Re: My son likes the Samarai aspect...
Hmm... As far as Samurai films go, that's pretty much all the Kurosawa films I've seen. His other stuff is good too, but if your son is into the samurai aspect of it, he won't be too happy with Kurosawa's other stuff.
Another series that your son might get into is the "Samurai" series of films about [link|http://us.imdb.com/title/tt0047444/|Miyamoto Musashi], who is historically considered the greatest warrior ever to live in Japan. He's the guy who either invented or perfected the "two swords" technique, a technique he never used in a duel because he felt it made fighting too easy.
Actually, just about anything starring Toshiro Mifune is a good bet for samurai-style action. Not ANYTHING, after all Akahige and Picture Bride wouldn't really count for that. Still, you get the idea.
