The final fight scene from Lethal Weapon 4, which pits cop buddies Riggs (Mel Gibson) and Murtaugh (Danny Glover) against Triad hitman Wah Sing Ku (Jet Li).
Personally, I think Jet Li should have won, since he is both cooler and would logically be able to own them both, but of course the "good guys" have to win.
The opening scene from Strange Days, an interesting sci-fi/crime set in the future. An ex-cop turned black market dealer sells discs that can map one's senses around that of a person's recorded experiences, allowing them to simulate whatever they want.
