Sometimes creativity is a compulsion, not an ambition.

If Nick Broomfield never found anyone with affection for Courtney Love, it's only because he conspicuously avoided the countless friends, colleagues and fans who appreciate her talent and admire her as a person. But then, why would Broomfield have opened up his film to those of us who work with Courtney and are close to her when there are so many bitter left - behinds and desperate attention - seekers eager to validate his attack on her character? Inquisitors in every age, scared of forceful women, have used all kinds of half - baked testimony to whip up chants of 'Burn the witch!'

Everyone thinks that Fight Club is a very important and successful film, but it was a massive box-office failure. Massive. It was a big flop by any commercial-release standard. And it's been a huge hit on DVD. Everything that movie has become has been on DVD. So you can't stake your sense of creative success on this whole box-office-performance matrix, because if you do, you're going to be disappointed most of the time.

When I look at the directors that I really love, who really develop their films over time, they're almost always the ones who go back again and again and again at the same investigations. I think that when somebody has a theme they go after, it's fun to service that. It's like, "I know you now. I know what you go at." It helps you locate yourself a little bit quicker in their world.

There are so many people who are conscientious and caring about others. I've spent time working in countries where I really noticed the absence of civic concern, care for other people. I've been in other countries where I feel a palpable, almost tooth-and-claw attitude between people - Machiavellian, me and mine. And you can take for granted being here, with all the bloviating and the media, on a day-to-day level, people in this country are really pretty concerned for each other.

Making really great music, making really great films, writing great books is an antidote to all of that. And, as people, as artists, some of the massive disruption that technology is causing is so exciting, the way that people can share creativity now.

I think the consensus among our generation and people younger than us is that we do have a defining challenge in the moment, so I do like being involved in something bigger than the finger-doodling I do in art. It stimulates your brain in certain ways.
