The title here should be "The Big Film Noir-ish List" but I leave it as is for easy searching.
Film Noir is not a genre, rather it was a movement. The last true film in that movement was "Touch of Evil" in 1958. This list includes Film Noir, Neo-Noir, Post-Modernist Neo-Noir, and other films that were informed - either in theme or form - by the Film Noir movement.
If your favorite didn't make the list, feel free to comment so I can add them to the list.
IMDB's 75 Most Popular Film Noir Feature Films as of 1/13/18, plus some that were previously in the top 50 (http://www.imdb.com/search/title?genres=film_noir&title_type=feature&sort=moviemeter,asc)
The Fabulous Fifties: An era of identical pink pressboard suburban houses filled with smiling, apron-clad housewives. All the men wear slippers and fedoras and smoke pipes, all the girls are teenaged and wear poodle skirts, and all the boys are cute, freckle faced scamps with slingshots in their pockets. Parents sleep in separate beds and only kiss each other on the cheek.
Anyone who isn't any of these characters are either greasers, Beatniks, gas station attendants, or Elvis (who, in this era, wouldn't be caught dead in a rhinestone jumpsuit). With the possible exception of the gas station attendants, everyone on that list is a direct threat to the upright morals and values of the era and will not be afforded a spot in the basement bomb shelter
TSPDT is building a list of 1000 Noir films to expand on its previous 250 Quintessential Noirs. Following the initial collection of 100 noirs, a further 900 noir films (or films with prominent noir elements) will steadily be added (in a fairly random manner). This list will contain the full 1000 films which are the 1,000 most cited noir films (according to TSPDT's research). Please note that this list has not been and will not be ranked.
