Decker vs the replicant Roy Batty in "Bladerunner." Lots of William Blake poetry and philosophy going with that one.
Also, "The Enemy Below" in which destroyer and submarine commanders battle it out. (Mitchum and Jurgens starred.) This was copied in several Star Trek episodes. The whole movie is a fight scene.
For a short quick fights scene, you can't beat "Raiders of the Lost Ark" when Jones is confronted with a sword flourishing killer and the very annoyed Jones pulls out his pistol and shoots him.
Of course, the list is endless:
Basil Rathbone vs Errol Flynn in "Robin Hood" (the original).
The Four Musketters (very historically accurate what with the kicking, grunting, double sword use and smoky, inaccurate muskets)
"The Blue Max". How can you beat a World War 1 dog-fight?
Except to follow it with a "Fight Club" chaser....
