“I got 99 problems and a zombie definitely is one!” – It was a film dogged by setbacks and problems, but now the trailer to the much loved book “World War Z: An Oral History of the Zombie War” is out and it seems to center around Brad Pitt and his family — and Brad Pitt needs to save the world but that looks dubious because there’s shit loads of raging zombies who can scale walls in seconds. This looks awesome.
