Film noir is a style of film characterized by low-key lighting, bleak urban settings, and corrupt, cynical characters who find themselves entangled in the criminal underworld. This dark genre, which gave rise to the film archetypes of the hardboiled private detective and the femme fatale, was especially popular in Hollywood in the 1940s. Classic examples of film noir include The Maltese Falcon and The Big Sleep. Who first coined the term film noir, and what does it mean? Discuss
