Whenever I watch a 1940's Film Noir in glorious B&W, I realize that there are several other movies that I enjoy that could have been shot without color. Here are four that come to mind:
LA Confidential
Mulholland Falls
China Town
Mulholland Drive
They had the same era, 1940's to early 1950's, dark themes, shady characters, lots of night scenes, etc. If they can "colorize" some classic black and white films, why can't they make certain color films B&W? I think this could be a niche market for "Film Noir" buffs...I'd watch them! Even better, re-release them to "Art Cinemas" to see on the big screen.
