Dial "M" for Murder (1954)
The first of Hitch's so-called "blonde films," this double-crossing plot is among the filmmaker's best. Grace Kelly is a woman torn between her husband (a handsome but murderous Ray Milland) and her new love (a dashing but philandering Robert Cummings). When Milland learns of the affair, he decides to blackmail an old acquaintance into murdering his wife. Things go a bit haywire, so Milland switches plans and attempts to frame his wife for the murder of the would-be assassin. Everything seems to be going according to Plan B, until an inspector starts snooping around. This film was originally done in 3-D, but switched to 2-D soon after. The 3-D version of this thriller is now available as a reissue.
