Film noir is a cinematic term used to describe movies from the 1940s-1950s that featured pessimistic themes, ambiguous morality, and cynical characters. It is characterized by stylish crime dramas and an emphasis on sexual motivations and fate. While the definition was disputed, one author defined film noir as "always about sex, violence, and money." Some classic examples are Casablanca and films by Alfred Hitchcock from this era. More recent films noir continue to use elements like low-key lighting, bleak urban settings, and corrupt characters.
