Donnie Yen versus Jet Li
It's utterly beyond me why Donnie Yen is not not a household name in the west. At least, he should be as famous as Jet Li is in North America: he's cool, charismatic, lightning-fast, can do acrobatic flips without wires that don't seem humanly possible (though short on action, "Legend of the Fist" features some physical stuff that seems utterly impossible.), he is a good actor, an extraordinary fight choreographer, and he speaks English better than most other Asian martial-artist superstars (I couldn't believe it was him speaking when he was providing audio commentary for "Kill Zone".)
I used to understand the extent of Jet Li's fame because Li is super-fast. But now having watched Donnie Yen fight, I'm in awe of what this guy can do.
