Alfred Hitchcock’s 1953 adaptation of Frederick Knott’s dinner-theater warhorse about a fading tennis champion (Ray Milland) who arranges the murder of his wife (Grace Kelly). The film is confined almost entirely to a cramped apartment set—a constricted space that takes on a highly expressive quality in the picture’s original 3-D version. The screenplay tends to constrain rather than liberate Hitchcock’s thematic thrust, but there is much of technical value in his geometric survey of the scene and the elaborate strategies employed to transfer audience sympathy among the four main characters. With Robert Cummings and John Williams.
