Brad Pitt explains why World War Z chucked the book's slow zombies

If you’ve seen any of the trailers for Brad Pitt’s oft-delayed zombie epic World War Z, one thing probably stood out pretty quickly. The zombies function more like swarming ants, as opposed to the shambling undead. So why did they make the change?

Pitt chatted with Entertainment Weekly about why they switched to what many fans have called a pretty weird style of zombie, and said the change was made to differentiate World War Z from all the other zombie movies and TV shows out there.

Here’s his explanation, via Indiewire:

“The book focused on slow zombies. We chose to be more dynamic in that we wanted to base all of this on science. So it’s ‘What if we had them move like ants? Or a swarm of bees? Or birds or a school of fish that’s being chased?’ One of the first [questions] we asked was how to portray the zombies and how to do it differently because it’s been done so many times and been done pretty damn well.”

Well, they’ve definitely pinned down a very different look when compared to other zombie movies, though the jury is still out over whether that’s actually a good thing. The trailers are intriguing, but we’ll have to wait and see if those FX can stand up for a full two-hour movie.

What do you think about the changes made to bring the book to the big screen?
