and his father being the ''Spider-Man'' villain Silvermane).
* ''Series/{{Supergirl|2015}}'':
** Kara is usually in her teens when she becomes Supergirl (she was 15 when she first debuted in the comics), but on the show, she starts out at the age of 24. This prompted an in-universe discussion about why a grown adult would call herself Super''girl'' and not Super''woman''.
** Likewise, in both the comics and ''WesternAnimation/YoungJustice'', Miss Martian was a teenager, and even attended high school in her Megan Morse identity. In the live-action show, Megan is in her 20s and works as a bartender.
* ''Series/{{Smallville}}'' did the same thing, having Kara be around 19 when she first showed up.
* The premise of ''Series/{{Younger}}'' is essentially giving Liza an InUniverse Age Lift, de-aging her with the help of fashion and Internet scrubbing in order to make her appear age-appropriate for her new career.
* ''Series/{{Shadowhunters}}'':
** Clary Fray turned 16 2/3rds of the way through ''Literature/{{City of Bones|2007}}'', here she starts off the series celebrating her 18th birthday.
** Simon Lewis was 17 in the books, but says he's 18 in the fourth episode.
** Jace Wayland is 17 in the book, but in his early twenties 20s in the show.
** Madame Dorothea was an old woman in ''Literature/{{City of Bones|2007}}'', but in the show her counterpart Dot is only in her thirties.
** Maureen Brown is 14 ([[OlderThanTheyLook but looks about 12]]) in the books, but on the show she's around the same age as Clary and Simon, who are already older than their book counterparts.
* In ''Literature/TheVampireDiaries'' books, Elena has a four-year-old sister. In [[Series/TheVampireDiaries the show]], she has a 15-year-old brother.
* ''Series/{{Poldark}}'': Demelza is 13 at the start of the first book, and she seems to be closer to 17 in the show, which is good as [[spoiler:she has sex with Ross]] in episode 3.
* ''Series/TheMagicians2016'': Dean Fogg was an old man in [[Literature/TheMagicians the books]]. Here he's in his late forties at most.
* ''Series/{{Elementary}}'': Moriarty is in [[spoiler:her]] mid thirties to early forties instead of being several years older like in the books.
* ''Series/{{Arrowverse}}'':
** ''Series/{{Arrow}}'':
*** In the comics, Roy was young enough to be adopted as Oliver's ward, like Dick Grayson to Batman. In the show, they're closer in age to the point they're more like brothers. Similarly, Mia Dearden (Thea's comic book counterpart) is a young teenager when her and Oliver first meet (around 16), and is at least a decade younger than Roy. While Roy's exact age isn't clarified in the show, she's 17/18 in the first season when the two start dating, implying he's only in his early twenties at most.
*** Similarly, Dinah Laurel Lance/Black Canary started her crime fighting career when she was in her late teens, and was around 19 when she joined the Justice League and first met Oliver (who was a good few years older than her). In the show, the two went to school together and are the same age. Likewise, the first Black Canary, Dinah Drake, is usually significantly older, having fought crime long before Oliver started, but in the show, Sara Lance, the show's version of the first Canary, is actually ''younger'' than Oliver and Laurel by a few years, being Laurel's younger sister instead of her mom.
*** In the comics, Felicity Smoak is Ronnie Raymond's stepmother, but the show first sees her at 23.
*** Sin in the comics is an little girl, but the series depicts her as a teenager.
*** Jean Loring is the same age as Moira Queen and hence older than Ray Palmer.
*** Ted Grant/Wildcat is usually a Badass Grandpa in the comics (post-Golden Age), while he's played by J.R. Ramirez in the show, who is in his 30's.
*** Cynthia Addai-Robinson, an actress in her 20s during Season 2, played the traditionally middle-aged Amanda Waller.
*** Lyla Michaels, a.k.a. Harbinger, is depicted in the show as an adult, as opposed to the teenager of the comics.
*** ComicBook/{{Deathstroke}} is commonly depicted as an old man. Here, he's in his 40s (in the present day scenes at least). William Wintergreen, who is commonly depicted as Slade's ''much'' OlderSidekick is also younger, being the same age as Slade.
