->''"For many years, Creator/SammyDavisJr was a member of the Church of Satan. As you might expect, Davis had to keep this whole matter fairly private or else the truth could ruin him. Alternatively, he could opt to straight up not give a shit and star in the world's first sitcom set in hell. Davis chose the latter path and took the lead role in a pilot called ''Poor Devil'', also starring [[Creator/AdamWest Adam "Batman" West]] and [[Creator/ChristopherLee Christopher motherfuckin' Saruman Lee]] as Lucifer! That the show isn't still on today is undeniable proof that the Nielsen ratings system is rigged."''
-->--'''''Website/{{Cracked}}'''''

This is simply when an actor's role in a film in some way mirrors or parodies their RealLife circumstances and/or career and other roles they're famous for. This forms a small joke or minor piece of merriment. Note that the gag is dependent on the casting and the role only rather than some later effected plot or dialogue. It should be fairly easy to describe the gag as "casting actor X (who is Y) in the role of character Z (who is Y)".

Sometimes it may overlap with ActorAllusion for another character where their respective actors have worked together before. However, the two must not be confused. A CastingGag relies upon casting an actor in a role that reflects on their RealLife history. An ActorAllusion is any character, plot or situation that references ''a previous plot or role'' for the actor.

There is also MetaCasting, which is when such a gag is used specifically to cause a resonance between the character and the audience.

An actor can use this self-consciously for themselves for AdamWesting. Compare with PlayingAgainstType where the casting may feel like a joke for the wrong reasons. Contrast with StuntCasting where the big name actor is not being used for any in-joke but as a piece of marketing to draw in a wider crowd. When the CastingGag is specifically that the person cast is an ActorAllusion for an already estabilished character, it's IWantYouToMeetAnOldFriendOfMine. If the CastingGag is that the actor appeared in an earlier version of the same story, it's a RemakeCameo. Compare also to CastTheExpert.

!!Examples:

[[foldercontrol]]

[[folder:Anime]]
* Manga/SeitokaiYakuindomo has Furuya, who enjoys old-world snacks, uses 80's slang, and does her calculations on an abacus...even her fanservice is old-school. She's played by Creator/HiranoFumi, best known as the voice of Lum in the 80's series Creator/UruseiYatsura.
* In ''Franchise/{{Jewelpet}}'', Creator/MamoruMiyano voiced the DeadpanSnarker secretary agent Keigo Tatewaki. His ComicallySerious demeanor brings back [[Anime/MobileSuitGundam00 Setsuna F. Seiei]]'s portrayal in the CD dramas.
** Creator/MiyukiSawashiro as well. Her portrayal of Opal in Kira Deco oozes ''VideoGame/{{Catherine}}''. Even better, she's the voice of Twilight Sparkle (who'll become an alicorn) in the Japanese dub of ''WesternAnimation/MyLittlePonyFriendshipIsMagic''.
* Creator/JunFukuyama, who is known for playing [[Anime/CodeGeass Lelouch]], has recently been cast as [[Anime/TheLegendOfTheLegendaryHeroes Ryner Lute]], another character who possesses a MagicalEye.
** [[Franchise/{{Jewelpet}} Dian]] has the same power, the same motivation and even a human form that resembles Lelouch, however he's more sinister and vengeful (in the first series).
* [[OlderThanTheyThink A relatively early example]] of this was the casting of Creator/KotonoMitsuishi as Misato in ''Anime/NeonGenesisEvangelion''. Creator/HideakiAnno stated that Misato was basically [[Anime/SailorMoon Usagi Tsukino]] (Mitsuishi's most famous role) if she'd grown up to be a very unhappy adult.
** Another came when they cast Kyoko Zeppelin (Asuka's mother). Asuka is often seen as a SpiritualSuccessor to Jung Freud from Gunbuster, so they got Creator/MariaKawamura to play Asuka's mother.
* In ''Manga/LuckyStar'', Konata works in a CosplayCafe and dresses as LightNovel/HaruhiSuzumiya, both characters having been voiced by Aya Hirano, as well as Creator/WendeeLee in the English dubs (Though ''Manga/LuckyStar'' as a whole is full of [[ShoutOut shout outs]] and other things like these).
* In the English version of ''Anime/CodeGeass'', Creator/JohnnyYongBosch stars as an intelligent and occasionally NecessarilyEvil pragmatist whose ideals clash with YuriLowenthal, his passionate and idealistic childhood friend. In ''Anime/TengenToppaGurrenLagann'', YuriLowenthal stars as a passionate idealist whose ideals clash with Creator/JohnnyYongBosch, his intelligent and pragmatic childhood friend. Amusingly, while their roles are the same, the "right" and "wrong" sides are reversed.
* In the English dub of ''Anime/CowboyBebop'', DaranNorris voices both as Andy, a comical character who is Spike's rival during one episode, as well as the antagonist Vincent in the film, who is an EvilCounterpart to Spike.
* In ''Manga/OnePiece'', the Japanese voice actors for the Straw Hat pirates ''also'' provide the voices for a group of impostors trying to gain infamy by posing as the Straw Hats. They also mix up who is who, such as Sanji's voice actor playing the fake Luffy or Chopper's as the fake Nami.
** Maybe this, maybe just a [[ContrivedCoincidence coincidence]]: Igaram's voice actor from the 4kids Dub plays Igaram's wife Terracotta in the Funimation Dub.
* In ''Manga/{{Naruto}}'', the seiyuus of the six dead Jinchuurikis also play their six Bijuus. But they mix up the roles, so none of those Jinchuurikis share his/her voice with his/her own Bijuu. For example, Yondaime Mizukage Yagura's seiyuu Creator/MiyuIrino plays him and the Rokubi [[spoiler:Saiken]], Utakata's Bijuu.
* In ''Anime/DogDays'', both Creator/MinakoKotobuki and Creator/KanaHanazawa, well known for their roles as [[Manga/KOn Mugi]] and [[LightNovel/OreNoImoutoGaKonnaNiKawaiiWakeGaNai Kuroneko]] respectively, voice ActionGirl variants of those characters.
* In ''LightNovel/BokuWaTomodachiGaSukunai'' Creator/YukaIguchi voices Maria who is basically [[ToAruMajutsuNoIndex Index]] with lavender hair and a dark blue habit.
* ''Manga/FullmetalAlchemist'': Creator/AaronDismuke did the voice of Alphonse in the English dub of the [[Anime/FullmetalAlchemist 2003 anime]], but puberty made it impossible for him to reprise the role for ''Brotherhood''--so he did the voice for Al's father, Hohenheim, as a young man.
** There also exists another gag: Creator/LuciChristian, who played the 2003 anime's incarnation of Wrath, provides the voice of the Truth in ''Brotherhood''. Both characters are strikingly similar in that [[spoiler:both meet Edward at the GateOfTruth and end up taking his arm and leg for themselves, keeping them until the end of the storylines they appear in (except Wrath loses both limbs while the Truth keeps Ed's leg)]]. Considering the Truth simply shares the same voice actor as the one it appears before in the original Japanese language, the fact that they had a single person to portray a character that had something in common with one of her earlier roles in the franchise couldn't be called anything less than a tribute.
* ''GaReiZero'': Funimation cast many of their ''most popular'' voice actors to play the five Agency squad members in Episode 01 only. [[spoiler:Why Episode 01 only? [[DecoyProtagonist ....because they all get killed off!]] Could be a bit of dark humor on Funimation's part.]]
* With FUNimation finally dubbing the second season onwards of ''ShakuganNoShana'', Shana is voiced by Creator/CheramiLeigh, who has some [[FieryRedhead experience]] [[{{Tsundere}} with]] [[KazeNoStigma the role]].
* The anime adaptation of ''[[Manga/NoMatterHowILookAtItItsYouGuysFaultImNotPopular No Matter How I Look at It, It's You Guys' Fault I'm Not Popular!]]'' has Izumi Kitta playing Tomoko. The seiyuu in question also plays Rainbow Dash in the Japanese dub of ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', who is... pretty much Tomoko's opposite in every way.
* In some sort of weird twist on TheDanza, both ending themes for ''Anime/NagiNoAsukara'' are performed by [[http://en.wikipedia.org/wiki/Nagi_Yanagi Nagi Yanagi.]]
* ''Anime/GundamBuildFighters'' engages in a lot of this by having several characters played by ''{{Franchise/Gundam}}'' veterans. However, the biggest example has to be Mr. Ral, who not only looks identical to and acts a lot like AntiVillain Ramba Ral from [[Anime/MobileSuitGundam the original series]], but is played by the same actor, MasashiHirose. Since the ''Gundam'' anime exists in the ''Build Fighters'', this also creates an odd example of CelebrityParadox.
* Atsuko Ishizuka, the director of the anime adaptation of ''LightNovel/NoGameNoLife'', has previous experience on ''LightNovel/SakurasouNoPetNaKanojo''. Perhaps it's no coincidence that Creator/YoshitsuguMatsuoka and Creator/AiKayano, who voiced the lead pair of lovers in ''Sakurasou'', would be once again cast to play, in ''No Game No Life'', a pair of gamer-siblings. The gag went further due to the names of the characters involved: Sorata and Mashiro[[note]]"Sky-the-eldest" and "Pure-white"[[/note]] in ''Sakurasou'', and Sora and Shiro[[note]]"Sky" and "White"[[/note]] in ''No Game No Life''.
[[/folder]]

