is old, she finds Thomas' body young and attractive. The "solution" to this situation will be to transplant Marshall's brilliant brain into the brain-damaged Thomas's young, healthy body. To accomplish this, Tania seduces Thomas into having sex while Marshall secretly watches, and Marshall kills him with a pillow during their lovemaking. Tania then successfully transplants Marshall's brain into Thomas' body. Thomas now speaks with Marshall's voice, and his body has become inhumanly strong as well. Meanwhile, Frankenstein's monster has continued to terrorize the town, and the local villagers, having had enough, arrive with torches and pitchforks before following the monster to the castle. In the chaos, the monster returns, knocks down Harris, and has a fight with Marshall/Thomas, who cuts off his arm. When the monster bear-hugs Marshall/Thomas, Tania stabs him in the back with a sword, and Marshall/Thomas kills him by puncturing his head open with a metal hand tool. The monster is defeated, but Tania has made it clear that she has no allegiance to Marshall. The villagers storm into the castle and set it aflame in the hopes of killing the monster. Harris arrives with Thomas's sister Julia to see Tania and Marshall/Thomas naked and enjoying post-fight sexual intercourse as the castle burns beside them. However, during their lovemaking, Marshall/Thomas begins to choke Tania as the flames consume them.

Cushing was determined to produce a film starring actress Rosalba Neri, whom he was romantically pursuing. Recalling the film's development and their relationship, Welles recalled that Neri "was turning him down, everywhere. She couldn't actually stand him; Harry was actually quite good-looking, but he was a pain in the neck because he had never lived in the real world ― and that's what she resented about him. He never worked a day in his life. So here, in my lap, he dropped the script and the money to do it. What a windfall!". Upon
