When you try to be true to the script, changes occur. A script is there to show us a certain direction. But when you actually have the actors in and you start shooting the movie, you have the actor say a line and it doesn't sound right so you change it and make it different. It's the script that gives birth to these changes and the more you try to stay true to the script, the more that happens.

At some moments, you feel attracted to someone of the same sex, even if it's not sexual. You just want to be like him.

In Japan, violence isn't as controversial as it is in the West. Pornography is more restricted, but it's not hard to make a crazy, extremely violent film.

I don't mind ratings boards. As a viewer, you have the right not to see a film.

When you are completely satisfied with what you have made, you're pretty much done as a director. So when that happens, that'll sort of be the end.

You can't really make something or make a movie and feel all through the process that it's a painful thing. It's not possible to do that.

And if I'm running away from something, I try to make myself face it and overcome that initial fear. As a director, I don't think it's possible to make a movie that you really don't want to make.