[[folder:Film]]
* Possibly the most illustrious example of this is ''Film/SunsetBoulevard'', in which Gloria Swanson, who was an over the hill, forgotten silent movie actress, plays an over the hill silent movie actress.
** At the same time, she employs a butler who was once a famous, now forgotten, silent film director. This part is played by the once famous, then forgotten silent film director Erich von Stroheim.
** When Swanson's character is seen watching one of her old movies, it is ACTUALLY an old Gloria Swanson movie - directed by Erich von Stroheim.
** And then there's her card-playing buddies from the Old Days ("the Waxworks"), including Creator/BusterKeaton.
** To complete the circle, Swanson at one point goes to Cecil B. De Mille to beg a part in his new movie. The director played himself, and the scene was shot on the set of his ACTUAL current movie.
* Carrie Fisher has a cameo in ''Film/{{Scream 3}}'' as "Bianca" who is bitter over losing out for the role of Princess Leia to another actress. She goes as far to state that the actress 'must have slept with George Lucas'.
** Also Carrie Fisher, Billy Dee Williams and Ray Park have all appeared in ''Fanboys'' because of their roles in StarWars. The fact that they played different characters added to the level of hilarious.
* Sigourney Weaver plays a ([[DyeingForYourArt blonde!]]) BridgeBunny in ''Film/GalaxyQuest'', a character significantly at odds to her best known role, Ellen Ripley of ''Franchise/{{Alien}}''. In the same film, Tim Allen is very convincing as a washed up TV star, and Creator/AlanRickman is excellent as a respected [[Creator/WilliamShakespeare Shakespearean]] actor playing [[ClassicallyTrainedExtra a role far below his ability.]]
* In ''Film/{{Avatar}}'' Sigourney Weaver fights to ''protect'' the aliens. And the film is by [[Creator/JamesCameron the same director]] of ''Aliens''.
* In ''Film/{{Paul}}'', Sigourney Weaver plays the BigBad that hunts [[spoiler: the titular Franchise/{{Alien}}.]]
* In ''ShakespeareInLove'', Ben Affleck (who was a big name at the time, possibly less so now) has a small role as a big name actor who is tricked into accepting a small role in ''RomeoAndJuliet''.
* David Duchovny in ''{{Zoolander}}'' as a conspiracy nut.
* In the 1970's movie Cannonball Run, one of the racers has the delusion that he is a famous movie star named Roger Moore, and has lots of zany gadgets including an ejection seat in the car. Of course, the character is played by Roger Moore, who was one of the James Bond actors.
* ''Film/FreakyFriday2003'' wanted to do this with Creator/JodieFoster who played the daughter in the original ''Film/FreakyFriday'' now playing the mother, however she declined.
* In ''Film/{{Clue}}'' we get this StealthPun Casting Gag:
** "Mr. Boddy won't be staying with us for very long. In fact, he's just Lee Ving."
* ''SkyHigh'': Lynda Carter, former Series/WonderWoman, as the Sky High Principal.
** Who, at one point, quips [[ActorAllusion "I'm not a wonder woman, you know."]]
* [[SilenceOfTheLambs Anthony Hopkins]] was cast as [[ImAHumanitarian Titus]] in the film adaptation of ''Theatre/TitusAndronicus''.
* Christopher Walken appears in ''Film/PulpFiction'' as a former Vietnam POW. Knowing Creator/QuentinTarantino, this is most likely a reference to Walken's role in ''Film/TheDeerHunter''.
* In ''Film/IronMan1'', the [[TheStinger after-credits]]-appearing character NickFury is played by Creator/SamuelLJackson who serves (with his permission) as the model for the appearance and personality of the UltimateMarvel version of Fury. Within the comic ''TheUltimates'' itself, when the team was amusing themselves speculating on who would play them in the movie about their adventures, Fury said that he would of course be played by Samuel L. Jackson.
** A popular theory is that Jackson agreed to provide his likeness for the Ultimate Universe Nick Fury, with the understanding that if ever there was a movie with Nick Fury, he would get to play the role.
** Ghostface Killah -- who uses "Tony Starks" as an alias, titled his 1996 solo debut album ''Ironman'' and opened his 2000 album ''Supreme Clientele'' with a clip of the theme to the old ''WesternAnimation/IronMan'' cartoon -- was actually cast in a supporting role in the film as an industrial tycoon (his scene didn't make it to the final cut).
** Additionally, guitarist Tom Morello appears as one of the terrorists who try to kill the first Iron Man suit. To get the gag you have to remember that he is most famous for playing with "RageAgainstTheMachine." (Morello later co-scored the sequel)
** And then there were the endless jokes about casting Robert Downey Jr. as [[TheAlcoholic Tony Stark.]] And now he will be playing Film/SherlockHolmes, who had a bit of a thing for cocaine.
** On top of that, [[Creator/BenKingsley Gandhi]] plays a terrorist in ''Film/IronMan3''.
*** Who turns out to be [[spoiler: a British actor posing as a DecoyLeader]]. MetaCasting indeed.
* From ''Film/{{Maverick}}'':
** A CastingGag played as ActorAllusion, the title character (played by Creator/MelGibson) is in a bank as it is held up by an unnamed bank robber played by Danny Glover who starred alongside Gibson in the ''LethalWeapon'' series of movies. Maverick acts as though he recognises the voice of the bank robber and pulls down his mask, leading the two of them to share a moment before shaking their heads and walking away.
** And the unnamed bank robber also mentions that he's "getting too old for this" as he makes his getaway.
** Further, The film features the often-referenced-in-the-series-but-never-seen father of Bret Maverick -- who, just coincidentally, happens to be played by none other than JamesGarner, who originated the role of Maverick on TV.
* Very possibly the casting of Creator/RobinWilliams, TV's ''[[MorkandMindy Mork From Ork]]'' in TheSeventies, as ''Film/{{Popeye}}'', searching for his long lost father, Poopdeck Pappy, played by Ray Walston, TV's loveable alien from TheSixties on ''MyFavoriteMartian''.
* [[Series/{{Dallas}} Larry Hagman]] in Oliver Stone's ''Nixon'', playing a Texas billionaire.
* Since the new resurgence of superhero films began, comic book legend StanLee [[CreatorCameo has had a cameo in most of the film series of Marvel characters he helped to create]], from ''Film/SpiderMan'' to the ''Film/{{X-Men}}''.
** Usually he's just being heroic, but he got to play a character he created, Willie Lumpkin, in the Fox ''Film/FantasticFour'' movie.
*** He was a miss pagent judge in ''Film/IronMan3''. Truly a hero to the good old US of A. :)
* ''Film/TheRockyHorrorPictureShow'' creator Richard O'Brien was probably best-known in the UK during the 90s for hosting ''TheCrystalMaze'', a game show in which contestants had to win crystals (and ultimately prizes) by solving puzzles on a large, labyrinthine set. He was later cast in the ''Film/DungeonsAndDragons'' film as the master of a large maze from which the heroes have to retrieve a gem.
* In Kenneth Branagh's film ''HenryV'', the actor Michael Williams, Judi Dench's husband, was cast as the character Michael Williams after she signed on to the film.
* At the beginning of ''LoveActually'', Liam Neeson's character is giving a eulogy for his wife, and he jokingly mentions that they had a lot of time to discuss things when she was ill, and one of her suggestions was that he bring Claudia Schiffer as his date to the funeral. This gets a callback later when he tells his stepson that he plans on never finding love again -- unless he should run into Claudia Schiffer. At the end, he's at the stepson's school, trying to help him resolve his own unrequited love for a classmate... and he bumps into another parent he's never met before, who introduces herself as [[strike: Carol]] Karen (he stammers a bit and calls her Carol, though). She's is played by Claudia Schiffer.
* Thoroughly unintentional example (they initially refused to even let her audition): Paris Hilton in ''RepoTheGeneticOpera'' playing... a rich, slutty, fashion-obsessed heiress cultivating a singing career using her name and infamy rather than talent. Better than it sounds, not least because [[spoiler:her face falls off]].
* In ''Literature/BridgetJones' Diary'', Colin Firth was cast to play Mark Darcy, a character inspired by Fitzwilliam Darcy (from PrideAndPrejudice) which he played in a series of made for TV films. On top of that, in the original novel, Bridget and her friends are stated to lust after the actor and his famous [[ShirtlessScene wet shirt scene]].
* The titular ''[[TheMenWhoStareAtGoats Men Who Stare At Goats]]'' call themselves "Jedi Knights." So who should be cast as the reporter writing a story on this covert group of psychic warriors, making such statements as, "I don't understand what a Jedi Knight is"? EwanMcGregor.
** According to [=McGregor=], the director didn't even realize this, although [=McGregor=] himself played it up.
* Is it just a coincidence that Nestor Carbonell, who played Mayor Anthony Garcia in ''Film/TheDarkKnight'' and ''Film/TheDarkKnightRises'', also played Batmanuel in the TV Show of TheTick?
** Also, in ''Film/TheDarkKnightRises'', Matthew Modine plays Deputy Commissioner Peter Foley. Modine also played a character nicknamed "Joker" in the 1987 film ''Film/FullMetalJacket''.
* Creator/DerekJacobi, famous for ''Series/IClaudius'', as a Roman senator in ''Film/{{Gladiator}}'' and as King ''Claudius'' in Branagh's ''{{Hamlet}}''.
** Jacobi's character in ''DeadAgain'' [[spoiler: stutters]], just like Claudius.
** Jacobi plays the Archbishop of Canterbury in ''The King's Speech'', which is all about another monarch getting over a SpeechImpediment, and arguably, the clergyman role could be a ''Series/{{Cadfael}}''-based CastingGag.
* In David Mamet's adaptation of the play ''Film/TheWinslowBoy'', Neil North plays the First Lord of the Admiralty. In the 1948 film of the same play, North had played the title character (a supporting role).
* The same year Mark Williams was cast as the technology-loving wizard Arthur Weasley in the ''Film/HarryPotter'' movie series, he was also an enthusiastic presenter in ''Industrial Revelations'', a documentary series about the history of technology.
** In ''[[Literature/HarryPotterAndTheHalfBloodPrince Half-Blood Prince]]'', after Bill was attacked, he was said to bear a distinct resemblance to Mad-Eye Moody. In ''[[Film/HarryPotterAndTheDeathlyHallows Deathly Hallows]]'', Bill was played by Domhnall Gleeson whose father, Brendan Gleeson, played Moody.
** Also in ''Half-Blood Prince'', Lord Voldemort's child self is played by Hero Fiennes-Tiffin, nephew to Creator/RalphFiennes who portrays the character's adult incarnation.
** In the epilogue, Draco Malfoy's wife was played by Creator/TomFelton's real life girlfriend.
* Miranda Richardson has been in so many roles that involve [[OffWithHisHead beheading]] -- Queen Elizabeth in ''{{Blackadder}} II'', the Queen of Hearts in 1999's ''Literature/AliceInWonderland'' TV miniseries, Lady Van Tassel in ''Film/SleepyHollow'' -- that it's hard to imagine her role as the chicken-killing Mrs. Tweedy in ''WesternAnimation/ChickenRun'' being anything other than an allusion to her past head-removing roles.
* Creator/SeanConnery was cast as Franchise/IndianaJones' father in ''Film/IndianaJonesAndTheLastCrusade'' because Creator/StevenSpielberg and Creator/GeorgeLucas thought that the only man who could play Indy's father was Film/JamesBond, and because in a meta sense, James Bond ''was'' the father of Indiana Jones. ''Film/RaidersOfTheLostArk'' came about when Creator/StevenSpielberg told George Lucas that he wanted to make a Bond movie; Lucas pitched his "Indiana Smith" character as a rights-free alternative, and the rest is history.
** And to really push the joke home, four other actors had been in Bond films (Julian Glover was Bond villain Kristatos in ''Film/ForYourEyesOnly'', Alison Doody was Bond girl Jenny Flex in ''Film/AViewToAKill'', John Rhys-Davies was Bond ally Pushkin in ''Film/TheLivingDaylights'' (albeit that was after ''Raiders''), and Vernon Dobtcheff (the Brunwald castle butler) was nightclub owner Max Kalba in ''Film/TheSpyWhoLovedMe''. Michael Byrne later played a British naval officer in ''Film/TomorrowNeverDies''.
** He similarly played the [[Literature/KingSolomonsMines proto-Indiana]] in ''Film/TheLeagueOfExtraordinaryGentlemen''. And, although the filmmakers weren't able to get this into the movie version, the team that he leads was formed by James Bond's grandfather in [[TheLeagueOfExtraordinaryGentlemen the original graphic novel]].
** Though it was ultimately averted, the production team behind ''Film/{{Skyfall}}'' confirmed they considered asking Connery to play Bond's eldery gameskeeper Kincaid, but deemed it too distracting. Would also have been an example of RemakeCameo.
* John Hurt, who played the lead role of Winston Smith in British movie ''[[Literature/NineteenEightyFour 1984]]''; was in 2006 cast as the dictator for the film ''Film/VForVendetta'', which bore a similar setting. The dictator's face is seen displayed over several screens throughout the city, all in a very Big Brother-esque way.
