Never mind purists who bemoan Margaret Rutherford's incarnation of Agatha Christie's celebrated spinster sleuth. These four British films, produced between 1961 and 64, are jolly good, regardless of their tenuous connection with Miss Marple as written, or with Christie herself. One of the films, in fact, Murder Ahoy, is an original screenplay credited as "an interpretation of Miss Marple." And two others, Murder at the Gallop and Murder Most Foul were based on books featuring Christie's other famed detective, Hercule Poirot." But no matter. The redoubtable Rutherford indelibly makes Marple her very own, or, as she proclaims to Inspector Craddock (Charles Tingwell), with whom she locks horns throughout all four films, "I am always myself."
