Every so often, a movie comes along that makes you question not only the choices of the filmmakers, but also your own decision to keep watching past the first ten minutes. Frankenstein Island isn’t just bad—it’s the cinematic equivalent of being cornered by a rambling uncle at a family reunion who smells like rum and wants to tell you about “the aliens the government doesn’t want you to know about,” but with zombies in sunglasses.
The Plot: If You Can Call It That
A group of balloonists—yes, balloonists—crash-land on an island. This is already a terrible start; there has never been a good horror movie that began with, “So, we were in a hot air balloon…” From there, they are captured by two old, drunk pirates who look like they’ve been holding auditions for “community theater Jack Sparrow” for twenty years.
Enter Sheila Frankenstein, the white-haired, buxom descendant of the original Dr. Frankenstein, who has apparently been spending her free time turning shipwrecked sailors into zombies who have to wear sunglasses because… reasons. Light sensitivity? Undead fashion statement? Lost sponsorship deal with Ray-Ban? We never get a clear answer.
Subplots From the Twilight Zone (and the Wine Cellar)
You’d think zombies in shades would be enough, but no—this movie piles on like a buffet plate at a diner you regret visiting. We get:
-
A 200-year-old Dr. Van Helsing lying in bed like a crypt keeper on life support.
-
A prisoner who quotes Edgar Allan Poe for no reason other than someone in the crew probably owned a Best of Poepaperback.
-
A tribe of bikini-clad Amazon jungle girls who are also descended from aliens, because why the hell not at this point.
-
John Carradine as the ghost of Dr. Frankenstein, phoning in lines about “The Power!!” like a man who’s already been paid and just wants to go home.
Oh, and the original Frankenstein’s monster is at the bottom of a pool in a cave, waiting to make a dramatic entrance that ends up being about as threatening as a damp Halloween decoration.
The Acting: Dead Eyed and Dead Tired
Cameron Mitchell plays “Clay Jayson” with all the enthusiasm of a man wondering if his check will bounce. Robert Clarke tries to bring some dignity, but you can actually see the moment he realizes he’s trapped in cinematic purgatory. Katherine Victor, as Sheila Frankenstein, struts around with the gravitas of someone auditioning for a soap opera set on Mars.
And then there’s John Carradine, who appears only as a spectral talking head, which is fitting because that’s probably all they could afford. His main role here is to serve as a mystical narrator who sounds like he’s reading the world’s weirdest bedtime story.
Special Effects: Sunglasses and Sadness
The “zombies” are just people in black turtlenecks and shades, looking like they wandered off the set of a 1981 jazz album cover. The monster makeup is so minimal it could pass for “I forgot to shower this morning.” And then there are the sets—half of them look like they were built in someone’s garage, the other half are just whatever patch of hillside the crew could shoot without getting kicked off by park rangers.
Even the dog, Melvin, seems aware he’s in a mistake. He delivers the most convincing performance in the film simply by looking constantly confused.
Final Verdict
Frankenstein Island is what happens when you take public domain horror concepts, toss them in a blender with some rum, and hit “purée” until your career is unrecognizable. It’s slow, bizarrely padded, and stitched together with the same care Dr. Frankenstein might have used if he were blackout drunk.
The only real terror here is realizing that Jerry Warren took fifteen years off from filmmaking… and this is what he came back with. Somewhere, Mary Shelley is rolling in her grave, possibly wearing sunglasses.
