I feel awful posting this scene out of context for anyone who hasn't seen The Man from Nowhere. You should really just go watch it instead. One of the greatest action films I've ever seen.
Anyway (skip to about 2 minutes for the action to begin)...
One of the only swordfight scenes that's had me on edge from start to finish. When was the last time you saw someone in a movie or a TV show use a feint and then not immediately take a real swing (or just feint, period), just to mess with their opponent's head? It's also really rare to see two sword fighters using different types of swords and how that difference in weapon choice affects the fight. And of course it helps that it's two genuinely great actors acting their butts off here.
One of my favourite fight scenes, and the best duel from Crouching Tiger, Hidden Dragon. On one side, you've a spolit bitch wielding a magic sword, and on the other you've got a lady who outclasses her in every possible way as a martial artist, except she has no magic weapons to hand.
"Upgrade" is a pretty decent sci-fi movie that not a lot of people have seen. The scene would be slightly confusing if you haven't seen it. He has an AI chip implanted in him.