*** In the comics, ComicBook/RasAlGhul is 600+. Being Ra's in this is a DecompositeCharacter and LegacyCharacter, he's only 200.
*** Comics Darhk is a young man comparable in age to several of the older Teen Titans members. In the series, he's played by 49 year old Neal [=McDonough=]--and additionally ''Arrow''!Darhk is a peer of Ra's al Ghul.
*** Count Vertigo is usually a middle-aged man, but in ''Arrow'', going by Seth Gabel's age, only in his 30s.
** ''Series/TheFlash2014''
*** Barry himself is bit younger than his usual depictions, which is actually turned into a plot point when it's revealed that the "Man in Yellow" turned him into the Flash seven years early (giving Barry his powers in 2013 instead of 2020).
*** Wally West is only a few years younger than Barry and Iris whereas in the comics the age gap is wider due to them being in their late 20-early 30 and Wally being a teenager at first.
*** Ronnie Raymond is traditionally a teenager when he becomes the superhero Firestorm; here, he's roughly in his mid-to-late twenties. Jason Rusch is likewise a grad student in the show, not a high school student.
*** Girder, Peek-A-Boo, and Tar Pit are foes of Wally in the comics, but here's they're the same age as Barry and among his enemies. Girder himself in the comics is a middle-aged man.
*** Tokamak is an old man in the comics, but around Barry's age on the show.
*** Played with Griffin Grey. He is currently 18 years old but got his powers at 16, which is part of the age group he belongs to in the comics. However, he's around that age during a much earlier point in time of his existence in the comics, where he was the same age as Impulse, Barry's grandson.
*** Dante Ramon and Vibe are close in age in the comics, but Dante is 13 years older than Cisco in the show.
*** Thanks to Creator/MarkHamill [[RoleReprisal coming back to play]] [[Series/TheFlash1990 the Trickster once more]], James Jesse is depicted as middle-aged. Likewise, due to the return of Amanda Pays as Tina [=McGee=], Tina is middle-aged herself.
*** [[spoiler: Hunter Zolomon has a few years on Barry in the show whereas his comics counterpart as a foe of Wally West and close to Wally in age. When he impersonated Jay Garrick, he seemed to be this for Jay as well, being around his 30s, but the real Jay Garrick averted this, being middle-aged.]]
** ''Series/{{Constantine}}'':
*** Sister Anne-Marie Flynn in the comics was an old woman. The series version is John's age.
*** Jim Corrigan is much younger than his comic counterpart, who was around during WWII, and he's yet to become the Spectre.
** ''Series/LegendsOfTomorrow'':
*** ComicBook/VandalSavage as a CompositeCharacter with elements of Hath-Set and having his origin ties to Hawkman's, he's only been alive since Ancient Egypt and isn't a caveman.
*** In the comics, Grant Wilson is Slade's eldest child. Given his apparent age at 2046 and the flashbacks on Arrow set in the late 2000s where Slade only mentions Joe, it's very likely that Joe is the older brother here. Another one of Slade's child in the comics, Rose Wilson, was [[CompositeCharacter fused with Isabel Rochev]].
*** Usually depicted in her twenties or early thirties in modern times (her parents met at Woodstock according to a 1992 story), the series's Talia al Ghul would be in her sixties in 2016, assuming she didn't use the Lazarus Pit to stall her aging like Ra's and Darhk have.
*** Obsidian and Stargirl are both members of the original JSA during UsefulNotes/WorldWarII, rather than second-generation members of the team. In a later episode 76-year old Creator/LanceHenriksen plays Obsidian in TheEighties.
* ''Series/TheWalkingDead'' sees the old Ezekiel played by 44-year old Creator/KharyPayton.
* ''Series/EmeraldCity'':
** Dorothy has gone from the young girl in the ''Literature/LandOfOz'' books to a young adult in her early twenties.
** The Wicked Witches of the East and West were depicted as old hags in the books, but are played here by 40-year-old Creator/FlorenceKasumba and 31-year-old Creator/AnaUlaru respectively. However, they are also hinted to be OlderThanTheyLook.
