LIke i said before, that Geisha movie was the worst.
Cast only Chinese as Geishas, the casting caused major uproars in both China and Japan. Pretty stupid, "Last Samurai" with Tom Cruise shows how a good casting can be done.
Why not ask in the country where they have been doing Ninja-movies for decades if they have a Ninja??
Kill Bill was good too.
True, but with Last Samurai the budget was big and it was Tom Cruise, plus they HAD to be historically correct. Quentin T. tends to be a stickler for detail, especially when it comes to such subgenres that Kill Bill exemplified.
I think it revolves around several factors, money, time, budget, and the director being many of them.
