Jerry Warren sat on this movie for two years before playing it with Teenage Zombies. Shot in Colossal Cave in Tucson, Arizona, the monster costume looked so bad that Warren didn’t use it. Let’s think about that for a minute. An effect so bad that Jerry Warren wouldn’t use it.

Professor Millard Wyman (John Carradine) has sent Paul Whitmore (Allen Windsor), Craig Randall (Robert Clarke), Lauri Talbott (Sheila Noonan) and Dale Marshall (Phyllis Coates) to the bottom of the ocean, but their vehicle becomes lost. They swim — in scuba suits at crushing depths — into a cave where only Matheny (George Skaff), an old sailor, is still alive.

Professor Wyman’s brother, Jim (Joe Maierhauser), has luckily built another vehicle, because Matheny is looking at the ladies like a man who has been in a cave for more than a decade and suddenly has a gypsy girl from” Beast from the Haunted Cave” and Lois Lane right within staring distance. Before he can say, “You know, I killed a man,” a volcano goes live, he dies under some rocks, and all the white scientists celebrate their good fortune above the surface, and no one gets the bends.

Warren sold this with “A Nightmare of Terror in the Center of the Earth with Forgotten Men, Monsters, Earthquakes and Boiling Volcanoes!” I mean, yes, it has those things, but it’s…maybe not as exciting as the ads make it sound. The petrified world is the movie itself.
