Watch: New Clip, Featurette, Pics And More From Alejandro González Iñárritu’s ‘Birdman’

"...with 'Birdman,' [Alejandro González] Iñárritu, [Michael] Keaton, and our own faith in the limitless possibilities of cinema, are reborn," our own Jessica Kiang wrote out of the Venice Film Festival. Frankly, if you need more convincing to see "Birdman," we're not sure what to tell you, so we'll leave it to this promo material. Keaton leads an ensemble including Edward Norton, Emma Stone, Zach Galifianakis, Naomi Watts and more in the tale of an actor who had formerly played a superhero in a blockbuster film who then tries to revitalize his career on the Broadway stage. It's a challenge, and as you'll see in the new clip below, even the theater world needs a bankable name to sell tickets. After that, a new feature goes up another level, and that's followed by a couple of TV spots and some new pics via IMDB. "Birdman" opens on October 17th.