* Matt Damon as the hero and Greg Kinnear as the BigBad in ''GreenZone''. Both had previously starred as conjoined twins in the Farelly Brothers comedy ''Stuck On You''.
* In ''EnemyOfTheState'', Gene Hackman plays a character who seems like a good-guy version of his "professional eavesdropper" character in ''Film/TheConversation''. This is referenced when a photograph of Hackman's character from that earlier film is used as a file photo in ''EnemyOfTheState''.
* In ''Piranha3D'', Richard Dreyfuss has a cameo at the beginning as a character who is practically Matt Hooper from ''Film/{{Jaws}}''.
* ''BladesOfGlory'' manages to make ''[[BrotherSisterIncest incest]]'' both funny and pretty much a foregone conclusion by casting (then) [[CastIncest real-life husband and wife]] Will Arnett and Amy Poehler as [[{{Twincest}} fraternal twins]] Stranz and Fairchild Van Waldenberg.
* ''Film/HotFuzz'' casts Edward Woodward as [[spoiler: the equivalent of his antagonists from ''Film/TheWickerMan'']]
* In ''Film/{{Airplane}}'', Kareem Abdul-Jabbar, who's cast as pilot Roger Murdock, is pointed out by a boy on the plane as being Kareem Abdul-Jabbar. The boy continues to ask Murdock why he doesn't put more effort into his basketball, to which Murdock heavily implies he's Kareem Abdul-Jabbar hiding as a pilot. [[RunningGag Finally]], when Murdock has to be taken off the co-pilot seat after suffering food poisoning, he is revealed to be wearing his basketball shorts and shoes.
** Also, there's one scene in a mental hospital for soldiers with PTSD. One of the soldiers thinks he's Ethel Merman, and he's played by none other than Ethel Merman herself.
*** Additionally, casting Peter Graves, Robert Stack, and Leslie Nielsen was in-and-of-itself a Casting Gag because [[LeslieNielsenSyndrome they had never acted in comedic roles before]] ''Airplane!''
* In ''Film/TheFlintstones'' movie, Fred has a secretary named Sharon Stone (a reference to both the actress and the non-stop "rock" puns common in the TV series). The producers wanted Sharon Stone to be played by... Creator/SharonStone, who had to turn down the role as she was working on another movie (the part was taken by Creator/HalleBerry). Stone has since expressed her regret for not appearing in the Flintstones.
* David Rasche plays a senator in Clint Eastwood's ''FlagsOfOurFathers''. Rasche is most famous for spoofing Eastwood's DirtyHarry character as the trigger-happy, fascist CowboyCop ''Series/SledgeHammer''.
* In ''Film/AFishCalledWanda'', George Thomason is played by Tom Georgeson.
* In ''Film/{{Unknown}}'', Aidan Quinn plays the sinister impostor "Martin B", who steals the identity of Martin Harris (Creator/LiamNeeson). They had both played best friends in ''MichaelCollins'', and Neeson suggested that he be cast opposite him as the villain.
* Maybe: In ''Film/AtlasShrugged'' Part 1, one of Dagny's enemies is played the actor who was both [[Series/StarTrekDeepSpaceNine Quark]], an alien who's [[PlanetOfHats "Hat"]] is greed and business prowess and [[VideoGame/BioShock1 Andrew Ryan]], extreme business-liberal and parody of ''Atlas'' author Creator/AynRand.
* In the original version of ''Film/TheParentTrap'', the father's evil girlfriend is named Vicky. In the remake, the evil girlfriend Meredith's mother says, "You may call me Aunt Vicky." She was played by the same actress who played Vicky in the original.
* In ''Film/BattleBeyondTheStars'' Robert Vaughn plays the RecycledInSpace version of his character from ''TheMagnificentSeven''.
* In ''Film/LordOfTheRings'', Gimli nudges Legolas's bow so that the intended warning shot would nail one of Sauron's pirate reinforcements right in the chest. the pirates were all played by the production staff and the pirate that gets killed? Peter Jackson, the director.
** Ian Holm plays Bilbo, but was Frodo, Bilbo's nephew in the 1981 radio drama.
* Creator/TimBurton has a brief [[TheCameo cameo]] in ''Film/{{Singles}}'', playing a disheveled, artistic amateur film director.
** Also in Burton's ''Film/DarkShadows'', Chloe Moretz, who previous played a vampire in ''LetMeIn'', plays...a werewolf.
* In ''Film/{{North}}'', Kelly [=McGillis=] has a cameo as an Amish woman and Alexander Gudunov as her husband- they famously played Amish people in ''Film/{{Witness}}''.
* Porn stars cast as porn stars (movie edition):
** In ''Film/BoogieNights'', several porn stars (most notably Nina Hartley) had bit parts in the movie.
** In ''Film/TheBigLebowski'', Asia Carrera had a cameo as one of the actresses in the fictional porn film ''Logjammin'''.
** In ''Film/{{Striptease}}'', Pandora Peaks played Demi Moore's stripper friend Urbanna Sprawl.
** In ''Film/ZackAndMiriMakeAPorno'', porn stars Katie Morgan and Traci Lords play porn stars.
** In ''{{Orgazmo}}'', Ron Jeremy plays a porn star who may or may not have been intended to be himself.
* In ''Photographing Fairies,'' Edward Hardwicke plays Creator/ArthurConanDoyle. At the time, Hardwicke was best known as the [[TheOtherDarrin second Dr. Watson]] in Granada's ''Series/SherlockHolmes''.
* In ''[[Film/LooneyTunesBackInAction Looney Tunes: Back In Action]]'', Brendan Fraser plays the part of Brendan Fraser's stunt double. Later on, he punches "Brendan Fraser" in the face.
--> '''DJ:''' Did you see those [[Film/TheMummyTrilogy Mummy]] movies? Yeah, I'm in them more than Bren Fraser is.
* ''Film/LesMiserables2012'', the most recent film version of the musical, features several of the original stage actors in cameos, most notably Colm Wilkinson (the original Jean Valjean) as the Bishop of Digne, who gives Valjean the candlesticks, Frances Ruffelle (the original Eponine) as "The Most Fabulous Whore" in "Lovely Ladies", Samantha Barks as Eponine (a role she played in the West End production). Also, the casting of Creator/AnneHathaway as Fantine counts because Hathaway's mother was Fantine in the first U.S. national tour of the original stage production.
* ''Film/{{Superman}}'' has, in some cuts, a minor scene showing a young Lois Lane riding on a train with her parents. Said parents: Kirk Allen and Noel Neil, who played Superman and Lois Lane in the 1940's serials.
* In the 1951 film ''[[Film/SonsOfTheMusketeers Sons of the Musketeers]]'', Porthos Jr is played by Alan Hale Jr. Alan Hale Sr played Porthos in the 1939 film of ''The Man in the Iron Mask''. (Hale Jr would also go on to play Porthos in another film based on the "Man in the Iron Mask" section of ''The Vicomte de Bragelonne'', 1979's ''The Fifth Musketeer''.)
* The Japanese dub of ''Film/PacificRim'' has MegumiHayashibara as the dub voice of Mako Mori, a Japanese [[HumongousMecha mecha]] pilot with short, blue-tinted hair. [[Anime/NeonGenesisEvangelion Three good guesses as to why she was cast in that role...]]
* Creator/PeterCapaldi as a World Health Organization (W.H.O) Doctor in ''Film/WorldWarZ''. Prior to the worldwide announcement on 4 August 2013, it was mostly unknown that he would play the role of the [[Series/DoctorWho Twelfth Doctor]] (only known to a select few, including some of the show's production staff).
* From ''Film/TheHungerGames'': Josh Hutcherson (Peeta) and Alexander Ludwig (Cato) fight it out after both appearing in movies where they had close relationships with Creator/AnnaSophiaRobb. Hutcherson as her best friend in ''Literature/BridgeToTerabithia'' and Ludwig as her brother in ''RaceToWitchMountain''.
* Sharlto Copley as an AxCrazy mercenary hunting the hero in ''Film/{{Elysium}}'', a reversal from his role in ''Film/{{District 9}}''. Invoked, as Copley wasn't interested in playing essentially the same character again.
* ''Film/SavingMrBanks'': It can't be a coincidence that Creator/EmmaThompson plays P.L. Travers, the author of ''Literature/MaryPoppins'', after having previously played a Poppins-eque MagicalNanny in ''Film/NannyMcPhee''.
* ''Film/WeddingCrashers'': Senator Cleary and his wife Katherine are played by Creator/ChristopherWalken and JaneSeymour, who had respectively played the Bond villain and Bond girl of Creator/RogerMoore's [[Film/AViewToAKill last]] and [[Film/LiveAndLetDie first]] Film/JamesBond films.
* [[Creator/KennethBranagh Sir Kenneth Branagh]] has spent his entire career being compared to and shadowing [[Creator/LaurenceOlivier sir Laurence Olivier]]. So there came as no suprise when he was cast as Creator/LaurenceOlivier himself in ''Film/MyWeekWithMarilyn''.
* In the Creator/JohnnyCash biopic ''Film/WalkTheLine'', Waylon Jennings is played by Jennings' real-life son, Shooter Jennings.
* The film version of ''Film/AStreetcarNamedDesire'' somewhat famously cast Vivien Leigh--who was still best known for playing [[Film/GoneWithTheWind Scarlett O'Hara]] at the time--as the mentally damaged Southern belle Blanche Dubois, [[spoiler: whose tragic inability to cope with the loss of her family's ancestral plantation ultimately costs her her sanity]]. The casting choice helps make Creator/TennesseeWilliams' {{deconstruction}} of American class and gender roles all the more obvious, and it draws attention to Blanche's attachment to her rosy, idealized image of the antebellum South.
* In ''Film/SkyCaptainAndTheWorldOfTomorrow'', the BigBad [[MadScientist Dr. Totenkopf]] never actually appears in the flesh until the final act of the movie, but he's "played" by the late Sir Creator/LaurenceOlivier in pictures and video clips, with several old film clips of Olivier edited together to fit the film's plot. [[spoiler: Somewhat unsurprisingly, Totenkopf turns out to have been DeadAllAlong (just like his actor) when the heroes finally breach his lair.]]
* ''AShotAtGlory'' features former Rangers footballer Ally [=McCoist=] as former Celtic footballer [=Jackie McQuillan=] - the clubs in question are two of the fiercest rivals in world football.
* In a WhatCouldHaveBeen example, Marvel Studios originally wanted Creator/MadsMikkelsen for the role of Malekith the Accursed in ''Film/ThorTheDarkWorld'', which also starred Creator/AnthonyHopkins as Odin. If Mikkelsen had actually been cast in the role, the movie would have featured both Series/{{Hannibal}} [[Film/TheSilenceOfTheLambs Lecters]] squaring off against each other in a war over Asgard.
* In ''[[Film/BackToTheFuture Back to the Future: Part III]]'', Mary Steenburgen stars as Clara Clayton, a 19th century woman who falls in love with a time-traveller from the 20th century, the opposite of her role in ''Film/TimeAfterTime'', where she played a 20th century woman who falls in love with a time-traveller from the 19th century. What's better is her film debut had been in ''Goin' South'', a western-comedy where she was also wooed by Creator/ChristopherLloyd.
* ''Film/XMenTheLastStand'' has former soccer player Vinnie Jones as Juggernaut, whose ''American football'' design is deliberately played up with his "unstoppable" mutant power.
* In ''Film/ManOfSteel'', Clark Kent's two father figures--his biological father Jor-El and his adoptive father Jonathan Kent--are both played by actors who are well-known for having [[Film/RobinHood2010 previously]] [[Film/RobinHoodPrinceOfThieves played]] RobinHood (Creator/RussellCrowe and Creator/KevinCostner, respectively).
* Lucasfilm may have had this trope in mind when they were casting ''Franchise/StarWars Episode II: Film/AttackOfTheClones'' back in 2002, and decided to cast former Creator/HammerHorror leading man Creator/ChristopherLee as the secondary villain Count Dooku--recalling [[Film/ANewHope the 1977 original]], where the secondary villain Grand Moff Tarkin was played by Hammer's ''other'' leading man, Creator/PeterCushing.
* For the 2014 film adaptation of ''Alexander and the Terrible, Horrible, No Good, Very Bad Day'', Alexander will be [[FakeAmerican played by Australia-based child actor Ed Oxenbould]]. In the original book, Alexander, fed up with how terible his day has been so far, insists on moving to Australia.

