Murder Most Foul is the third of four Miss Marple films made by Metro-Goldwyn-Mayer. Loosely based on the 1952 novel Mrs McGinty's Dead by Agatha Christie, it stars Margaret Rutherford as Miss Jane Marple, Ron Moody as the theater company director H. Driffold Cosgood, Charles Tingwell as Inspector Craddock, and Stringer Davis as Mr Stringer. The story is ostensibly based on Christie's novel, but notably changes the action and the characters. Hercule Poirot is replaced by Miss Marple and most of the other characters are not in the novel.
