ETA: I'd probably run it like Lost Horror Stories, with a list of films you could claim, but it would be multifandom.
Would you be interested in taking part in a film noir fic challenge?
Yes! Sign me up!
No, I'm not familiar enough with/not a fan of film noirs
No, most are too complicated to do justice to in a fic!
Maybe later, not right now!
Only if you include newer noirs like Memento
