!The Cartoon Series
* AdaptationDisplacement[=/=]WeirdAlEffect: For some ''WesternAnimation/HarveyBirdmanAttorneyAtLaw'' may have been your first introduction to the character, presuming you weren't alive for the 1960s or if you had never seen any of the 1990s reruns.
* MemeticMutation: The distinctive way the title character shouts "Biiiiiiiiird-man!" at the end of the opening credits.

!The Film
* AlternateCharacterInterpretation:
** Riggan's Birdman persona. Is he a malevolent presence that wants to torment Riggan? Or a gruff voice of reason meant to help Riggan by telling him the truth and boosting his ego? Or is he somewhere in between? A figure providing a mental crutch that simultaneously traps Riggan in his nostalgia and helps him get through the stress of his TroubledProduction?
** There are a lot of viewers who think Mike was actually attempting to rape Leslie on the stage in the bed due to her reaction, and those who think he was simply [[EnforcedMethodActing faking her out to give her that reaction]].
* AwardSnub: Although the film was nominated for nine, tying ''Film/TheGrandBudapestHotel'' for the most nominations, it received no nomination for Film Editing, which is strange considering how it's one of the most distinctive aspects of the film's style. Some also felt that Michael Keaton should've won for Best Actor at the Oscars over Eddie Redmayne for ''Film/TheTheoryOfEverything''.
* BigLippedAlligatorMoment:
** [[spoiler:Lesley and Laura]]'s [[GirlOnGirlIsHot lesbian kiss]] scene, which doesn't have any impact on the plot and is never mentioned again afterwards, and [[spoiler:Laura]] doesn't even get called out for [[spoiler:cheating on Riggan]].
** There's also a quick background shot of two naked people walking around backstage, who may or may not be the above mentioned.
* EasilyForgiven: Mike [[AttemptedRape attempts to rape]] Lesley during a preview in clear view of the cast, crew, and audience. Only Lesley and Sam call him out and all is forgiven by the next day.
* GeniusBonus: Of course, ''[[Creator/JorgeLuisBorges Borge's]] Labyrinths'' is the book Mike is reading while in the tanning booth. It's blatantly symbolic of him, Riggan, and the film's high art obsession along with the film's MagicalRealism elements.
* HeReallyCanAct: Despite losing the Oscar for Best Actor to Creator/EddieRedmayne, there's no denying that Michael Keaton delivers a stunning performance after over a decade of mediocre and secondary roles.
* HilariousInHindsight:
** After this film reflecting Innaritu's real life distaste for superhero movies with a special focus on the Franchise/MarvelCinematicUniverse, the actor playing the show's costumer went on to a prominent role in ''Series/JessicaJones''.
** So much regarding Creator/MichaelKeaton, which makes the metatextual aspects of the movie all the more relevant.
*** The story is about a former superhero actor, who has fallen out of the public eye for a while, trying to reinvent himself as a prestige actor. This movie marked the beginning of a CareerResurrection for Keaton.
*** On the subject of the Franchise/MarvelCinematicUniverse (which this movie [[TakeThat alludes to in a pretty disparaging way]]), Michael Keaton being courted for a role in ''Film/SpiderManHomecoming'' makes his character's reluctance to return to superhero movies that much more ironic.
*** Keaton being confirmed to play Vulture in that very movie is a pretty obvious ActorAllusion to ''this'' movie, making the concept of the Birdman persona in its relation to promoting Riggan's CareerResurrection amusing. That in-movie, it says that they need to go back to doing another ''Birdman'' movie now that Riggan is in the limelight again, makes Keaton's decision to play Vulture outright hysterical.
*** Finally, Keaton's casting in a ''Franchise/SpiderMan'' movie puts his estranged relationship with his daughter--whose actress, Creator/EmmaStone, played Gwen Stacy in the now-defunct ''Film/TheAmazingSpiderManSeries''--in an amusing new light, considering that both thespians are now separated by different incarnations of ''Spider-Man'' adaptations.
* HypeBacklash: Following its Oscar win for Best Picture, there was a slew of criticism that the movie's victory was more politically motivated due to its numerous {{Take That}}s at the Superhero genre and the director's own quite negative remarks about the genre.
* SciFiGhetto: While the film stands as an aversion considering it was a best picture winner, arguably some of it is believed to come from [[http://comicsalliance.com/birdman-director-says-superhero-movies-are-cultural-genocide/ Iñárritu's own distaste for superhero films]] bleeding over to the film.
* SignatureScene: The scene where Riggan walks through Times Square in nothing but his underwear.
* TrueArtIsAngsty: The movie depicts how the world of Broadway is embracing this trope. Riggan's suicide attempt is the icing on the cake.
