BIRDMAN: Michael Keaton Flies Again In Groovy First Trailer

Michael Keaton sounds like he's channeling Christian Bale in the groovy first trailer for Alejandro González Iñárritu's Birdman.

That would be the 1989 Batman, speaking with a gravelly Dark Knight voice as he remembers his past glories. The trailer begins with Gnarls Barkley performing "Crazy" before a succession of wild imagery parades by, leading to an encounter between Keaton and Edward Norton that is unlike any superhero battle I've ever seen.

Birdman or The Unexpected Virtue of Ignorance is a black comedy that tells the story of an actor (Michael Keaton) - famous for portraying an iconic superhero - as he struggles to mount a Broadway play. In the days leading up to opening night, he battles his ego and attempts to recover his family, his career, and himself.

The supporting cast includes Zach Galifianakis, Andrea Riseborough, Amy Ryan, Emma Stone, and Naomi Watts. It's a welcome change of pace for the director, best known for grim tales such as 21 Grams and Babel

Watch the trailer below. The film is due in theaters this fall.
