And thus a whole new era was born, with more blood and gore: Alfred Hitchcock's Psycho (1960), the gore factor raised to a maximum by Herschell Gordon Lewis' Blood Feast (1963), Roman Polanski's Rosemary's Baby (1968), George A. Romero's Night of the Living Dead (1968), William Friedkin's The Exorcist (1973), David Cronenberg's Shivers (1975), Brian De Palma's Carrie (1976), and culminating with John Carpenter's Halloween (1978).
