This is one of my favorite episode of The Twilight Zone. I originally shared it two years ago but it has subsequently been taken off of YouTube. At first, that upset me but then I realized that it gave me the perfect excuse to share it again!
In The Howling Man, American wanderer Dave Ellington (H.M. Wynant) comes across a castle. There’s a man (Robin Hughes) being held prisoner in the castle. Brother Jerome (the great John Carradine) explains that the man is the devil. The man says that Brother Jerome is crazy. Dave Ellington has to decide who to believe.
This well-acted, dream-like episode was written by Charles Beaumont and directed by Douglas Heyes. It originally aired on November 4th, 1960.
