Grand Dame Margaret Rutherford gives a fine performance as super sleuth Jane Marple in this, the first of four films based on Christie's detective. Agatha Christie was upset with the casting of Rutherford in the role of her dowdy, inquisitive, rather passive detective who solves crimes more on what she hears from other people more than anything else. And who cannot understand her concerns, initially? Rutherford is the antithesis of the fictional Marple. She is a battleship on screen with her plump, statuesque build, her one-of-a-kind visage, her English aristocratic bearing and wit, and her anything but passive behaviour. To put it bluntly, Christie's character was only that character in name.....but....this does not detract from the film in the least for me. And I should expect that only die-hard fans of Miss Marple will not enjoy this film for it is a good mystery, has excellent character acting, a zippy score, and some wonderful witty dialogue. Most of all, it has Dame Margaret Rutherford give a larger-than-life performance that promises to bring you many smiles and some good laughs.
