Bradley Cooper Says Zach Galifianakis Is The 'Toughest Guy' At 'A-Team' Premiere

MTV Movie Awards nominee says not even his 'A-Team' co-stars could go toe-to-toe with bearded 'Hangover' actor.

Bradley Cooper is kicking butt and taking names as Lt. Templeton "Face" Peck in "The A-Team." But real life doesn't always imitate art, as Cooper admitted he isn't quite as tough as his onscreen Special Forces soldier. The real badass, he said, is his "The Hangover" co-star Zach Galifianakis.

"No one's tougher than Zach Galifianakis, who played Allen [in 'The Hangover'], so I don't even try to even compare anybody," Cooper told MTV News at movie's Los Angeles premiere on Thursday.

That may come as a surprise to fans looking forward to seeing the big-screen adaptation of the classic 80s TV series. "The A-Team" cast lineup — including Liam Neeson, Sharlto Copley and former UFC fighter Quinton "Rampage" Jackson — isn't exactly made up of wimpy guys.

Still, MTV Movie Awards nominee Cooper insisted bearded funnyman Galifianakis, who is nominated for Best Breakout Star at Sunday's show, was the dude to be most afraid of. "They won't make it," Cooper said of his other co-stars. "He's the toughest guy I ever met."

While Cooper was focused on Galifianakis, someone else was focused on Cooper. "The Hills" star Stephanie Pratt told MTV News she became a fan of the cute actor after seeing him in "The Hangover."

"The movie looks so funny," Pratt said. "I'm gonna say, I think I'm gonna like [Cooper] better in the 'A-Team.' "
