The Incredible Two-Headed Transplant is a 1971 American horror film directed by Anthony M. Lanza and starring Bruce Dern, Patricia Ann Priest, Casey Kasem, and Albert Cole. The film tells the story of Dr. Roger Girard (Dern), a scientist experimenting with head transplanting who makes a fatal error when he tries to save a life. Danny (John Bloom), the caretaker of his estate, has a son who, although is the age of an adult, acts like a child. When an escaped rapist breaks into Girard's home and kills Danny's father, Danny's son is deeply unsettled by everything that happens. With the rapist near death himself, Girard transplants the killer's head onto Danny's body. Girard has now created a two-headed monster that terrorizes the town and goes on a killing rampage. When the film was released it was distributed on a bill as a double feature with Scream and Scream Again, starring Vincent Price and Christopher Lee.
