->''"Before you go, master, answer me this one, last, big question. Do I grow up to become Creator/AlecGuinness?"''
-->-- ''Series/FrenchAndSaunders'': "The Phantom Millennium"

When a story spans decades, it is often not possible for the one actor to play the same character throughout. Heavy make-up might just let the 30 year old [[PlayingGertrude play 90]], but [[DawsonCasting never 10]]. Instead, multiple actors are used for the same role.

A time-shifted actor will usually be credited as playing 'Young Mr X' or 'Old Ms Y'.

Differentiated from the other [[ActorSwap actor replacement tropes]] by the passage of long stretches of story-internal time. If those long stretches of time have to pass during a short stretch of footage, an AgeCut will allow the actors to be swapped quickly.

This is especially popular in {{prequel}}s and {{sequel}}s, or in stories with a FramingDevice in which 'Old Ms Y' recalls events of her younger days.

Sometimes the necessary resemblance between Mr X and Young Mr X will be achieved by use of a RealLifeRelative. If only a photograph is required, an old picture of the actor/actress will suffice.

* Played for laughs in a Visa check card commercial, where Creator/CharlieSheen waits so long for a store's ID verification that he ages into MartinSheen.
--> '''Store Clerk:''' This doesn't look like you.
--> '''Martin Sheen:''' It did when I came in here....

* While this is averted in the Japanese version (though not completely), several cases occur in the Funimation ''Manga/DragonBall''/''Anime/DragonBallZ'' dub:
** Goku: Stephanie Nadolny → Creator/SeanSchemmel
** Krillin: Laurie Steele → Creator/SonnyStrait
** Gohan: Stephanie Nadolny → Creator/KyleHebert
** Trunks: Creator/LauraBailey → Creator/EricVale
** Goten: Kara Edwards → Creator/RobertMcCollum
** Dende: Creator/LauraBailey → Justin Cook
** Videl: Kara Edwards → Susan Huber
** Pan: Susan Huber → Elise Baughman
** Chi Chi: Creator/LauraBailey → Creator/CynthiaCranz
*** [[LoadsAndLoadsOfCharacters And several others too.]]
* Ranma (from ''Manga/RanmaOneHalf'')'s recast in the dub could be seen as this, considering his voice changes from [[CrossDressingVoice a woman performing a male's voice]] to a male performing a male's voice, and subsequently sounded much older.
* ''OnePiece'':
** Zoro: Creator/BrinaPalencia ([[TheOtherDarrin sometimes Cynthia Cranz or Aaron Dismuke]])→ Creator/ChristopherSabat; Megumi Urawa → Creator/KazuyaNakai
** Sanji: Creator/ChristineAuten → Creator/EricVale; Creator/IkueOtani → Creator/HiroakiHirata
** Like with ''Dragon Ball'', Coby kept the same actor after his growth spurt in the Japanese version, but changed voice actor in the English version: Creator/LeahClark → Creator/MicahSolusod
** In the 4Kids version,
*** Luffy: Tara Jayne → Erica Schroeder
*** Zoro: Creator/AndrewRannells → Creator/MarcDiraison
*** Sanji: Creator/VeronicaTaylor → DavidMoo
* ''Manga/KenichiTheMightiestDisciple'': Originally averted with young Kenichi (with Creator/JoshGrelle voicing the character's younger flashbacks), but on a lengthy flashback, Creator/LeahClark filled in instead.
* For ''Anime/SailorMoon'', most of the Scouts' younger appearances were voiced by their regular voice actors (in both English and Japanese)... except for Darien/Mamoru, who was voiced by a female voice actress in both English and Japanese instead (Creator/MegumiOgata and Julie Lemineax respectively). Ironically, in the Spanish dub, young Darien was voiced by PatriciaAcededo, the Spanish voice of Sailor Moon herself.
* In ''LightNovel/{{Slayers}}'', Lina's younger self in the Naga adventures was voiced by Creator/CynthiaMartinez instead of Creator/LisaOrtiz. While this recast had little to do with the character's age, as the studio also changed, it's interesting that it worked out this way.
* ''Manga/BeetTheVandelBuster'': Beet's voice changed from Creator/TiffanyGrant to Creator/ColleenClinkenbeard after the character grew up. Ironically, both voices were women.
* Averted with ''Anime/TenchiMuyo'', as Tenchi's younger flashback appearances also featured MattMiller as his voice. This is different from the Japanese version, which did cast a female voice actress to handle those scenes.
* ''Manga/{{Bleach}}'': Ichigo Kurosaki is usually Creator/JohnnyYongBosch, but not in his younger flashback appearances, where he's instead voiced by Creator/MonaMarshall.
* Happens with the boys from the Super Peace Busters in ''Anime/AnoHanaTheFlowerWeSawThatDay''. The younger boys are voiced by women (Creator/MutsumiTamura, Creator/AsamiSeto and Creator/AkiToyosaki) and their teenage selves are voiced by men (Creator/MiyuIrino, Creator/TakahiroSakurai and Creator/TakayukiKondo, respectively). The girls are played by the same actresses as kids and teenagers.
* In ''Literature/FromTheNewWorld'', after a time skip of two years, the five main children go from 12 to 14. The boys, Satoru, Mamoru and Shun switch from female actresses to male. Kanako Tojo, Haruka Kudou and Mai Todo voice the 12-year-old versions and Creator/YuukiKaji, Creator/MotokiTakagi, Ayumu Murase voice the 14-year-old versions, respectively. Also the main character Saki Watanabe is voiced by Risa Taneda, although her older self [[spoiler:at 36 years old]] as a narrator is voiced by Creator/AyaEndo.
* In ''Anime/SaintSeiyaOmega'', whenever Kouga (normally voiced by Creator/HikaruMidorikawa) is shown as a young child, he's voiced by Creator/SatsukiYukino, who also happens to voice Yuna.
* ''Anime/TengenToppaGurrenLagann'':
** In both the Japanese and English versions, Simon's voice in the DistantFinale changes from Creator/TetsuyaKakihara[=/=]Creator/YuriLowenthal to [[spoiler:Creator/TakayukiSugo[=/=]Creator/TonyOliver because he was NarratorAllAlong.]]
** In the English version Rossiu's voice actors in the epilogue changes from Creator/JohnnyYongBosch to Creator/MichaelMcConnohie.
** Nia's voice actor in the English version changing from Creator/HyndenWalch to Creator/BridgetHoffman borders between this and TheOtherDarrin: they voiced her before and after a seven-year TimeSkip, but this was just a conveniently-timed coincidence when the former became unavailable, as evident from every other character keeping the same actor.
* While the anime adaptation of ''Manga/JoJosBizarreAdventure'' averted this for some characters between ''Phantom Blood'' and ''Battle Tendency'', ''Stardust Crusaders'' plays this straight with Joseph Joestar, changing from Creator/TomokazuSugita to Creator/UnshoIshizuka.
* This happens with Char Aznable / Casval Rem Deikun in ''Manga/MobileSuitGundamTheOrigin'' where his kid version is voiced by Creator/MayumiTanaka while his teenager and adult self is voiced by Creator/ShuichiIkeda.
* The Latin-American dub of ''Anime/DigimonAdventure02'' recast most of the child actors from ''Anime/DigimonAdventure''. Understandable, seeing as three years have passed in-universe.

[[folder:Films -- Animated]]
* In ''Disney/AtlantisTheLostEmpire'', Kida is voiced by Natalie Strom as a child, but by Creator/CreeSummer as an adult.
* In ''WesternAnimation/{{Balto}}'', Rosy is voiced by Juliette Brewer as child, and played (in a live action sequence) by Creator/MiriamMargolyes (Professor Sprout of the Harry Potter films) as an adult.
* Jason Todd in ''WesternAnimation/BatmanUnderTheRedHood'' is played by three different actors for when the character is a child, a teen and an adult.
* ''Disney/{{Bolt}}'' is an interesting example. Creator/ChloeMoretz originally voiced Penny both as a child and as a teenager. However, Disney wanted another big "name" attached to the film to attract a younger audience, so Music/MileyCyrus was cast... but only as a teenager. Chloe Moretz' dialogue as younger Penny remained in the film.
* In both movie and [[Theatre/TheLionKing musical]] versions of ''Disney/TheLionKing'', Simba and Nala are played by one set of actors as cubs and another as adults.
* Averted in ''WesternAnimation/ToyStory3'' where (the now adult) Andy is actually still voiced by the same actor that played him in ''WesternAnimation/ToyStory'' and ''WesternAnimation/ToyStory2''. Played straight during the film's prologue, however.

