to clear things up
a lot of people mix this movie with the new lasst samuray, lost samuray, and hell knows what.
this is a movie where an american veteran is hired to teach chineese force to use modern weapons, gets kidnapped by a samuray-gang, learns their ways and then helps them to fight against the army he was supposed to be training. so stop mixing this movie with some bad ones.
