Beginning in the late 1960's, the film noir style of film was considered dead.
Ever since then, noir style movies have popped up every once in a while. These films are called "neo-noir" films, and occasionally they have some share of success.
Some good examples of neo-noir are Chinatown (1974) and Blade Runner (1981).
These films were both mysteries, with most of the classic film noir elements. Blade Runner, was a combination of sci-fi and film noir and it takes place in the future, while Chinatown takes place in the past, and tends to stick more with the mystery element of film noir. Other notable neo-noir films are Tequila Sunrise and Body Heat.
The best example of neo-noir would have to be L.A. Confidential. L.A. Confidential is a classic noir film, with the crooked cops, mystery, death, low-contrast lighting; everything that defines a classic noir film was in L.A. Confidential. It even takes place in the same time-period as most noir films.
However, it contains special effects and sets that were not possible to create back when film noir was climaxing. This is what makes it neo-noir, although some might argue it is noir enough to fit into the regular film noir category.
One line summary:
Film noir's not dead. It's just resting for a while.
