These are the Rad instruments that are dying out in India. So, it's going well and I think now we are increasing the number of kids we have taught and of course we are helping out with other things too. It's based in India now. [The idea is to] perfect it in one place and then we'll expand.

I didn't see it coming at all. I just wanted to have this new experience with this team of Danny Boyle, Christian (Colson) and Simon (Beaufoy). It was like an excursion for me from my normal routine and the Indian movies I do and that helped.

The more you know the less you talk.

I've never watched Trainspotting. I just know it's a very critically acclaimed film. In fact, I've never watched any of Danny's movies [means before he met him]. I just worked with him and felt the energy of what he is about initially before I do something. In a way, I think that's why we have discovered each other rather than replicate something else.

Certain things are done intentionally opposite - like there's no sound at the end or synthesizers or all that stuff. Anything that drowns the movie, no. Anything that makes you sit up and watch it, yes. So, some are expecting a very sad theme going on.

Because when you work with a different team, the expectations are different and then you deliver in a very different way. You look back at it and you're proud of yourself. And when the same people come in and you do the same thing, it's boring. You could re-envision it again and again but when the new chemistry of ideas comes in, something happens as a team.

That was a very different emotion and I felt Dido's words would be good and I had a template with my voice in it. Then, when he heard it, he wanted both our voices together in it and that's the scene when he sees the boy and then he gets charged to go on that final cutting effort.
