Brad Pitt fights zombies in "World War Z" trailer

Brad Pitt is off to save the world in "World War Z," and the first full trailer for the film has now arrived.

Paramount released the two-and-a-half-minute clip Thursday. The film, based on Max Brooks' bestseller "World War Z: An Oral History of the Zombie War," stars Pitt as a UN researcher trying to save his family (and the world) from a zombie pandemic.

Mireille Enos ("The Killing") plays Pitt's wife. In the trailer, he is shown leaving her and their children to help fight against the zombie hoards, but vows that he will come back to them.

The film, which reportedly cost $180 million to make, was originally set for a December release. After undergoing script revisions and reshoots, it's now scheduled to hit theaters in June.