[[folder:Films -- Live-Action]]
* Christa B. Allen has played the younger version of Creator/JenniferGarner's character twice, in ''Film/ThirteenGoingOnThirty'' and ''Ghosts Of Girlfriends Past''.
* ''Film/AlmostFamous'' used Michael Angarano as the 9-year-old [[AuthorAvatar William Miller]] for the first 20-odd minutes and Patrick Fugit as his 15-year-old self for the rest of the movie.
* In ''Film/{{Atonement}}'', Briony is portrayed as a child and adult by two newcomer actresses who bear a remarkable resemblance to each other. Then [[OneSceneWonder Vanessa Redgrave]] shows up as the elderly version in the final scene.
* Hilariously inverted in ''Film/AustinPowersInternationalManOfMystery'', when Dr. Evil returns to his lair and his evil organization in 1999 after thirty years of being cryogenically frozen ... [[spoiler: and sees that his wife, Frau Farbissina, looks exactly the same as before.]]
** Played straight in the sequel, where, after traveling back in time, Dr. Evil barely recognizes NumberTwo (portrayed by Creator/RobLowe instead of RobertWagner). Additionally, a flashback in the third film shows young actors portraying Austin, Dr. Evil, and Number Two as teenagers (and toddlers). Interestingly, despite MikeMyers portraying both Austin and Dr. Evil in all films, their teenager versions are portrayed by different actors.
* Averted in ''Franchise/BackToTheFuture'' parts ''[[Film/BackToTheFuture I]]'' & ''[[Film/BackToTheFuturePartII II]]'', each actor played the same characters and used heavy makeup to look the right age for the time period. In one example (Doc Brown) makeup was used for the 1985 Doc to look older, and in Part 2 a futuristic and offscreen medical procedure was used to youthen him...so that he looked like 1955 Doc, eliminating the need for makeup.
* Creator/EwanMcGregor also portrayed young Edward Bloom in ''Film/BigFish'', while Creator/AlbertFinney portrayed old Ed. Reportedly, the decision was made when somebody noticed the resemblance between [=McGregor=] and young Finney. Perry Waltson portrayed Ed as a child.
** The [[http://robertarood.files.wordpress.com/2008/05/tom-jones.jpg resemblance]] ''is'' [[http://www.oceleb.com/img/ewan-mcgregor/ewan-mcgregor-1.jpg remarkable,]] but is pretty much lost on most movie-goers, as they are not familiar with Albert Finney's early work.
* Creator/RichardLinklater's movie ''Film/{{Boyhood}}'' is an aversion to this trope. The movie takes place over 12 years, using the same cast. The catch is that the movie started production in 2002, and was not released until 2014. This means that the actors actually age with their characters.
* ''Film/TheButterflyEffect'' was set around three different periods where the main character is around 8-10, then around 14-16 and finally the present 20 odd. Not only did casting need to find child look-alikes for the main character, but all the other main characters; they did a pretty good job, too.
** But because ViewersAreMorons, the character somehow kept the same haircut throughout all of his life.
* Every production of ''Literature/AChristmasCarol'' needs two young Ebenezer Scrooges, for the Ghost of Christmas Past sequence.
** In the 1951 version, Jacob Marley was played by Creator/PatrickMacnee and Michael Hordern.
** Averted in the Creator/RobertZemeckis version, where through the magic of [[SerkisFolk Performance Capture]], Creator/JimCarrey is able to play Scrooge (and all three ghosts) at all of the requisite ages.
** Also averted in Creator/PatrickStewart's one-man stage version, for obvious reasons.
* ''The Chronicles of Narnia: Literature/TheLionTheWitchAndTheWardrobe'' has a short scene at the end with the grown up Kings and Queens of Narnia. Rachael Henley, Mark Wells, Noah Huntley and Sophie Winkleman play the older versions of the Pevensies, which are played by Georgie Henley, Skandar Keynes, William Moseley and Anna Poppelwell, respectively. Rachael and Georgie Henley, who play the two versions of Lucy, are [[RealLifeRelative real life sisters]].
* ''Film/CitizenKane'', being a fictionalized biopic, presented the title character in all ages. All of them are Creator/OrsonWelles in makeup, except for eight-year-old Kane, played by Buddy Swan.
* In ''Film/TheCuriousCaseOfBenjaminButton'', different actors play Benjamin as he grows younger into his "childhood". Daisy was also played by different actresses as a little girl and a teenager.
* In ''Film/DoctorZhivago'', the eponymous character is played by Omar Sharif. At the beginning of the movie, there is a flashback with the young Yuri. The actor who plays the old Yuri really looks a lot like the actor who plays the young Yuri, because the two are father and son.
* ''Film/ForrestGump'' has Michael Conner Humphreys and Hanna Hall play young Forrest and Jenny. In fact, the story goes that Creator/TomHanks didn't know how he'd voice Forrest until he heard Michael.
* A strange case in ''Gangster No. 1''. Creator/PaulBettany plays the unnamed gangster in the '70s, and Creator/MalcolmMcDowell plays him in modern times, but none of the other characters change actors. Also, Bettany is much taller than [=McDowell=].
* In ''Film/GhostDogTheWayOfTheSamurai'' Creator/ForestWhitaker's younger brother Damon was used as a younger version of the main character during a flashback.
* Averted in ''Film/GhostsOfMississippi'', which takes place over five years (1989-1994). However, neither the protagonist's children nor those of his second wife age one bit.
* ''The Goddess of 1967'', both for the female lead (Bree Beadman is the young version of Creator/RoseByrne) and her mum (Satya Gumbert is the young version of Elise [=McRedie=]).
* ''Film/TheGodfather'' starred Creator/MarlonBrando as the eponymous Vito Corleone, while ''The Godfather Part II'' had Creator/RobertDeNiro as a younger Vito, in flashback sequences. This is particularly notable because both actors received Oscars for the role, the only time the same character has received two awards for different actors. The character also appeared in the same film as a boy, played by yet another actor.
** In the same flashback scenes, the characters of Carmela Corleone, Peter Clemenza and Sal Tessio were all played by younger actors -- as were Sonny, Fredo, Michael and Connie Corleone, who all appeared as babies and young children.
** Michael Corleone's two children were also played by different actors from movie to movie. In fact, the boy who played Anthony Corleone in the second film was the older brother of the boy who played him in the first film.
* Dabbs Greer played the older version of Creator/TomHanks' character in ''Film/TheGreenMile''.
* In ''Film/{{Halloween 1978}}'', Will Sandin portrayed a young Michael Myers at the beginning of the film, while Nick Castle portrayed "The Shape" (older Michael with his mask on), and Tony Moran played an older Michael for the brief scene without his mask.
* In the ''Film/HarryPotter'' film series, Hagrid is played in the present and the prologue of ''Film/HarryPotterAndThePhilosophersStone'' by RobbieColtrane. The young Hagrid in the flashback scenes of ''Film/HarryPotterAndTheChamberOfSecrets'' was played by former rugby player Martin Bayfield, who serves as Coltrane's body double in wide shots of the older Hagrid (Coltrane, however, dubbed the voice of young Hagrid).
** When he regains a body at the end of ''[[Film/HarryPotterAndTheGobletOfFire Goblet of Fire]]'', Lord Voldemort is portrayed by Ralph Fiennes [[note]]in his brief appearance at the end of ''Philosopher's Stone'', [[TheOtherDarrin Ian Hart, Quirrel's actor voices him]][[/note]] As "Tom Riddle", he's played by Hero Fiennes (Ralph's nephew) at age 11 and Christian Coulson (in ''Chamber of Secrets'') and [[TheOtherDarrin Frank Dillane]] (in ''[[Film/HarryPotterAndTheHalfBloodPrince Half-Blood Prince]]'') at age 16.
** Baby Harry Potter was played by the Saunders triplets (first names uncredited) in the first movie and by Toby Papworth in last movie.
** Otherwise, the Harry Potter series represents a notable aversion. When the first movie was made, it was assumed that the child actors would probably need to be recast at some point, but all of the major ones remained for the entirety of the series - nearly a decade in total.
* In ''A Home at the End of the World'', Creator/ColinFarrell's character is played by Andrew Chalmers and Erik Smith, and Dallas Roberts's by Jonathan Glover (no, [[Series/{{Smallville}} not that one]]). Creator/SissySpacek, on the other hand, stays on throughout; eight years isn't that much when you're already over 50.
* In ''Film/IAmSam'', sisters [[Creator/ElleFanning Elle]] and [[Creator/DakotaFanning Dakota]] play Lucy at three and seven, respectively. Elle also plays the younger version of Cate Blanchett in ''Film/TheCuriousCaseOfBenjaminButton''.
** Elle also played a younger version of Dakota's character in one episode of ''Series/{{Taken}}''.
** Dakota did a lot of these roles early in her career. She played a younger version of Calista Flockhart on ''Series/AllyMcBeal'', a younger version of Creator/EllenDeGeneres on ''The Ellen Show'', a younger version of Creator/ReeseWitherspoon in ''Film/SweetHomeAlabama'', voiced a younger version of WesternAnimation/KimPossible in TheMovie, and voiced a younger version of Franchise/WonderWoman on ''WesternAnimation/JusticeLeague''.
* Creator/HaydenPanettiere spends most of ''Film/IfYouBelieve'' as Ally Walker's TimeShiftedActor, as she plays Walker's younger self who comes back to help her out. (She also plays Creator/LaurenBacall's character as a little girl at the start of ''Too Rich: The Secret Life Of Doris Duke''.)
* A VERY unique and artistic version in the film ''Film/ImNotThere'' inspired by the music of of Music/BobDylan. Six actors depict different facets of Dylan's life and public persona: Creator/ChristianBale, Creator/CateBlanchett (yeah, the actress), Marcus Carl Franklin, Creator/RichardGere, Creator/HeathLedger, and Ben Whishaw.
* Creator/HarrisonFord played adult Indiana throughout the ''Franchise/IndianaJones'' film series. Creator/RiverPhoenix portrayed "young Indy" at the beginning of ''Film/IndianaJonesAndTheLastCrusade'' Not enough for you? This spawned ''Series/TheYoungIndianaJonesChronicles'' which featured ''three'' time-shifted Indys: George Hall as the elderly Indy in the framing sequences, Sean Patrick Flanery as [[DawsonCasting 16-19 year old]] Indy for the bulk of the series, and Corey Carrier as 10-year old Indy during the first season. Not to mention Ford reprising the role as a bearded, middle-aged Indy in one episode.
* In ''Film/{{Iris}}'', Creator/KateWinslet played younger version of Iris Murdoch, and Creator/JudiDench played the older version.
* Bobbie Anderson, Jean Gale, Jeanine Anne Roose, Ronnie Ralph, and Georgie Nokes play the child versions of, respectively, George Bailey (Jimmy Stewart), young Mary Hatch (Donna Reed), Violet Bick (Gloria Grahame), Sam Wainwright (Frank Albertson), and Harry Bailey (Todd Karns) in ''Film/ItsAWonderfulLife''.
* ''Truly'' averted in ''Film/TheLimey'' (1999), where the young Creator/TerenceStamp is shown by reusing footage from his earlier movie, ''Poor Cow'' (1967).
* While a child actor had to portray the 10 year old version of title character in ''Film/LittleBigMan'', Creator/DustinHoffman wore make-up to portray the character's centenarian self. He made his voice sound old by going into his dressing room and screaming at the top of his lungs for an hour.
* The 1990s film of ''LittleWomen'' had Creator/KirstenDunst play the younger Amy, and Creator/SamanthaMathis play the older Amy.
