I actually like the list as it stands with a few minor things. "The Matrix Reloaded" sword fight was more camera than fight and could be removed for anything Zorro in any incarnation. (TV, movie, serial).
"Afro Samurai" could be pulled only because no one actually swings a real sword. Sure the animation was alright, but, no one actually sweats, moves or has the possibility of getting hit with a stray bad swing. Heck, "Mighty Moron Power Rangers" belongs on the list ahead of this, and that makes me feel very, very dirty for saying that.
Glad there was few Asian inspired fights, frankly the one that's on here makes my blood boil, but it's no secret I hate wire-fu in all it's unbelievable glory. The "Last Samurai" sword fight always rubbed me the wrong way, there are some brilliant battle sequences in that movie but the whole "See the fight" slow motion action before the actual fight was a little cheesy to me. One I would have loved to have seen was the first major fight scene from "Seven Samurai"; simple, brutal, beautiful (and it has Tashiro Mifune).
I would have loved to have seen anything from the 1970s "Three Musketeers" movies. Some of those scenes were pure brilliance, heck even the Walt Disney version had a couple of decent ones, but the newest one just blew chunks.
I also agree that "The 13th Warrior" or "Kingdom of Heaven" fights would have been good additions.
