For a fun heist movie, with sneaky disguises, creeping around buildings in the dark, and Dramatic Confrontations, Dhoom 2 is a blast. Basically, they took a cop movie franchise, got even more famous actors to play the criminals, and turned it into a ridiculous and kind of awesome heist movie.

Black & White/Pi Zi Ying Xiong is a Taiwanese cop-and-triad TV series, but it's a little heavier on the cops than the triad members, so YMMV.
