* [[PlayingWithATrope Played with]] in ''Film/{{Targets}}''. Creator/BorisKarloff plays aging actor Byron Orloff, so it's Orloff who plays the Karloff roles in ''Film/TheCriminalCode'' and ''Film/TheTerror''.
* In ''Film/{{Bombshell}}'', Creator/JeanHarlow plays Lola Burns, a Hollywood movie star. At one point Lola has to do retakes for ''Film/RedDust'', which was a real movie that Jean Harlow starred in.
* Creator/KeystoneStudios silent comedy ''Film/TheKnockout'' (1914) has in one scene a clearly visible poster for Keystone production ''Caught in a Cabaret'', which starred several castmembers from ''The Knockout''.
* ''Film/StrangerThanFiction'''s entire plot is based around the aversion of this trope.
* Part One of ''Film/AtlasShrugged'' shows us that heroine Dagny Taggart has a photo of the original book's author Creator/AynRand on her computer.
* In the silent film ''Film/ShowPeople'', a satire of Hollywood movie-making, Marion Davies has a cameo as Marion Davies in addition to starring as aspiring actress Peggy Pepper. Davies as Pepper meets Davies as Davies and is not impressed.
* In ''Film/TheSevenYearItch'', when Richard Sherman is being questioned about who [[NoNameGiven The Girl]] (played by Creator/MarilynMonroe) is, he says, "Wouldn't you like to know! Maybe it's Marilyn Monroe!"
* In ''Film/{{Armageddon}}'', ''Film/PulpFiction'' exists in that universe as told in a small joke. Creator/BruceWillis and Creator/SteveBuscemi appear in both films.
* In the Creator/ArnoldSchwarzenegger flick ''Film/LastActionHero'', the real world contains the same actors and movies that we know in reality. In the [[ShowWithinAShow universe of]] ''Jack Slater IV'' (starring Schwarzenegger), Danny finds a poster for ''Film/Terminator2JudgmentDay'' with Creator/SylvesterStallone in the titular role (earlier in the film, the T-1000 makes a brief cameo), ostensibly to explain why no one thinks Slater bears an uncanny resemblance to the cyborg from the future. Which is itself a bit of a HistoricalInJoke, since Stallone was one of the actors considered for the Terminator role. And then the eponymous hero Jack meets Schwarzenegger himself, who is impressed enough to ask Jack to be his body double. Stallone hits Schwarzenegger back in ''Demolition Man'', where his character learns that Arnold was apparently President when he was in hibernation.
** ''Film/DemolitionMan'' did this itself in a scene where Simon Phoenix sarcastically calls Stallone's character ''Franchise/{{Rambo}}'', referencing a character Stallone also played.
* There's a memorable LampshadeHanging of this trope in the otherwise forgettable film ''Film/{{Stakeout}}'': To pass the time while on stakeout, Emilio Estevez and Creator/RichardDreyfuss's characters are playing a guessing game where they cite memorable lines of dialogue and quiz the other as to what movie it's from. Emilio Estevez's character, in a [[LargeHam hammish]] way, recounts the line: "''This'' was not a ''boating accident!''" Dreyfuss, after a moment's pause, replies "I don't know." The line is from ''Film/{{Jaws}}'', spoken by Matt Hooper -- a character played by Richard Dreyfuss. Apparently, they put this in the movie because [[ThrowItIn it actually happened on the set.]]
** The same gag was used in ''Film/CopOut'', when Creator/BruceWillis's character, after naming the sources of several other movie quotes, fails to recognize [[Franchise/DieHard "Yippie-ki-yay, motherfucker!"]]
* Possibly the earliest example after ''Theatre/ArsenicAndOldLace'': In the 1940 film ''Film/HisGirlFriday'', a character played by Ralph Bellamy is described as looking a lot like "that fellow in the movies, Ralph Bellamy".
* In the film ''Sex Kittens Go To College'' MamieVanDoren plays a super-smart professor who is described as looking like MamieVanDoren.
* ''Film/TheAdventuresOfBuckarooBanzaiAcrossThe8thDimension'' averts this by treating the movie as a documentary of the real life of Buckaroo Banzai, who also has his life's stories printed in comic book form and uses his fan club as a spy network.
* The original ''Film/{{Oceans 11}}'', starring the Creator/RatPack, played with this trope. In the final shot, the characters played by Music/FrankSinatra, Music/DeanMartin, Creator/SammyDavisJr, Joey Bishop, and Peter Lawford walk past the marquee of the Sands hotel. The marquee advertises the Sands' featured entertainers: Frank Sinatra, Dean Martin, Sammy Davis Jr., Joey Bishop, and Peter Lawford. Despite this, Dean Martin plays a completely different singer named Sam Harmon, who does a few shows in Vegas without anyone mentioning he looks familiar.
* The remade ''Film/OceansEleven'' flirted with this in one of the earliest scenes, when Danny and Rusty walk out of the club where they've been teaching celebrities to play poker. It's very odd to see Topher Grace and Joshua Jackson get mobbed by squealing fans, while Creator/GeorgeClooney and Creator/BradPitt stroll by unnoticed.
* ''Film/OceansTwelve'' had Tess Ocean, played by Creator/JuliaRoberts, infiltrating a museum by impersonating Julia Roberts... badly. And complains that it's "too personal" to impersonate someone else who's out there somewhere. And then she has to interact with several other celebrities like Bruce Willis who know Julia Roberts. The fact that Danny Ocean, played by Creator/GeorgeClooney, couldn't do the same implies that this is a case of OneShotRevisionism.
* Similar to the Julia Roberts example above: as a running gag in ''Film/TheCannonballRun'', eccentric competitor Seymour Goldfarb Jr. obsessively impersonates Creator/RogerMoore, both to attract women and to justify his use of 007-style gadgets to get an edge in the race. Goldfarb, naturally, is played by Roger Moore... who sends up both his actual celebrity status ''and'' his past in-character behavior as Film/JamesBond. They could only hint at Bond, though, because they couldn't get permission to actually use Bond's name.
