Truly Miss Marple: The Curious Case of Margaret Rutherford (2012)

Margaret Rutherford's true life story is in fact much more eccentric than the most famous fictional role she ever played: Miss Jane Marple - Agatha Christie's amateur sleuth. Rutherford's version was the very first appearance of Miss Marple on the big screen and it was far removed though from the petite, upper middle-class lady in the detective novels.