[[folder: Live Action TV]]
* ''Series/TheBigBangTheory'' had Sara Gilbert play Leonard's love interest; his actor and Gilbert played a couple on {{Roseanne}}
** Laurie Metcalf, most famous as Jackie on the previously stated show, plays Sheldon's mother.
* ''Series/DoctorWho'':
** A blend of this trope and RealLifeRelative turns up in the episode "The Doctor's Daughter", where the titular character is played by Creator/GeorgiaMoffett, real-life daughter of the Fifth Doctor, Creator/PeterDavison.
** Creator/DerekJacobi appeared on the show as Professor Yana, who, [[spoiler:unknown to everyone (including himself), was actually The Doctor's old nemesis The Master. Jacobi had previously played The Master in an animated Doctor Who story]].
*** The Doctor in that animated story, the Ninth, had been played by Richard E Grant, famous for playing [[Film/WithnailAndI Withnail]], the [[HeterosexualLifePartners best friend]] of "[[NoNameGiven I]]", played by Paul [=McGann=] - who was also the Eighth Doctor.
** In the ''Film/AnAdventureInSpaceAndTime'' docudrama, the original voice actor for the Daleks and Cybermen (Peter Hawkins) is played by Creator/NicholasBriggs, the current voice of the Daleks and Cybermen.
** The Doctor and Franchise/JamesBond are often cited as the two quintessential heroes of modern British popular culture, and they're both well-known for having been [[TheOtherDarrin played by a succession of very different actors]] over the course of their long histories. Therefore, the producers probably had this trope in mind when they cast Creator/TimothyDalton as the elder Time Lord Rassilon, the BigBad of "The End of Time".
* ''Series/{{Smallville}}'': The presence of any actor from a previous ''Franchise/{{Superman}}'' series, Creator/ChristopherReeve, Dean Cain, etc. There was also [[TheDukesOfHazzard Tom Wopat]] turbing up as an ActorAllusion to John Schneider but the one that takes the biscuit is the (possible unintentional) casting of Annette O'Toole, Lana Lang in ''´Film/SupermanIII'', as Martha Kent (though the crew didn't actually know about her former role when she was cast).
* In the ''Series/{{Friends}}'' eighth season episode, "The One With The Rumour", Brad Pitt appeared as one of Ross's old high school friends, who hated Rachel to the point that he was president of an Anti-Rachel club in high school. At the time, it was a comic variant of this trope since Brad Pitt was married to Jennifer Aniston in real life. The joke became a lot less funny after Aniston and Pitt's very, very public divorce.
* Cameo Version: In an episode of ''Series/{{Roseanne}}'', Roseanne and Jackie are getting makeovers at a health spa. The makeup artist talks about "less is more" and letting their faces tell their own story. When she turns around, we see for the first time it was Tammy Faye Bakker. [[note]][[DontExplainTheJoke For those to young to get the reference]], Tammy Faye is the wife of notorious televangelist Jim Bakker. She was known for wearing copious amounts of makeup, on par with Mimi from ''TheDrewCareyShow[[/note]]
* Former ''Franchise/PowerRangers'' cast members have come back just to voice a MonsterOfTheWeek. The most extreme example is in ''Series/PowerRangersSamurai'', where the Red Ranger's WorthyOpponent is played by Rick Medina, who was himself a Red Ranger in ''Series/PowerRangersWildForce''.
** Not to mention the irony: The ''Wild Force'' Rangers had Zen-Aku, a monster who was sometimes a human due to a curse that made him want to fight the Rangers, but he'd really rather not have. So Medina goes on to play Deker, who's got the same thing going: he's now ''Samurai's Zen-Aku.'' (Not that Deker's a ''total'' ZA {{Expy}}. ZA's a guy bonded with a Duke Org and his memory's not all there; Deker's an immortal BloodKnight who must defeat his WorthyOpponent (or die at his hands) to be freed from it. However, as Deker is a sometimes-human-faced villain who's not all bad, there's more poetry there than if he'd played, say, the voice of [[BigBad Xandred]].)
** ''Wild Force'' MilestoneCelebration episode "Forever Red" is a big example of this as three of the Machine Empire Generals were voiced by Walter Jones (Zack), Catherine Sutherland (Katherine) and Archie Kao (Kai).
** Though Nic Sampson, ''Series/PowerRangersMysticForce'''s Chip, gets MOTW duty once, he also voices ''Series/PowerRangersOperationOverdrive'''s Sentinel Knight. Chip had once said he hoped to be a knight (which in MF parlance is sort of the rank above Ranger) someday, so he sorta gets to be.
** ''Series/NinpuuSentaiHurricaneger'' had the MasterOfDisguise Shurikenger, who never demorphed (he sacrificed his human form to get his powers and is only seen unsuited as a silhouette in a flashback to that day) but is always at first in disguise as some random civilian. ''Every single one'' is another sentai actor. When changing to Shurikenger, most used the pre-changing poses from their show -- and even when that was impossible in one case, due to a lack of a pose, Creator/KenjiOhba (he's ''both'' Shiro/Battle Kenya and Daigoro/Denji Blue, but the poses you expect these days didn't exist that early on) did the ''Series/SpaceSheriffGavan'' pose instead.
** In ''Series/KaizokuSentaiGokaiger'', Engine Machalcon joins the crew to assist in using the Series/EngineSentaiGoOnger ultimate power. As a Japanese Pirate crew, the Gokaigers are often compared to the [[Manga/OnePiece Straw Hats]], so who else should voice Machalcon but HiroakiHirata aka Sanji!
*** He does it again in the Japanese dub of the PiratesOfTheCaribbean as ''Jack Sparrow!''
** Tetsu Inada is one of the series' go-to voice actors, and he played Doggie Kruger, the chief of SPD's Earth branch, in ''Series/TokusouSentaiDekaranger.'' Taking out a MonsterOfTheWeek was referred to as "deleting" them that year. So when he played an MOTW in ''Series/JukenSentaiGekiranger,'' he says to the other monster, "Let's ''delete'' them!" while doing the SPD salute.
* Casting Dean Stockwell to play against [[Series/QuantumLeap Scott Bakula]] in ''Series/StarTrekEnterprise''.
* There is an episode of ''Franchise/{{Dragnet}}'' where they meet a priest who explains that they are looking for a plaster doll of the baby Jesus that was taken from the church. So they question the altar boy, and an old man who runs a pawn shop. Maybe ten years later, they do a remake of the show. They get the actor who played the altar boy, to play the priest, and they get the same man to play the part of the pawnbroker.
* In ''MissionImpossible'', Barney Collier's son Grant is played by Greg Morris's son Phil.
* In the new ''[[Series/BattlestarGalacticaReimagined Battlestar Galactica]]'', casting Richard Hatch (who played Captain Apollo in the original series) being cast as terrorist-cum-politician-cum-dictator Tom Zarek. In the episode he first appears on, both Zarek and Apollo turn their heads when someone calls out "Hey, Apollo!"
** For bonus points, he spends most of his first episode giving [[BreakingSpeech breaking speeches]] to Lee "Apollo" Adama.
*** For bonus-bonus points, the armour-piercing lecture was about what it meant to be the Great Captain Adamas son.
** This also works well with the setup that the events of BSG happen over and over again with everyone being reincarnated into a different role every time.
*** In that case James Callis as Baltar was just a Dirk Benedict stand-in...
* And Dirk Benedict, Starbuck in the original series, does a great double-take as Faceman in ''TheATeam'', when a cylon centurion passes him at the Universal Studios. The moment is preserved in the credit sequence, of course.
* In the ''Series/StargateSG1'' episode 200, Vala Mal Doran (played by Creator/ClaudiaBlack), when challenged to come up with a more obscure property to rip-off for her movie pitch, launches into a full-blown parody of ''Farscape'' which basically consists of the SG-1 cast as the Farscape crew repeating every single one of Farscape's alien curse words in the shortest span possible.
** There's also a slight subversion in that Ben Browder doesn't play Crichton in the parody--Michael Shanks does. Browder plays Stark.
*** When Vala and Mitchell first meet, Mitchell asks her if they've met before. When Vala sees Mitchel and Daniel together later, she comments about the "interesting but somewhat limited gene pool" Earth appears to have.
* A rare non-comic example: ''Series/DegrassiJuniorHigh'' and ''Series/DegrassiHigh'' would often pick which plots happened to who based on the actors' real lives. For instance, 13-year-old-Joey takes a car out for a joyride... after Pat Mastroiani, who played him, really did take the set crew's van out for a joyride. When the writers wanted to do a storyline about a kid losing his parents, they made it happen to Wheels... whose actor, Neil Hope, had lost his father years before. Kathleen was beaten by her abusive boyfriend... and the actress who played her had been date-raped at age 14. (The writers have not said whether they knew that last bit at the time they wrote the abuse story.)
* TimCurry once guest-starred in an episode of ''Series/WillAndGrace'' in which he plays a character with a feminine aspect to him (In this case, it's the character's name, Marion) flirts with several characters, makes a reference to CrossDressing, and even tries to trick one character's fiance into climbing into bed with him. [[RockyHorrorPictureShow Sounds pretty similar to a certain Sweet Transvestite, doesn't it?]]
** An episode of the short-lived 1997 series ''Over The Top'' had TimCurry dressing in drag. [[RockyHorrorPictureShow Now, why does that sound so familiar?]]
*** Speaking of ''Film/TheRockyHorrorPictureShow'', Barry Bostwick played a suspect in a ''Series/ColdCase'' episode involving a murder outside of a theater during a midnight screening of Rocky Horror.
** This is apparently his thing. He and Meatloaf also showed up as a pair of conservative straw-men trying to stop {{Glee}}'s Rocky Horror production.
** When Ed Tudor-Pole was hired as the second presenter of ''TheCrystalMaze'' after Richard O'Brien, it may have occured to the creators that three years earlier he had played Riff-Raff in the 1990 stage revival (and on the ''Rocky Horror Show: The Whole Gory Story'' soundtrack album). Or it might have been a coincidence.
* Both versions of ''Series/TheOuterLimits'' did adaptations of [[Literature/AdamLink Eando Binder's story "I, Robot"]], and Creator/LeonardNimoy appeared in both, as a reporter in the original and the robot's lawyer in the remake. Similarly, when the new ''Outer Limits'' remade "A Feasibility Study" from the original series, they cast [=David McCallum=], who had been in two episodes of the original (though not that one).
* In an episode of ''Series/HappyEndings'', Brad, played by Damon Wayans Jr., is expecting a visit from his father. When he arrives, he is played by none other than [[RealLifeRelative Wayans' father,]] Damon Wayans, Sr. (In the episode, both Wayans also make reference to the 1990s Bulls. The senior Wayans is close friends with Michael Jordan.)
* The British show ''Series/{{Doctors}}'' once had a PatientOfTheWeek who was an actor best known for his role as a mysterious time-traveller in a decades-old children's programme. Any plausible deniability that ''Series/DoctorWho'' was meant was scotched when they cast Sylvester [=McCoy=], a.k.a. the [[Series/DoctorWho Seventh Doctor]], in the role.
