It was a dark and stormy night….yes, a classic beginning but it moves from there into interesting and entertaining territory. Boris Karloff is very good as Dr. Rukh who was ridiculed by his fellow scientists but then make an amazing discovery that proves his critics wrong. His adventures take him to Africa and back, along with Bela Kugosi as Dr Benet who has ambitions of his own. Lugosi gives a performance that is equal to Karloff's and the two of them work well together in this movie. The rest of the cast also adds quite a bit to the film as well. The only negative is the way the African natives are portrayed in the film. It borders a bit on racism but is typical of films of this period. It's not so bad, however, that it cannot be overlooked.
Director Lambert Hillyer [Dracula's Daughter] keeps things moving at a nice pace and the screen play by John Colton is intelligently written science fiction. The length of the film is just about right as well at 80 minutes. Sometimes less is definitely more.
For those who enjoy the finer points of horror filmmaking, the stupendous Jack Pierce did the makeup, although I hope he was not responsible for Karloff's Tony home perm. It was a tragic choice, indeed.
Enjoy this sweet little piece of 1930's Sci-Fi Thriller. The Invisible Ray may not be well-know to everyone but it definitely deserves more attention from horror movie fans.
RATING: Very Good.
