It's a Samurai story [47 ronin], so if we change too much Japanese audiences will have strong against feelings to the film. It's not good.
I've done Last Samurai in Japan, in LA, in New Zealand. Even in Japan it is very hard to shoot, because there's been so many changes. Only around a temple can we shoot.
This is almost the most famous story The last samurai - Samurai story - in Japan.
I've done a lot of Samurai film in Japan, and sometimes done the choreography by myself.
