Carnival Night revolves around the planning of a New Year's Eve party and variety show in 1950s Moscow.
The Last Command: Sergius, a former general of Russian Empire, is now an extra in a movie about the Revolution.
Souls for Sale is a rather unique instance of this trope. The heroine is an actress who gets a big part in a movie about a circus. However, additionally to this, the heroine visits the sets of several real films that were in production at the same time Souls for Sale was. Among the sets she visits are A Woman of Paris (where she's an extra directed by Charlie Chaplin himself) and Greed (where she fails to get a part in Erich von Stroheim's production).
The plot of The Callback Queen (2013) is set in London's film industry and hinges on a film adapatation of a fictional fantasy novel, 'Prince of Chaos', with which the characters are involved.
Matinee (1993) which counts in all four categories due to being structured around the premiere of the atomic monster movie MANT! in Key West — during the Cuban Missile Crisis!
The film version of Rosencrantz and Guildenstern Are Dead has the players acting out Hamlet for the title characters, while acting out The Murder of Gonzago with puppets who are themselves acting out the play-within-a-play with finger puppets. A show within a show within a show within a show.
Stormy Weather: Since this movie is about a dancer and a singer, there are various shows that they are involved in.
During ¡Three Amigos!, characters watch one of the title character actors' silent films.
Moulin Rouge! is a musical movie depicting a stage performance of a movie about a man singing about a man writing the story of his involvement in a musical about a man whose involvement in a musical mirrors the writer's. Honestly.
In the 1998 film Lucia, the protagonists simultaneously prepare to perform the opera, Lucia di Lammermoor, while reliving the roles of their characters.
The film version of Bewitched is about a remake of the original TV series and the people in it — one of whom is an actual witch.
The fictional Galaxy Quest TV show in the real movie Galaxy Quest. The film centers on the washed up cast members of the show.
Done in Ararat, a movie about someone making a movie about the Armenian genocide. Most critics and viewers agreed that it represents a rare case of the "movie within a movie" actually being better than the rest of the movie.
In Finding Neverland, the main character and several secondary characters are working on Finding Neverland.
V for Vendetta has both Lewis Prothero's and Gordon Deitrich's shows, the former being the Voice of London, a part of the facist regime controlling the city, and the latter being a comedy Sketch Show.
Porn movie Fly Girls is about the guerilla shooting of a porn film on a plane. The actors and actresses all play parodies of themselves. It's actually really funny.
The Adventures of Baron Munchausen begins with a play about the eponymous Baron, performing his tall tales in a burned out city; when the real Baron von Munchausen shows up to "correct" their portayal of him and his erstwhile companions, to whom the actors bear a striking resemblance.
The Tall Guy features Jeff Goldblum as a struggling actor who quits his job as sidekick to popular, and abusive offstage, comedian Ron Anderson (Rowan Atkinson in a hilarious self-parody). He auditions unsuccessfully for parts in several plays, and finally lands the lead role in a musical version of The Elephant Man entitled, according to his agent, "'Elephant', I think; with an exclamation point, presumably".
Inland Empire centers(?) around the production of the movie On High In Blue Tomorrows, an alleged romance that starts to mess with the main character's mind. possibly due to a curse Certain sections of the film deal with Rabbits, another project by David Lynch. As you'd expect from the man, it isn't cute. The absolutely deranged plot of both the show, the fake movie and the Film as a whole ensures you're not sure what level of reality they're on, and makes it hard to distinguish as types 1,3 or 4.
Scream 3, meanwhile, revolves around the production of Stab 3, which the masked killer manages to sabotage by killing most of the main cast. Stab 3 does still get made afterwards, but with a whole new cast and, presumably, a plot about them trying to make the failed Stab 3. It would have been a show within a show within a show, and couldn't have made much sense.
By the events of Scream 4, the Stab series has become a Franchise Zombie with seven films, having abandoned all pretense of being Based on a True Story after the third (Sidney sued to prevent any further use of the original characters) and gone into straight-out fantasy by the fifth (which included a Time Travel plot). Scream 4 begins with two characters watching Stab 7, which begins with the characters in that film watching Stab 6, just to add to the Mind Screw. Even so, the series has attained a stature on par with Friday the 13th, with Robbie and Charlie hosting a "Stab-a-Thon" party in which they screen the entire series back-to-back.
