THE DEVIL THUMBS A RIDE
THE 3RD VOICE (technically not a classic era noir -- 1960 -- but it's worthy)
CHINATOWN AT MIDNIGHT
THE NIGHT HAS A THOUSAND EYES
Feel free to add to this list. Scanning the studio lists in the appendices of Arthur Lyons' Death On The Cheap, I suppose there are probably at least a couple dozen more, but it's amazing how many listed in that book have been restored or at least upgraded to better prints since the book was published in 2000. It'd be nice to finish the job before we start getting those 4K copies of Double Indemnity and Out Of The Past.
