Terrifying and darkly comic, Rosemary’s Baby marked the Hollywood debut of Roman Polanski. 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 Blackmerand an Oscar-winning Ruth Gordon, and self-involved husband are hatching a satanic plot against her and her baby. In the decades of occult cinema Polanski’s ungodly masterpiece has spawned, it’s never been outdone for sheer psychological terror.
