What would happen if Zombies really started taking over? Well,... who knows. But it makes for a cool movie with Brad Pitt and millions of co-star extras. Boom. Done.
Can you imagine how many outfits they had to destroy for this movie? Oh, wait... they're CG. Never mind... just check out the trailer 'cause it's fun. Something to take the wee kids to see for their birthday. ;-)
