It's Brad vs. Zombies in 'World War Z'

Zombie attack!!! Brad Pitt plays a family man and United Nations employee who faces a deadly zombie pandemic in World War Z -- we gave you an exclusive first look and now we've got the intense trailer!
Just when you thought that the zombie genre may be starting to generate less screams and more Zzzz's, World War Z arrives with an adrenaline shot in the arm for the genre -- complete with insane special effects and a claustrophobic urgency and realism not seen since the introduction of those "speed zombies" in 28 Days Later.
Directed by Marc Forster (Quantum of Solace), World War Z invades theaters June 21, 2013.
