The Incredible 2-Headed Transplant (1971)
Dr. Roger Girard, a wealthy scientist, delves into the controversial realm of head transplantation. His caretaker’s son, Danny, is an adult with the intellect of a child. Chaos ensues when a deranged killer breaks into Girard's residence, resulting in the death of Danny's father before the intruder is shot. Grief-stricken and disturbed, Danny is left vulnerable. Seizing the opportunity, Dr. Girard makes a radical choice: he performs a head transplant, placing the killer's head onto Danny's body, leading to unexpected and chilling consequences.
