Dubliners unlikely to feature in such films? (4)
I believe the answer is:
noir
If this is the answer, I'm afraid I cannot explain it.
Can you help me to learn more?
(Other definitions for noir that I've seen before include "Dark in France, like brooding films of 40s and 50s" , "(Of film or fiction) with bleak settings and cynical characters" , "cinematic style" , "Kind of dark film" , "film genre" .)
