Murder Most Foul is the third of four Miss Marple films made by Metro-Goldwyn-Mayer. Loosely based on the novel Mrs McGinty's Dead by Agatha Christie, it stars Margaret Rutherford as Miss Jane Marple, Bud Tingwell as Inspector Craddock, and Stringer Davis (Rutherford's real-life husband) as Mr Stringer. The story is ostensibly based on the original Christie story, but notably changes the action and characters.
