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. Hercule Poirot is replaced by Miss Marple and most other characters are not in the original story.