* Several examples from the ''Film/BackToTheFuture'' series:
** Huey Lewis makes a cameo appearance as an audition judge, but Marty has a Music/HueyLewisAndTheNews poster on his bedroom wall. The song Marty and his band play for the judges in this scene is a version of "The Power of Love", a song Huey Lewis wrote and recorded specifically for the film and which is featured prominently in the soundtrack. And Marty's clock radio plays the Huey Lewis song "Back in Time", although not the bits of the song that directly reference the film.
** The Cafe '80s scene in ''Film/BackToTheFuturePartII'' shows brief clips of ''Series/FamilyTies'' and ''Series/{{Taxi}}'' -- featuring Creator/MichaelJFox and Creator/ChristopherLloyd, respectively. However, whether the actors were featured in the shows of the universe is subject to debate.
** ''[[WesternAnimation/BackToTheFuture Back To The Future: The Animated Series]]'' does it too; Marty sarcastically claims to be Michael J. Fox (to which Verne notes a resemblance), and a brief shot of a movie theater marquee in Hill Valley lists ''Film/BackToTheFuture'' as a current attraction.
* In ''Film/LoveActually'', Creator/LiamNeeson's character makes several jokes about having Claudia Schiffer appear and start a relationship with him. Towards the end of the movie he meets a woman named Carol, played by Claudia Schiffer.
* In ''Film/LooneyTunesBackInAction'', DJ Drake claims to have been Creator/BrendanFraser's stunt double in ''Film/TheMummyTrilogy''. At the end of the movie, Drake runs into the real Fraser (also played by Fraser, obviously) and punches him in the face for acting like a dick.
-->'''DJ:''' (to Daffy) Have you seen those ''[[Film/TheMummyTrilogy Mummy]]'' movies? I was in them more than Brendan Fraser was!
* ''Film/FoolishWives'' by Creator/ErichVonStroheim features a character reading a book called ''Foolish Wives'' by Erich von Stroheim.
* The novel ''Literature/BridgetJones' Diary'' is based in part on the plot of ''Literature/PrideAndPrejudice'' -- the love interest is named Mark Darcy, and the title character is obsessed with Creator/ColinFirth's portrayal of the original Mr. Darcy in the 1995 BBC adaptation of the Jane Austen novel. In the film, ''Pride & Prejudice'' isn't mentioned, but Mark Darcy is played by... Colin Firth. A scene from the book's sequel (but [[DeletedScene deleted from the movie]]) shows Bridget interviewing Colin Firth.
* ''Film/SpiderMan1'':
** In the novelization of the film, Mary Jane has seen ''Film/InterviewWithTheVampire'' and was creeped out by the little girl who played Claudia. Both were played by Creator/KirstenDunst.
** Aunt May tells Peter "You're not Franchise/{{Superman}}, you know!", and Peter half-jokingly yells out "ComicBook/{{Shazam}}!" and [[Franchise/{{Superman}} "Up, up, and away!"]] when he's trying to figure out [[HowDoIShotWeb how to fire his web]]. This seems to imply that whether or not there are Creator/MarvelComics in this universe, Creator/DCComics certainly exist.
* [[ZigZaggingTrope Zig-Zagged]] in Creator/KevinSmith's ''Film/JayAndSilentBobStrikeBack'':
** The film is about Jay and Silent Bob getting a movie made about them (and not getting paid for it). They discuss who should star in the movie. Ben Affleck's character Holden suggests that because it's Miramax, it's probably Creator/BenAffleck and Creator/MattDamon.
** Affleck then shows up later as himself, along with Damon, shooting ''Film/GoodWillHunting 2: Hunting Season''. Damon mentions that Affleck talked him into doing ''Film/{{Dogma}}'', a previous Kevin Smith film in which Jay and Silent Bob also appear as important characters. Interestingly, on the DVD commentary the writers mention that [[WhatCouldHaveBeen they considered]] having different actors play Affleck and Damon, including the Wayans brothers.
** For the hat trick, at the very end, two characters compare ''Film/{{Mallrats}}'' and ''Film/ChasingAmy'' -- the latter of which had Affleck playing the same character he does in ''Film/JayAndSilentBobStrikeBack''. This scene also features the mind-screwery of Joey Lauren Adams' character Alyssa Jones, who in ''Chasing Amy'' mentions having sex with Gwen Turner -- a character Adams played in ''Mallrats''.
** Even outside Franchise/TheViewAskewniverse, things get strange. Creator/MarkHamill, who played in ''Film/StarWars'', shows up as himself and references the film. Creator/CarrieFisher, who also played in ''Film/StarWars'', shows up to play a nun.
* From ''Franchise/JamesBond'':
** The original [[Literature/JamesBond Bond novels]] describe Bond as looking like a cross between Hoagy Carmichael and Creator/DavidNiven. The latter got to play him in ''Film/CasinoRoyale1967''.
** The film ''Film/CasinoRoyale2006'' faithfully reproduces a scene from [[Literature/CasinoRoyale the original novel]] where James Bond orders a very specific kind of martini -- three parts Gordon's gin, one part vodka, a half part Lillet. In the real world, this drink, called a "Vesper" after Bond's love interest in the novel, has become well-known enough to have an entry on [[Wiki/{{Wikipedia}} That Other Wiki]], and a bartender presumably wouldn't need to be instructed on how to make one. But in the movieverse, the James Bond novels don't exist, so presumably nobody has ever heard of a Vesper martini.
* ''Film/BlazingSaddles'' happily [[BreakingTheFourthWall breaks the fourth wall]] with no regard for the celebrity paradoxes it creates. Among other things:
** Taggart yells "I'm working for Creator/MelBrooks!" -- who was indeed the writer and director of the film, but also appears in the movie in two different roles.
** Hedley Lamarr, Sheriff Bart, and the Waco Kid all break out of their film set and go to the theater to see ''Film/BlazingSaddles''.
** The famous RunningGag regarding Hedley Lamarr's name is {{lampshade|Hanging}}d by the governor when he points out that it's 1874, meaning that "You'll be able to sue ''Creator/{{he|dyLamarr}}r!''"
