This 1957 noir masterpiece by Jacques Tourneur stars Aldo Ray as a man fleeing a private investigator and Anne Bancroft as the barroom acquaintance who agrees to help him. Ray’s past is revealed gradually in a series of flashbacks, which are intercut with the couple’s flight and the investigator’s pursuit; by developing each narrative in a parallel space or time, Tourneur movingly articulates the theme of a character trapped by his history. The images have a smooth, almost liquid quality, the high-contrast lighting of most noirs replaced by a delicate lyricism that takes the natural world as the norm. Tourneur links this naturalism to Ray’s growing observational skills (“I know where every shadow falls,” he says), but it also contrasts with the story’s acute paranoia. 78 min.
