Sometimes I intentionally cut it off. I just want to be in silence, especially when I'm traveling. I watch movies without sound.

Your best success comes after your greatest disapponitment

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.

Since I worked with Danny Boyle before on Slumdog Millionaire, we have great success and everything. So, when I first got the script and the screenplay of Simon (Beaufoy) and I was reading it, even before the shoot, some kind of sounds came into my mind and I put some stuff [down] and sent it to Danny when he was cutting the movie.

Each one of us has our own evolution of life, and each one of us goes through different tests which are unique and challenging. But certain things are common. And we do learn things from each other's experience. On a spiritual journey, we all have the same destination.

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.

There have been predictions that the world will come to an end on 21.12.12. But I look around me and I see so much scope for hope.
