Storyline

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.

Goofs

The story is frequently advanced by the old "newspaper headline" gimmick. About 45 minutes in, one newspaper tells of the "Benet expedition," but in the small print the name is misspelled as "Bennet." See more »

Karloff/Lugosi...Need I Say More
17 November 1999 | by (NC) – See all my reviews

The Invisible Ray is an exciting story about an overworked scientist who works effortlessly in his Carpathian castle looking for secrets of the universe. Boris Karloff plays the scientist Janos Ruhk who travels with a band of other scientists to Africa for the spot where an unidentified element landed centuries ago. Karloff is very good as the scientist who accidentally poisons himself with this new radioactive element. Karloff is obsessed with the idea that his fellow travelers, amongst them the stately Lugosi as Dr. Benet, are after his honors and secrets of this new find. Because of this, Karloff goes on a maniacal murdering spree of his former friends. There are many good elements in this film, most dealing with the rather interesting story of science gone amok. Lugosi is good too, although his role is not very big. I must agree with many that this pairing of the horrific duo is a second to The Black Cat. Nonetheless this is a fine Universal science fiction/horror film.
