Return of the Ape Man

In "Return of the Ape Man," Professor Dexter (Bela Lugosi) and Professor John Gilmore (John Carradine) attempt a daring brain transplant on a perfectly preserved caveman discovered during an Arctic expedition. Frank Moran stars as the Ape Man, who was frozen alive and carried by one of the explorers, including his damsel in distress, Anne (Teala Loring). The mad scientist's plan aims to implant a more evolved brain into the prehistoric man, with hopes of controlling and utilizing him.
