Denzel Washington plays Eli in The Book of Eli, a movie that takes place in post-apocalyptic America. The country is a wasteland of ruins and everyone wants the one thing Eli won't give up: the book that holds the only hope of mankind's redemption. Denzel knows how to play a grizzled badass, and the action and effects look pretty great. Oh -- and Mila Kunis is in this. Need any more reasons to check out the trailer? See it after the jump.
