From "The Psychotronic Encyclopedia of Film":
Advertised as "Guaranteed to frighten!" In one of Republic's last productions, mad scientist John Carradine lures mentally disturbed patients to his house in Georgia for treatment. He uses them for experiments with eternal life which always backfire and cause his basement to fill up with mutants. His servant Lobo (Tor Johnson) turns on him and rescues sexy Allison Hayes and her new love, escaped convict Myron Healy. Originally co-billed with Beginning of the End. It's similar to, but more fun than the previous year's period horror film, The Black Sleep.
From "Leonard Maltin's Movie and Video Guide":
*1/2. Mad scientist Carradine's experiments in immortality have resulted in only a basement full of deformed morons. Don't you join them.
From "The Horror Film Handbook":
A mad scientist and his assistant experiment on humans to discover the secret of eternal life and end up with a cellar full of grotesque monsters. Poorly scripted, directed to match with even the reliable Carradine unable to rise above the surrounding awfulness.
Review from "Variety" magazine, 1957:
"There's nothing to recommend this one beyond it's cheapness. Fodder for a very unsophisticated market."
This film also contained one of Tor's rare spoken lines: "Time for go to sleep."
