!The Cartoon Series
* AdaptationDisplacement[=/=]WeirdAlEffect:
** Admit it. You came to this page from something related to ''WesternAnimation/HarveyBirdmanAttorneyAtLaw''.
** That or Music/WesleyWillis' song "Birdman Kicked My Ass".
** Or the 2014 movie starring Creator/MichaelKeaton.
* 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 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.
* CriticalDissonance: In fact, as of its win at the 2015 Oscars, ''Birdman'' was the 2nd lowest-grossing Best Picture winner of all time. The only one that grossed less was ''Film/TheHurtLocker''. (Don't let the "lowest" statistic bother you though - despite that the film has made five times its budget in profit, so it was absolutely a success as a film.)
* 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.
* 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.
