Imagine the plot of this one reworked for an episode of "Criminal Minds:" A business executive is stalked by a mentally unbalanced young woman and constantly shadowed by a psychopath who wants his job and life. Along the way, the girl is murdered by the psychopath, who takes pains to set up the business exec to take the fall for for the murder. In 1961, you could only go so far with such a plot. What saves the episode from being unwatchable today is George Grizzard as the psychopath. He gets scarier as the story progresses. Grizzard was a stage and screen actor who was never a leading man, but what used to be called an actor's actor. A young Leslie Nielson plays the business executive, and a fetching young thing named Natalie Trundy is his wide-eyed stalker.
