A neo-noir (an updated version of the film noir crime films and whodunits of the 40's and 50's) is an updated noir that has a certain modernized element of style, themes or content. Film noirs and neo-noirs both usually fall under the thriller/suspense genres, and some gangster movies. Some good examples of neo-noirs are: Scarface, Dead Again, Motal Thoughts, Final Analysis, Basic Instinct, Deep Cover, Jennifer 8, Malice, The Last Seduction, The Usual Suspects, Bound, L.A. Confidential, The Black Dahlia, Batman Begins and The Dark Knight.