* Creator/MelBrooks did it again in ''Film/{{Spaceballs}}'', when the villains try to track the heroes by picking up a VHS of ''Spaceballs'' and watching it to see where they wind up, HandWaving the technology that allows you to see forward in time like that (sort of).
* The ''Franchise/{{Scream}}'' franchise made it big in part because it was a horror movie that acknowledged that people will know about horror movies and thus display at least some GenreSavvy, compared to all the horror films that take place in universes where apparently [[GenreBlindness no such things exist]].
** ''Film/{{Scream 2}}'' has the [[ShowWithinAShow film-within-a-film]] ''Stab'', which was based off the events of ''Scream''. Different actors portray the characters this time around, but having Tori Spelling play Creator/NeveCampbell's character Sydney finishes a BrickJoke where Sydney hopes to be played by Creator/MegRyan, but [[TemptingFate knowing her luck she'd probably get Spelling]]. Creator/CourteneyCox's character also mentions that David Schwimmer and Creator/JenniferAniston (two of Cox's co-stars on ''Series/{{Friends}}'') are in ''Stab'' as well.
** In ''Scream'', a VHS copy of the movie ''Film/{{Clerks}}'' can be seen in the party scene at the end of the movie. In ''Film/{{Scream 3}}'', ''Clerks'' characters Jay and Silent Bob appear as in-universe characters who take a tour of the movie studio and run into Gale Weathers. To top it off, ''Scream'' director Wes Craven appears in ''Film/JayAndSilentBobStrikeBack'' as the director of a fictional version of ''Scream 4'' that has nothing to do with the real ''Film/{{Scream 4}}'' that was made years later.
* Like most rapper-actors, Method Man can most often be found portraying gang members and fictional rappers in his numerous television and film roles. You have to wonder if any of them listen to Music/{{Wu Tang|Clan}}.
** In ''Film/HowHigh'', in which Method Man plays one of the two main characters, another character mentions that he listens to Wu Tang Clan on his headphones.
** In ''The Wackness'', he plays a drug supplier who gives the main character a copy of [[Music/TheNotoriousBIG Biggie's]] ''Ready to Die'', an album he himself was featured on.
* In ''Literature/FearAndLoathingInLasVegas'', while walking through a rock club in a flashback within the film, [[spoiler:Creator/JohnnyDepp as Thompson narrates, "There I was...," suddenly stopping when he spots the ''real'' Dr. HunterSThompson in the shot, exclaiming, "Mother of God, there I am! Holy fuck..."]].
* In ''Film/CrankHighVoltage'' a witness is asked to describe Creator/JasonStatham's character, Chev Chelios, and refers to him as "like the man from those ''[[Film/TheTransporter Transpointed]]'' movies." Guess who plays the Transporter.
* Creator/NatalieWood appears AsHerself in ''Film/TheCandidate'', in a scene where she meets Senate nominee Bill [=McKay=], played by Creator/RobertRedford, and says she likes everything he stands for. She does not wonder why Bill looks so much like her co-star in ''Inside Daisy Clover'' and ''This Property Is Condemned''.
* ''Film/MyFavoriteBlonde'' has one scene in which Larry (Creator/BobHope) turns on the radio and hears Bob Hope's radio show.
--> '''Larry:''' I can't stand that guy.
* Subverted in ''Film/{{Airplane}}'', in which Kareem Abdul-Jabbar, then a basketball player for the Los Angeles Lakers, played the co-pilot Roger Murdoch. The kid visiting the cockpit recognizes Kareem and tells him how much he admires him; Murdoch denies that he's Kareem. Then the kid tells him [[BrilliantButLazy what his dad thinks of him as a player]], prompting Kareem to [[BerserkButton angrily defend himself]]. By the time "Murdoch" passes out and is dragged out of the cockpit, he's suddenly in full Laker uniform (including the iconic goggles he played in). The writers did this because the film they were spoofing, ''Zero Hour'', had football star Elroy "Crazylegs" Hirsch playing the pilot.
** MTV reversed this scene (right down to the dialogue) in their first ''Rock and Jock Basketball'' game, where a fan mistakes Kareem for the famous pilot Roger Murdoch.
* Played with in ''Film/{{Hellboy}}'', which is based on the [[ComicBook/{{Hellboy}} comics]]: the eponymous demon is actually a pretty popular myth, on par with stuff like Yeti and Bigfoot (though perhaps slightly more believed), and has comics based on him, prompting a supporting character, upon meeting him, to be surprised that his comics hero from childhood is real, and for Hellboy himself to comment that he dislikes the comics as they get his eyes wrong.
** On the other side of the canon, the graphic novel ''Lobster Johnson: The Iron Prometheus'' has articles detailing the title character's in-world media appearances, all of which were [[AdaptationDecay highly inaccurate]] and SoBadItsGood ''at best''. One of the articles mentions that "acclaimed Mexican director Creator/GuillermoDelToro" had expressed interest in remaking the largely inexplicable Mexican films (the ones that portrayed Lobster Johnson as a MaskedLuchador).
** Referenced in ''Webcomic/AbeAndKroenen'', where Kroenen mentions that the Hellboy clone had gotten himself a job as a Hellboy impersonator. Abe asks if the clone has a partner impersonating him and Kroenen mentions that there is an Abe impersonator "but she's not very good at it."
* Robby the Robot in ''Film/ForbiddenPlanet'' was the [=R2D2=] or [=C3PO=] of its day and has been used almost like a live action {{animated actor|s}}, making this one of the few times this trope applies to a nonhuman character. The Blu-Ray/HD home video version of the movie includes a ''Thin Man'' episode and a movie ''The Invisible Boy'' where Robby appears, under his own name; needless to say, characters are astonished by the robot but never associate it with a movie.
* Creator/ClintEastwood seems to like this trope:
** At the end of ''Film/AnyWhichWayYouCan'', the cast is musing over their drinks in a bar, where the lounge singer is singing the song, "You're Just a Coca-Cola Cowboy," with the line "You've got a sexist smile and Robert Redford hair." The ''actual'' line in the song is "You've got an Eastwood smile and Robert Redford hair."
