“[Birdman is] a black comedy that tells the story of an actor (Keaton) – famous for portraying an iconic superhero – as he struggles to mount a Broadway play. In the days leading up to opening night, he battles his ego and attempts to recover his family, his career, and himself.”
Also appearing in the film is Edward Norton, who, according to Deadline, was cast as an “egotistical lead stage actor” who disrupts Keaton’s attempts to create the Broadway play that will rejuvenate his career. Norton has something of a reputation for being difficult to work with – so much so that Kevin Feige more or less explicitly stated this as the reason for dumping him in favor of Mark Ruffalo when casting Hulk in The Avengers. It will be interesting to see whether Norton is willing to indulge in a little self-parody for his role in Birdman.
