All-star whodunit combines glamor and mystery
As “The Mirror Crack’d” opens, we are watching a black-and-white mystery movie called “Murder at Midnight.” A police inspector has assembled a group of people at a mansion and is about to announce the killer when the film breaks and the actual setting is revealed in color — a social hall in a vicarage in St. Mary Mead. The vicar, doubling as projectionist, assures the small assemblage that he will repair the broken reel and continue the movie, but one woman in the audience sees no reason to wait. As she gathers up her belongings and makes her way out, viewers ask her opinion about the identity of the killer. With methodical precision, she analyzes what has transpired, eliminates suspects, and tells the crowd who the fictional killer is.<br /><br />Thus are we introduced to Miss Jane Marple (Angela Lansbury), amateur sleuth and one of Agatha Christie’s most famous characters. Set in the early 1950s, the story focuses on an American movie company that has come to the small English village to shoot a period film starring Marina Rudd (Elizabeth Taylor), making a comeback after years off the screen, and directed by Marina’s husband, Jason Rudd (Rock Hudson). During a reception at the country estate they rented, one of the guests (Maureen Bennett) suddenly collapses and dies. Miss Marple’s nephew, Scotland Yard inspector Dermot Craddock (Edward Fox), comes to the village to investigate, and he and his aunt speculate on the strange circumstances of the woman’s inexplicable death.<br /><br />As whodunits go, “The Mirror Crack’d” checks all the boxes — a lavish setting, plenty of colorful characters, red herrings, and surprise revelations. Added to this is considerable star power. Along with Elizabeth Taylor and Rock Hudson, the movie features Kim Novak as Lola Brewster, a longtime rival of Marina, Geraldine Chaplin as Marina’s personal assistant, and Tony Curtis as the producer of the movie and Lola’s husband.<br /><br />Taking on the role played earlier on screen by Margaret Rutherford, Lansbury is excellent as Miss Marple but is too often off screen, with most of the action concentrated on the filmmakers. Each of Lansbury’s appearances peps up the sometimes ponderous narrative with Miss Marple’s nosiness, love of gossip, and wit balancing the murder investigation.<br /><br />Taylor is perfect as a glamorous movie star and is photographed beautifully in striking outfits befitting Marina’s celebrity. Marina has a tragic back story, which humanizes her and explains her absence from the screen for so many years. Her new movie, in which she is to star as Mary, Queen of Scots, is her hoped-for comeback, so much is riding on its success.<br /><br />“The Mirror Crack’s” looks great, with its picture post card village, period costumes, and opulent interiors. Director Guy Hamilton (“Goldfinger”) successfully moves the action to avoid an old-fashioned, static, drawing- room mystery look. He takes full advantage of the locations and sets the action in a number of diverse settings, including Miss  Marple’s thatched-roof house, the movie set, rooms at the estate that’s hosting Marina and Jason, and an important flashback at a theater.<br /><br />The movie is great fun and works as both whodunit and character study of a quirky woman who is challenged by what confuses others and is an old hand at solving mysteries. As with her fictional predecessor Sherlock Holmes, we delight in seeing her strip away the layers and uncover the truth.<br /><br />Bonus materials on the Region A PG-rated Blu-ray release include an audio commentary, TV spots, and theatrical trailers.
