My three favorite noir novels are-
Phantom Lady by Cornel Woolrich
3 Million Ways to Die by Lawrence Block
Postman Always Ring Twice by James M. Cain.
There's also Stephen Greenleaf (all works out of print, alas), James Ellroy (Black Dahlia is my favorite), Michael Walsh's Exchange Alley (also out of print), the early series novels by Dennis Lehane and Big City Bad Blood by Sean Chercover. Don't be put off by the out of print status of some of these books. Guys don't buy a lot of novels, unfortunately, which is why hardboiled mysteries are having such a tough time. Go to libraries and used bookstores to find out of print titles.
For movies: the greatest noir is Chinatown. Other greats: Double Indemnity, Pick Up on South Street, Body Heat, the films of Jean Pierre Melville, etc... This is perhaps the greatest genre ever invented.
You can't go wrong with any of the films featured in this series.
