We've seen a lot of Bradley Cooper lately, as he promotes 'The A-Team.' But on 'Jimmy Kimmel Live' (weeknights, 12:05AM ET on ABC), the host wanted to hear about the actor's work with Robert De Niro on 'The Dark Fields.'

"I just finished a movie, yeah, with the big man ... I call him Bob -- it's crazy," said Cooper. For one scene, Cooper told De Niro to "just really lay into me so I'll really feel it ... Say I'm a fake and all this stuff."

The camera started rolling, and De Niro obliged, churning out a lengthy, withering critique.

Cooper's reaction? He missed his cue to walk into the camera frame. "It was so real, I was just destroyed."
