Who directed the 1946 spy film noir Notorious?

Alfred Hitchcock directed the 1946 spy film noir Notorious.

Hitchcock also produced the film, which stars Cary Grant as U.S. agent T. R. Devlin, Ingrid Bergman as Alicia Huberman, and Claude Rains as Alex Sebastian. The story follows an espionage operation in postwar Rio de Janeiro, where Alicia is asked to infiltrate a group of German émigrés and becomes entangled in a dangerous romantic triangle.

Notorious is often remembered as both a suspense picture and a sophisticated love story. Hitchcock’s direction turns ordinary objects and social situations into sources of danger, including a key, a wine cellar, and a party sequence whose tension grows through carefully controlled camera movement.

The screenplay was written by Ben Hecht, while Ted Tetzlaff handled cinematography and Roy Webb composed the music. Notorious was released by RKO Radio Pictures in August 1946 and later entered the United States National Film Registry in 2006 for its cultural, historical, and aesthetic significance.
