!The Cartoon Series
* AdaptationDisplacement[=/=]WeirdAlEffect:
** For some ''WesternAnimation/HarveyBirdmanAttorneyAtLaw'' may have been your first introduction to the character. If you weren't alive for the 60s or 90s re-runs.
* 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 9, 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.
* GeniusBonus: Of course [[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:
** The story is about an guy trying to reinvent himself as a prestige actor, which appears to be exactly what the movie accomplished for Michael Keaton.
** 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''.
** On the subject of the MCU, Michael Keaton being courted for a role in ''Film/SpiderManHomecoming'' makes his character's reluctance to return to superhero movies more ironic. Even better? The role he's being considered for is [[ActorAllusion the Vulture]]!
* 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 [[TakeThat Take Thats]] 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.
