One of Alfred Hitchcock's classics, this romantic thriller features a cast to die for: Ingrid Bergman, Cary Grant and Claude Rains. Bergman plays the daughter of a disgraced father who is recruited by American agents to infiltrate a post-World War II spy ring in Brazil. Her control agent is Grant, who treats her with disdain while developing a deep romantic bond with her. Her assignment: to marry the suspected head of the ring (Rains) and get the goods on everyone involved. Danger, deceit, betrayal--and, yes, romance--all come together in a nearly perfect blend as the film builds to a terrific (and surprising) climax. Grant and Bergman rarely have been better. --Marshall Fine
