Storyline

Plot Summary

Visionary scientist Janos Rukh convinces a group of scientists and supporters to mount an expedition to the African continent to locate and study an ancient meteorite of great significance. He exposes himself to the highly toxic radiation of the meteorite, and while an antidote devised by Dr. Benet saves him from death by radiation poisoning, his naked touch causes instant death to others. Back in London, the benefits of the meteorite's controlled radiation offer Dr. Benet an opportunity to restore eyesight to the blind. The antidote's toxicity excites Prof. Rukh into paranoid rages as he seeks revenge against the members of his expedition, who he accuses of stealing his discovery for their own glory. Written by Sister Grimm

Trivia In 1986 actress Frances Drake recalled that the crew played a joke on star Karloff. They raised him up on a platform that was intended to lower him down into the radium pit. They raised him up high over the pit and left him there when they broke for lunch. According to Drake, the actor was a good sport about it. See more »
Goofs The film shows a clipping from a news magazine announcing that the principal characters have gone on an expedition to Nigeria to find the meteor containing Radium X. Yet in the earlier sequence showing the meteor landing on earth, it hit on the southwest coast of Africa over 1,000 miles away from Nigeria. See more »

Crazy Credits At the end: "A Universal Cast is Worth Repeating." This credit appeared on many Universal films of that era, not just "The Invisible Ray". It did not, however, appear on the cast list for the 1936 "Show Boat", which Universal also made. See more »
