Paramount faced a long, difficult road to adapt Max Brooks' book World War Z: An Oral History of the Zombie War.  It will be hard for a quality film to emerge from the endless rewrites and extensive reshoots (not to mention crazy run-ins with the law), but when Brad Pitt stars is in a zombie action movie, you have our attention.  The trailer for World War Z premieres on Thursday, and ET released a sneak preview of the footage.  The quick clip gets across the message that World War Z is B-I-G.  There are hordes---heck, literal piles at points---of zombies that attack in such great mass that they seem to overwhelm even our most powerful military weaponry.  If nothing else, I think we can all get behind a film that shows us large-scale zombie carnage on some level.Anthony Mackie, Matthew Fox, Mireille Enos, and James Badge Dale co-star in the adaptation directed by Marc Forster (Quantum of Solace).  World War Z opens on June 21, 2013.  Watch the trailer preview after the jump.
