Shortly after World War Z took in an impressive $66 million at the box office this June, Paramount Pictures announced a sequel was moving forward. At the time, it wasn't known if Marc Forster would be coming back to direct. Today we have word that the director is not returning for the zombie sequel, although it is still moving forward and is in development.

Here's what star/producer Brad Pitt had to say about the follow-up.

"We are talking about it. We are going to investigate a script. We have a lot of ideas we will cull from. Nobody is writing just yet, but we are compiling our ideas."

The original World War Z, which went on to gross $539 million worldwide from an estimated budget of $190 million, had several writers credited, including Matthew Michael Carnahan, J. Michael Straczynski, Drew Goddard and Damon Lindelof. It isn't known if the studio plans on bringing one of these writers back for the sequel, or if Brad Pitt's Plan B Productions and Paramount are seeking a new writer.

Brad Pitt portrayed former U.N. employee Gerry Lane in World War Z, who travels around the world in hopes of finding a cure for the zombie virus that is rapidly spreading across the globe.
