It's been decades since Michael Keaton was Batman, but it's still impossible not to associate him with the role. Now, Keaton is taking those associations and fictionalizing them in Birdman, where he stars as a washed up actor who used to be synonymous with the flying superhero. The film comes from director Alejandro González Iñárritu, who's made his mark through ensemble films with intertwining stories, like Babel. A new trailer for Birdman was just released, and it revels in the dark, funny, and surreal. The movie looks incredible (though we've known that since the first trailer), and it'll be in theaters later this year on October 17th.
