Na na na na na na na na, Bird-man!
Birdman? Wait, WHAT??
Michael Keaton, a.k.a. the dude who spent the ’90s playing Batman in two AH-Mazing Tim Burton movies, stars as a washed-up actor who was once an iconic superhero in Birdman (or The Unexpected Virtue of Ignorance)!
Ha! We see what writer/director Alejandro Gonzalez Inarritu did there!
Ch-ch-check out the outrageous and totally self-reflexive teaser trailer for yourself (above)!
Whoa! Keaton strips down to his tighty-whiteys, dodges fireballs, AND beats the crap out of Ed Norton?!!? This looks in-SANE!
Birdman, also starring Emma Stone and Zach Galifianakis, swoops into theaters October 17th!