* In ''Film/TheLordOfTheRings'' trilogy, Bilbo Baggins is played by Creator/IanHolm, even during the scene in the opening sequence where he obtains the One Ring during the events of ''The Hobbit''. [[Film/TheHobbit The actual films of that particular book]] cast Creator/MartinFreeman in the role.
* Franchise/MarvelCinematicUniverse:
** Creator/DominicCooper plays Young Howard Stark in ''Film/CaptainAmericaTheFirstAvenger'' and ''Series/AgentCarter'' and John Slattery plays Old Howard Stark in ''Film/IronMan2'', ''Film/AntMan'', and ''Film/CaptainAmericaCivilWar''.
** Speaking of ''Ant-Man'', this is PlayedWith in regards to Hank Pym. Creator/MichaelDouglas plays Old Hank Pym for most of the film. In the beginning flashback scene, Creator/DaxGriffin is the body double for Young Hank while Douglas provides the voice and face capture, with the special effects team de-aging his facial features.
** ''Film/GuardiansOfTheGalaxyVol2'' has a similar case with Ego. Creator/KurtRussell plays Ego for the main part of the film, but like ''Ant-Man'', the movie opens with a flashback in which Aaron Schwartz serves as a body double, with Russell providing the voice and facial capture. [[DownplayedTrope Downplayed]] heavily in that Ego is a TimeAbyss.
* In ''Film/MenInBlack3'', present-day Kay is played by Creator/TommyLeeJones. 1969 Kay is played by Creator/JoshBrolin in a notable piece of SeparatedAtBirthCasting.
* ''Film/MissionToMars'' has a brief one of these in a flashback montage. Interestingly, the boy playing Creator/GarySinise's character as a boy was Sinise's own son, [=MacCanna=].
* In the Soviet sci-fi film ''Film/MoscowCassiopeia'', a minor character is first shown as a teenager and then (due to the main characters experiencing TimeDilation) as an adult. They are, obviously, played by different actresses. This serves more to give closure to a minor subplot involving a love letter that she anonymously sent to the boy who would become TheCaptain that she wrote with her off hand in order to hide her handwriting. She admits it was her as an adult.
* ''Film/OnceUponATimeInAmerica'' spanned a few decades and thus had many characters portrayed both as adolescents and adults. Among these were "Noodles" Aaronson played by Scott Tiler and Creator/RobertDeNiro chronologically; and Deborah Gelly played by a young Creator/JenniferConnelly and adult Elizabeth [=McGovern=].
* Creator/HaydenPanettiere played the younger versions of Tess Panzer (Miss Panzer was the grownup version of Sheryl Yoast in the BookEnds of ''Film/RememberTheTitans''), Creator/HilarySwank (''Film/TheAffairOfTheNecklace'') and Emily Watson (''Fireflies In The Garden'').
* Joanne Woodward and Creator/PaulNewman's daughter Nell plays young Rachel in the flashback sequences of ''Film/RachelRachel'', which was directed by Newman and starred Woodward as Rachel.
* ''Film/TheSandlot'' open and closes with an adult Scotty reminiscing about his childhood. (Benny also appears as an adult in the ending sequence, played by [[RealLifeRelative the brother of the actor who played young Benny]].)
* The movie ''Film/{{Serenity}}'' has a flashback of a preteen River in an outdoor classroom setting arguing against the officially-taught premise of the Alliance war on the Independents. She is played by Hunter Ansley Wryn, while the older character in the film's present is played by Creator/SummerGlau. Glau still provides the voiceover for those scenes to make the character connection easier.
* ''Film/TheShawshankRedemption'' features a shot of Red's prison file, complete with mug shots that look like a much younger Creator/MorganFreeman. The actor in the mugshots? One Alfonso Freeman.
* Creator/AnthonyHopkins played Hannibal Lecter in ''Film/SilenceOfTheLambs'', filmed in 1991, and in its prequel ''Film/RedDragon'', which, despite being filmed in 2002, was set in 1980, and managed to pull it off.
* Creator/JimCarrey played "Adult Joe Wenteworth" in the framing sequences of ''Simon Birch'' (the younger version of the character being played by Joseph Mazzello).
* ''Film/StandByMe'' has Creator/WilWheaton as young Gordie Lachance, and Creator/RichardDreyfuss as "[[NostalgicNarrator The Writer]]", the adult Gordie who is writing about his youthful adventures.
* An interesting aversion was done in ''Film/{{Stardust}}'', where Creator/MichellePfeiffer's character goes from old to young and then ages rapidly throughout the film. Instead of using two different actors for the different ages, they used make-up to more accurately portray her aging.
** Played straight with the character of Dunstan, who's first played by [[Film/PrinceCaspian Ben Barnes]] (credited as "Young Dunstan") and then by Creator/NathanielParker.
* ''Franchise/StarTrek''
** ''Film/StarTrekIIITheSearchForSpock''
*** Numerous actors portray Spock as he rapidly re-ages to adulthood. Throw in a scream by yet another (Creator/FrankWelker!) for good measure.
** ''Film/StarTrekVTheFinalFrontier''
*** Creator/JonathanSimpson takes over the role of Sarek from Creator/MarkLenard for the flashback sequences to Spock's birth (and an uncredited infant plays Spock himself)
** ''Film/StarTrek'' (2009)
*** Creator/LeonardNimoy reprised the role of Spock in a TimeTravel-related plot while Creator/ZacharyQuinto plays the role of young Spock, and Creator/JacobKogan played him as a child near the beginning of the film.
*** Creator/ChrisPine played Captain Kirk in the main setting, while Creator/JimmyBennett plays him as a child near the beginning of the film.
* ''Franchise/StarWars''
** The prequels cast Creator/EwanMcGregor as the young version of Obi-Wan Kenobi, a role originated by the late Creator/AlecGuinness. Most of the other characters who appear in the original trilogy, however, are played by the same actors, either because they're voiceover roles or because playing the older version involved heavy makeup that disguises the fact that the actor has aged in the opposite direction from the character. Anakin/Darth Vader has the record for most actors: There's child Anakin (Jake Lloyd), young adult Anakin (Creator/HaydenChristensen), suit Vader (David Prowse in the original trilogy; Hayden Christensen in ''Film/RevengeOfTheSith''; Spencer Wilding in ''Film/RogueOne''), voice Vader (Creator/JamesEarlJones), fencing stunt double, and de-helmeted Vader at the end of ''Film/ReturnOfTheJedi'' (Sebastian Shaw, who also played his Force ghost form later.)
** An unusual [[AvertedTrope aversion]] of the trope: Ian [=McDiarmid=] plays Palpatine in both the original trilogy and in the prequels. He was in his late thirties when he first appeared in ''Film/ReturnOfTheJedi'' but wore makeup to look older; then, by the time ''Film/ThePhantomMenace'' was being made, he had become the right age to play "young" Palpatine. ([[spoiler:He also wears the makeup at the end of the prequels as well: the ''reason'' for the change in his appearance is not the lapse of time but rather a Force-related injury sustained during a duel.]])
** ''Film/TheForceAwakens'': Rey is played at 19 by Creator/DaisyRidley, and as a child by Cailey Fleming during the flashback sequence.
* In ''Film/{{Superman}}'', the teenage Clark Kent is played by Jeff East while the adult counterpart is played by Creator/ChristopherReeve (although Reeve dubbed all of East's lines).
* In the ''Tenacious D'' movie, ''The Pick of Destiny'', amazingly similar-looking child actors are used for young Creator/JackBlack and Kyle Gass.
** The kid who played Creator/JackBlack also played a young version of Black's character in ''Film/NachoLibre''.
* In the movie of ''Film/TheTimeTravellersWife'', the daughter Alba is played at five years old and eight years old by two sisters. This also allowed them to be on screen together.
* ''Film/{{Titanic 1997}}'' had Creator/KateWinslet as Rose in the main storyline, and Gloria Stuart as "Old Rose" in the frame story.
** Interestingly, this is one of only two examples where two separate actors were nominated for Academy Awards for playing the same character in the same film. The other time was ''Film/{{Iris}}'', where Iris Murdoch was played by Creator/JudiDench and...Creator/KateWinslet.
* In TheMovie of ''Film/ToKillAMockingbird'', the voice of Scout as an adult narrator was done by Kim Stanley, while Scout as a child was played by Mary Badham.
* Notably averted in ''Film/TRONLegacy'', where relatively new techniques are used to make Creator/JeffBridges appear much younger than he actually is during the flashback sequences. [[spoiler: Also helps him to portray Clu.]]
* Played with in ''Film/WalkHard''. While a young Dewey Cox is portrayed by a child actor, Creator/JohnCReilly plays him all the way from age 14 into Dewey's 70's, and Dewey's first wife is played by the same actress (in her thirties) from age 12 to her elder years. This is played for comedy.
* ''Film/{{Watchmen}}'' tried to avert this to the best of their ability by casting young and then aging up. This meant that Creator/CarlaGugino and Creator/JefferyDeanMorgan spent most of their screentime under heavy makeup.
* In ''Literature/WaterForElephants'', the younger version of Jacob is played by Creator/RobertPattinson, and the older version who appears in the present to set up a framing device for the story ala ''Titanic'' is played by Hal Holbrook.
* Creator/ArielWinter has been the little-girl versions of Michelle Monaghan (''Film/KissKissBangBang'') and Creator/VictoriaRicci (''Film/SpeedRacer'').
* ''Film/XMenFilmSeries'':
** ''Film/XMen1'': Played straight in the opening with the young Erik Lehnsherr, who later becomes Magneto (Sir Creator/IanMcKellen's character) in the present.
** ''Film/XMenTheLastStand'': Averted with Creator/PatrickStewart and Creator/IanMcKellen because they play their characters' younger selves through digital effects. This was also used for Stewart's brief scene in ''Film/XMenOriginsWolverine''.
** ''Film/XMenFirstClass'': There's a FlashbackWithTheOtherDarrin with the new young Erik. Creator/JamesMcAvoy and Creator/MichaelFassbender take over from Patrick Stewart and Ian [=McKellen=] as the young [[Characters/XMenFilmSeriesProfessorCharlesXavier Charles Xavier]] and [[Characters/XMenFilmSeriesMagneto Magneto]]. The young [[Characters/XMenFilmSeriesMystique Mystique]] is played by Creator/JenniferLawrence, taking over from Rebecca Romijin. Creator/NicholasHoult takes over from Creator/KelseyGrammer as the young Beast, and Creator/RoseByrne takes over from Olivia Williams as Moira [=MacTaggert=].
** ''Film/XMenDaysOfFuturePast'': Creator/JamesMcAvoy and Creator/MichaelFassbender return as the young versions of Professor X and Magneto, while Creator/PatrickStewart and Creator/IanMcKellen portray them in the BadFuture segments of the movie. Creator/JenniferLawrence once again plays the young Mystique. Josh Helman plays young William Stryker, replacing Danny Huston as [[Film/XMenOriginsWolverine middle-aged Stryker]] and Creator/BrianCox as [[Film/X2XMenUnited old Stryker]]. Evan Jonigkeit portrays a young version of Toad (played as an adult by Creator/RayPark in the [[Film/XMen1 original movie]]), and [[spoiler: Creator/NicholasHoult returns as the young Beast, while Creator/KelseyGrammer reprises his role in the surprise EveryoneLives ending set in the future]].
** ''Film/XMenApocalypse'': Creator/TyeSheridan, Creator/SophieTurner, Alexandra Shipp and Kodi Smit-[=McPhee=] portray teenage versions of ComicBook/{{Cyclops}}, Comicbook/JeanGrey, Comicbook/{{Storm}} and Nightcrawler respectively, who were played as adults by Creator/JamesMarsden, Creator/FamkeJanssen, Creator/HalleBerry and Creator/AlanCumming in the original trilogy.

