The Sweet Smell Of Success: Kinda-noir in New York with an awesome soundtrack. Tony Curtis plays the proto-Ari Gold.
The Asphalt Jungle: One of my absolute favorite noirs.
The Wire: How come you haven't watched the rest?
Breaking Away: Low-key comedy with a sports movie finish and a young Daniel Stern. Mark Hamil was set for the lead, but turned it down cause he was suddenly hot off of Star Wars.
The Goodbye Girl: It's a pretty clever comedy with a really likeable young Richard Dreyfuss.
Casablanca, The African Queen, Key Largo, To Have And Have Not: You ever watch the Bogart canon, outside of The Big Sleep and The Maltese Falcon?
Cat City: I watched this as a kid and apparently it's a cult hit. Eastern European 2D animation! That's got to have some cachet.
At Last The 1948 Show: Kind of an ur-Python, with John Cleese and Graham Chapman and Marty Feldman.
LA Confidential: When's the last time you watched it? It's so good and should have its own sub-forum here.
Profit: It's available on Netflix! Like right now.
