Noir emerged as a prominent American film genre in the early 1940s, distinguishable by its use of unusual lighting, sinister plots, mysterious characters, and dark themes. From The Maltese Falcon (1941) to Touch of Evil (1958), films from this classic period reflect an atmosphere of corruption and social decay that attracted such accomplished directors as John Huston, Alfred Hitchcock, Billy Wilder, and Orson Welles.
