mr. de niro? my name is bradley cooper. my question is regarding "awakenings." >> kroft: but bradley cooper was never a struggling young actor. he was making out with carrie bradshawll in grad school. a year later, he had a tv series, "alias," alongside jennifer garner. and promptly paid off that college loan. but he was not an overnight sensation, either. you may remember him as the obnoxious fiance who made a big hit in "the wedding crashers." >> boo-yahh! >> big tree fall hard, right? >> how many fingers i got up? c'mon pepe, how many fingers i got up? come on, you know i drive great when i'm drunk. >> kroft: but it took him four more years and a road trip to vegas for a bachelor party to make him a movie star. "the hangover" grossed nearly a half-billion dollars world wide. >> we lost doug. >> we're getting married in five hours. >> yeah. that's not going to happen. >> kroft: really, things started to change, i guess, with "the hangover." i mean, that was huge. >> cooper: massive, oh, yeah. yeah, yeah, any time you're part of a movie that makes that much money in the box office, it's going to provide opportunities for other studios to take chances with you, ju