* In ''[[JohnLeCarre Tinker, Tailor, Soldier, Spy]]'', the head of MI-6 (one the suspects who may be the Russian [[TheMole mole]]) is played by Michael Aldridge. A few years later, one episode of ''YesPrimeMinister'' had Michael Aldridge as the head of MI-5, bringing Hacker the news that his predecessor had been a Russian mole...
** [[spoiler:Although he wasn't in the former.]]
* In the 2000 ITV telemovie of ''Literature/TheRailwayChildren'', Creator/JennyAgutter played the mother. In the 1970 film, she had played the eldest daughter.
** This leads to a truly ironic moment when Jemima Rooper, who plays Roberta, asks her mother "Didn't you use to play on railway lines when you were a kid?"
* ''Series/FTroop'':
** Sergeant O'Rourke is played by Forrest Tucker, who once portrayed an "O'Rourke" Cavalry Sergeant on ''Series/{{Gunsmoke}}''.
** Trooper Duffy (Bob Steele) is an elderly cavalryman who claims to be the sole survivor of the Alamo. Steele was previously a 1930s and '40s western star, and had once been in a movie about meeting Davy Crockett at the Alamo.
* In ''Series/ArrestedDevelopment'', after [[spoiler:firing lawyer Barry Zuckerkorn (played by Henry Winkler)]], Bob Loblaw is hired and played by Scott Baio, who also [[spoiler:replaced Winkler]] on ''Series/HappyDays''. This is specifically mentioned by Loblaw. Gets even better when you remember Creator/RonHoward is running the show.
** In one episode Barry literally jumps over a shark.
** In the episode where Tobias goes to prison to study a film role, he gets in because the warden is an appreciator of film...and played by James Lipton, who was [[http://www.youtube.com/watch?v=IVWasBau1V0 mocked mercilessly]] at the end of Creator/DavidCross' stand-up special ''The Pride is Back''.
** In an episode called "Family Ties", a woman who Michael believes to be his sister (but ultimately isn't) is played by Justine Bateman, Jason Bateman's actual sister. Also, her most famous role was in ''Series/FamilyTies''.
* In the ''Series/EightSimpleRules'' episode "Old Flame", an old boyfriend of Cate (Katey Sagal) shows up, played by Ed O'Neill (who played her husband on ''Series/MarriedWithChildren''.)
* GeorgeTakei played Rome London on ''SuiteLifeOnDeck'' in an episode that parodies ''Franchise/StarTrek''. He even played a direct descendant of London and acts very much like a young teenage girl.
** In "My Best Friend's Wedding" -- the ''Series/{{Scrubs}}'' episode where Turk and Carla get married -- Takei is cast as the priest at their wedding. At first this wouldn't seem to be a casting gag. But then, when Turk gets a call on his cell phone -- during the ceremony! -- he flips it open like an Original Series communicator. Casting Takei just so they could do that gag may be about the biggest stretch anybody has gone to for a casting gag.
*** Turk actually points out earlier in the episode that the preist looks like Sulu.
* ''Series/{{Community}}'': French Stewart appeared on the show playing a professional impersonator of French Stewart.
* In ''Series/MyNameIsEarl'' Burt Reynolds plays the character Big Chubby. His son, Little Chubby, is played by Norm [=MacDonald=]: the actor who plays Burt Reynolds in the SaturdayNightLive Celebrity Jeopardy skits. In fact, Little Chubby pretty much '''is''' the Celebrity Jeopardy version of Burt Reynolds. He even has the same laugh.
* Clive Mantel played Little John in ''RobinOfSherwood'', and so there seems to be this involved in ''Series/GameOfThrones'', where he plays Jon Umber, generally known as The ''Great''jon.
** Amusingly, in the books at least the Greatjon has a son even bigger than he is who is called Smalljon.
** Casting Creator/NatalieDormer as Margaery Tyrell seems like an example of this. Dormer played Anne Boleyn in ''TheTudors''- Anne is a beautiful young woman whose family is involved in court machinations, has a close bond with her gay brother, and ultimately finds herself tried for promiscuity before a KangarooCourt. Margaery is a beautiful young woman whose family is involved in court machinations, has a close bond with her gay brother... (you get the point) This is likely a deliberate choice as Margaery and the Tyrells are a sort of heroic subversion of the type of scheming and debauched royals who get HBO series (i.e. The Boleyns and Margaery's rival Cersei/The Lannister family).
** It's probably not an accident that Ned Stark is played by Creator/SeanBean, one of the members of [[Film/TheLordOfTheRings the Fellowship of the Ring]]. Many book critics have called ''Literature/ASongOfIceAndFire'' a SpiritualAntithesis of ''Literature/TheLordOfTheRings'', and ''Time'' Magazine famously called Creator/GeorgeRRMartin "The American [[Creator/JRRTolkien Tolkien]]". [[spoiler: When Ned's honor and idealism lead to his death at the end of Season 1--[[DecoyProtagonist and the story keeps moving without a hitch]]--it's a sure sign to the audience that they're ''not'' in Middle Earth.]]
* ''Series/SesameStreet'' had a recurring sketch that parodied ''MiamiVice'' as ''Miami Mice''. The American sketches in the German ''Sesamstrasse'' were dubbed by the same studio as ''MiamiVice'', so the voice artists who already played Crocket and Tubbs played their rodent equivilents.
* Porn stars cast as porn stars (live TV edition):
** Savanna Samson has appeared as a porn star on two TV series where TinaFey was head writer. In a 2006 episode of ''Series/SaturdayNightLive'', she was in the gag commercial for a porno called "''101 Fellations''". Three years later in the ''Series/ThirtyRock'' episode titled "Into the Crevasse", she played "Porn Liz" in Tracy's {{Rule 34}} porn video of the show.
* In the Dutch soap opera ''Goede tijden, slechte tijden'', one character, played by Ferry Doedens, is currently looking for tickets to go see ''{{Theatre/Wicked}}''. In real life, Ferry plays Fiyero part of the time.
* All over the place on ''{{Chuck}}''. Fedak and Schwartz made an effort to squeeze in appearances by as many geek culture icons as was humanly possible over the series's run, and you can ''expect'' that there will be an ActorAllusion along the way. Some notable ones:
** Scott Bakula, complete with an "[[QuantumLeap Oh boy]]!" Bakula even went meta in the network lead-in to his first appearance. When announcing ''Chuck'', he commented that he felt like he's "been here before." ''Quantum Leap'' aired on NBC (though in a different time slot, which would have made the gag even ''better''.
** Linda Hamilton at one point gives a "[[TheTerminator Come with me if you want to live]]."
** Creator/DolphLundgren quotes [[RockyIV Ivan Drago]] several times.
** StoneColdSteveAustin as a "close combat" expert.
** Chevy Chase as the narcissistic Ted Roark, and even riffs on his famous [[SaturdayNightLive Weekend Update]] CatchPhrase.
---> '''Chuck''': Roark!
---> '''Roark''': No, ''I'm'' Ted Roark, and you're the CIA agent who's in a lot of trouble.
** Creator/RobertEnglund plays a scientist who specializes in chemicals that [[Franchise/ANightmareOnElmStreet terrorize his victims]].
** [[Series/{{Smallville}} Kristin Kreuk]] appears in three episodes also featuring [[Film/SupermanReturns Brandon Routh]]. A ''Franchise/{{Superman}}'' reference was inevitable.
** SummerGlau as a KnifeNut CIA agent who has little respect for Team Bartowski. [[Creator/AdamBaldwin Casey]] doesn't know [[Series/{{Firefly}} what crew she came from or who she's worked with before]], but his friends are the best spies he's ever worked with.
* Cyndi Lauper played Avalon, a psychic in the ''{{Bones}}'' episode "Harbingers in the Fountain", [[spoiler: as well as the show's 150th episode, "The Ghost In the Machine"]]. In an earlier episode, "The Wannabe In the Weeds", Brennan sang a rousing chorus of Cyndi's biggest hit, "Girls Just Wanna Have Fun".
* Creator/AmberBenson, who played witch Tara on ''Series/BuffyTheVampireSlayer'', later played a VegetarianVampire on ''Series/{{Supernatural}}''.
** Mercedes [=McNab=] also played a vampire, after having played one on ''Buffy'' and ''Series/{{Angel}}''.
** JamesMarsters and Charisma Carpenter from both shows played witches in ''Supernatural''.
** Harry Groener who played Mayor Wilkins in ''Buffy.''
* One episode of ''Series/{{Scrubs}}'' featured four elderly doctors who had got sick at a medical convention ... played by the four leads from ''StElsewhere''.
** Speaking of, one episode of ''Series/GreysAnatomy'' featured a woman played by Sarah Chalke (Elliot from ''Series/{{Scrubs}}'') who brings in her son for treatment, and ends up correctly diagnosing his illness after the doctors couldn't find out what was wrong with him. Ironically, ''Scrubs'' [[HilariousInHindsight previously]] made fun of the idea of patients self-diagnosing using information from the internet ({{Wikipedia}} specifically). Though, this story was actually RippedFromTheHeadlines.
* ''Series/{{Psych}}'' had "This Episode Sucks" an episode which paid {{Homage}} to vampire movies featured Kristy Swanson of the original ''Film/BuffyTheVampireSlayer'' film and Corey Haim from ''Film/TheLostBoys''.
** Steve Valentine from ''Series/ImInTheBand'' also plays a rock star in "100 Clues".
** "No Country for Two Old Men", the episode that takes place largely in Mexico, features Jeffrey Tambor, who plays George Senior in ''Series/ArrestedDevelopment'', which had going to Mexico as a plot point[=/=]RunningGag.
* {{Series/CSI}}'s episode "A Space Oddity" was an extended riff on ''Franchise/StarTrek'' fandom, and featured as a major plot point the reveal of the DarkerAndEdgier version of the classic sci-fi series, to an avalanche of hatred from fans. The very first person to call out "You suck!" was none other than [[BattlestarGalacticaReimagined Ron Moore]].
* {{Series/Glee}}'s Anderson brothers. Gay Blaine is played by straight Darren Criss and straight Cooper is played by gay Matt Bomer
* ''Series/{{Frasier}}'': Notorious chauvinist "Bulldog" Briscoe played by real-life openly gay activist Dan Butler.
** Daphne's family and its multitude of inconsistent {{British Accent}}s. Particularly on the part of the [[FakeBrit Australian playing Simon]], who loves Mel Gibson and who Frasier once refers to as a "[[TheThingThatWouldNotLeave boomerang]]."
** In one episode Frasier and Niles try to help a former Shakespearian actor Jackson Hedley revive his theatrical career by producing him in a one man version of ''Theatre/{{Hamlet}}'', but [[spoiler:they realize to their horror that he's actually a terrible actor, who does a laughably overwrought performance of the play]]. The gag is that Hedley is played by Creator/DerekJacobi, an acclaimed Shakespearian actor.
* The ''[[TheFlash2014 Flash]]'' reboot has John Wesley Shipp, who portrayed TheFlash in the short-lived [[Series/TheFlash 90's live-action show]], cast as Barry Allen's [[spoiler: incarcerated]] father. It also brings back Amanda Pays, who played [=Tina McGee=], [[RoleReprisal as an older version of the character]].
* In the ''Series/InsideNo9'' episode "Last Gasp", one character mistakenly refers to a girl called Tamsin as "Tasmin". He is immediately reprimanded for the mistake by a character played by Tamsin Greig.
* Gillian Anderson was cast in ''Series/{{Hannibal}}'' as Hannibal Lecter's psychiatrist, when ''The X-Files'' had some influence from ''Film/TheSilenceOfTheLambs'' (including her character, Scully, a NaiveNewcomer like Clarice Starling).
[[/folder]]

