Rosemary's Baby (1968)
Directed by Roman Polanski

WILLIAM FRIEDKIN SAYS: ''I think it's the nightmare of many women that they're gonna give birth to a child that is evil. Not only evil, but the progeny of the devil. The young husband, played by John Cassavetes, makes a pact with a group of demon worshippers to allow the devil to have sex with his wife for the purpose of bringing onto Earth the child of Satan. And what is perhaps the most terrifying sequence of all, the mother, played by Mia Farrow, sees this baby, which is clearly a demon, and like all mothers, she embraces it. Really, it's about blind ambition, and how far this young couple will go to achieve success. It deals with the demon inside all of us.''
