Edited to look like it was shot in one continuous take, the film "Birdman" stars Michael Keaton as an actor once famous for playing an iconic superhero in big-budget films. In an attempt to find relevance and meaning in his life, he mounts a Broadway play based on a Raymond Carver short story. The cast includes Emma Stone, Edward Norton, Zach Galifianakis and Naomi Watts. Alejandro González Iñárritu directs.
