Night Monster is a 1942 American black-and-white horror film featuring Bela Lugosi and produced and distributed by Universal Pictures Company. The movie uses an original story and screenplay by Clarence Upson Young and was produced and directed by Ford Beebe. For box office value, star billing was given to Bela Lugosi and Lionel Atwill, but the lead roles were played by Ralph Morgan, Irene Hervey and Don Porter, with Atwill in a character role as a pompous doctor who becomes a victim to the title character, and Lugosi in a small part as a butler. The film is in many respects a remake of Doctor X, with virtually the same denouement. Both films also feature Atwill as a doctor.

Neither Ingston nor Miss Judd welcome her presence, but must contend with keeping her overnight until her car can be repaired. Following dinner, at which Ingston's conviction that the three doctors are directly responsible for his current condition becomes evident, the party witnesses an exhibition of materialization of an Egyptian skeleton by Agar Singh. Dr. Harper is forbidden to meet with Margaret. Then, one by one, the doctors are frightfully killed as they prepare for bed. Suspecting Ingston, Dick and Police Captain Beggs confront him in his room, but discover he is not paralyzed but a quadruple amputee. Suspicion then falls on Laurie, who was last seen driving a murdered ex-employee of the household back to town, but he, too, winds up dead. Ultimately, Dick
