Horrifying and darkly comic, Rosemary’s Baby was Roman Polanski’s Hollywood debut. This wildly entertaining nightmare, faithfully adapted from Ira Levin’s best seller, stars a revelatory Mia Farrow as a young mother-to-be who 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 Polanski’s ungodly masterpiece has spawned, it has never been outdone for sheer psychological terror.
