You never know really what anyone thinks about you - that's why all my closest friends are ones I've had since my schooling days when I was 5. And I surround myself with people who I trust and who know me.

There are probably only a certain number of people who can understand or tolerate how long a job will take and what demands it puts on you. And why should they? It breeds a strange kind of selfishness immersing yourself in a character for so long.

The Italians are very unmusical. If I go to a Protestant church in London or Amsterdam or listen to a black choir, I hear four-part harmony. Italians could never do that. In Italy, we all have to sing the melody because we cannot harmonise.

When I have a creative insight, there is a high. I think back in the day, I made music as much as I did because it made me feel so good. I think you could argue that there is a creative addiction - but, you know, the healthy kind.
