In shooting himself on stage, Riggan is lauded for his authenticity, but he is in fact just giving people the same blood, guts, and cheap thrills provided in his blockbusters. There is no difference between a lowbrow movie and highbrow theater – it's all a performance in an effort to win applause. Ultimately, both of his characters are simply costumes that obscure who he really is. The ending of the film is left purposely ambiguous: does Riggan die, and merely imagine that his daughter sees him as he sees himself, flying triumphantly over the city; or, having achieved success and made peace with his family, is Riggan's flight actually real? Innaritu posits that it doesn't matter, as this is just artificial, a show, and as such just the illusion of understanding and acceptance that is provided for the audience (the only ones that actually matter) is enough.
