Film noir refers to stylish 1940s-1950s Hollywood crime dramas known for their cynical attitudes and sexual motivations. The genre originated in the 1940s and is associated with a low-key black-and-white visual style. While initially American productions, film noir has been produced worldwide since the 1960s despite using different directors and writers, each retains attributes of the originals. Neo-noir films are modern versions that pay homage to classics like those directed by Jean-Luc Godard. Visual styles include low-key lighting that creates dramatic shadows, sometimes obscuring faces in darkness. Plots typically involve crime like murder motivated by greed or jealousy, featuring morally questionable investigators in urban settings.
