The Incredible 2-Headed Transplant

Dr. Roger Girard (Bruce Dern) is a rich scientist experimenting with head transplantation. His caretaker has a son named Danny (John Bloom) who is an extremely strong full-grown man, but he has the mind of a child due to brain damage sustained in a mine accident. In an unusual turn of events, Manuel Cass (Albert Cole), a recently escaped mental patient and serial killer, has murdered Dr. Girard's caretaker and is seriously injured himself. Given an unprecedented chance to use human subjects – a mortally wounded psychotic and a disabled man with little chance of surviving on his own, neither of whom he thinks will be missed – Dr. Girard transplants Cass's head onto Danny's body to prove that his techniques can be applied to human beings. The new creature, with one head of a murderer and the other with the mental capacity of an eight-year-old attached to an extremely powerful body, escapes and wreaks havoc.[3]

The film was shot in six days in Santa Monica, California. Lead actor Bruce Dern claimed he never got paid for his services.[5]

Variety called the film "rank exploitation fodder" directed "lifelessly," though it called the makeup and design of the two-headed creature "good."[6] Gene Siskel of the Chicago Tribune gave the film 1 star out 4, writing that if the film "had focused more on the conflict of the two heads with, say, some extended conversations in close-up, it could have been one of the great bad movies. Instead, we get repetitive shots of the killer drooling while the giant whines 'no, no.'"[7] Kevin Thomas of the Los Angeles Times called the film "lots of fun because this AIP release has been so thoroughly worked out, with good, legitimate performances, logical plot development and taut directing and editing."[8] David McGillivray of The Monthly Film Bulletin wrote, "Uproarious nonsense, looking very much like a piece of low budget Fifties horror and performed with very little finesse, but quite watchable none the less."[9]

In 1989, horror punk band Haunted Garage recorded a song of the same title based on the film for their 7" EP Mothers Day.
