Hitchcock’s stylish post-WWII spy thriller casts Cary Grant as a debonair U.S. agent who recruits the daughter of a German war criminal (Ingrid Bergman) to seduce a Nazi (Claude Rains) hiding out in Brazil. The political stakes are high as she complies, relaying their dastardly plans, but the emotional ones are higher as Grant and Bergman fall in love. As in all of Hitchcock’s films, the tension is stoked by masterful visual style and anchored by now-classic performances. – Lina Fisher