[[folder:Live-Action TV]]
* ''Radio/OurMissBrooks'': "The Dream" features older versions of Mr. Conklin, Walter Denton, Mrs. Davis, Mr. Boynton and Mrs. Boynton nee Brooks played by series regulars Gale Gordon, Richard Crenna, Jane Morgan, Robert Rockwell and Eve Arden respectively.
* ''Series/AmericanHorrorStory'' generally avoids this trope, preferring to age actors up or down when needed by using makeup and FX, but they have used it a couple of times, specifically when older actors needed to be aged down drastically rather than by a decade or two:
** Dr. Arden/Hans Gruber, who first appeared in ''Asylum'' but later returned in ''Freak Show'' as one of the series' first recurring characters, is played by Creator/JamesCromwell for the most part, but by his son John Cromwell in flashbacks to his youth (notably, this encompasses all the character's scenes in ''Freak Show'').
** In ''Coven'', Fiona and Myrtle are played by series regulars Creator/JessicaLange and Frances Conroy, respectively. However, since both those ladies are in their sixties, younger actresses were used to portray them as teenagers in flashbacks: Riley Voelkel as Young Fiona, Michelle Page as Young Myrtle. Amusingly, they don't do the same for the coven's servant Spalding, who is played by Denis O'Hare in both time frames.
* The flashback-heavy series ''Series/ArrestedDevelopment'' used this all the time for the Bluth kids, but the George and Lucille were usually the regular actors. In Season 4, flashbacks had Seth Rogen and Kristen Wiig as the younger George and Lucille.
* Patrick Dennis in ''Literature/AuntieMame'' and its musicalization ''Mame''.
* ''Series/{{Blossom}}'' made good use of Joey Lawrence's real life brothers for a flashback episode or two.
* ''Series/BuffyTheVampireSlayer'' did it three times, with a young actress playing Buffy as a girl. It was a different actress each time. Mimi Paley in "[[{{Recap/BuffyTheVampireSlayerS2E18KilledByDeath}} Killed By Death]]", Alexandra Lee in "[[{{Recap/BuffyTheVampireSlayerS5E21WeightOfTheWorld}} Weight of the World]]" and Candice Nicole in "[[{{Recap/BuffyTheVampireSlayerS5E13BloodTies}} Blood Ties]]" presumably due to age considerations.
** ''Series/{{Angel}}'' did it, understandably, with Connor after his PlotRelevantAgeUp.
* Creator/TheBBC miniseries ''Series/{{Casanova}}'' cast Creator/DavidTennant as the young Casanova, Creator/PeterOToole as the old Casanova and John Sandilands and Zachary Fox as Casonova as a child.
** James Holly, Brock Everett Elwick and Tom Burke played Casanova's son at different parts of his life.
** Leonilda appeared as a baby, and at age 20 played by Naomi Bentley.
* ''Series/{{Centennial}}'' used makeup to show most characters aging, outside of brief, non speaking childhood scenes. However, the character of Jim Lloyd was portrayed by Michael LeClair as a 16 year old and Creator/WilliamAtherton as an adult. Also seen with the characters of the two Pasquinel brothers and Philip Wendell. In the latter case, it was the childhood version, played by Doug McKeon, who had the larger role in comparison with the adult, played by Morgan Paull.
* ''Series/{{Charmed}}'''s fourth season episode "[[{{Recap/CharmedS4E14TheThreeFacesOfPhoebe}} The Three Faces of Phoebe]]" featured her bringing her past and future selves into the present with her which were both played by different actresses. In the finale "[[{{Recap/CharmedS8E22ForeverCharmed}} Forever Charmed]]" this is done with Piper as well, though the child form of her does not appear on screen with the adults.
** Done even earlier in Season 1's "That '70s Episode," in which a time travel spell sends the sisters back to when Prue and Piper were children.
* ''Series/ColdCase'' uses this extensively, as its stories are told mostly in flashbacks from cases spanning the gamut of 1 to 100 years in the past.
** A few early episodes attempted do to this through make-up rather than casting different actors. The results were not very convincing.
* Similarly, in the 1998 miniseries of ''Literature/TheCountOfMonteCristo'', starring Creator/GerardDepardieu, the protagonist was played in the prologue by Guillaume Depardieu.
* ''Series/{{CSINY}}'' did this during a flashback in one of the "333" arc episodes, with a teen actor playing young Mac.
* ''Series/{{CSI}}'' did a similar thing with a childhood flashback Catherine had.
* Four actors have played the eponymous character in ''Series/{{Dexter}}'' in flashback scenes, including star Michael C. Hall.
* ''Series/DoctorWho'':
** In [[Recap/DoctorWhoS3E4TheDaleksMasterPlan "The Daleks' Master Plan"]], Sara Kingdom gets aged to death by the Time Destructor. Jean Marsh's mid-stage ageing is created with extensive makeup but the fully-aged version of her is played by May Warden.
** In [[Recap/DoctorWhoS9E5TheTimeMonster "The Time Monster"]], Benton is regressed by a time-manipulating alien goddess into an uncredited baby. Sadly, the baby 'actor' died before his first birthday, as John Levine points out on the commentary track.
** Creator/ElisabethSladen appears over three Franchise/{{Whoniverse}} TV shows, and [[AudioPlay/SarahJaneSmith a Big Finish-produced audio spinoff]] over 38 years as Sarah Jane Smith. In ''Series/TheSarahJaneAdventures'', she's played by an uncredited baby as a child, Jessica Mogridge as a child in flashback and Jessica Ashworth at age 13.
** An uncredited extra plays the youthful Maren in [[Recap/DoctorWhoS13E5TheBrainOfMorbius "The Brain of Morbius"]], which is odd as the elderly Maren was played by Cynthia Grenville, a young woman in very heavy age makeup which they could easily enough have removed.
** We meet Rose Tyler as an uncredited baby and as a child played by Julia Joyce in [[Recap/DoctorWhoS27E8FathersDay "Father's Day"]], and at age 19 by Creator/BilliePiper. Also in "Father's Day", Mickey Smith is played by Casey Dyer, while as an adult he's played by Creator/NoelClarke. The same episode, however, contains a bizarre aversion -- 20-year-old Jackie Tyler is played by the same (barely under 40) actress who plays her present-day self, and no effort is made to make her look any younger.
** Companion Jack Harkness is played by Creator/JohnBarrowman as an adult, and in the ''Series/{{Torchwood}}'' episode "[[{{Recap/TorchwoodS2E5Adam}} Adam]]" by Jack Montgomery as a child.
** In [[Recap/DoctorWhoS28E4TheGirlInTheFireplace "The Girl in the Fireplace"]], Reinette is played by Jessica Atkins as a child, and Creator/SophiaMyles for the rest of her life.
** Queen Elizabeth I is played by Angela Pleasence in her later years ([[Recap/DoctorWhoS29E2TheShakespeareCode "The Shakespeare Code"]]), and Joanna Page as a young woman ([[Recap/DoctorWho50thASTheDayOfTheDoctor "The Day of the Doctor"]]).
** In [[Recap/DoctorWhoS29E8HumanNature "Human Nature"]]/[[Recap/DoctorWhoS29E9TheFamilyOfBlood "The Family of Blood"]], Tim Latimer is played by Thomas Sangster as a teenager, and an uncredited Huw Rees as an elderly man.
** The episode [[Recap/DoctorWhoS29E10Blink "Blink"]] has an unusual example in which the character of Billy Shipton is played as a young man by Michael Obiora, then minutes later he appears as an old man portrayed by Louis Mahoney. The character had been [[spoiler:sent back 38 years in time and lived out the loop to the present in order to give a message to Sally Sparrow, the protagonist of the story]].
** [[Recap/DoctorWhoS29E12TheSoundOfDrums "The Sound of Drums"]] introduces us to William Hughes (uncredited), portraying the Master as a child. Interestingly, this makes him the first Master, chronologically speaking.
** In [[Recap/DoctorWhoS30E7TheUnicornAndTheWasp "The Unicorn and the Wasp"]], Lady Eddison is played by Felicity Kendal in 1926 and an uncredited woman 40 years earlier.
** [[Recap/DoctorWhoS30E16TheWatersOfMars "The Waters of Mars"]]:One-off companion Adelaide Brooke is played by Rachel Fewell as a child, and Lindsay Duncan as an adult.
** In the episodes [[Recap/DoctorWhoS31E1TheEleventhHour "The Eleventh Hour"]] and [[Recap/DoctorWhoS31E13TheBigBang "The Big Bang"]], as well as flashbacks in [[Recap/DoctorWhoS32E8LetsKillHitler "Let's Kill Hitler"]], Amy Pond is played as a seven-year-old by Creator/CaitlinBlackwood before being played as an adult by Creator/KarenGillan. The two actresses are cousins. Also in "Let's Kill Hitler", a young Rory is played by Ezekiel Wigglesworth, while he's played as an adult by Creator/ArthurDarvill.
** Creator/MichaelGambon plays the miserly Kazran Sardick in the episode [[Recap/DoctorWho2010CSAChristmasCarol "A Christmas Carol"]]; his younger self is initially played by Laurence Belcher, then becomes a teenager as Danny Horn. (Then [[spoiler: back to Belcher to get "shown his future"]]).
** In [[Recap/DoctorWhoS32E1TheImpossibleAstronaut "The Impossible Astronaut"]], Canton Everett Delaware III is initially played by William Morgan Sheppard, before the TARDIS crew travel back in time to meet him played by Sheppard's son, Creator/MarkSheppard.
** In "Let's Kill Hitler", Amy and Rory's childhood friend Mels, [[spoiler:in actuality River Song before she regenerated into Creator/AlexKingston's incarnation]], is played by Maya Glace-Green as a kid and Nina Toussaint-White in the present. In "A Good Man Goes to War", [[spoiler:River, then called Melody and in an even earlier incarnation is played by twins Harrison and Madison Mortimer]], while in the opening two-parter "The Impossible Astronaut"/"Day of the Moon", [[spoiler:she's slightly older and played by Sydney Wade]].
** [[Recap/DoctorWhoS34E4Listen "Listen"]] features Samuel Anderson playing Danny Pink's IdenticalGrandson, and Remi Gooding playing a child Danny Pink. There is also an uncredited child playing a young [[spoiler: First Doctor]].
** Aversions:
*** [[Recap/DoctorWhoS18E1TheLeisureHive "The Leisure Hive"]]: Creator/TomBaker plays the Doctor (by then in his late 40s and looking arguably older due to illness), the Doctor aged 500 years by AppliedPhlebotinum (appearing to be in his 80s), and multiple youthful clones of the Doctor (appearing to be in their late 20s-early 30s). Heavy makeup and some lighting and acting tricks were used to accomplish this. [[note]]This whole sequence was something of an ActorAllusion - Tom Baker's most famous role before playing the Doctor was a wizard in ''Film/TheGoldenVoyageOfSinbad'' whose age fluctuated from late 20s to late 80s due to CastFromLifespan powers.[[/note]]
*** [[Recap/DoctorWhoS29E6TheLazarusExperiment "The Lazarus Experiment"]] sees Creator/MarkGatiss play both the young and old Professor Lazarus, the old version under heavy makeup to the point of being almost unrecognizable.
*** "The Sound of Drums"/[[Recap/DoctorWhoS29E13LastOfTheTimeLords "Last of the Time Lords"]]: The Doctor is forcefully aged by the Master. He is still played by Creator/DavidTennant, but again under extensive makeup. A more severely-aged version is [[SerkisFolk played by CGI with Tennant dubbing the voice]].
*** The final moments of [[Recap/DoctorWho50thPrequelTheNightOfTheDoctor "The Night of the Doctor"]] used a genuine photograph of Creator/JohnHurt as a young actor to create a reflected image of the newly-regenerated War Doctor.
*** [[Recap/DoctorWho2013CSTheTimeOfTheDoctor "The Time of the Doctor"]] features Matt Smith playing the Eleventh Doctor in various stages of ageing.
* In ''Series/TheSarahJaneAdventures'', Rani Chandra is played by Anjli Mohindra as a teen, and Souad Faress as the Mad Old Woman of Bannerman Road in the story ''The Mad Woman in the Attic''.
* In ''Series/{{Torchwood}}'', Jack's brother Gray is played by Ethan Brooke as a child and Lachlan Nieboer as an adult.
** In a flashback in ''Children of Earth'', young [=Clem MacDonald=] is played by Gregory Ferguson. As an adult, he's played by Paul Copley.
** In a ''Series/TorchwoodMiracleDay'' flashback, [[spoiler:Jack's past lover Angelo is played by Daniele Favili as a young man, and an uncredited actor as an old man the following episode]].
** The Quantum transducer showed flashbacks of several people in the considerable past in the episode "[[{{Recap/TorchwoodS1E3GhostMachine}} Ghost Machine]]".
** In "[[{{Recap/TorchwoodS1E9RandomShoes}} Random Shoes]]", Eugene Jones is played by Luke Bromley in 1992 and Paul Chequer in 2007.
** The memory alterer Adam Smith from the episode "Adam" is mostly played by Bryan Dick. When he forces himself into the memories of Jack's childhood, he's played by Rhys Meyers.
* Season 2 of ''Series/{{Fargo}}'' acts as a prequel to Season 1 taking place nearly thirty years previously, with three characters carried over. Molly Solverson, the protagonist of the first season played by Alison Tolman, appears as a little girl played by Raven Stewart. Meanwhile, her father Lou, a semi-retiree in his 60s played by Creator/KeithCarradine in the first season, is now the thirty-something protagonist, being played by Patrick Wilson. There's a secondary character carried over in the form of Ben Schmidt, Gus's boss from the first season (where he was played by Peter Breitmayer), whom Lou ends up rather reluctantly working with in the second (where he's now played by Keir O'Donnell).
* Zac Efron played the young Simon Tam in a ''{{Series/Firefly}}'' flashback.
* The 1990s young adult series ''Series/FlashForward'' often intersperses home video clips of five-year-old Tucker and Becca (who are also featured in the opening credits) into the plot. The characters are 14 years old when most of the action takes place.
* The ''Series/FrenchAndSaunders'' parody of ''Franchise/StarWars (The Phantom Millenium)'' naturally lampshades this, with Toby-Jugs Kenobi very keen to know if she'll grow up to become Creator/AlecGuinness.
* An episode of ''Series/TheFreshPrinceOfBelAir'' had a flashback to before the Banks became rich, in which every major character excluding Ashley, who wasn't born at the time of the flashback, were played by different actors. However, in a later episode where the cast are watching an old video tape of Vivian and Phil, they are played by the same actors. Which is bizarre when you think about it, as this footage was supposed to have been before the children were even born, and therefore Phil and Vivian would have been younger than in the previous flashback where they were played by younger actors.
* On ''Series/FullHouse'' young Danny was played by Phillip Glasser, whose other claim to fame is voicing Fievel in ''WesternAnimation/AnAmericanTail''.
* ''Series/GameOfThrones'':
** Hodor has a different actor for flashbacks in Season 6.
** Rodrik Cassel also has a different actor for flashbacks in Season 6 (note that Fergus Leathem/Young Rodrik looks a lot like Podrick Payne actor Daniel Portman is Ron Donachie's son in real life, so logically Daniel looks like young Ron).
** Old Nan has a different actress for flashbacks in Season 6.
** Robert Aramayo played the young adult version of Ned Stark in Season 6 flashbacks instead of Creator/SeanBean.
* Adam Kolkin plays a younger Kurt in ''Series/{{Glee}}'', bearing [[http://blogs.ocweekly.com/navelgazing/Adam-Kolkin_Chris-Colfer_Kolkin-Family.jpg such an impossible resemblance to Chris Colfer]] that many people were convinced that the flashbacks had been done using technology, or at the very least that the two were related in some way. They aren't.
