'World War Z' director Marc Forster discusses re-shoots on Brad Pitt zombie film
There are some minor spoilers below, but most of what we saw consisted primarily of action scenes, with little dialogue or plot development (and we saw nothing of the film's ending, of course).
Another narrow escape finds Pitt and his wounded military escort on a crowded commercial plane, where -- the trailer indicates -- even more hell breaks loose.
As Forster explained, the film's zombies aren't super-powered, they're just driven by pure, animal instinct; they don't know when a roof is ending and that the ground is going to fall out from under them. Likewise, they don't see windows, doors or walls as impediments, they just keep trying to run and push through them in order to feed. They're like cannibalistic parkour enthusiasts all jacked up on PCP. And that means shots of them head butting their way through windshields in order to chomp on car-bound victims.
In this way, "WWZ" is less about surviving a widespread epidemic or hiding from terrifying creatures that used to be your friends and family, and more about dealing with a seemingly unstoppable force of nature, the kind more typically seen in a disaster movie.
"WWZ" appears to be very loosely adapted from Brooks' book, and may have sacrificed the highly-detailed, reflective -- and often overtly political -- nature of the book's fictitious interviews in favor of balls-to-the-wall action set pieces.
