Monstrosity (1963)

Also known by its alternate title The Atomic Brain, Monstrosity is a low-budget science fiction horror film directed by Joseph V. Mascelli and produced by Jack Pollexfen and Dean Dillman Jr.. Though shot in 1958, the film wasn’t released until 1963 due to financial setbacks that left the production unfinished for years.

Plot Summary
The story centers on the wealthy and tyrannical Mrs. Hettie March, who hires the eccentric Dr. Otto Frank to perform experimental brain transplants. Her goal: to place her aging brain into the body of a beautiful young woman. To find the perfect host, she recruits three foreign domestic workers—Bea, Nina, and Anita—under false pretenses.

When Anita is deemed unsuitable due to a birthmark, Dr. Frank uses her for a grotesque experiment, transplanting the brain of a cat named Xerxes into her skull. Anita begins to exhibit feline behavior, including hissing, purring, and attacking others. After a series of bizarre and violent events, Mrs. March’s plan backfires when Dr. Frank places her brain into Xerxes instead. Now trapped in a cat’s body, she exacts revenge on the doctor by locking him in his own atomic-powered chamber.