* In ''ComicBook/{{Runaways}}'', Molly starts off as an 11-year-old who may or may not be starting puberty in the first issue. In the TV adaptation, she's played by 15-year-old Allegra Acosta. She's still TheBabyOfTheBunch, but it's not as obvious.
* ''Series/TheHandmaidsTale'': The Commander is older, probably middle-aged at least in the novel. In the series he's played by forty six year old Joseph Fiennes. Serena Joy is also described as being older. Here it's Yvonne Strahovski playing her, who's the same age as Elisabeth Moss, who plays Offred.

[[folder:Tabletop Games]]
* ''TabletopGame/CandyLand'':
** Queen Frostine is no longer a Queen. She's younger and is a princess. As a result of her age decreasing, she is no longer married to King Kandy (he is her father now) and she is Lolly's sister, instead of her mother.
** The age of Princess Lolly has zig-zagged over the years. As of 2013 she looks much older than her traditional design.
** In the 80s and 90s King Kandy became a younger man with red hair. He has since returned to his older, grey haired version.

* ''Theatre/{{Hamlet}}'', the former TropeNamer, is a tough call. The play has contradictory lines about the prince's age - some evidence suggesting he's thirty or older, other lines indicating he's a fresh-faced college undergrad. Plus, the role has acquired a reputation as being the "crown jewel" of an actor's career, so you'll find men cast as Hamlet when they're in middle-age, usually at the height of their fame.
* The ScreenToStageAdaptation of ''Literature/TheSecretGarden'' ages Dickon Snowbery from 12 to a young man.
* In the stage production of ''Theatre/TheAddamsFamily'', Wednesday's age is changed from 10 or so to about 18. (Pugsley, however, is still a young child.)
* Dorothy is a teenager in ''Theatre/TheWiz'' instead of the prepubescent child she is in the books.
* For the musical version of ''Theatre/TheBridgesOfMadisonCounty'', Francesca and Robert are aged down from middle age to approximately 40.
* In ''Literature/{{Matilda}}'', Michael Wormwood is stated to be five years older than his sister Matilda, making him 10 in the book. [[Theatre/{{Matilda}} The musical adaptation]] makes him a teenager played by an adult, presumably to have one less child role that would need to be double cast.

[[folder:Video Games]]
* Like the anime example above, many video games from Japan released in the west will age the characters up to at least 18 for the same reason. If that's not enough, female characters of questionable age with {{Stripperific}} outfits whether it's a customized clothing option [[DigitalBikini will be more covered up]] or removed completely.
* Lyn was 15 (at the start of) the original Japanese version of ''VideoGame/FireEmblemTheBlazingBlade''. The localized version aged her up to 18 for some reason, despite her acting basically the same age as her co-leads Hector and Eliwood (about 17, following the 1-year TimeSkip and a vague number of time during gameplay). It's likely due to her looks/curves, YoungerThanSheLooks in short.
* In the original Japanese version of ''VisualNovel/SweetFuseAtYourSide'', Saki is 17 years old and Wakasa is 15. Since ''Sweet Fuse'' is a RomanceGame and Saki's other prospective love interests range in age from 22 to 32, the English localization by Aksys Games nudges her age up to 18 and Wakasa's to 17.
* ''VideoGame/BravelyDefaultFlyingFairy'': Releases outside of Japan aged up the protagonists from 15- to 16-year-olds to 18. This is mainly due to the more {{Stripperific}} outfits the girls get to wear (some of which were also toned down a little), and the game's very dark themes - particularly [[spoiler:a rather infamous side-quest that [[DoesThisRemindYouOfAnything very closely resembles a]] [[RapeAsDrama date-rape plot]], which one of your female party members has to fall victim to in order to progress]].
* ''VideoGame/PuzzleQuest:Challenge of the Warlords'': Princess Seraphine, introduced as the player is to escort her to her ArrangedMarriage, is 16 in the original PC version. She's 18 in the subsequent console and portable ports.
* ''Franchise/SonicTheHedgehog'': The ''Sonic the Hedgehog Technical Files'' stated that Sonic's age was "18 (but it's kind of hard to tell)", Tails was 10, and Knuckles was 15. By the Saturn era Sonic's original age was 16, Tails was 8, Knuckles was still 15, and Amy was just 8 years old. When ''VideoGame/SonicAdventure'' was released Sonic became 15, Tails stayed 8, Knuckles became 16, and Amy became 12.