** Creator/ClintEastwood was also in a short Italian movie in which he played a LazyHusband, while his frustrated wife attempted to get him to take her out to see ''Film/AFistfulOfDollars''. Perhaps a legitimate artistic point?
** ''Film/DirtyHarry'' intervenes to stop a bank robbery. A nearby theatre is playing ''Film/PlayMistyForMe''.
* From ''Franchise/StarTrek'':
** In ''Film/StarTrekTheMotionPicture'', we're shown a wall of pictures of all the vessels ever called the ''Enterprise'', including the Federation flagship -- and the real life NASA Space Shuttle Orbiter. However, the real ship only got its name because of ''Star Trek'' (even though it wasn't the first vessel of ''any'' kind to be called ''Enterprise''). In the ''Star Trek'' universe itself, it's the other way around -- the flagship was named after the real-life orbiter.
** ''Film/StarTrekIVTheVoyageHome'' was largely a FishOutOfTemporalWater comedy in which the ''Enterprise'' crew goes back to 1986, an era by which ''Star Trek'' was so influential it would be hard to encounter anyone who wouldn't recognize them.
** In the 2009 ''Film/StarTrek'' reboot, a young AlternateUniverse Kirk listens to "Sabotage" by the Music/BeastieBoys, a band who in RealLife would make frequent reference to ''Star Trek''.
* ''Film/FinalDestination''. It's VeryLooselyBasedOnATrueStory. Nobody remarks about the extremely similar 747 crash four years earlier.
* A particularly complex example is ''Film/ManOnTheMoon'', a {{Biopic}} of Creator/AndyKaufman. Creator/DannyDeVito plays Kaufman's agent George Shapiro. [=DeVito=] was also a producer of the film, and explained in a making-of short that he had wanted to play Shapiro from the beginning -- not realizing that this paradox would be created because he had played Louie [=DePalma=] on ''Series/{{Taxi}}'', which was Kaufman's biggest mainstream success and thus had to be brought up in the film. [=DeVito=]'s characters in the movie and ''Taxi'' were visually and dramatically distinct enough that he might have been able to play them both, and they may have been going this way in early drafts. Eventually, though, they chose to write out Louie (and thus the real [=DeVito=]) from the ''Taxi''-related scenes. At least one critic admitted [[FridgeLogic he hadn't noticed Louie's absence until later]], perhaps in part because most of the other ''Taxi'' cast members appeared as themselves.
* The first scene of ''Film/TangoAndCash'' has Tango reply to a uniformed officer's claim that Tango "thinks he's Rambo" with "[[http://www.agonybooth.com/agonizer/Tango___Cash_1989.aspx Rambo is a pussy.]]" Creator/SylvesterStallone played both Rambo and Tango.
* ''Film/{{Adaptation}}'', starring Creator/MerylStreep and Creator/NicolasCage, is a cross of this and PostModernism. Cage plays screenwriter Creator/CharlieKaufman, the film's actual playwright. He's struggling to adapt Susan Orlean's book ''The Orchid Thief'' to film -- the book and author are real, although Streep plays Orlean. Kaufman even visits the set of the previous film he wrote, ''Film/BeingJohnMalkovich''. And the screenplay the film's Kaufman is written turns out to be [[spoiler:the screenplay for the actual film you are watching]].
* Used to effect in ''Film/FightClub''. When Marla and the Narrator are talking outside a movie theatre, the movie playing is ''Film/SevenYearsInTibet'', starring Creator/BradPitt, who also plays Tyler Durden in ''Fight Club''. Given that this scene [[spoiler:takes place after the Narrator discovers that Tyler is his split personality]], the film serves as [[spoiler:a subtle reminder that Tyler is invisibly present in this scene]].
* In the 2007 ''Film/StTrinians'':
** Creator/ColinFirth plays the Minister for Education -- which means that we get jokes about a dog named "Mr. Darcy" and a reference to ''Film/GirlWithAPearlEarring''.
** Additionally, Colin Firth himself gets a mention. That mention being that his character in ''Girl with a Pearl Earring'' was right to want to shag the title model.
** When Headmistress Fritton (Rupert Everett) encounters Geoffrey Thwaites (Firth) for the first time in years, they reminisce that they first met so long ago, it seems like it was "Another Country". This happens to be the title of the 1984 film in which they played roommates.
* From ''Film/{{Batman}}'':
** Knox is jokingly handed a goofy cartoon of a bat in a suit, which happens to be signed by Batman's original creator Bob Kane.
** ComicBook/TheJoker and his gang enter the Flugelheim Museum carrying a boombox that plays "Partyman", a song Music/{{Prince}} wrote for the "pop" soundtrack and which includes sound clips from ''Film/{{Batman}}'' itself. The Joker spots Vicki Vale and stops the recording seconds before it would have played one of Vicki's lines from later in the film. When the Joker turns the tape back on, it's suddenly playing a different song.
* In ''Shrink'', Creator/RobinWilliams plays actor Jake Holden. Another character in the film is a fan of classic movies, and in one scene she's watching ''Film/TheGraduate'', so we know Creator/DustinHoffman exists as himself in the film. The question is: did Jake Holden star alongside him in ''Film/{{Hook}}'' in this universe? Was he also the star of ''Film/GoodMorningVietnam'', ''Film/MrsDoubtfire'', and many others? He must have been, because no one comments on how he looks just like Robin Williams.
* In ''Film/{{Zombieland}}'', [[spoiler: Creator/BillMurray]] cameos AsHimself. He doesn't seem to notice how much Tallahassee looks like [[spoiler:the guy he starred with in ''Film/{{Kingpin}}''.]] There's also a poster for ''Film/TwoThousandTwelve'', a film in which Creator/WoodyHarrelson starred.
** Particularly fun is the use of footage from the Sylvester Stallone episode of ''Series/TheMuppetShow'', with Kermit dubbed over to say Rocky's name instead.
