Film noir is a term used to describe crime drama movies from Hollywood that are often focused on sex, crime, and corruption.
Film noir movies were mostly made from the early 1940s to the late 1950s in the United States, and they were usually filmed in black-and-white. The term "film noir" comes from the French term for "black film" or "dark film". Film noir movies include many different genres of movies, such as gangster movies, police movies, and detective movies.
Film noir movies were often filmed so that there were many dark shadows in the movie, even on characters' faces. The Hollywood film noir movies were influenced by German film directors such as Fritz Lang, who used dramatic lighting techniques. Another influence on film noir movies was 1930s French books or movies about heroes who would die at the end of the story or stories with sad endings. Film noir movies were also influenced by crime fiction, such as the detective and crime stories by Dashiell Hammett, James M. Cain, and Raymond Chandler.
