"World War Z" hasn't even premiered in the U.S. yet, but that isn't stopping star Brad Pitt from predicting possible sequels to the zombie flick. Asked about the viability of potential follow-ups at the Moscow International Film Festival, Pitt was optimistic that future films -- also based on the Max Brooks book -- could work.
"There is enough [material] to mine from the book," he said. "We could barely get a fraction of the book in [this movie]. So we'll see. We'll see."
Pitt, who plays United Nations employee Gerry Lane in the film, didn't specify whether or not he would return for sequels, though The Hollywood Reporter says that "Z"'s ending has Pitt's character sizing up the war against zombies as just getting started.
Despite Pitt's optimism about the movie's franchise potential, director Marc Forster is keeping a lid on any sequel talk until he can gauge the success of the original.
"Let's see how this goes," Forster said. "We hope this movie goes well and we shall go from there."
"World War Z" opens nationwide Friday.