* In ''D3: Film/TheMightyDucks'', team captain Charlie references the Anaheim Mighty Ducks, a pro hockey team named after them. Why a pro team would name itself after a youth team -- even one that did win the under-18 world championship in the previous film -- is not addressed. In RealLife, there was an NHL team called the Mighty Ducks of Anaheim, which was owned by Disney and named after the ''Mighty Ducks'' movie. (When Disney sold the team, it was rechristened Anaheim Ducks, mitigating the connection.)
* In ''Film/AllAboutLilyChouChou'', one of the boys points out that his friend's mother looks just like Izumi Inamori. This makes sense considering who plays the part.
* In ''Film/RosemarysBaby'', Rosemary tells Terry, the girl she meets in the basement laundry, "I thought you were Victoria Vetri, the actress." Of course, Terry is played by Victoria Vetri, using another name. In the book, Rosemary briefly mistakes Terry for Anna Maria Alberghetti. Alberghetti was about thirty at the time and looked younger; she could have played Terry, but perhaps they couldn't get her.
* ''Film/EvanAlmighty'' uses the LenoDevice, with ''Series/TheDailyShow'''s Jon Stewart commenting on the situation. Oddly enough, he fails to notice that the title character, up until recently, strongly resembled former correspondent and close personal friend of his Creator/SteveCarell. There's also a movie theatre marquee advertising ''Film/TheFortyYearOldVirgin''.
* At one point in the Creator/FritzLang film ''Spies'', the protagonist runs by a wall covered with posters for Lang's previous film, ''Film/{{Metropolis}}''. So presumably, in this version of Berlin, Fritz Lang and Thea von Harbou exist but aren't working on ''Spies''. Fair enough. However, nobody seems to notice that the wheelchair-bound criminal mastermind [[spoiler: or the clown he often disguises himself as]] bears an uncanny resemblance to Rudolf Klein-Rogge, who played the mad scientist Rotwang in ''Metropolis''. Oh well, foreign agents probably don't go to the movies much anyway.
* In ''Film/TheATeam'', Hannibal is played by Liam Neeson. At one point, the A-Team needs to get through airport security, so they all dress in disguise (much like [[MythologyGag in the original show]]). Face is a beatnik, Murdock is a rabbi, B.A. is an African in tribal dress (HilarityEnsues), and Hannibal is... Creator/LiamNeeson. Isn't he trying to ''sneak'' past airport security?
* In ''Film/{{Blade}} Trinity'', the Nightstalkers use ''Comicbook/TheTombOfDracula'' to show the Daywalker who the BigBad is. The character Blade first appeared in ''The Tomb of Dracula'' #10.
* Creator/StanLee is known for cameos in movies based on his creations, sometimes credited AsHimself. Although he's rarely mentioned by name in these films, he does exclaim, "I'm ''Stan Lee''!" when trying to crash Reed and Sue's wedding in ''Film/{{Fantastic Four|2005}}: Rise of the Silver Surfer''.
* Creator/MichaelBay liked doing this in his ''Film/{{Transformers}}'' films:
** In the first film, ''Film/{{Armageddon}}'' is mentioned, which Bay also directed. Toys such as "Furby" and "My Little Pony" also appear; these are made by Hasbro, who also makes Transformers toys.
** In [[Film/TransformersRevengeOfTheFallen the second one]], Sam scribbles on a poster for ''Film/BadBoys II'', another film Bay directed.
** In [[Film/TransformersDarkOfTheMoon the third one]], Wheelie is watching an episode of the orginal ''[[Series/StarTrekTheOriginalSeries Star Trek]]'' ("it's the one where Spock goes nuts"). Sentinel Prime appear later in the film, voiced by Spock himself, Creator/LeonardNimoy.
** In ''Film/TransformersAgeOfExtinction'', one of the voice clips Bumblebee uses is "I am calm" from ''Film/TheBigLebowski'', said by the character Walter Sobchak. Sobchak was played by Creator/JohnGoodman, who voices Autobot Hound in the film.
* In ''Film/EagleEye'', posters for ''Film/{{Disturbia}}'' can be seen in the Circuit City store. ''Disturbia'' was the previous project directed by DJ Caruso and starring Creator/ShiaLaBeouf, which then begs the question why nobody noticed that Jerry looks a lot like Shia.
* In ''Film/IndianaJonesAndTheLastCrusade'', this is done with a landmark rather than a celebrity. The film uses the Petra ruins in Jordan as the entrance to the temple at the end. However, there is nothing apart from solid rock behind the facade in Petra, and the context in which it appears in the film would imply that the actual ruins do not exist in the movie's reality.
* In ''Film/{{Enchanted}}'', while Prince Edward, played by James Marsden, is atop a bus in Times Square and impaling it (ItMakesSenseInContext), a billboard for ''Film/SupermanReturns'', in which Marsden appears, can be seen behind him. There are also billboards for ''Theatre/{{Wicked}}'' and ''Theatre/{{Rent}}'', both of which star Idina Menzel, who also has a supporting role in ''Enchanted.''
* In ''Film/HowToMarryAMillionaire'', main character Schatze Page, played by Creator/LaurenBacall, tries to reassure her older beau, played by Creator/WilliamPowell, that young women happily marry older men all the time: "Look at Roosevelt, look at Churchill, look at old fella what's his name in ''Film/TheAfricanQueen''." Which raises the question -- what younger woman is the "old fella in ''The African Queen''" married to if it isn't Lauren Bacall?
* In ''Film/AceVentura: When Nature Calls'', Ace Ventura (Creator/JimCarrey) mentions ''Film/TheShawshankRedemption'' in one scene. Bob Gunton is featured in both of these movies as different characters.
* ''Film/{{Fanboys}}'' is a gleeful celebration of this trope. Although it centers around a group of ''Franchise/StarWars'' fanboys trying to get a sneak peek at ''Film/ThePhantomMenace'', there are a number of cameos from ''Star Wars'' actors, including Creator/CarrieFisher as a doctor, Creator/BillyDeeWilliams as a judge, and Creator/RayPark as a security guard.
