1. Hard Boiled- no question in my mind. Chow Yun-Fat's body count in this movie has to be a couple hundred, at least. 2. Infernal Affairs- I love this movie, was disappointed when Scorsese remade it. 3. Run Lola Run- great movie, underrated 4. Yojimbo- excellent film, features Toshiro Mifune in an iconic role 5. The Maltese Falcon (1941) - started film noir, Bogart in one of his best roles (Casablanca & The Big Sleep are his others, imo) 5.-tie- The Usual Supects- Keyser Söze is an all-time great character If you say Hard Boiled and The Maltese Falcon don't count because the main guys are fighting against gangsters, then I would probably throw Scarface (1983) in there, despite the fact that it drags at many points and should be an hour or so shorter, and probably Lock, Stock and Two Smoking Barrels or maybe Mean Streets, Menace II Society, or The Godfather I or II. I like Casino, I just think it drags even worse than Scarface. Goodfellas is weak, imo. I actually prefer Donnie Brasco and Carlito's Way if you're looking for movies about snitches. edit: fixed formatting. I forgot that yuku doesn't work with Safari.
