Holy Crap! Denzel Washington in a movie where he doesn't play Denzel Washington? I've waited for this day for so very long.
Book of Eli is about a man in a post-apocalyptic wasteland that may or may not have some kind of key to the future of humanity and life on Earth. It's all Fallout-like and awesome, with crazy vistas of destruction and the remaining humans are all trying to kill each other. And there's Gary Oldman, who can resist some Gary Oldman? No one, that's who.
It's like watching Fallout and Canticle for Leibowitz (a great book, go buy and read it) played out on the big screen, with explosions and awesome! Man...I can't wait to see it!
