Film Noir is a French term that refers to dark films made in a stylish crime drama style popular in Hollywood from the 1940s-1950s. These films had a low-key black-and-white visual style influenced by German Expressionism. They often centered around themes of crime, murder, alienation, and corruption. Archetypal characters included hard-boiled detectives, gangsters, and morally ambiguous figures. The visual style was defined by low-key lighting that created shadows and an unsettling atmosphere through the use of unconventional camera angles and urban settings shrouded in darkness.