* In the original ''VideoGame/HarvestMoonAWonderfulLife'' Lumina is a fourteen-year-old girl with a PrecociousCrush on the protagonist. In ''Another Wonderful Life'', where you play as a woman, she was made into a rival for Rock, who is in his twenties. Lumina was upped to sixteen in Japan, eighteen internationally, and that has been her starting age in every game she's appeared in since.
* ''VideoGame/BatmanArkhamSeries''
** The ''Arkham'' version of Tim Drake is older than the comics version, being closer in age to Dick Grayson and Barbara Gordon [[spoiler: and in the GoldenEnding of ''VideoGame/BatmanArkhamKnight'', ends up marrying Barbara.]]
** ''Knight''[='=]s DLC expansion pack, "Season of Infamy", included Talia's sister, Nyssa Raatko, and has her as Talia's ''younger'' sister. In comics canon, Nyssa is a Holocaust survivor and Talia's mother met ComicBook/RasAlGhul at Woodstock.
** In the comics, Lonnie Machin was a 12 year old kid when he became ComicBook/{{Anarky}}--which was shortly before a 14-year old Tim Drake became assumed the Robin mantle[[note]]a month real time between Anarky's debut in ''Detective Comics'' #608 in November 1989 and Tim donning the Robin costume in ''Batman'' #442 in December on the same year[[/note]]. ''VideoGame/BatmanArkhamOrigins'' shows Machin as a teenager during Bruce's second year as Batman.
* For the English localization of ''VideoGame/TokyoMirageSessionsFE'' Tsubasa, Itsuki, and Touma were aged up from seventeen to eighteen.
* Traditionally in the comics, the Penguin has a few years on Batman, but in ''VideoGame/BatmanTheTelltaleSeries'', Oswald Cobblepot is the same age as Bruce and they even went to school together.
** The Riddler, as he appears in Season Two, is sixty years old and was a criminal back during Thomas Wayne's time.
* Very early documents about the ''Franchise/SuperMarioBros.'' call Mario a middle aged man, but by the time the 2000s rolled around he had been aged down into his mid-twenties.
* The various iterations of Impa from ''Franchise/TheLegendOfZelda'' have frequently had her age changed across the games (and it's more noticeable with her than with Link and Zelda, who are similarly {{Legacy Character}}s but who have more consistently been portrayed as pre-teens or teenagers). The [[AllThereInTheManual manuals]] for [[VideoGame/TheLegendOfZeldaI the first game]] and ''VideoGame/ZeldaIITheAdventureOfLink'' portray her as an OldRetainer, but in ''VideoGame/TheLegendOfZeldaOcarinaOfTime'' she's middle aged at the oldest (her former elderly version is referenced by reinterpreting her aged whitened hair as MysticalWhiteHair, a feature [[PlanetOfCopyhats later extended to the entirety of her Sheikah tribe]]). ''VideoGame/TheLegendOfZeldaSkywardSword'' made her even younger, barely older than the teenaged Zelda [[spoiler:though it's revealed the unnamed Old Woman who helps Link throughout the plot is actually a future Impa who took TheSlowPath to guard the sleeping Zelda in the Sealed Temple]]. She's back to being an old woman in ''VideoGame/TheLegendOfZeldaBreathOfTheWild''.

[[folder:Visual Novels]]
* All Western-released materials of ''VisualNovel/FateStayNight'' come with a disclaimer that [[TotallyEighteen all of the characters are 18 or older]] in order to make the sex scenes legal, despite Shirou, Rin, and Sakura being in their second year in high school — making them between 16 and 17 in the Japanese version — with Saber being physically a year younger.

[[folder:Web Animation]]
* ''WebAnimation/DCSuperheroGirls'', where dozens of 20-something and 30-something characters are aged down into high schoolers. It isn't terribly consistent with who gets de-aged though, as Franchise/{{Batman}} and Franchise/{{Superman}} are adults yet Franchise/WonderWoman, [[Franchise/TheFlash Barry Allen]], and [[Franchise/GreenLantern Hal Jordan]] are teenagers.

