For some reason I've never seen The Long Goodbye or The Long Kiss Goodbye - I guess I just don't like long goodbyes. Sorry, that's absolutely beyond terrible, I should edit it out but I'm not going to.
American Friend is a Ripley one isn't it, I enjoyed that. Miller's Crossing is ok but I think it added ironic remove to the noir feel and little else. Man Who Wasn't There - why is that a neo-noir, didn't feel that way to me at all?
Dark City - I remember seeing that at the cinema. At the time I thought it was superior to The Matrix which had similar themes and came along fairly soon afterwards. It didn't have the same fx though and was maybe a bit more reliant on the philosophical themes which meant it was never going to be so popular - although on the other hand it had someone from Home and Away getting naked if I remember rightly which should have been a money-spinner.
Naked Lunch - I know what you're saying there, something about the feel of the mysterious man in Tangiers or wherever it is says noir to me.
LA Confidential was good, reminded me of The Big Sleep I think. I reckon I'll try the remake anyway despite your advice Crackerjack - I'm sure it's rubbish but I'd like to compare. Similarly Obsession by De Palma which sounds as though it's almost a remake of Vertigo. You have to be brave or stupid (or greedy I suppose) to fuck with films such as those.
Also this is a neo-noir I guess

And how about Who Framed Roger Rabbit? That was great when I was little, does it still stand up?