* ''Series/TheGoldenGirls'' had occasional flashbacks to when Dorothy was a young adult. The casting director did a good job of finding an actress who looked like a younger version of Bea Arthur's character (Creator/EstelleGetty was simply able to take off the white wig and age makeup for her scenes).
** An older flashback featured Sophia's mother, played by none other than Creator/BeaArthur.
* A couple of episodes of ''Series/GoodEats'' feature Young Alton, played by John Herina, the same actor who plays his nephew in other episodes. They're not actually related, but Elton (the nephew) does have a shocking resemblance to his "uncle".
* ''Series/{{Highlander}}'' "The Prophecy"-young actor as the boy Duncan Macleod subbing in for Adrian Paul who played adult Duncan.
* On ''Series/HowIMetYourMother'', Josh Radnor plays "present day" Ted, while Bob Saget is the voice of "future" Ted. Every time we've seen flash-forwards of Ted in the future, however, he's played by Radnor in makeup.
* ''Series/ICarly'' had a young Sam and young Carly for a flashback.
** Creator/MirandaCosgrove, who plays the regular Carly, was a 'young' Lana Lang on ''Series/{{Smallville}}''. Making her someone who has been both a younger version of a main character, and had a younger version of one of her main character.
* In ''Series/KungFu'''s OnceAnEpisode flashbacks young Kwai Chang Caine was played by Radames Perá. In the occasional flashback to teenage Caine, he's played by star David Carradine's younger brother Keith, with David usually (but not always) providing the voice.
** In ''Kung Fu: The Legend Continues'' young(er) but adult Kwai Chang Caine was played by David Carradine and Peter Caine (his son) was played by Nathaniel Moreau (and later Robert Bedarski).
* ''[[Series/LoisAndClark Lois and Clark: The New Adventures of Superman]]''
** A time-traveling [[Creator/HGWells H. G. Wells]] was a recurring character. One actor portrayed him in season 2, another in season 3, and then both portrayed him in different episodes of season 4. The difference was explained by one being an older (by sixteen years) incarnation of the other.
** Jimmy Olsen gets hit by an aging ray in the episode "Brutal Youth". Rather brilliantly, his aged self is played by Jack Larson, who [[RemakeCameo previously played Jimmy]] in ''Series/TheAdventuresOfSuperman''.
* ''Series/{{Lost}}'' has needed these occasionally due to its flashback structure.\\
We've seen Jack, Sun, Locke, Ben, Charlie, Sawyer, Eko, Faraday, Sayid, Kate, Hurley, Yemi, Juliet, Rachel Carlson, Alex, [[spoiler:Jacob]] and [[spoiler:the Man in Black]] as children in flashbacks. Locke, Ben, Alex, [[spoiler:Jacob]] and [[spoiler:the Man in Black]] have also been depicted as newborns. "Cabin Fever" saw Locke as an infant, a child, a teenager, and an adult.\\
Walt was already a 10-year-old child during seasons 1 and 2, but also appeared as an infant in the season 2 episode "Adrift". However, the season 2 episode "One of Them" averted this by using an actual photo of a teenage Evangeline Lilly (Kate) for a flashback scene where her character's father is looking at a photo of his daughter. Emily Locke appeared as an adult and as a teenager when she was pregnant with John.
** Due to time travel, ''Lost'' showed younger versions of characters in its fifth season without explicitly revealing who they were as a form of a twist. A younger [[spoiler: Charles Widmore]] (two, one in [[spoiler:1954]] and one in [[spoiler:1977]]), [[spoiler: Danielle Rousseau when she was shipwrecked in 1988]], [[spoiler: Eloise Hawking]] (again, two, in [[spoiler:1954 and 1977]]) and [[spoiler:Charlotte Lewis]] (in [[spoiler:1974]] and [[spoiler:1977]]) appeared that year. The actress who played [[spoiler:1977 Eloise]] also appears in a flashback with Daniel Faraday the same episode that era's [[spoiler:Eloise]] first appeared.
** In the second half of the show, after pre-Island flashbacks were mostly gone, [[spoiler:Aaron, Ji Yeon and Desmond's son Charlie]] appeared as newborns around 2004/05 (in-story) and as toddlers in 2007. Similarly, Clementine Phillips was shown as a baby photograph in a pre-Island flashback and as a child in 2007.
** In season 5, Ethan and Miles appeared during the islanders' time travelling as babies [[spoiler:in 1977]] and as children in flashbacks (Ethan's while [[spoiler:Alex was a baby around 1988]]).
* ''Series/MalcolmInTheMiddle'' had disturbingly similar-looking actors for the younger versions of the cast in the flashback episodes.
** Amusingly, by the final episode, the flashback actors were about the same ages as the main cast had been in the first season.
* ''Series/{{Merlin}}'' had Mordred played by twelve-year-old Asa Butterfield in the first two series, after which he was PutOnABus and not seen again until series 5, seven years later due to a TimeSkip, where he's now played by twenty-three-year-old Alexander Vlahos.
* In ''Series/MightyMorphinPowerRangers'', Season 2's "Rangers Back in Time" two-parter saw Lord Zedd turn back time. The six Ranger teens (as well as Bulk and Skull) became children with age-appropriate actors, though the school principal and their teacher were played by the same people. Master Vile tried the same trick for the final arc of Season 3, with the child actors being brought back (except for young Kimberly's, as Katherine had joined up by then). As the arc was resolved in a two-parter of its own, a young Tanya was introduced before her teenaged self appeared.
** In the ''Power Rangers Zeo'' two part episode, Rangers of Two Worlds, Billy was the victim of accelerated aging, and was played by an older actor. The in universe explanation was due to Billy being re-aged after the Master Vile situation. The real world reason was David Yost leaving the show because of off-camera gay bashing he was the target of.
* The 2011 mini-series version of ''Series/MildredPierce'' had Morgan Turner as Veda in her preteen and early teenage years (through age 14-15), and Creator/EvanRachelWood as Veda in her late teens and early twenties.
* ''Series/MyNameIsEarl'' has had flashbacks to the title character's childhood using appropriately-aged actors.
* In the Season 7 finale of TV's ''Series/MysteryScienceTheater3000'', Dr. Forrester experiences rapid aging as part of an extended ''2001'' reference. Old!Forrester was played by Jack Beaulieu, Trace Beaulieu's father.
* William Morgan Sheppard and Creator/MarkSheppard, mentioned above under ''Series/DoctorWho'', also appeared as older and younger versions of the same character in an episode of ''Series/{{NCIS}}''.
* In ''Series/OnceUponATime'':
** In the episode "Stable Boy", the fairytale world plot flashed back to when the teenage Regina (still played by Lana Parilla) met Snow White and her father. Child Snow was played by Bailee Madison, who could easily pass for (adult Snow) Ginnifer Goodwin's daughter or young sister.
** Regina's mother, Cora, is played by Barbara Hershey as a middle-aged and older woman in the show's present and in flashbacks with Regina as a young woman, and by Creator/RoseMcGowan as a late-teens or early-twenties woman (DawsonCasting, as [=McGowan=] was in her late thirties at the time) in a few episodes with flashback sections to her early life.
* In a non-time example, ''Series/OrangeIsTheNewBlack'' has Laverne Cox play Sophia, while her twin brother plays her before her sex change.
* ''Series/ThePretender'' uses this trope with most of its main cast. There are three different actors for Jarod (child, teen, adult), and two for Sydney, Miss Parker, and Angelo.
** And [[spoiler: they spun young Jarod off as a clone.]]
* Every episode of ''Series/{{Psych}}'' also begins with a flashback, with younger actors playing Shawn and Gus. However, Corbin Bernsen, who plays Shawn's father, just wears makeup and [[HairTodayGoneTomorrow a hairpiece]] to make him look younger. We get a LampshadeHanging, of course.
* In ''Series/PushingDaisies'', two of the main characters are Ned (played by Lee Pace) and Chuck (played by Anna Friel). However, every episode opens with a flashback to Ned's childhood, where Ned and Chuck are played by Field Cate and Sammi Hanratty, respectively. Olive (Kristin Chenoweth), Emerson (Chi [=McBride=]) and Lily (Swoosie Kurtz)also got a flashback each in season 2, in which they were played by Samantha Bailey, Stephen Wash, Jr. and [[Series/TerminatorTheSarahConnorChronicles Mackenzie Brooke Smith]], respectively.
* All the major non-AI characters of ''Series/RedDwarf'' have have had childhood versions of themselves played by different actors.
** Adult Rimmer is played by Chris Barrie. Young Rimmer appeared in three episodes, played by Simon Gaffney. A teenage Rimmer in the series X episode, "The Beginning", was played by Philip Labey.
** (Initially) 20-something Lister is played by Craig Charles. Lister has appeared as a teenager (played by Charles' younger brother Emile), and as a baby (played by Danny John-Jules' real-life nephew Alexander).
** Lister, Cat and Kochanski have all appeared as young children when briefly de-aged, played respectively by an uncredited actor, Perri Michael and Holly Earl. Lister has also been turned into an old man, also played by an uncredited actor.
* In the 1996 MiniSeries ''Rhodes'', Cecil Rhodes was played by Creator/MartinShaw and "Young Cecil Rhodes" was played by Shaw's son, Joe Shaw.
* In ''Series/{{Rome}}'', Gaius Octavian is played by Max Pirkis as a teenager and Simon Woods as an adult. The change happens while he goes to war. Upon seeing the adult Octavian for the first time, his mother makes a remarks about military rations having made an effect on him. The trope is bizarrely averted, however, with Vorenus's children, who should be in their thirties by the final episode. One is played by the same actress who played her as a fourteen-year-old, the other two are played by actors who are at most twelve.
* The mini-series ''Series/{{Roots}}'' cast Levar Burton as teenaged Kunta Kinte and John Amos as an adult. For most other characters, heavy makeup was used to show them aging.
* ''Series/{{Smallville}}'' had Victoria Duffield and Jackson Warris playing the young versions of Chloe Sullivan and Clark Kent.
* In the ''Series/StargateSG1'' episode "1969", General George Hammond is normally played by the late Creator/DonSDavis. After traveling back in time, they meet Lieutenant George Hammond played by Aaron Pearl. Also, in the episode "Fragile Balance", [[RichardDeanAnderson Jack]]'s teenage clone is portrayed by Michael Welch.
** Others include Linea (Bonnie Bartlett as old, Megan Leitch as young), Dr. Ernest Littlefield (Keene Curtis as old, Carson Be... sorry, Paul McGillion as young), Orlin (Sean Patrick Flanery as adult, Cameron Bright as child), Cassandra Frasier (Katie Stuart as child, en Rennison as teenager, Pamela Perry as old)
** Catherine Langford takes the prize with ''five'' actresses. First, there are the two portraying her in the original film (Kelly Vint as child, Viveca Lindfors as adult). Then there are the actresses from the show (Nancy McClure as young circa 1945, Glynis Davies as adult in 1969, Elizabeth Hoffman as primary appearance).
** Because Adria grows from infancy to adulthood in a matter of days, the premiere episode of season 10 has four different actresses play the part first as a newborn, then at ages 4, 7, and 12.
* ''Franchise/StarTrek'':
** ''Series/StarTrekTheNextGeneration'':
*** "Firstborn" had an older Alexander (Worf's young son) played by James Sloyan.
*** Child versions of Picard, Keiko, Guinan, and Ro appear in "[[{{Recap/StarTrekTheNextGenerationS6E7Rascals}} Rascals]]", though it is not a flashback. The person who played young Guinan also played Creator/WhoopiGoldberg's character as a child in ''Film/SisterAct''. The actor who played young Picard earlier played Picard's nephew Rene in "[[{{Recap/StarTrekTheNextGenerationS4E2Family}} Family]]".
*** Played straight at first in "Tapestry", as Marcus Nash plays young Picard when he sees himself getting stabbed, but then averted when Creator/PatrickStewart plays young Picard for the rest of the episode.
** ''Series/StarTrekDeepSpaceNine'': "The Visitor", which was a FlashForward episode, had then-teenage Jake Sisko (normally played by Cirroc Lofton) played by Tony Todd. That and SoapOperaRapidAgingSyndrome results in four different Alexanders.
* In episode of ''Series/{{Supernatural}}'' with flashbacks to Sam and Dean's pasts, the younger Sam was played first by Alex Ferris and then [[WesternAnimation/JakeAndTheNeverLandPirates Colin Ford]] while Dean was played by Ridge Canipe as a child and by Brock Kelly.
** In two time-travel episodes the younger John and Mary Winchester were respectively played by Matt Cohen and Amy Gumenick rather than Jeffrey Dean Morgan and Samantha Smith.
* The Sci-Fi Channel Original Series ''Series/{{Taken}}'' spans three generations of families, with the characters in the families being played, mostly, by age-specific actors.
* The TV adaptation of ''Literature/TheThirteenthTale'' features three.
** Vida Winter is played by four actresses: Creator/VanessaRedgrave as an old woman, Creator/SophieTurner as a young woman, Madeleine Power as a pre-teen, and Maggie Waller as an even younger child.
** Emmeline March is played by Antonia Clarke as a young woman and Madeleine Power ([[PlayingTheirOwnTwin again]]) as a pre-teen.
** Margaret Lea is played by Olivia Colman as an adult and Isabel Barlow as a child.
* In ''Series/ThisIsUs'', the Pearson triplets are played by three different sets of actors for each decade: the present day adults, 1990s teenagers, and 1980s children.
* One set of ''Series/TopGear'' teasers featured (incredibly well-cast) child versions of the three hosts musing about what they'd do when they grew up, as well as commenting on "the new kid" - mini-The Stig driving a red wagon (aww!).
* In the Russian mini-series ''Wolf Messing: Seeing through time'', the titular character (loosely based on the RealLife self-proclaimed psychic of that name) is played by three actors: Aleksandr Hinkis as a boy, Roman Grechishkin as a young man (voiced by Stanislav Bondarenko), and Yevgeniy Knyazev as an adult (the majority of the series including the ColdOpen).
* This played with a twist in ''Series/{{Westworld}}''. William is played by Creator/JimmiSimpson while his older self [[spoiler:is The Man in Black himself played by Creator/EdHarris]].
* ''Series/TheWonderYears'' features an adult narrator, and his childhood self the main protagonist.
** ''Series/EverybodyHatesChris'' [[FollowTheLeader does the same]].

