Rosemary's Baby

In this fastidious, frightening adaptation of Ira Levin's novel, young housewife Farrow moves into a new apartment block where she comes to believe that her neighbours are witches and her husband is the Devil.

Polanski works at the ambiguity factor all the way through by contrasting the everyday surroundings with the extraordinary events (imagined or otherwise) taking place in and around them, while the cast all play it with some conviction.