Topsy-Turvy is about the writing and production of The Mikado.
The Truman Show is about the production of a TV show about the life of a man who doesn't realise he's on TV. Whilst he doesn't know, the rest of the "cast" do.

Salome's Last Dance presents the bulk of Oscar Wilde's play Salome as a production mounted for Wilde himself by the staff of a London brothel, with the wild and woolly goings-on onstage entwining themselves with the offstage relationships between Wilde and two of the actors (one of whom is Lord Alfred Douglas — if one knows about Wilde's life they know that's not a great omen — who's playing John the Baptist in the show).
In Birdman, the protagonist attempts to stage a theatrical version of Raymond Carvers short story What We Talk About When We Talk About Love that hes adapting, directing, and starring in himself. It is not going as well as hed hoped.
Rosencrantz And Guildenstern Are Undead revolves around the production of the eponymous off-Broadway play, which is eventually revealed to actually be the life story of its writer, the real Horatio, who is in truth a master vampire who had been fighting a vampirized Hamlet over the Holy Grail for centuries, and the play, along with Hamlet, Rosencrantz and Guildenstern by W.S. Gilbert, and Rosencrantz and Guildenstern Are Dead, were all written containing secret messages designed to draw Hamlet out for a final confrontation.
The Dresser is about a Shakespearean acting troupe putting on a performance of King Lear. Thematically appropriate because "Sir", the leader of the troupe who has to play Lear, is facing similar issues regarding aging, infirmity, and death.
Howling III: The Marsupials: There are two. Donny is acting in a horror film called The Shapershifters Part 8. He wants Jerboa to join the cast, but she's never seen a horror film before, so he takes her to a B-movie called It Came from Uranus.
The Man Who Killed Don Quixote: The name of the movie comes from an old black-and-white silent student film the main character Toby directed, starring Javier, a local cobbler who starts believing that he really is Don Quixote. We see a few sequences of the student film as well as some of its production in flashback.
The incredible meta indie film Killer Flick is about four indie filmmakers creating a schlock exploitation film called Killer Flick. They reside within the film world they're creating, so we see them shooting scenes as they happen and writing plot points that come to pass.
I Am Alone: The main characters are the host Jacob Fitts, the cameraman Mason Riley, and the producer Adam Levine, of a wilderness survival show called "I Am Alone".
The ABCs of Death: The "Q" and "W" segments are about the real life crew members trying to figure out what to do for the "Q" and "W" segments for this very film.
Shortcut to Happiness opens with an extract from Jabez Stone's novel, alternating between his typing and the secene being acted out. (It's possible the title of the novel may be ''Shortcut to Happiness'', but this is never conclusively established.)
One Cut of the Dead: The first act has a film production crew making a zombie movie get attacked by actual zombies while the realism-obsessed director tries to film it all. The whole thing is shot in one continuous take. Then it turns out that this whole act was itself a film recorded and transmitted live as a television stunt. The rest of the film flashes back to show how the film was conceived and shot, revealing that many of its stranger elements were the results of improvisations due to various unexpected calamities.
Snuff Movie has Premature Burial, Boris Arkadin's classic horror film that was supposedly the inspiration for the murder of Mary Arkadin.
White Hunter Black Heart is nominally about the shooting of a film called The African Trader (a lightly fictionalized version of The African Queen) in Africa in the early 1950s. Viewers familiar with The African Queen will recognise some equivalent scenes being shot in this film.
David from The King of Marvin Gardens is the host of a late-night radio talk show called Etcetera, which seems to consist mostly of made-up stories about his past.
Eternals: There's an extended dance sequence on the set of a Bollywood movie Kingo is producing and starring in, Shandar Dastan-e-Ikaris (Legend of Ikaris). It is the third of a trilogy of movies and one of dozens of films Kingo has appeared in while pretending to be a whole family of actors.
