Birdman (A. Iñárritu, 2014)

The story follows Riggan Thomson (Michael Keaton), a faded Hollywood actor best known for playing the superhero “Birdman”, as he struggles to mount a Broadway adaptation of a short story by Raymond Carver, What We Talk About When We Talk About Love. The film covers the period of previews leading to the play’s opening. With a brief exception appears as if filmed in a single shot, an idea Iñárritu had from the film’s conception.
