There have been many very good modern noirs that seem to get missed on these kinds of threads:
Brick - my favourite Rian Johnson film and a highly stylised noir transferring the likes of Bogart and Lake to modern day high school.
The Last Seduction / Red Rock West - or, almost any John Dahl film from the 90''s
Mulholland Drive - actually quite a straightforward neo-noir once you find the centre of the spiral structure.
Body Heat - probably the origins of the neo-noir movement. Both sexy and hard-boiled as hell, it still stands (even in the company of his SW and Indy output) as one of Kasdan''s best works
Nightcrawler - not only Make Gyllenhaal''s most impressive performance, but pure noir through and through even if it evades the standard mystery/police tropes
But in the end when it comes to the peak of noir film makin... forget it, Jake. It's Chinatown.
Hugo - maybe I'll just sit here and bleed at you