* In the video to "The Miracle", the members of Music/{{Queen}} are played by kids.
* In ''Film/{{Moonwalker}}'', the same actor played young Music/MichaelJackson in a sequence that parodies "Bad" and later played him in "The Jacksons: An American Dream."
* The Music/SpiceGirls video for "Mama" has child actors playing the girls intercut with pictures of the real girls as children.
* The video for Music/{{Van Halen}}'s "Hot For Teacher" had kids playing younger versions of the band members.

[[folder: Radio]]
* In Creator/TheBBC radio adaptation of ''Literature/TheOnceAndFutureKing'', Paul Ready plays Arthur and Paul Heath plays Sir Kay. Edward Bracy plays Wart and Ethan Hammer plays Young Kay.

* In ''Theatre/{{Follies}}'', the four middle-aged main characters all have younger doubles, who appear in the very frequent {{flashback}}s. Many secondary characters also have younger doubles who mimic their dance steps.
* The musical ''Theatre/LesMiserables'' requires a child to play young Cosette (whose face is on the poster) and a young lady to play adult Cosette. Young Eponine has a walk on role just after the "Castle on a Cloud" number, and grown-up Eponine becomes a major character a few songs later.
** Notably, the two young actresses alternate between these roles.
** The twenty-plus-year run of the show means there has been at least one case of an actress who played Young Cosette as a child returning to play grown-up Eponine.
** Similarly, Creator/LeaSalonga played Eponine on Broadway in 1993 and then sang the part of Fantine at the Twenty-Fifth Anniversary Concert.
* In the musical ''Gypsy'', two child actresses play Baby June and Baby Louise at the opening of the show, only to grow up (with help from some strobe lights) into the adult actresses who play Dainty June and Louise.
** Presumably, the boys that Rose kidnaps en route to LA also grow up to be some of the Farmboys, although it's never stated outright which boy is which.
* In the Creator/AndrewLloydWebber musical ''Aspects of Love'', two actresses play Jenny at age 12 and age 15. In the Broadway production they were similar-looking sisters, but the original London production had two non-related girls.
* ''[[Literature/AuntieMame Mame]]'' follows Patrick Dennis, both as a 10 year-old and as a young adult. As such, there are two actors. And they sing a duet at the start of act 2.
* In ''Theatre/OnceOnThisIsland'', Ti Moune ages from a small child to a young adult in the space of about five seconds as part of a song, requiring the use of this trope.
* The ballet ''Theatre/FallRiverLegend'' casts two dancers as the Accused (Lizzie Borden), one playing her as a teenager and one as an adult. They occasionally dance together, but without the younger Accused acknowledging her older self.
* Glen Tetley's ballet adaptation of ''Literature/AliceInWonderland'' has two dancers as Alice, one as an older woman and one as a child.
* In most productions of ''Theatre/TheNutcracker'', Clara is played by one young actress throughout. However, the Mariinsky Ballet's version, in which the character is called 'Masha', will cast a young girl (eleven or twelve) as Masha in the first act, and transition to an older dancer (usually a student in her last few years at the Vaganova Academy) for the second act, known as 'Princess Masha'. This is due to Princess Masha's significantly more complicated dancing in the second act in this particular production. As with other theatre productions, it's not uncommon for the same student to play Masha and then, several years later, play Princess Masha.

