The Haunted Strangler (also known as Grip of the Strangler and originally titled The Judas Hole) is a 1958 British horror film directed by Robert Day. It was adapted from "Stranglehold", a story which screenwriter Jan Read had written specially for Boris Karloff, and was shot back to back with producer Richard Gordon's Fiend Without a Face, with both later being released as a double feature by MGM.
