Terrifying and darkly comic, Rosemary’s Baby marked the Hollywood debut of Roman Polanski (Repulsion). This wildly entertaining nightmare, faithfully adapted from Ira Levin’s best seller, stars a revelatory Mia Farrow (Hannah and Her Sisters) as a young mother to be who grows increasingly suspicious that her overfriendly elderly neighbors, played by Sidney Blackmer (High Society) and an Oscar winning Ruth Gordon (Harold and Maude), and self involved husband (actor and filmmaker John Cassavetes) 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.
