The Philosophy of Film Noir (The Philosophy of Popular Culture) by Mark T. Conard

A drifter with no name and no past, driven purely by desire, is convinced by a beautiful woman to murder her husband. A hard-drinking detective down on his luck becomes involved with a gang of criminals in pursuit of a priceless artifact. The stories are at once romantic, pessimistic, filled with anxiety and a sense of alienation, and they define the essence of film noir. 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.
