The previous trailers for the dark comedy Birdman have been a bit quirky and funny. This newest one is a full on mindtrip. Michael Keaton plays an actor who is famous for being Birdman, so basically it's a mirror to Keaton's real life connection to Batman only way more twisted and weird. Keaton's character is experiencing a mental breakdown and hearing Birdman in his head. He's also lost touch with reality to the point of delusions and hallucinations.
Birdman takes flight October 17th (USA).
