'The Fight Club' DVD is great. I like anything that has really good extras because as an actor, it's really great to see the behind-the-scenes stuff and see how different actors approach their particular project.

When I did a high-profile project, I was not the developer of it.

I'm a Sufi Muslim, I would say. I believe in using the medium to create a good vibration because art is so important to society. Some projects I don't do because I feel that it's going to create a bad vibe. I don't do propaganda films that are anti another religion, anti-Muslim or anti-Hindu.

I usually work on a film soundtrack for two years, turning in a song every few months, and that keeps my creative energy high, because I'm constantly rotating projects. The trick is to make sure I don't work too hard and get exhausted.

Some things are very low profile, but if they excite me creatively, I accept them. Sometimes there are high-profile projects, and you have to do it. We all have human limitations. It is a painful decision to turn things down. Even accepting 'Slumdog Millionaire' was a decision that I had to sacrifice another project.

One of the hardest things about being a musician is finishing a project and then having to wait three or six months to publish it and to do all the sort of promotional behaviour.

When I was growing in the Callope project, we had an oval parkway. Pavement ran around this whole thing. We'd skate or ride bicycles. There were benches and trees out there. It was paradise to us. They finished building it the same year I was born.
