Almost anything by Hawks during those years. Or Hitchcock. Almost anything with Bogart. Or Grant. Or by Wilder.
Tons of noir films skirted the rules.
Look, I’m not a fan of the Hays code but some of those movies were to me better because of what they had to imply.
This is after the Hays code but as an example I recently watched the original 3:10 to Yuma and the remake. I hated the remake. What appeals to me about Elmore Leonard stories is that despite being about bad guys, they have a degree of charm to them (Out of Sight, Justified, Jackie Brown, Get Shorty,etc). The remake took all of the charm out of the original and replaced it with graphic violence and cruelty.
