Months ago, Michael Keaton was walking around in his underwear right outside my window and I missed it. It was all for his bizarre new movie, Birdman. Where he plays an actor who has fallen out of the public favor after reaching global success in a superhero film. This international trailer gives a better look at the stress of being a “has-been” and how that can unravel someone whose creative endeavors are tied so tightly to public opinion and ego. Also, there’s a giant bird fighting helicopters and Naomi Watts making out with another lady.
