Film noir is a cinematic term used to describe stylish Hollywood crime dramas from the 1940s-1950s that emphasize cynical attitudes and sexual motivations. These films have a low-key black-and-white visual style rooted in German Expressionism and often feature morally questionable protagonists involved with crime, as well as femmes fatales who seduce the protagonist. Settings typically include bars and alleyways, and other hallmarks include heavy smoking and use of alcohol.
