Flush with success at the box office, Paramount has announced it's working on a sequel to the Brad Pitt-vs.-zombies blockbuster World War Z. The project was originally intended as a trilogy, was then scaled back to a single movie whose production was nearly scrapped after a troubled shoot, only to see the movie bounce back to become an unexpected hit—so pretty much anything could happen at this point. Still, the film's $66 million opening weekend was enough to convince the studio that perhaps people will go to see a movie with Brad Pitt in it after all.
