I think it's very hard to direct foreign language actors, but Carl Rinsch found a great way. A special super visional way.

I believe, the Japanese film industry must be open.

I was a child actor, so when I started filming when I was five years old, it was a long time ago.

It was a black and white film [at first]. And then it changed to colour film, and I was surprised and culture shocked when I was six or seven years old. And then HD, then 3D now. So what's going? What's coming next? It's so exciting.

When I was eight or nine years old, I saw the TV version of 47 Ronin, played by Toshiro Mifune. He played Oishi. That was my first experience. I watched every week with my brother. "Who plays Oishi tonight? Who will play Kira tonight?" And we fought every week.

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 a lot of Samurai film in Japan, and sometimes done the choreography by myself.
