Murder Most Foul (1964) stars Margaret Rutherford in her iconic role as Miss Marple, Agatha Christie's sharp-witted amateur sleuth. When a juror—Miss Marple herself—refuses to convict a man of murder, she takes it upon herself to uncover the truth. Her investigation leads her into the dramatic world of a local theatre troupe, where secrets, lies, and danger lurk behind the curtains. A delightful blend of mystery and humor in one of the most beloved Christie film adaptations.
