‘World War Z’ Clip: Brad Pitt Makes a Daring Rooftop Escape

'World War Z' hits theaters this weekend, and Paramount wants to make sure you're good and pumped for it. The studio has released a brand new extended clip from the film, featuring Brad Pitt's Gerry Lane making a daring rooftop escape with his family in tow, including 'The Killing' star Mireille Enos.

It's the same scene teased in previous trailers for the film, but here we get an extended look at the rooftop chaos -- which isn't that chaotic -- and a glimpse at a couple of zombies. It all happens a bit fast though, and the focus is mostly on Gerry and his wife and kids as they make a mad dash for the helicopter.

'World War Z' has had some troubled history, with director Marc Forster ('Quantum of Solace,' 'Stranger Than Fiction') notoriously going back for re-shoots on the costly production. Recently, Pitt visited a handful of special advance screenings to help promote enthusiasm for the film, which hits theaters this Friday, June 21.

And if you're really excited, Paramount has released special $50 tickets in select cities, which will allow fans to see the film two days early. In addition, buyers will receive a special pair of 3D glasses, digital content, a limited edition movie poster, and popcorn (of course).
