Rosemary's Baby
It's not what you're expecting.
This wildly entertaining nightmare, faithfully adapted from Ira Levin’s bestseller and produced by the legendary William Castle, stars a revelatory Mia Farrow as a young mother-to-be. She grows increasingly suspicious that her overfriendly elderly neighbors (played by Sidney Blackmer and an Oscar-winning Ruth Gordon) and self-involved husband (John Cassavetes) are hatching a satanic plot against her and her baby. In the decades of occult cinema that Rosemary's Baby has spawned, it has never been outdone for sheer psychological terror.