[[folder: Music]]
* For his album "Rock Swings" PaulAnka covered BonJovi's "It's My Life" which references the song "My Way" by FrankSinatra, which Anka wrote.
[[/folder]]

[[folder:Radio]]
* In The Quandary Phase of ''Radio/TheHitchhikersGuideToTheGalaxy'', original [=H2G2=] producer Geoffrey Perkins plays Arthur's boss at BBC local radio; a character with the same relationship to Creator/DouglasAdams' AuthorAvatar as Perkins had to Douglas himself.
* In the AudioPlay/BigFinishDoctorWho audio drama ''Pier Pressure'' 1930s comedian Max Miller is played by Roy Hudd, president of the Max Miller Appreciation Society.
[[/folder]]

[[folder:Theater]]
* Cate Blanchett is currently playing the title character in an Australian production of ''Richard II''. Richard and Queen Elizabeth I have famously been compared--Elizabeth herself allegedly even said "I am Richard II; know ye not that?"
* Anne Hathaway's just-announced role as the lead in the Shakespeare in the Park production of ''Theatre/TwelfthNight'' might also qualify, though it's more of a casting pun.
** They should make a movie about Shakespeare's life just so they can cast Anne Hathaway as Anne Hathaway.
* In {{Hamlet}} Polonious has a line about having played Julius Caesar as a a student. This has led to speculation that the actor playing Polonious did indeed play Julius Caesar...and that the same actor played both Brutus and Hamlet, therefore killing Polonious twice.
* Jesse L. Martin, the original Collins in {{Rent}}, was in the RockOpera ''Bright Lights Big City'' as the protagonist's best friend, who expressed disdain for "yuppies" and enjoyed using certain, um, recreational substances.
* DarrenCriss, known for playing [[Literature/HarryPotter Harry]] in ''AVeryPotterMusical'', is to eventually take over DanielRadcliffe's role in ''HowToSucceedInBusinessWithoutReallyTrying''.
** Is that a casting gag or just unintentional? It's still awesome anyway.
* ''Theatre/ArsenicAndOldLace'' inverted this in the original stage version. The psychotic older brother berates his surgical henchman because someone said he looked like Creator/BorisKarloff. In the original Broadway cast, he was ''played'' by Boris Karloff. As the production was still making money at the time the film was set to be produced, the stage producers wouldn't allow Karloff out of his contract long enough to appear in the film version, and so the film producers had to make do with a heavily-made-up Raymond Massey.
* For the 1951 West End production of ''Theatre/AStreetcarNamedDesire'', Creator/TennesseeWilliams personally cast Vivien Leigh--who was still best known for playing [[Film/GoneWiththeWind Scarlett O'Hara]] at the time--as the mentally damaged SouthernBelle Blanch Dubois, whose inability to cope with the loss of her family's ancestral plantation [[spoiler: tragically costs her her sanity]]. The casting choice carried over to [[Film/AStreetcarNamedDesire the well-known film adaptation]] released the same year (see "Film" above).
* The 2011 production of ''Theatre/Company'' cast Neil Patrick Harris as a bachelor who strings women along and disdains marriage.
[[/folder]]

[[folder:Video Games]]
* Who's that playing übercapitalist Andrew Ryan in ''VideoGame/{{BioShock|1}}''? Why it's Armin Shimerman, who you might remember as Quark the Ferengi from ''[[Series/StarTrekDeepSpaceNine Deep Space 9]]''!
** Shimerman also voiced one the of the villains from the ''VideoGame/RatchetAndClank'' series - the main rival of a character named 'Qwark'.
** Amusingly, his AlternateCompanyEquivalent, the security-obsessed [[VideoGame/FalloutNewVegas Robert House]] is played by the same guy as Odo.
* While Creator/PatrickStewart playing the emperor may qualify as an ActorAllusion in ''VideoGame/TheElderScrollsIVOblivion'', the casting of Lynda Carter (famous for playing Series/WonderWoman) as the voices of the female Orcs and Nords certainly qualifies.
* The ''VideoGame/GrandTheftAuto'' series is rife with this trope, with Creator/SamuelLJackson, Ice-T and Peter Fonda in ''San Andreas'', Phillip Michael Thomas, Jenna Jameson and Burt Reynolds in ''Vice City'', and Michael Madsen, Robert Loggia and Joe Pantoliano in ''GTA III'', as well as pretty much every DJ on every [[GTARadio radio station]] ever since ''III''.
** James Woods as a jittery, paranoid goverment agent sure seems to fit.
* NathanFillion voices the main character in [[Franchise/{{Halo}} Halo 3: ODST]]. Who plays his character's ex-girlfriend (and boss)? His ex-girlfriend [[Series/BattlestarGalacticaReimagined Tricia Helfer]]. Who plays his squad mates? [[Series/{{Firefly}} Alan Tudyk]] [[[Film/{{Serenity}} and]] Creator/AdamBaldwin.
* GaryOldman as the Russian Commander Reznov in ''VideoGame/CallOfDuty World at War''. Oldman had previously played the Russian terrorist Ivan Korshunov in ''Film/AirForceOne''. His American counterpart is voiced by Kiefer Sutherland, of ''[[Series/TwentyFour 24]]'' fame. Sutherlands's previous voice-acting job was as the American general W.R. Monger in ''MonstersVsAliens''.
** In ''VideoGame/CallOfDutyBlackOps'', Ed Harris plays a CIA agent in the 1960's involved in many missions in Southeast Asia. In ''Film/TheRock'', he played an Marine general who was famous for his black ops exploits in 1960's southeast asia.
* Male protagonist Joshua Radcliff of ''VideoGame/SuperRobotWarsDestiny'' is voiced by Creator/YuuichiNakamura in the ''[[VideoGame/SuperRobotWarsOriginalGeneration Second Super Robot Wars Original Generation]]''. This means players will see a robot-piloting [[VisualNovel/{{CLANNAD}} Tomoya Okazaki]] (since both Tomoya and Joshua have blue hair and near-similar hairstyle), surrounded by [[Anime/MobileSuitGundam00 Gundam]] [[{{Expy}} lookalikes]] (Nakamura's role in Anime/MobileSuitGundam00 is Graham Aker who memetically [[BeamMeUpScotty shouts]] "I LOVE YOU, GUNDAM!!"), fighting creatures empowered by despair (making him an anti-[[VideoGame/BlazBlue Hazama]]), alongside [[LightNovel/OreNoImoutoGaKonnaNiKawaiiWakeGaNai an orange-haired younger sister that can't be this cute]]. For [[RelationshipVoiceActor bonus gag]], said sister is to be voiced by [[VisualNovel/{{CLANNAD}} Tomoyo Sakagami's]] [[HoukoKuwashima seiyuu]].
* In VideoGame/KingdomHeartsBirthBySleep, MarkHamill plays [[TheObiWan Master Eraqus]], [[StarWars one of the few remaining masters of an ancient, inter-world knighthood with distinctive and iconic weapons. He is struck down halfway through the game by one of his pupils who embrace the darkness in his heart, but has appeared to transcend death, at least for the time being.]]
* The ''VideoGame/GodOfWar'' series did this twice: Perseus is voiced by Harry Hamlin and Hercules is voiced by Kevin Sorbo, roles the actors previously played in the original ''ClashOfTheTitans'' and ''HerculesTheLegendaryJourneys'' respectively.
* ''VideoGame/MassEffect2'': Tricia Helfer of ''Series/BattlestarGalacticaReimagined'' voices the ''Normandy'''s AI, EDI. In ''VideoGame/MassEffect3'' [[spoiler: she gets a sexy female robot platform to travel around in]]. Several of her conversations have comments that are obvious references to her role as a Cylon, including at least once when she specifically says "By your command."
* In the Japanese version of ''VideoGame/MugenSouls'', the protagonist Chou Chou (voiced by Creator/YukariTamura), conquers and makes friends with everyone through the power of making them obey her. [[MagicalGirlLyricalNanoha Does that remind you of someone?]]
* ''Videogame/FarCry3BloodDragon'', a tongue-in-cheek AffectionateParody of [[TheEighties '80s action movies]], features a {{Badass}} [[{{Cyborg}} "Cyber-Commando"]] as its protagonist. Naturally, said protagonist is played by Michael Biehn, who made his career battling cyborgs in ''Film/TheTerminator'' and leading a platoon of {{Space Marine}}s in ''Film/{{Aliens}}''.
* In ''VideoGame/LeagueOfLegends'' many of the voice actors for the champions are similar to roles they've played in the past. The most recent one? ''Creator/DanGreen'' voices Azir, the Emperor of the Sands. Yes, Pharaoh Atem is voicing another Pharaoh.

* ''WebVideo/TheTimeGuys'' made their three-person cast a joke. One actor plays every single historical character the gang meets.
* Canadian programmer Ian Kirby, one of the PowerTrio of artists behind ''BrokenSaints'', makes a CreatorCameo on the DVD voice track as a Canadian soldier.
* In WebVideo/TheNostalgiaCritic's review of ''Film/LesMiserables2012'' makes fun of the LoveAtFirstSight trope by having that happen between WebVideo/PawDugan and [[WebVideo/VampireReviews Maven of the Eventide]]; Paul Schuler and Elisa Hansen are engaged in real life.

