I am surprised that this piece of awesome pulp action is a total obscurity. It has death rays, mystic yogis, a beautiful princess, an Egyptian temple, hypnosis, telepathy, a sandstorm, Bela Lugosi as a James Bond villain, etc., etc. The special effects are superb. The sets are impressive. James Wong Howe's cinematography is beautiful. It's like Enter the Dragon in being the complete pulp movie.
