I loved Ronin Warriors. A live action movie of that would be epic. On a side note, I tried watching the japanese version of it and wow.. the english version was completely edited.. even names were swapped with different characters.
I think he did good in it too. I've seen it a couple times now and its one of the few movies hes in that I actually bought on dvd. I don't care for most of his other roles, hes usually all action and no substance. I think Keanu needs to redeem himself acting wise. I didn't care for him in the Matrix movies, but the guy does have some acting skill, he just keeps getting roles that don't really seem fit for him IMO. Although he owned in Bill & Ted.