In Idiocracy, the idiotic populace of 2505 watches Ow, My Balls, which is one Groin Attack after another. We see the unfortunate star of the show twice during the movie (other than in his show), and on both occasions, he suffers very painful "tributes" from fans who attempt to emulate the show.
Detention has the franchise Cinderhella, a SawExpy focused on a woman torturing teenagers on prom night. Ione, Clapton, Riley and Taylor are shown to like the movie, but then a killer appears murdering students using a Cinderhella mask.
The trope is then exaggerated and played for laughs halfway through the movie, when the characters are all stuck in Detention, they realize that by watching Cinderhella 3, they might be one step ahead of the killer, so they download it and watch it, the movie has the students stuck in detention having the same idea: by watching Slashing Beauty 4, they can get ahead of Cinderhella, and then again, there is a group of students stuck on detention, which also parodies Dawson Casting, who decides to watch Beauty Beast 5, who turns out to be a poorly done porno. We then have a Show within a Show within a Show within a Show.
Home Alone has the gangster movies Angels with Filthy Souls and Angels with Even Filthier Souls. (While the titles parody Angels with Dirty Faces, the scenes that Kevin watches does not.)
Amusingly, Angels with Filthy Souls was actually reused for another film, Pokémon Detective Pikachu, years later, making it a show within a show for two films in completely different universes.
In Hairspray, Tracy and Penny are huge fans of the Corny Collins Show, a regional American Bandstand-type show. Tracy gets a part on the show and supports Corny's dreams of integrating the show(instead of only permitting black performers to appear on "Negro Day").
In the film version of Matilda, Matilda's family is a huge fan of Million Dollar Sticky, a game show hosted by (or whose host is played by) Jon Lovitz, where contestants are painted with honey and then invited to roll around in money. Whatever cash sticks to them they get to keep.
The plot of the film Galaxy Quest involves certain "fans" of the show, namely a race of aliens who erroneously believe the show is real and worship the characters as heroes. Incidentally, the actions of said aliens are also what cause the film to fall under the other three types of this trope.
The film also has a couple of traditional fanboy types. They later turn out to be Chekhov's Gunmen
A major subplot in The Gamers: Hands of Fate is Gary coming to terms with the cancellation of his favorite show, Ninja Dragon Riders.
Both sequels to The Human Centipede treat the preceding movie this way. The second film's Villain Protagonist is obsessed with the first movie, to the point where he kidnaps people to make his own Human Centipede. The third film's own Villain Protagonist, a prison warden, was initially disgusted by the first two movies, but when his assistant gets an idea inspired by them, he realizes that turning the inmates of his prison into a Human Centipede as a deterrent isn't a bad idea. He even gets permission from Tom Six himself to bring the Centipede to life.
Cee from Prospect is fan of "The Streamer Girl" novel. She lost her copy of the book but had read it so many times that she was able to write the storyline into her own journal.
Show is a plot point
The movie Singin' in the Rain is all about actors learning to cope with 'talkies'. Quite possibly the first movie to ever feature a movie within a movie (1952).

Zebraman is a Japanese film that features a cancelled television series by the same name.
The very premise of the film Galaxy Quest revolves around the fictional show of the same name. The plot centers around the cast members of the eponymous show, who are abducted by a race of aliens erroneously believing the show is real and worshiping the cast members as heroes.
Nation's Pride, a pro-Nazi movie, is a plot point in Inglourious Basterds, as it serves as a draw to top Nazi officials including Hitler being in a certain movie theater in Nazi-occupied France... making them the perfect target for not one but two assassination plots.
Nation's Pride is also included as Bonus Material on the DVD, directed by Eli Roth, one of the actors in the movie.
In Finding Neverland, the production of Peter Pan ends up marking a turning point for the characters, both on opening night (for James and Peter) and as part of a later, special production (for Emma, Sylvia, and Sylvia's other sons).
German director Sönke Wortmann took this Up to Eleven with the movie he made at film school. It's about a film student who makes a movie about a film student who himself makes a movie at film school. Appropriately, it's called "Drei D" (Three D). The Movie within the movie is called "Zwei D" (Two D).