* ''Film/StayTuned'' stars Creator/JohnRitter as a TV lover who's TrappedInTVLand. In one instance, he inadvertently finds himself on the set of ''Series/ThreesCompany'', a show in which Ritter played a main character. The others mistake him for the character he played.
* At one point in ''Film/JohnnyMnemonic'', there's an extended shot of the back of Music/HenryRollins' head, and the small Music/BlackFlag tattoo on his neck is prominently visible.
* Played with in the Polish movie ''[[http://www.imdb.com/title/tt0338086/ Haker]]'', where one of the characters, played by Bogusław Linda, complains about looking just like his actor and being mistaken for him.
* ''[[Film/TheBeastmaster Beastmaster 2: Through the Portal of Time]]'' shows what happens when you [[AvertedTrope avert]] this trope. The eponymous Beastmaster, Dar, winds up in 1990's America, and as the car he's in is driving down a street, he sees a movie theater showing that they're playing ''Beastmaster 2: Through the Portal of Time.'' Dar looks as confused as the audience is.
* A rather funny nod is made at the beginning of ''Literature/AboutABoy'', when its young protagonist Marcus wishes in voiceover that he was “as rich as Haley Joel Osment from ''Film/TheSixthSense''” so that he could afford a private tutor and avoid having to go to school where he’s being bullied. Marcus’ mother Fiona in ''About A Boy'' is played by Toni Collette, who also played Haley Joel’s mother three years earlier in ''The Sixth Sense''.
* In the British behind-the-scenes documentary ''Behind the Magic'', which aired before the release of ''[[Film/HarryPotter Harry Potter and the Deathly Hallows Part I]]'', Creator/DanielRadcliffe -- who plays Harry -- mentioned that the scene set in a café was shot in a real café, with walls that were covered in posters for West End plays and musicals. He decided to add a couple more – all of which featured pictures of himself as the lead in ''Theatre/{{Equus}}'' from a few years earlier.
* In ''Film/CedarRapids'', [[BlackAndNerdy Ronald Wilkes]] is a fan of "[[InsistentTerminology the HBO program]], ''Series/TheWire''". Wilkes' actor, Isiah Whitlock, Jr., played State Senator [[SleazyPolitician Clay Davis]] on that show.
* Much of the oeuvre of Creator/JohnHughes takes place in [[TheVerse a shared universe]] called the "Shermerverse", all of which feature the same high school. This causes issues sometimes:
** Both ''Film/TheBreakfastClub'' and ''Film/SixteenCandles'' take place at that school, and both prominently star Creator/MollyRingwald and Creator/AnthonyMichaelHall -- who both play completely different characters in each film. One wonders how two girls who look exactly the same could run in completely different social circles and never be mistaken for each other, or how Farmer Ted could never meet fellow geek Brian Johnson.
** In ''Film/PlanesTrainsAndAutomobiles'' Neal's wife is seen watching ''She's Having A Baby'', another John Hughes film. This raises the question of whether or not Hughes himself exists in the Shermerverse, and if he wrote and directed any respected and memorable teen films there.
* In the 2002 adaptation of ''[[Film/TheTimeMachine2002 The Time Machine]]'', a holographic museum tour guide in the protagonist's future knows not just about the novel and its author Creator/HGWells, but even sings a line from the (in real life non-existent) [[ShowWithinAShow Broadway musical]]. Adding to the paradoxical madness is that the film was directed by Wells' real-life great-grandson.
* The [[SettingUpdate 2000 film]] of ''Theatre/{{Hamlet}}'' presents [[ShowWithinAShow "The Mousetrap"]] as Hamlet's experimental student film. For the [[CatchTheConscience crucial imagery]], he uses clips from an old black-and-white silent movie which in reality is obviously another production of ''Hamlet''.
* In the UsefulNotes/{{Bollywood}} movie ''Vaah Life Ho Toh Aisi'', Sanjay Dutt plays the God of Death, Yamraj. The other characters mistake him for Sanjay Dutt (or other characters he played). Sanjay Dutt himself appears later in the film for a cameo in which he's mistaken for Yamraj.
* {{Invoked|Trope}} with Music/JelloBiafra's [[https://www.youtube.com/watch?v=WyKzdvZU3pg cameo]] in ''Film/{{Tapeheads}}''. He plays an FBIAgent arresting the main characters on obscenity charges, a CastingGag referencing a famous [[http://en.wikipedia.org/wiki/Dead_Kennedys#Frankenchrist_and_obscenity_trial_.281985.E2.80.931986.29 obscenity trial]] involving the artwork to the Music/DeadKennedys' ''Music/{{Frankenchrist}}''. Then he gets the line "Remember what we did to Jello Biafra?".
* In ''WesternAnimation/AGoofyMovie'', Max and Goofy play Twenty Questions (well, more like Goofy was playing and Max was ignoring him), and it's revealed that Goofy was thinking of Creator/WaltDisney. So if Mr. Disney existed in this universe, then did he make any WesternAnimation/{{Goofy}} cartoons?
* ''Film/BeingJohnMalkovich'' plays with this trope. While characters recognize Malkovich ([[AsHimself who is playing himself]]), they can't seem to correctly identify which movies he was in.
* ''Film/{{S1m0ne}}'' mentions Creator/MerylStreep and Music/{{Madonna}} and incorporates elements of both actresses into Simone - which makes one wonder how Al Pacino acted with both of them in ''Theatre/AngelsInAmerica'' and ''Film/DickTracy'' respectively.
* In ''Dick Tracy Meets Gruesome'', Dick's sidekick Pat says (referring to Gruesome), "He's weird. If I didn't know better, I'd say we were dealing with Creator/BorisKarloff." Guess who plays Gruesome.
* In the 2011 film ''Film/{{Warrior}}'', The UFC exists in this world. Several UFC fighters appear as themselves, while other current and former UFC fighters appear as fictional characters.
