The term 'Film NOIR' (4 letters) is a shadowy genre of film that originated in the 1940s. It is characterized by its dark and cynical themes, as well as its use of low-key lighting and black-and-white cinematography. Film NOIR often features stories of crime, mystery, and moral ambiguity, and often includes elements of romance and suspense. The genre has been influential in many other genres of film, including neo-NOIR and modern crime films.
