The Invisible Ray (1936)

An astronomer (Boris Karloff) with controversial theories travels to Africa with two other scientists (Bela Lugosi, Walter Kingsford) to locate a meteorite that crashed to Earth a billion years ago. He discovers the meteorite's location and conducts experiments in secret but when he begins to glow in the dark, he realizes the deadly power of his discovery which he call Radium X. Directed by Lambert Hillyer (DRACULA'S DAUGHTER), this is an okay addition to the Universal classic horror library. While I can't get too enthusiastic about it, it's well made with some solid performances by horror icons Karloff and Lugosi. Lugosi has one of his rare good guy roles and the film allows Karloff some leeway with his character. He's not purely evil, he has a conscience even if it is cloudy. The film is actually more science fiction than horror but since it's a mixture I suppose that's a moot point. With Beulah Bondi, Frank Lawton, Violet Kemble Coooper and Frank Reicher.