* In ''VideoGame/MetalGearSolid3SnakeEater'', a prequel to the entire ''Franchise/MetalGear'' series, young Ocelot is voiced by Creator/JoshKeaton instead of Patric Zimmerman, who voices "present day" Ocelot, and in ''VideoGame/MetalGearSolidVThePhantomPain'', which is set between the two, he's voiced by Creator/TroyBaker. There's also [[spoiler:SIGINT, voiced by James Mathis, who is revealed later in the series to actually be a young Donald Anderson, played by Greg Eagles in ''VideoGame/MetalGearSolid''. But then that Anderson was a fake anyway.]] As well, there's Big Boss, who is voiced by Creator/DavidHayter in ''Metal Gear Solid 3'', Creator/KieferSutherland in ''Metal Gear Solid V'', [[spoiler: and Richard Doyle in ''VideoGame/MetalGearSolid4GunsOfThePatriots.'']]
** Kazuhira/[=McDonnell=] Miller is another example, having gone from Creator/CamClarke in ''[=MGS1=]'' to Creator/RobinAtkinDownes for ''VideoGame/MetalGearSolidPeaceWalker'' and ''MGSV''. [[spoiler:It's also similar to the Sigint/Anderson example, in that the Miller of [=MGS1=] isn't the real Miller, but rather Liquid Snake (also voiced by Clarke) impersonating him.]]
* ''VideoGame/TheLongestJourney'' features April Ryan and Young April Ryan.
* In ''Videogame/FinalFantasyX'', the adult Tidus was played by Creator/JamesArnoldTaylor, while the young Tidus was voiced by Creator/CreeSummer in that game and Shaun Fleming in ''Franchise/KingdomHearts''.
* Speaking of Cree Summer, in ''VideoGame/{{Fallout|1}}'' she voices Tandi as a sixteen year old girl. In ''VideoGame/{{Fallout 2}}'', Tandi is now President of the New California Republic and aged 96, with Creator/TressMacNeille taking over her voice.
* ''VideoGame/BatmanArkhamSeries'':
** ''VideoGame/BatmanArkhamAsylum'' sees Creator/RickDWasserman voice a young Jim Gordon during the flashback to the murder of Thomas and Martha Wayne during the second Scarecrow hallucination, rather than Creator/TomKane, Gordon's voice actor in the present day of the game. The same flashback sees Creator/KimberlyBrooks voice the young Bruce Wayne.
** Unlike ''VideoGame/BatmanArkhamAsylum'' and ''VideoGame/BatmanArkhamCity'', which saw Creator/KevinConroy and Creator/MarkHamill reprise the respective roles of [[WesternAnimation/BatmanTheAnimatedSeries Batman and the Joker]], ''VideoGame/BatmanArkhamOrigins'' sees Creator/RogerCraigSmith as Batman and Creator/TroyBaker as the Joker because ''Origins'' takes place at an earlier place.
* In the English dub for ''VideoGame/KingdomHearts'' Kairi is voiced by Creator/HaydenPanettiere and Creator/AlysonStoner, whereas the younger version is Creator/ArielWinter.

