Fear Chamber

Thankfully, he didn't live to see this turkey released.

The plot is simple. A scientist (Boris) finds a living rock from the center of the Earth that promises the secrets to the universe, but requires the adrenaline of terrified women to live. He realizes that the rock is a murdering creature, and suffers an episode (excusing him from having to appear in the rest of the movie until the very end.) The rest of the film is filled by bad Mexican actors and strippers wearing granny panties. Which just goes to prove, illegal aliens are just doing JObs Americans won't do, because I couldn't imagine any American wanting to appear in this tripe.

This movie would have been lost to history had it not had Karloff's scenes in it. It's too bad the Karloff estate, which jealously guards his image today, can't get this and other dubious works pulled from distribution.