* In ''[[Film/RockyAndBullwinkle The Adventures of Rocky and Bullwinkle]]'', as Karen is being arrested (thanks to Boris and Natasha), Rocky protests that she's an FBI agent, to which the officer replies "Yeah, [[AndImTheQueenOfSheba and I'm John Goodman]]". Guess who plays him.
* The ''Film/{{SWAT}}'' movie has a rather bizarre example of this. The [[Series/{{SWAT}} original TV series]] clearly exists in the movieverse; the team [[ThemeTuneCameo sings the theme tune]] when they pass the SWAT test, and Boxer is seen watching a DVD or rerun of the show. And yet somehow nobody noticed that their team has the exact same names as the TV show team, or that Deke's father bears a remarkable resemblance to the original Deke from the TV show.
* In ''Film/TrueRomance'', Clarence mentions ''Film/TheDeerHunter'', a film starring Creator/ChristopherWalken. However, Walken also appears in ''True Romance'' as Vicenzo Conccotti.
* ''Film/TheManWhoKnewTooMuch'' had most of its score composed by Music/BernardHerrmann. He also appears during the climax AsHimself, conducting an orchestra in performing the "Storm Clouds Cantata" (an instrumental actually composed by someone else).
* The K-Horror film ''[[Film/WhiteTheMelodyOfTheCurse White: The Melody of the Curse]]'' features K-Pop group After School playing a supporting role as a K-Pop group called "Pure". They open the film by performing After School's real-life song "Bang", but with any mention of After School in the lyrics edited out.
* ''[[Film/ChildsPlay Seed of Chucky]]'' is all about this, as Chucky and Tiffany are revived as prop dolls used for a film adaptation of them, and Tiffany (voiced by Jennifer Tilly) attempts to transfer her soul into the real-life Jennifer Tilly's body.
* In ''Film/WhiteHouseDown'', tour guide Donnie makes reference to the White House being destroyed in ''Film/IndependenceDay'' -- which was directed by ''White House Down'''s director Creator/RolandEmmerich.
* In ''Film/{{Dracula 2000}}'', Lucy stands in front of a row of Vitamin C [=CDs=] at her workplace, the [[ProductPlacement Virgin Megastore]]. Lucy was played by Colleen Fitzpatrick, aka pop singer Vitamin C.
* In ''Disney/MeetTheRobinsons'', Wilbur tries to cover up the real identity of his father Cornelius Robinson by telling Lewis that he looks like Tom Selleck. We later meet Cornelius near the end, and he's voiced by Tom Selleck. When the film was dubbed in other languages, Wilbur says that his father looks like whatever actor voices him in that version.
* The 2013 dark comedy ''Film/TheFamily'' has the main character (a former gangster played by Creator/RobertDeNiro) watch the movie ''Film/{{Goodfellas}}'' in which De Niro also had a starring role.
* In ''Film/LoveActually'', the Harry Potter-films exist, but Creator/AlanRickman, Creator/EmmaThompson and Creator/BillNighy all appear in the film. Who replaces them as Severus Snape, Sybil Trelawney and Rufus Scrimgeour is never touched on.
* In the famous opening scene of ''Film/ReservoirDogs'', where the robbers have a SeinfeldianConversation about [[FreudWasRight the true meaning]] behind Music/{{Madonna}}'s "Like a Virgin", nobody seems to notice that Madonna's former brother-in-law is sitting at the table sipping coffee; "Nice Guy Eddie" is played by Chris Penn, the younger brother of Madonna's ex-husband Creator/SeanPenn.
* In ''Film/TheGoonies'', some of the kids are watching a video on TV of Music/CyndiLauper singing "The Goonies R Good Enough", meaning the song exists in the movie's universe. Although they are not seen (as what's shown on TV is not actually one of the music videos), the kids and producer Creator/StevenSpielberg are shown as characters in the music videos for this song.
* Subverted in ''{{Film/Birdman}}''. Early on, mention is made of the Franchise/MarvelCinematicUniverse, but not the Hulk, who was briefly played by Creator/EdwardNorton (who plays Mike Shiner in this film). But it gets complicated as Creator/MichaelKeaton appears as the Vulture in ''Film/SpiderManHomecoming''. In addition, the fictional ''Birdman'' franchise seems to take the place of the 90s version of ''{{Film/Batman}}'', the first two of which starred Creator/MichaelKeaton (Riggan Thomson), and served as the first wildly popular and successful superhero films.
* ''Film/CaptainAmericaTheWinterSoldier'' has a [[FreezeFrameBonus notebook where Cap is writing pop culture works to catch up on.]] One is ''Franchise/StarWars'', which as ''WebVideo/HonestTrailers'' pointed out, could confuse him once he's seen the prequels given [[Creator/SamuelLJackson Mace Windu has some resemblance to Nick Fury.]] The prequel trilogy also features Natalie Portman (Jane Foster from the ''Thor'' movies) as Padme Amidala. The UK version also includes the BBC series ''{{Series/Sherlock}}'', whose star Creator/BenedictCumberbatch would join the MCU as [[Film/DoctorStrange Doctor Strange]], and whose costar Creator/MartinFreeman would appear in ''Film/CaptainAmericaCivilWar''.
* In ''Film/TheAvengers2012'', Tony's reputation as a nicknamer leads him to tell Hawkeye, "Better clench up, [[Literature/TheLordOfTheRings Legolas]]" at one point. But Creator/MartinFreeman (Bilbo in ''The Hobbit'' films) appears in ''Film/CaptainAmericaCivilWar'' as Everett Ross, Creator/BenedictCumberbatch (Smaug) plays Doctor Strange, and Creator/DavidWenham (Faramir) appears in ''Series/IronFist2017'' as Harold Meachum.
* One of the most surreal aspects of ''{{Film/Chappie}}'' is the way the members of South African rap group DieAntwoord, Ninja and Yo-landi Visser, play a pair of South African gangsters named Ninja and Yo-landi, who listen to the music of DieAntwoord. At the end of the film, Ninja is seen wearing a DieAntwoord shirt which names Yo-landi Visser as a member [[spoiler:which is oddly poignant, considering this is after her character has died]].