[[folder:Web Comics]]
* In ''Webcomic/FiveKidsAtFreddys'', one of the missing children is actually a teenager, in order to make storytelling easier with a MinimalistCast.
* The Lithuanian translation of ''Webcomic/{{Homestuck}}'' changes the ages of the main heroes from 13 to 16, explaining it by the fact that it began precisely three years after the original.

[[folder:Web Original]]
* ''WebVideo/TheAutobiographyOfJaneEyre'' is a SettingUpdate of ''Literature/JaneEyre''. Lots of changes in characters' ages were done; mostly because the production team of the webseries were recent graduates when they started, and some of them were friends from school, which means they are more or less the same age:
** Jane Eyre was 18 in the novel; here she's 21 and a college graduate with a degree in nursing. Her actress is 24.
** Grace Poole is a CompositeCharacter, combining weird and mysterious Grace Poole with caring and friendly Mrs Fairfax. She's ''significantly'' younger than both women of the book, especially Mrs Fairfax who was probably in her fifties or sixties. It shouldn't hurt the story, though, except that the audience could cringe that there are no old people.
** Mr Rochester is thirty-sh. He is younger than his book equivalent who was in his mid-to-late thirties. The age gap between him and Jane was important for the story; it's smaller here, but it still applies.
* ''WebVideo/TheLizzieBennetDiaries'' is a SettingUpdate of ''Literature/PrideAndPrejudice''. Several changes regarding ages were employed, mostly to set some characters in graduate school or avoid unfortunate implications or plot holes. Some characters were still teenagers in the book. In the modern day States, a twenty-something is seducing or abusing a fifteen-year-old girl? Call the police and arrest that pervert.
** Lydia Bennet turned 21 in the web series. In the book, she was 15.
** Gigi Darcy is in her early twenties. Miss Darcy was 16 in the novel.
** Elizabeth Bennet was 20, and it was lifted to 24 with Lizzie.
** Charlotte Lucas was 27 in the book; Charlotte Lu is 24 as Lizzie: they are best friends ever and go together to graduate school.
** Jane Bennet was 23 in the novel; here she's still the eldest sister, so she's obviously older. The writers have stated she's 'around thirty'.

[[folder:Western Animation]]
* A variation with Aishling in ''WesternAnimation/TheSecretOfKells''. The character is based on a genre of Irish poetry where a spirit representing Ireland itself appears, taking the form of an older woman. However instead of a wise older woman, Aishling is a mischievous little girl.
* ''WesternAnimation/{{Caillou}}'' is bald because in the original books he was meant to be a baby barely over 1 years old. The cartoon aged him up to 4 but kept his lack of hair.
* In the original WesternAnimation/InspectorGadget cartoon, Gadget's niece Penny was a young child. The new [[WesternAnimation/InspectorGadget2015 2015 cartoon]] will make her a teenager.
* Many, if not most, of the ''WesternAnimation/TeenTitans'' were adults during ''[[ComicBook/TeenTitans The New Teen Titans]]'' run but are ambiguously between thirteen and seventeen, depending on the character, in the cartoon.
* ''WesternAnimation/XMenEvolution'' turns [[ComicBook/XMen Cyclops, Jean Grey and Nightcrawler]] into teenagers, and ages Storm and Beast to middle-age. It's a downplayed case for the first two since they were teens in the earliest comics. It also turns many of the Brotherhood members into teenagers, too, and Destiny is significantly younger than in the comics, looking like she's in her 40s ''at the most''.
* ''WesternAnimation/TeenageMutantNinjaTurtles2012'' turns April into a teenager, who has always been somewhere in her early 20's in all other incarnations of the franchise. This applies to Casey Jones as well when he's introduced in the second season. This seems to have largely been done to have them the same age as the titular characters (while averting ArtifactTitle), which among other things makes their closeness a bit less unusual[[note]]which is to say, more "realistic"[[/note]] and (perhaps more prudently) the ShipTease with Donatello and April more palatable. However, it was most likely done for a more spur-of-the-moment reason: to set up her grudge with the Turtles in this version after they [[spoiler:accidentally cause her father (who was invented for this incarnation, possibly for this purpose) to get mutated]].
