NOTE: There is a new and improved version of this list currently being compiled. It is recommended to switch to that version!
aka The Big List of Noir Films and/or Films with Noir Elements
I decided to make a more comprehensive list of "noir films" based on TSPDT which seems to be popular on Letterboxd. Basically in addition to the 250 Quintessential Noir Films list TSPDT also compiled a list of an additional 500 films that they found cited as noirs. They divided these 500 films into three categories: A, B, and C. They also released a list of Non-American Noir Films, a Noir Precursors list, and a Neo-Noir / Modern Noir list.
