Obviously there is tremendous debate on what constitutes 'film noir' - whether it is a genre, a tone, a time period of film, etc. At times I alter my own definition. For this list however I have chosen a fairly restrictive formulation. In this effort Sunset Boulevard (1950, Wilder), The Night of the Hunter (1955, Laughton), Sweet Smell of Success (1957, Mackendrick) and most of the master Hitchcock's best known films (Vertigo, Rear Window) were left aside from consideration. So too any films that predate 1941 (The Maltese Falcon being the 'first' film noir to me). I did include considerations beyond American cinema. I also did not abide to any closing date such as 1958. Just a personal opinion - and there are many great ones beyond these ten.
