i think the best would have to be bruce lee's enter the dragon. it was the first martial arts movie i saw and it was and will always be the best. heroes of the east, the last hurrah for chivalry, legend of the drunken master, ip man, city of violence, the protector, and chocolate are all a very close second though. and an honorable mention would have to go to ninja assassin because its the only one i've only seen once.
