Bradley Cooper‘s big film Limitless hits theaters this weekend and also stars Robert DeNiro. Bradley told David Letterman last night on The Late Show With David Letterman that he has a problem impersonating people after working with them.
“Is he the kind of guy when you work with you kind of start talking a little like him?” David asked Bradley of working with Robert.
“Oh God. Well, I have that problem anyways. I got like four movies just pretending I was Vince Vaughn after Wedding Crashers.”
“But I’ve worked with some characters,” he added. “I mean Owen Wilson…”
He then impersonated Owen and says he started impersonating Robert without even knowing it.
“I was so freaked out about it that I warned Todd Philips when we were shooting Hangover Part 2. I said, ‘Hey, look. I think I might start acting like DeNiro so catch me.’ “
“And during one scene, I’m not kidding, he goes, ‘Hey Bradley, come here come here come here.’ We’re watching playback. ‘You’re doing DeNiro!’ “
