Great obscure noirs and crime thrillers

Believe me, I feel guilty about it. But there is so much going on my life at present (a lot of it bad), and the temperature here on Devil's Island has been pushing 100 F for many weeks, that I find it easier to watch great movies, and read some thoughtful reviews here by others, than write amateurishly about them myself.

But I did post the shell for the topic here:

Brit Noir thread

and others are welcome to chip in until the temperature drops here, and I get my health, finances and "love-life" (I use the word ironically) sorted out a bit.