[[folder:Western Animation]]
* ''WesternAnimation/{{Archer}}'' has a few:
** Creator/JessicaWalter heads up the main cast as a [[RichBitch wealthy]] EvilMatriarch who has a tumultuous romantic history with a recurring character played by Jeffrey Tambor, and one of her employees is a sexually voracious CloudcuckooLander [[SexySecretary secretary]] played by JudyGreer. [[Series/ArrestedDevelopment Sounds familiar...]]
** In the episode that featured Thomas Lennon as the [[MonsterOfTheWeek villain of the week]], Archer dressed up as Terry, a recurring gay prostitute from Lennon's series ''Series/{{Reno 911}}''.
** The two-part Season 4 finale casts Eugene Mirman and Kristen Schaal as boyfriend and girlfriend. The two play a brother and sister on H. Jon Benjamin's other show, ''WesternAnimation/BobsBurgers''.
* ''WesternAnimation/ThunderCats2011''
** Snarf has gone from the original's TalkingAnimal NonHumanSidekick with a VerbalTic to a TeamPet who can only PokemonSpeak. His voice actress is Creator/SatomiKoorogi, who voiced Togepi and Pichu in the anime of ''Anime/{{Pokemon}}''.
** Larry Kenney, the voice of Lion-O in the [[WesternAnimation/ThunderCats original series]] returns to voice Claudus, Lion-o's father. Which means he also gets to be the first to say "Thunder! Thunder!! Thunder-cats! HOOOOOOOO!!"
** We now have Creator/JimCummings, the voice of [[Franchise/WinnieThePooh Tigger]] and many other cat-like characters, as Caspin, a member of the ''Tiger'' clan.
* Casting director Creator/AndreaRomano seems to have set a few of these up for the Franchise/{{DCAU}}: Music/RobZombie voicing evil god Ichthultu in ''WesternAnimation/JusticeLeagueUnlimited'', [[HRPufnstuf Billie Hayes]] playing witchy Mother Mae-Eye in ''WesternAnimation/TeenTitans'', and (most amusingly), George Lazenby as the latest King in the Royal Flush Gang in ''WesternAnimation/BatmanBeyond'':
-->'''King:''' "Do you have any idea what it's like [[Film/JamesBond living in someone's shadow?!]]"
** Not to mention NathanFillion as Vigilante... [[Series/{{Firefly}} a cowboy who flies a spaceship]] with GinaTorres' character, Comicbook/{{Vixen}}. Vigilante is also very unhappy about the events of a previous episode's war-scale crisis.
** Also Arte Johnson was brought in as Virman Vundabar, who voiced him essentially as his Wolfgang character from [[{{RowanAndMartinsLaugh-In}} Laugh-In]], complete with a "Very interesting ..."
** Another joke was the casting of the Royal Flush Gang (Justice League version). All of the voice actors cast were the ones that played the principal characters in ''WesternAnimation/TeenTitans''.
*** Speaking of which, Kid Flash and Speedy in ''WesternAnimation/TeenTitans'' have the same voice actors as their ''JusticeLeague'' counterparts.
** A somewhat obscure but particularly clever example of this was casting Fred Savage and Jason Hervey (the brothers from ''TheWonderYears'') as Hawk and Dove, only reversing the relationship dynamic by casting Savage as Hawk and Hervey as Dove.
*** Legend has it originally Savage and Hervey had the opposite roles, but for one take they decided to switch characters, and the director decided it worked better.
** She's brought in Creator/AdamWest and [[Series/{{Batman}} Julie Newmar]] to play the Waynes alongside ''WesternAnimation/BatmanTheAnimatedSeries'' alumni MarkHamill, KevinConroy and Creator/RichardMoll as TheSpectre, The Phantom Stranger and Lew Moxon for the ''WesternAnimation/BatmanTheBraveAndTheBold'' episode "Chill of the Night". Especially poetic since the Phantom Stranger (Conroy, who played Batman before) wants Batman to remain a force for justice and the Spectre (Hamill, who played the Joker before) who wanted him to become a merciless killer of criminals; they were gambling for his soul at the time.
*** For the episode "The Super-Batman of Planet X!" Kevin Conroy reprises his [[WesternAnimation/BatmanTheAnimatedSeries Batman]] role, and DanaDelany and ClancyBrown reprise their ''WesternAnimation/SupermanTheAnimatedSeries'' roles... [[RecycledINSPACE sort of.]]
*** Another ''WesternAnimation/BatmanTheBraveAndTheBold'' one: John Wesley Shipp played Barry Allen on the short-lived ''[[Series/TheFlash Flash]]'' live-action series in the 90s. In "Requiem for a Flash", he voiced EvilCounterpart, the Reverse-Flash/Professor Zoom. (It gets better: In that live-action series, when trying to get information from the bad guys, Barry once pretended to be a "Professor Zoom" who created the Flash. So he's kinda-sorta reprising the role of Professor Zoom.)
*** The ''JusticeLeagueUnlimited'' adaptation of ''ComicBook/ForTheManWhoHasEverything'' has KevinConroy voicing the mugger who shot the Waynes.
** Arguably the best casting gag of the DCAU was when Creator/AdamWest was cast to play a washed up, TypeCast actor by the name of Simon Trent, who prior resents his role as a live-action TV hero.
*** In the tie in comic ''Batman Adventures'', an in-universe example occurred as Bruce Wayne had some creative control in producing a new Grey Ghost movie and chose Simon Trent to play the mayor.
** Music/HenryRollins, an anti-authoritarian and passionate rock musician, was cast as Mad Stan, an anti-authoritarian and passionate villain with a penchant for high explosives. He even quotes part of his "Information overload" monologue as Spider from ''Film/JohnnyMnemonic''.
** In ''WesternAnimation/BatmanTheAnimatedSeries'', Thomas Wayne is voiced by Richard Moll; who also voiced Harvey Dent and was one of Bruce's few friends in Gotham. Another gag is seen by the roles of Martha Wayne and Selina Kyle/Catwoman (both of which are some of the most important women in Bruce's life; judging from The Cat and the Claw) played by Adrienne Barbeau.
** In the Batman Beyond 2-parter "The Call" which featured the Justice League, Creator/ChristopherMcDonald voiced the older Superman; [=MacDonald=] also notably voiced Superman's father Jor-El. There's also another gag in the episode with the aquatic heroine Aquagirl, who's voiced by Jodi Benson of ''Disney/TheLittleMermaid'' fame.
** For ''WesternAnimation/JusticeLeagueTheFlashpointParadox'', we've got C. Thomas Howell as Professor Zoom and Danny Huston as Sam Lane. Considering [[Comicbook/{{Flashpoint}} the comic it's based on]], this basically means [[Series/CriminalMinds George Foyet]] and [[Film/XMenOriginsWolverine William Stryker]] have decided to replace Aaron Hotchner and Wolverine as the targets of their respective torments with the Flash and Superman.
*** The same film features Sam Daly voicing Superman, whose father Tim was also known for portraying the [[WesternAnimation/SupermanTheAnimatedSeries Man]] [[WesternAnimation/SupermanBatmanPublicEnemies of]] [[WesternAnimation/JusticeLeagueDoom Steel]].
* ''WesternAnimation/TheBatman'' has this as well, but with a twist - past actors but not who you'd expect. Superman is voiced by Creator/GeorgeNewbern, the ''JusticeLeagueUnlimited'' Superman rather than the ''WesternAnimation/SupermanTheAnimatedSeries'' Superman, and he's played in the style of the Creator/ChristopherReeve Superman. TheFlash is voiced by Charlie Schlatter, who played him in a single S:TAS episode, rather than MichaelRosenbaum, who played him in JL/JLU (and a whole lot more.)
* Just before the resurgence of superhero movies stated above, StanLee has already been making cameo appearances in assorted Creator/MarvelComics animated series, specifically the ''Film/SpiderMan'' ones. The first season of ''Spectacular Spider-Man'', already has this covered. Of special note is his cameo in the 90s Fox Kid's Spider-Man - [[spoiler:as himself, when Spider-Man travels to an alternate universe, implied to be ours, where Spider-Man is a comic book character.]] He's also the janitor in ''WesternAnimation/UltimateSpiderMan'' and the mayor in ''TheSuperHeroSquadShow.''
--> Stan Lee (90s Spider-Man 'toon finale): [[spoiler:Now how do I get down from here... Maybe the ComicBook/FantasticFour will swing by...]]
** Also of note, Joan Clayton Lee, Stan Lee's wife, played the voice of Madame Web in that series. [[spoiler: So naturally, writer Stan finds Madame Web quite interesting in the finale.]]
** EdAsner was famous for his role as news editor Lou Grant (a character very similar to J Jonah Jameson) in MTM Enterprises' shows. He was eventually cast as JJ in this show.
* ''WesternAnimation/{{Gargoyles}}'' does this a lot with ''Franchise/StarTrek''. The original two antagonists were members of the TNG cast, and over the course of the series seven other primary cast members from across four ''Franchise/StarTrek'' series appeared on the show, many of them in reoccurring roles.
* David Hyde Pierce playing the role of Cecil, Sideshow Bob's brother on ''WesternAnimation/TheSimpsons'' (alluding to the show ''{{Frasier}}'', in which he played KelseyGrammer's brother). In a later episode, Bob and Cecil's dad was voiced by John Mahoney, who played Frasier and Niles' dad on ''Frasier''.
** At one point, Bart even covers Cecil's eyes with his hands and declares "Guess who?" Cecil's response is "Maris?", who's Niles' wife on Frasier.
* In ''BrotherBear'' the goofy [[CanadaEh Canadian]] moose brothers are played by Rick Moranis and Dave Thomas - the goofy Candian brothers from ''StrangeBrew'' and ''SCTV''.
* ''GIJoe'' and ''{{Transformers}}'', both being Hasbro-produced MerchandiseDriven series, tend to have a few of these. ''GIJoe'' has CoreyBurton and MichaelBell playing twins Tomax and Xamot. ''{{Transformers}}'' has them as twins Sunstreaker and Sideswipe. Many actors who have played Starscream have also played the Cobra Commander, [[TransformersAnimated Tom]] [[TomKenny Kenny]], [[WesternAnimation/BeastWars Doug Parker]], [[WesternAnimation/TransformersPrime Steve]] [[Creator/SteveBlum Blum]], and [[TransformersWarForCybertron Sam]] [[SamRiegel Riegel]] being the only exceptions.
* ''RobbieTheReindeer in Close Encounters of the Herd Kind'' casts Creator/GillianAnderson of ''Series/TheXFiles'' fame as the invading alien queen.
* When the JLA-[[{{Expy}} expies]], the SquadronSupreme, appeared on ''TheSuperHeroSquadShow'', Creator/AdamWest (who played Batman [[Series/{{Batman}} in the 60s TV series]] and the last two seasons of ''SuperFriends'') and Creator/SusanEisenberg (WonderWoman on ''JusticeLeague'', ''[[WesternAnimation/SupermanBatmanApocalypse Superman/Batman: Apocalypse]]'', and ''[[JusticeLeagueDoom Justice League: Doom]]'') were cast in the respective roles of Batman-expy Nighthawk and Wonder Woman-expy Power Princess.
* John Ratzenberger is the ''only'' actor to appear in every single Pixar movie.
* When Pat Buttram still worked for Disney, he is always cast as [[Disney/TheAristocats some]] [[Disney/RobinHood sort]] [[Disney/TheFoxandtheHound of dog]] with a Southern accent. Except in ''Disney/TheRescuers'', where he was cast as a rat with a Southern accent.
* JulieLemieux has voiced two different ([[CrossDressingVoices male]]) bat characters with a fairly similar voice: Sleepy Bat on ''{{Birdz}}'' and Batty on ''AlmostNakedAnimals'' a good 13 years later.
* Creator/GreyDeLisle plays two different feline characters named Kitty: one on ''TuffPuppy'' and the other on ''DangerRangers''. She also voiced Comicbook/{{Catwoman}} in ''VideoGame/BatmanArkhamCity'' and ''[[InjusticeGodsAmongUs Injustice: Gods Among Us]]''.
* GilbertGottfried actually voiced at least [[Disney/{{Aladdin}} three]] [[WesternAnimation/{{Cyberchase}} obnoxious]] [[MorallyAmbiguousDucktorate birds.]] (The third being the Aflac duck.)
* In ''WesternAnimation/TheLegendOfKorra'', a character named Asami is voiced by one Seychelle Gabriel, who played Princess Yue in the [[TheLastAirbender film.]] Expect to hear a line about [[MemeticMutation beliefs.]]
** In a flashback of the episode "Old Wounds", a teenage Suyin Beifong is voiced by JessieFlower, who voiced Suyin's mother Toph in the original series.
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'':
** In the episode "Super Speedy Cider Squeezy 6000," one of the villains trying to trick the Apple family out of their farm is voiced by Creator/SamuelVincent, who has had previous experience [[WesternAnimation/EdEddNEddy pulling off scams.]]
** And Discord, a very chaotic Trickster God type, is voiced by Creator/JohnDeLancie, aka [[Series/StarTrekTheNextGeneration Q]].
* When WesternAnimation/PhineasAndFerb went to Hawaii, the hotel manager was voiced by Phill Lewis, who also plays a hotel manager on [[TheSuiteLifeOfZackAndCody some]] [[TheSuiteLifeOnDeck other]] DisneyChannel shows. And since Candace decides to take time off from busting her brothers, he becomes the one running around trying to stop two boys from causing havoc...
%% ** Let's also not forget [[AshleyTisdale who plays Candace...]]
%%% Let't not use WordCruft and let's use proper ExampleIndentation. Zero-context examples are not allowed.