* ''WesternAnimation/UltimateSpiderMan'' does with Luke Cage, Iron Fist, Rhino, Ka-Zar, Vulture, and Triton, making them Spidey's age rather than older. It also follows the ''Ultimate'' comics example of putting Mary Jane Watson and Harry Osborn in high school with Peter, too. Aunt May is also noticeably younger looking and more athletic than her mainline comics counterpart.
* ''WesternAnimation/BatmanTheBraveAndTheBold'' has Mark Desmond (Blockbuster) as the same age as [[Comicbook/{{Shazam}} Billy Batson]] (and in the same school), to draw parallels with them both having a superstrong, adult alter ego.
* ''WesternAnimation/TheBatman''
** Traditionally, the Penguin is older than Batman. However, the Penguin is around the same age as Batman.
** Alfred appears to be middle-aged rather than elderly, though his exact age isn't stated.
** While Barbara Gordon is around the same age that she's usually depicted as (late teens-ish), she's a few years older than Dick Grayson here, though she also was older than Dick in the comics until a {{retcon}} made them the same age.
* Inverted with Tails in ''WesternAnimation/AdventuresOfSonicTheHedgehog''. His game counterpart is 8 however Tails was significantly aged down to 4 1/2 in the cartoon. In ''WesternAnimation/SonicSatAm'' this would have been played straight with Tails being 10 years old... except for the fact he is treated like a kid, rather than the ChildProdigy he is in the games, ''Anime/SonicX'' and even ''WesternAnimation/SonicBoom''
* ''WesternAnimation/MarvelsSpiderMan'':
** When he debuted in ''ComicBook/UltimateSpiderMan'', ComicBook/MilesMorales was 13/14. In the show, he's the same age as Peter.
** Conversely, ComicBook/DoctorOctopus, Alistair Smythe, the Shocker, [[AdaptationalIntelligence the Rhino, and John Jameson]] are reimagined by {{Teen Genius}}es. To a lesser extent, the Vulture is now a middle-aged man like in ''Film/SpiderManHomecoming'', as opposed to an elderly man.
** Played around with ComicBook/AnyaCorazon. Anya is still a teenager like she was in the comics. However, as the show features a Peter who's just starting out as Spider-Man, Anya is now the same age as Peter instead of being younger.
** The Sandman's daughter, Keemia, is a little girl in the comics. In the show, she's a teenager.
* In the 1983 ''WesternAnimation/RainbowBrite,'' Krys was a child Brian's age, but in the 2014 miniseries, he's Brian's father.
* ''WesternAnimation/ChristmasCarolTheMovie'' makes Scrooge middle-aged, while in the book he was elderly.
* ''WesternAnimation/GIJoeRenegades'' sees Dr. Mindbender portrayed as one of the youngest members of Cobra, as opposed to middle-aged like other versions.
* ''WesternAnimation/LesSisters'': In the comics, Maureen was 6 and Wendy was 12. In the animated series, they're both aged up a year, making them 7 and 13 respectively.
* ''WesternAnimation/DuckTales2017'': In the 1987 series, Webby Vanderquack was a little girl and was much younger than Huey, Dewey and Louie. In the reboot, she's the same age as them.
* In ''Anime/{{Voltron}}'', Pidge was a young boy. In the ContinuityReboot, ''WesternAnimation/VoltronLegendaryDefender'', he's now fifteen. [[GenderFlip Oh, and he's a she now]].
** Somewhat downplayed with Coran and Allura. Here, they're [[ReallySevenHundredYearsOld ten thousand years old]] due to [[HumanPopsicle being frozen in cryogenic sleep for millenia]], but are still biologically a teenage girl and a middle-aged man.
* Robin is usually depicted as being somewhere in his early to mid teens, but in ''WesternAnimation/BatmanTheAnimatedSeries'' they put him in college due to the censor's strict guidelines about placing minors in danger, but explain it as he has been under Bruce Wayne's care for some time and is about to go off on his own. Later on, when he becomes Nightwing, they bring in Tim Drake to be Robin, and make him closer to the traditional age.
