Directed by Richard E. Cunha, Frankenstein’s Daughter is a low-budget, black-and-white sci-fi horror film that holds the distinction of being the first movie to feature a female Frankenstein monster—though not without some unintended hilarity. With a cast including John Ashley, Sandra Knight, and Donald Murphy, the film blends teenage melodrama with mad science and monster mayhem.
Plot Summary
Teenager Trudy Morton lives with her uncle Dr. Carter Morton, a scientist working on a serum to eliminate disease. But his assistant, Oliver Frank, has darker ambitions—he’s actually Oliver Frankenstein, grandson of the infamous Victor Frankenstein. Secretly, Oliver is experimenting on Trudy, spiking her drinks with a formula that causes her to transform into a monstrous creature at night.
As Oliver assembles a new “perfect being” with the help of his assistant Elsu, he needs a brain—and doesn’t hesitate to murder Trudy’s friend Suzie to get it. Meanwhile, police investigate a series of attacks, and Trudy’s boyfriend Johnny tries to uncover the truth. The climax reveals Oliver’s twisted lineage and the monstrous consequences of his experiments.

Behind-the-Scenes Trivia
- The monster was played by Harry Wilson, a male actor—because makeup artist Harry Thomas wasn’t told the creature was supposed to be female until it was too late. His solution? Add lipstick
- Director Cunha was reportedly so disappointed with the monster’s look that he left the set in tears
- Sally Todd’s scream in the opening scene was lifted from Allison Hayes in Attack of the 50 Foot Woman
- The film was shot quickly and cheaply, with actor John Ashley recalling it as “really rock-bottom” compared to his work with American International Pictures
