J. Lee Thompson’s Cape Fear (1962), starring Gregory Peck and Robert Mitchum, is a classic psychological thriller about a family stalked by a vengeful ex-convict. Mitchum’s chilling performance as Max Cady turned the film into one of cinema’s great portraits of obsession and menace, while Peck plays the lawyer trying to protect his family from escalating terror. A landmark in suspense cinema, it remains a touchstone of the stalker-thriller subgenre.
