Top spot goes to the old samurai in "Last Samurai" that watches over Tom Cruises' character. Grizzled, quite, and totally a bad dude. He comes out of no where to chop down a host of ninja half way thru the movie. A close second, from my favorite martial arts film, is Alex Grady from "Best of the Best". He's part Rocky, part veteran top kick arch-type, and also a formidable character.