* In the Music/ElvisPresley movie ''G.I. Blues'', Elvis' character is singing with a band in a bar when a guy goes to the jukebox, saying "I want to hear an original," and plays [[CoveredUp Elvis' version of]] "Blue Suede Shoes".
* In Creator/JeanLucGodard's ''A Woman Is a Woman'' this trope is [[InvokedTrope Invoked]] and PlayedForLaughs twice. Jean-Paul Belmondo's character excuses his late arrival by claiming he was watching ''Film/{{Breathless}}''. Later, he asks a character played by Jeanne Moreau how's it going with ''Film/JulesAndJim'', which deliciously [[LampshadeHanging has a comparable plot]]. Moreau then looks [[BreakingTheFourthWall directly]] into the camera, [[TrollingCreator grinning]].
* In the ''Film/{{Hitman}}'' film, during 47's escape from the hotel, he bursts into a room where two guys are playing one of the ''VideoGame/{{Hitman}}'' games.
* The Australian musical ''Starstruck'', which had sets designed by Brian Thomson, shows teenage protagonist Jackie standing in her bedroom next to a pop art mural that prominently features the ''Film/TheRockyHorrorPictureShow'' RKO/swimming pool set, designed several years earlier and an ocean away by Brian Thomson. Another RHPS connection; ''Starstruck'' screenwriter Stephen [=MacLean=] has said that he wrote the film intending for his pal, RHPS's Little Nell, to play the lead -- however, by the time the film was greenlit, she was a few years too old to pass for 18.
* In ''Film/DinnerAtEight'' one of the people going to the dinner grouses that he'd rather go see the new Creator/GretaGarbo movie. One wonders if that's ''Film/GrandHotel'' -- and if so, how some of the characters from ''Dinner at Eight'' (Oliver Jordan, Larry Renault, Dan Packard) feel about having movie actors (Creator/LionelBarrymore, John Barrymore, Wallace Beery) who look just like them.
* ''Film/XMenFilmSeries'':
** ''Film/{{Deadpool|2016}}'': Played for meta-laughs since the eponymous character (who is portrayed by Creator/RyanReynolds) [[MediumAwareness is fully aware that he's in a movie and played by Ryan Reynolds]].
** ''Film/XMenApocalypse'': ''Film/ReturnOfTheJedi'' is featured in the film. Three actors in the film franchise have appeared on a ''Franchise/StarWars'' film; Ray Park in its prequel, ''Film/ThePhantomMenace'', Creator/RoseByrne in its second prequel, ''Film/AttackOfTheClones'', and Creator/OscarIsaac in its chronological sequel, ''Film/TheForceAwakens''.
* CentralTheme: The main threads throughout the story are families coming together, and that love is stronger and more powerful than fear, hate or anger.
* In ''Film/NearDark'', directed by Creator/KathrynBigelow, the protagonist is seen passing in front of a movie theater screening Creator/JamesCameron's {{Film/Aliens}}. There was a point where Bigelow and Cameron were married in real life, making you wonder who married James Cameron in ''Near Dark'''s universe.
* ''Film/{{Smarty}}'': In one of several discussions about how it's okay for men to smack women around, Tony mentions that he saw a movie where a man shoved a grapefruit in a woman's face, and it was no big deal. That's a reference to ''Film/ThePublicEnemy'', which co-starred Joan Blondell (Mae Clarke took the grapefruit to the face).
* In ''Film/ThePlayer'', a dark satire of the film industry, a notable number of recognizable actors [[CelebrityCameo appear in the film]] [[AsHimself as themselves]]. Notably at the end (delivering the punch line to the movie's main BrickJoke) are Creator/BruceWillis and Creator/JuliaRoberts. No mention is made of the film's principal actors, notably Tim Robbins (who would later co-star with Julia Roberts in ''Film/PretAPorter''), Creator/WhoopiGoldberg (who had co-starred with Bruce Willis in an episode of ''Series/{{Moonlighting}}'') and Lyle Lovett (who for awhile was married to Julia Roberts in real life). Also making a cameo in this movie is Creator/SusanSarandon, with whom Tim Robbins was romantically involved at the time.
* In the flashback sequences of ''Film/ManOfSteel'', Clark is shown as a kid, running around with a cape and standing in the classical Franchise/{{Superman}} "hand on hips" pose. How did he know to do that, if ''he'' is supposed to grow up to become Superman?
* In ''Film/MrAndMrsSmith'', the Tank has a ''Film/FightClub'' t-shirt. John Smith is played by Creator/BradPitt, who was Tyler Durden in ''Fight Club''.
* One [[https://www.youtube.com/watch?v=SyEcjLFZ0Q8 viral video]] for {{Film/Independence Day Resurgence}} plays with this trope. In it, Creator/JeffGoldblum and David Levinson are put face-to-face, to prove once and for all that they’re not the same person.
* ''Film/ReadyPlayerOne'' is directed by Creator/StevenSpielberg; to avoid seeming too egotistical, he [[http://www.cinemablend.com/news/1525840/one-steven-spielberg-reference-thats-definitely-going-to-be-in-ready-player-one cut out several references to his own movies from]] the [[Literature/ReadyPlayerOne book]], though others are left in.
* ''Film/LazerTeam'', being made by Creator/RoosterTeeth, has background characters dressed up in Machinima/RedVsBlue and WebAnimation/{{RWBY}} cosplay, RWBY stickers on Mindy's laptop, and the fact that two of the main characters are played by Team [[Creator/GavinFree Nice]] [[Creator/MichaelJones Dynamite]].
* The plot of [[Film/SiebenZwerge 7 Zwerge - Der Wald ist nicht genug]] centers around [[TwiceToldTale the seven dwarves searching for Rumplestilskin's name in order to save Snow White's baby]]. On their journey, they travel to the real world and end up in a fairy tale theme park, where they are mistaken for actors and encounter someone playing Rumplestilskin, doing his famous dance (which naturally gets interrupted before he says his name).
