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.

I've been making movies for a long time. The Japanese way of making movies has become second nature to me. To get away from that, I really try to surround myself with younger staff and approach making movies not like a veteran of the industry but always as a beginner and a rookie.

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.

I don't know if I would call it therapy, but filmmaking is really the only thing I know how to do. For me, making movies is a way to bring on change for myself, and I really enjoy that part.

I don't make rules myself. I didn't study enough to be able to make them. I'm too stupid. I spend my whole life making movies, so I have to enjoy it. Even at times when we had a very tight and difficult schedule, it was always enjoyable. Of course I wonder if the film will be successful afterwards. It's wonderful if a film becomes successful as a result of the enjoyment that we had

If you're trying to be realistic and bring real life to the screen, you are going to have different elements. That's what I'm trying to do. As I make the movie, different elements come in naturally.
