The world needs change, change needs an activity. It has to be planted by a thought.

We live in a beauty-obsessed culture, which on one hand is absolutely fabulous, but on the flip side, is also dangerously extreme.

We live in a society right now which is the last phase of the ecosystem in terms of the old entertainment value, or the old entertainment construction, which is we've gone down to this instant gratification, instant numbers, instant understanding, instant. But it's like the exact - it has perfected itself to the instant click, when, in a way, creativity originates as a much more complex beast. So we now have to reinvent a new canvas where we can indulge in it. And that's where the digital revolution creates a whole new ecosystem of entertainment.

Film works when a director and a star have a connection. You know, when there's something telekinetic between them, there's a partnership, it's like alter egos. It's like James Stewart and Alfred Hitchcock, or Fellini and Mastroianni. I'm not comparing, I'm just saying, if you can come into a relationship where the director and star have such a bond, it's so much easier to make a movie.

And to be fair, most documentaries are half an hour too long, anyway. Let's not kid ourselves. Most movies are an hour too long. I will say that the internet has changed everything in terms of distribution and because of iTunes and other outlets like that, length is no longer something you really think about, in my opinion. It's irrelevant.

I don't do drugs, and so music very much gets me going. When I do something, I think, "If it was a piece of music, what would it be?"

Only God Forgives was very much a generation gap in a way. It was all the youth of the world that embraced it. I make films for young people. That's what I will continue to do.