* When the celebrity voice actors were replaced in the transition from the ''WesternAnimation/{{Madagascar}}'' films to ''ThePenguinsOfMadagascar'', celebrity voice actor Creator/SachaBaronCohen (the voice of King Julien) was replaced by Danny Jacobs. Jacobs previously played an impersonation of Cohen's ''Film/{{Borat}}'' character in ''EpicMovie''.
* Alyssa Milano was cast as Poison Ivy in ''WesternAnimation/YoungJustice''. She starred in ''Poison Ivy II: Lily'' early in her career.
** ''Young Justice'' also has Tye Longshadow voiced by the same actor who played Long Shadow from ''Justice League.'' Both are based on Apache Chief from ''SuperFriends'' ([[DontExplainTheJoke with his size-changing power, he casts a long shadow.]] Though the YJ version basically creates giant energy astral projections of himself around him.)
** Creator/BenDiskin plays Harm, an AxCrazy villain with bizarre verbal idiosyncrasies. Just like his [[Comicbook/{{Venom}} last role]] in a Creator/GregWeisman [[WesternAnimation/TheSpectacularSpiderMan cartoon]].
** Creator/JoshKeaton plays Black Spider, a villainous CaptainErsatz of Comicbook/SpiderMan. Keaton's previous gig in a Greg Weisman show? The title role in ''WesternAnimation/TheSpectacularSpiderMan''.
** When it came time to cast TheFlash, a crime scene investigator-turned-superhero, who did they choose? Why none other than ''{{Series/CSI}}'' star George Eads!
* An episode of ''WesternAnimation/TheVentureBrothers'' featured Hank becoming a Robin-like teen sidekick to a superhero named Captain Sunshine. Who voiced Sunshine? KevinConroy. Though interestingly enough, the hero is more of a Superman parody despite the sidekick relation.
* ''WesternAnimation/AvengersEarthsMightiestHeroes'' has [[BuckyBarnes Bucky]] share a voice actor with ''the'' KidSidekick, {{Robin}}, from ''WesternAnimation/TeenTitans.'' Of course, TT Robin is a leader and no one's sidekick anymore.
* In ''WesternAnimation/AvengersAssemble'', Creator/BrianBloom plays [[SquadronSupreme a twisted, corrupt]] {{Expy}} of Comicbook/{{Superman}}. Just like in ''JusticeLeagueCrisisOnTwoEarths''!
* ''WesternAnimation/UltimateSpiderMan'' has Creator/DanteBasco playing the Scorpion, [[WesternAnimation/AvatarTheLastAirbender an exiled warrior obsessed with honor]].
** The Halloween special has the Living Mummy voiced by Oded Fehr, best known for his role in the ''Film/TheMummyTrilogy''.
** Rapper and ''Series/{{Community}}'' star [[ChildishGambino Donald Glover]] ignited an internet firestorm after he campaigned to play [[RaceLift Peter Parker]] in ''Film/TheAmazingSpiderMan'', and the ensuing racial controversy partially led to the creation of Miles Morales, the [[AffirmativeActionLegacy second]] ''Comicbook/UltimateSpiderMan''. When it came time to cast someone as Miles for the cartoon, guess who Marvel went with?
* Creator/RobertEnglund guest-starred in an episode of ''[[GreenLanternTheAnimatedSeries Green Lantern: The Animated Series]]'' as Myglom, an alien sadist [[Franchise/ANightmareOnElmStreet who torments his victims by using their own nightmares and greatest fears against them]].
* KimPossible had "The Fearless Ferrett" have Ron Stoppable as the next "Fearless Ferret," a in-joke in that Ron's VA, WillFriedle, voiced Terry [=McGinnis=] as the Future Batman in WesternAnimation/BatmanBeyond. The first Fearless Ferrett, Timothy North, was voiced by Creator/AdamWest. When Mr. North saw Kim, he then mused about "Ferret Girl"...then called her "Ferret Girl" again when he seems Kim again when The White Stripe tries to take on Ron.
** In "Steal Wheels", Ron and Felix become good friends. WillFriedle and JasonMarsden are good friends in RealLife.
* The title of the ''WesternAnimation/ChipNDaleRescueRangers'' episode "Gadget Goes Hawaiian" is an obvious play on ''Gidget Goes Hawaiian'', the second ''Gidget'' film. Gadget's Hawaiian IdenticalStranger, Lahwhinie, was voiced by Deborah Walley, who played Gidget [[TheOtherDarrin in that film]].
* In ''WesternAnimation/SanjayAndCraig'', title character Sanjay Patel is voiced by Maulik Pancholy, who previously played a character of the same name on ''Series/{{Weeds}}''.
* The writers for {{Freakazoid}} modeled one of the main villains after Khan from ''Film/StarTrekIITheWrathOfKhan''. They never really expected Ricardo Montalban to play the role.
* [[Creator/RobPaulsen Rob]] [[WesternAnimation/TeenageMutantNinjaTurtles1987 Paulsen]] appears in [[WesternAnimation/TeenageMutantNinjaTurtles2012 the 2012 Teenage Mutant Ninja Turtles series]]...as Donatello.
** And Corey Feldman, who provided Donatello's voice in [[Film/TeenageMutantNinjaTurtles two of the films]], is now [[spoiler: Slash.]]
** NolanNorth and KevinMichaelRichardson, who both had major roles in [[WesternAnimation/{{TMNT}} another Ninja Turtles project]], respectively handle duties as the show's BigBadEnsemble as the Kraang and the Shredder.
* Given the HoYay surrounding Batman and Robin in most interpretations, it's interesting that {{Nightwing}}, a former Robin in ''WesternAnimation/BatmanUnderTheRedHood'', was voiced by Creator/NeilPatrickHarris of all people.
** And since he was also the voice of Barry Allen in ''[[ComicBook/DCTheNewFrontier Justice League: The New Frontier]]'', this led to an ActorAllusion moment in ''WesternAnimation/JusticeLeagueTheFlashpointParadox'' where Barry's mom asks if he's gay.
* In ''WesternAnimation/TheLegoMovie'', Will Forte voices Abraham Lincoln. [[CloneHigh Again]].
** Superman and Green Lantern are respectively voiced by Channing Tatum and Jonah Hill, with Green Lantern constantly getting on Superman's nerves. The two played the leads in directors Phil Lord and Chris Miller's [[Film/TwentyOneJumpStreet previous film]].
* ''WesternAnimation/ScoobyDooMysteryIncorporated'':
** Creator/CaseyKasem, who was Shaggy's voice actor on the original ''WesternAnimation/ScoobyDooWhereAreYou'', has a recurring role as [[MythologyGag Shaggy's father]].
** In the episode "The Night the Clown Cried", a character voiced by Matt Lanter (who had previously voiced Anakin Skywalker in ''WesternAnimation/StarWarsTheCloneWars'') turns out to be the true identity of that episode's MonsterOfTheWeek--who is voiced by Creator/MarkHamill (Luke Skywalker in the classic ''Franchise/StarWars'' trilogy). Said MonsterOfTheWeek is also a supervillain with a MonsterClown gimmick, referencing [[WesternAnimation/BatmanTheAnimatedSeries Hamill's second most famous role]].
** The recurring character Professor H.P. Hatecraft ([[NoCelebritiesWereHarmed a thinly-veiled parody of]] Creator/HPLovecraft) is voiced by Creator/JeffreyCombs, who's best known for playing Dr. Herbert West in the film version of Lovecraft's ''Film/ReAnimator''.
* Disney's ''Main/MickeyMouseworks'' series features several shorts featuring Disney/ThreeLittlePigs. These updated cartoons feature Bill Farmer as Practical Pig and Creator/JimCummings as the Big Bad Wolf. This makes the second time they've played a {{Foil}} to one another, the first being respectively as {{Goofy}} and Pete, in tribute to the fact that these sets of characters were originally voiced by Pinto Colvig and Billy Bletcher back in the 1930's.
* In ''WesternAnimation/SpongebobSquarepants'', Creator/ErnestBorgnine and Tim Conway are paired together as the comically inept nautical-themed superheroes Mermaid Man and Barnacle Boy, referencing the duo's previous roles as the comically inept naval officers Quinton [=McHale=] and Chuck Parker in the 1960's sitcom ''Series/McHalesNavy''.
* The GrandFinale to ''WesternAnimation/StarWarsTheCloneWars'' features an appearance by the Sith Lord Darth Bane, voiced by none other than Creator/MarkHamill!
* In ''WesternAnimation/MyLittlePonyEquestriaGirls the main villain is a Shadow Archtype of main charcter Twlight Sparkle, named Sunset Shimmer. In addtion to having similar names and contrasting color schemes (that being a red/yellow version of dusk rather then purple), the gag extends all the way to their voice actresses. Sunset's actress? Twlight's singing voice: Creator/RebeccaShoichet
