A new 30-second teaser trailer for Brad Pitt's upcoming zombie flick "World War Z" set to air during Sunday's Super Bowl has debuted online before the big game.

In the 30-second teaser, Pitt is seen with his character's family running from an unknown disaster. CGI-rendered zombies also pop up later on in the trailer.

"We've lost the East Coast," a voice is heard saying in the trailer. "China's dark," adds another.

A two-and-a-half-minute trailer for "World War Z" originally debuted in November.

Pitt's latest film is based on the 2006 best-selling book "World War Z: An Oral History of the Zombie War" by Max Brooks (son of Mel Brooks and Anne Bancroft), his follow-up to 2003's "The Zombie Survival Guide."

Some fans of the book have voiced their upset with the perceived action-heavy tone of the film as seen in the first two trailers released so far. Brooks' novel was written in a unique format as a collection of first-person survivor accounts from a zombie apocalypse.

"World War Z" is scheduled to arrive in theaters on June 13.