In Nurse Betty the main character witnesses a murder and experiences a fugue state, escaping into the comforting fantasy of a soap opera called "A Reason to Love". In her mind, she assumes the identity of one of the nurse characters in the daytime drama.
In Midnight Movie the main killer comes from out of the Show Within A Show.
In Enchanted, Edward and Nathaniel channel surf and briefly watch a soap opera. Some of the female lead's lines cause Nathaniel to realize the woman he's pining for doesn't care about him and is just using him.
In the horror film found., Headless is a slasher film that Steve is obsessed with and serves as a partial inspiration for his killings. In a bit of defictionalization, Headless was later made into a real film.
Goosebumps is based on the real life book series of the same name. However, in the movie, the books are fictional, despite the fact that they predated the movie, making for a rather odd variant of this trope.
The Thai horror film Coming Soon had a film-within-a-film called "Evil Spirit" as a major plot point. "Evil Spirit" is about a village woman named Shomba who gets hung after she's discovered to have been kidnapping children. Coming Soon's main character, Chen, discovers that "Evil Spirit" is a cursed film when his friend Peoll mysteriously disappears after trying to record the film in the theater.
The 1988 horror film Remote Control is about the fictional 1950s sci-fi B-movie of the same name that brainwashes everyone who watches it into becoming murderers. Interestingly, the B-movie itself features a futuristic pseudo-tape called "Remote Control" that has the same effect on people, though we don't get to see that one. And in the actual film we discover that the "Remote Control" tape itself was actually made by aliens, so the whole film is a sort of homage to the sci-fi films of old. It's all very meta.
Shredder Orpheus has Hades and Persephone run a TV broadcasting network in the Underworld, with the most popular show being Praise The Ray. The plot kicks off when Hades' goons murder Eurydice to get fresh talent for the network, and Orpheus's attempts to retrieve her are done as special programming segments in-universe.
The film Galaxy Quest is something of a literal inversion of this in that the characters find themselves in a real life situation eerily resembling the show they starred in. Though there doesn't appear to be any direct Plot Parallel.
Sherlock, Jr. (1924) stars Buster Keaton, who falls asleep and dreams while working as a theater projectionist — the movie plays a more upscale version of a real life theft he's wrongly accused of. He walks into the movie through the screen, and plays the brilliant detective he aspires to be.
The finale of Monte Carlo features a Catch the Conscience opera performance of Monsieur Beaucaire, where the events onstage parallel the heroine's life a little too closely for her comfort: just like the main character of the opera, she's a noblewoman who's fallen in love with her hairdresser.
Seven Psychopaths is a combination of this and the third category. The main character, Marty, is writing a screenplay called Seven Psychopaths. He and the other two mains spend most of the film discussing the screenplay (and in turn the film they're in), effectively deconstructing their own movie. The problems start when Marty's friend, Billy (one - in fact two - of the titular psychopaths), takes a little too much control of the plot.
Wu Luan puts on a play for the Empress's coronation in Legend of the Black Scorpion, ala Hamlet, showing a dramatized version of the murder of his father. This doesn't just get the Emperor, the tension in the room implicates that everyone knows what he's on about.
Cabin by the Lake was about a movie writer who started killing girls to get inspiration for his work. Return to Cabin by the Lake features the production of a movie based on the same killer's exploits. He commandeers the production by impersonating an Assistant Director that he murdered to get creative control over his story and starts gradually killing off the crew.
Logan involves actual real-life X-Men Comics, based on the "real" X-Men in the X-Men movie series. The comics themselves inspired a location to be built by other characters in the movie.
Ultraman Gaia: The Battle In Hyperspace detracts from the more conventional storylines featured more typically in the Ultra Series, being a Real World Episode set in our reality instead of the fictional world where Ultramen exists. Gamu Takayama, the human host of Ultraman Gaia, ends up in our world through a wish-granting alien artifact, and is surprised to learn that the show he stars in is actually made-up after seeing a toy shop selling merchandise of himself.
Zombies! Zombies! Zombies! opens with an ice skater and her coach being attacked by zombies in what looks like the start of the movie, but actually turns out to be a zombie film Jenna is watching before Chris sends her to bed.
