5 Most Memorable Jack Nicholson Performances 2010 One Flew Over the Cuckoos Nest
One Flew Over the Cuckoo's Nest (1975): The quintessential Nicholson role: He's charmingly subversive, a little volatile, perhaps a little dangerous, but usually smarter than everyone else in the room and always fascinating to watch. Nicholson won his first Academy Award for best actor -- he'd win another for "As Good As It Gets" and a supporting-actor award for "Terms of Endearment" -- for his role as the mental institution rebel R.P. McMurphy. Of course he's not really crazy, but the relationships he forges with his fellow patients reveal another side of Nicholson's persona: the loyal man's-man.
