Birdman is an ambitious film with great performances and excellent camera-work. The movie revolves around an actor, who famously portrayed a superhero(funnily enough, Keaton acted as Batman in the 90s), struggling to make it in the theatre world. What's fascinating about the movie is that you feel as if the movie is taken in 1 take, not kidding, 1 take. There are no cuts, no edits, as you continue to track all the actors from day to night and back to day. Editing is little rough, but the camera-work is superb and so is the performances. Keaton delivers one of his best and honest performances, and I wont be surprised if he gets an Oscar nomination. Definitely worth a look.
