Pitt: 'World War Z' Hoopla Is 'Pretty Damn Cool'

Though Brad Pitt is one of the biggest movie stars in the world, it's nice to know that he's still able to get excited about things -- namely his blockbuster film World War Z's huge New York City premiere in Times Square Monday night.

"We're going big -- we're going big on this, we're not messing around," Pitt says about taking over Times Square. "It's not your usual affair is it? It's pretty damn cool, I gotta say. Pretty damn cool."

Pitt also tells ET that either Angelina Jolie or their kids are always with him as he promotes the film all over the world. And thankfully his son Maddox, 11, who he credits with starting the zombie craze in his household, approves of the epic summer film.

"He's been aware of it [all the work put into making World War Z]. But he gave it a thumbs up, so it was worth it."
