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.

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 change somebody completely, deep inside your nature. But I think what I did was admit to myself what kind of a person I was, and sort of get into the idea that that's who I was. And I think preserving that part of myself really helps me make movies.

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

Every medium has its own kind of freedom. I don't want to just cross from one to the next. I want to enjoy the freedom each one has. Sometimes, you can do something for TV that you can't do in the cinema.

The reason I like incorporating the Yakuza into my movies - all their actions, everything they do, you can say 'It's ok because he's a Yakuza'. Changes happen very quickly in their world. If you were trying to make a movie about politicians, it would takes years and years for something to change; whereas for Yakuzas, it could only take one night and things can change dramatically.

Filmmaking is not a balancing act, although some directors think it is. I don't believe in it. I like ups and downs. They're the best way to translate my feelings to the screen.
