Kino Lorber's 2016 Blu-ray of this 63-minute movie features a nearly two-hour commentary with Tom Weaver, David Schecter, Dr. Robert J. Kiss and Sumishta Brahm. The latter is the daughter of the movie's director, John Brahm.
Film debut of Charles McGraw (uncredited). NOTE: Though he specialized in playing tough guys--usually cops or criminals--here in his film debut he plays a British horse groom.
This film is essentially a 20th Century-Fox knock off of Universal's monster 1941 hit The Wolf Man, even down to there being a poem recited about the title creature, which terrorizes members of a once rich family living in a foggy, cliff-side mansion.
John Howard plays Oliver, one of the title creature's early victims, and is best remembered for playing Katharine Hepburn's stuffy fiance' (alongside Cary Grant and James Stewart) in the 1940 classic The Philadelphia Story.
George Sanders was originally cast in the film, but refused to play the role that eventually went to James Ellison. Sanders was suspended from 20th Century-Fox as a result.
