Director Milos Forman‘s pitch-black comedy in which the crazies take over the madhouse is an anti-authoritarian classic, an angry yet often playful insurrection against “the system” led with charm and charisma by Jack Nicholson‘s Randle Patrick McMurphy and countered with cruelty and cunning by Louise Fletcher‘s Nurse Ratched. Alternately hilarious and harrowing, One Flew Over the Cuckoo’s Nest may inspire you to start a revolution of your own — or at least take the day off to go fishing. While it’s definitely Nicholson and Fletcher’s ball game, Brad Dourif is the pinch hitter with his heartbreaking performance as the stuttering Billy Bibbit. The film took home all five major Oscars (Picture, Actor, Actress, Director and Adapted Screenplay) in 1976, an accomplishment that hadn’t happened since 1934 with It Happened One Night and wouldn’t happen again until 1992 with The Silence of the Lambs.