[[folder:Web Original]]
* In ''WebVideo/AtopTheFourthWall'''s ''Franchise/{{Superman}} vs. the Franchise/{{Terminator}}'' #1 episode, Linkara's self from 2039 was played by his real-life father.
* Hilarious played straight in [[http://picnicface.com/videos.php?videoID=18 this Picnicface video.]]

[[folder:Western Animation]]
* In the ''WesternAnimation/{{Ben 10}}'' franchise, Creator/TaraStrong voiced the titular ten-year-old in the original series. When the character was aged up to fifteen for ''[[WesternAnimation/Ben10AlienForce Alien Force]]'', Creator/YuriLowenthal took over and continued on in ''[[WesternAnimation/Ben10UltimateAlien Ultimate Alien]]''. The same applies for the respective actors behind Gwen and Kevin.
** Meanwhile, Fred Tatasciore has voiced an adult Ben and Tara Strong an adult Gwen.
** Unlike Ben, though, anytime we see a younger Gwen after the original series [[FlashbackWithTheOtherDarrin she still has the same voice actor as she does as a teenager.]] This also extends to the adult Gwen.
* Franchise/{{DCAU}}:
** In ''WesternAnimation/SupermanTheAnimatedSeries'', teen and adult Clark are not voiced by the same person. (However, in ''WesternAnimation/LegionOfSuperHeroes'', the same actor voices teen and adult Clark equally convincingly.)
** Another example is the ''WesternAnimation/JusticeLeague Unlimited'' episode, "Kids' Stuff." Superman, Batman, Wonder Woman and Green Lantern are magically made into children and voiced by age appropriate actors.
*** Brought home in episodes of ''WesternAnimation/BatmanBeyond'' set in the future, which feature a robust 60-something Superman now voiced by Christopher [=McDonald=] - the voice of Superman's father Jor-El in all his DCAU appearances.
* ''WesternAnimation/{{Futurama}}'' averts this trope with the main crew, who are played by the same actors when we see them as children and as older adults. The trope is played straighter with many of the secondary characters (such as Fry's brother).
* ''WesternAnimation/HeyArnold'': Arnold is voiced by Rusty Flood in the flashbacks in "Parents Day" and "Helga on the Couch" instead of his normal voice actors (he was [[TheOtherDarrin recast many times]]). Likewise, Helga was voiced by creator Creator/CraigBartlett's daughter Katie instead of Creator/FrancescaMarieSmith during the same flashback in the latter episode.
* In ''Beforel Orel'', the prequel to ''WesternAnimation/MoralOrel'', Clay's father (and Orel's grandfather) Arthur is voiced by Joe Unger, instead of the show's creator, Dino Stamatopoulos.
* This was averted with ''WesternAnimation/APupNamedScoobyDoo'', where Creator/DonMessick and Creator/CaseyKasem reprised their roles of Scooby and Shaggy respectively. Fred, Velma, and Daphne did have real children as their voices though, instead of their respective adult voice actors, with this being the first and only time to date (not counting the live-action films) that Fred was played by someone other than Creator/FrankWelker.
* ''WesternAnimation/{{Recess}}: All Growed Down'' averts this trope during the scene when we see the nine-year-old cast as kindergarteners, however, this led to some awkward moments regarding the voices of Mikey and Vince, as their voices already broke (Mikey's during the break between the end of the series and production on the DTV movies, and Vince mid-way through the first season). Played straight somewhat as T.J.'s voice actor was replaced with a much younger kid with a higher voice (making his portrayal of T.J. loathed among the fandom), which worked ''well'' for his kindergarten scenes.
* Averted in ''WesternAnimation/TheSimpsons'', in which the actors will voice their characters' young selves in flashbacks and the children's voice actors voice the character's adult selves in future episodes.
* In ''WesternAnimation/StarWarsTheCloneWars'' and the holocron recording of him in the [[Recap/StarWarsRebelsSparkOfRebellion first episode]] of ''WesternAnimation/StarWarsRebels'', Obi-Wan Kenobi is voiced by Creator/JamesArnoldTaylor. When he turns up in person in the third season of ''Rebels'', he's voiced by Creator/StephenStanton, who it turns out does a mean Creator/AlecGuinness impression.
* In ''WesternAnimation/SymBionicTitan'', we see a younger Lance in two episodes, both voiced by child actors instead of Kevin Thoms. Although in "Shaman of Fear", he is voiced by Elan Garfias and in [[WholeEpisodeFlashback "Shadows of Youth"]] [[TheOtherDarrin he is voiced by]] John [=DeVito=], despiting his younger self appearing to be roughly the same age both times.
* In ''{{WesternAnimation/Thundercats 2011}}'', the younger Lion-O is played in one episode (as well as in a short where he's a baby) by Creator/TaraStrong. Interestingly, Cheetara's younger self is voiced in flashback by Music/GreyDeLisle, who frequently works with the former.
* ''WesternAnimation/StarVsTheForcesOfEvil'': Queen Moon is voiced by Creator/GreyDeLisle, but a flashback in "Moon the Undaunted" has her teenage self being voiced by Eden Sher, who voices Moon's daughter Star.
