Re: what is your best movie related to the martial arts
Yojimbo is great. So is seven samurai.
I would have to say that any Samurai film by Kurosawa is great.
Star Wars was inspired by the Kurosawa film The Hidden Fortress.
The Zatoichi films are also some of my favorites.
The Baby Cart Assassin series was real good.
Shogun was a classic. It's out on DVD now. Recently, I liked The Last Samurai. I didn't get the feeling it was a propaganda film though.
