Film Noir is a cinematic term used to describe a specific type of film in Hollywood: stylized crime dramas, particularly those that have a mood of pessimism, fatalism and cynical attitudes. The 1940s and 1950s are regarded as the “classic period” of American film noir.

Some examples are=

In a Lonely Place (Nicholas Ray, 1950)

And Double Indemnity (Billy Wilder, 1944)

There is also the “Neo Noir” type of film which contains the visual style and themes of classic film noir but with an added modern sensibility. They also contain graphic displays of violence and sexuality.

An example is Blade Runner (Ridley Scott, 1982)
