‘One Flew Over the Cuckoo’s Nest’ (1975)

Man, the ’70s were dark — and this movie came out before Watergate. Jack Nicholson‘s anarchic character, McMurphy, ends up in a mental institution on a fluke and turns the place upside down. But the establishment has the last word. Try not to sob as Chief (Will Sampson) smothers a lobotomized McMurphy, then makes his own escape.
