World War Z certainly had a bumpy production trip to the big screen. The movie got pushed back six months, had a troubled shoot, and an ending which needed assistance from man who isn’t exactly well-regarded for his endings. Based on this first trailer for the film, some of the more creative troubles are on display. Word was Marc Forster was unsure of what type of zombies he wanted, and the kind he went with go against the gritty, grounded style he’s clearly aiming for. Whenever a horde of CG zombies appear in this trailer, Forster’s “serious” approach falls flat. Nothing can take someone out of a movie more than an all-CG character, but there looks to be plenty of cartoon zombies running amok in World War Z.
