People look for patterns in everything. It's what keeps us sane, I suppose. I struggle to see any patterns in my life. I think I can understand depression a bit because of my sister. My own feelings of ... I'm aware that, if you feel down, it can be strangely unrelated to circumstances around you. That's just the way life is.

My marriage has worked because I am not around much.

There is nothing better than playing a scene with John Cleese or Maggie Smith. It's electric. But I don't think I'm the sort of person who needs to have an outer ego in order to produce something. I realised that through the travel programmes.

Despite having seen a fair amount of the world, I still love travelling - I just have an insatiable curiosity and like looking out of a window.

I got my first lifetime achievement award years ago, and I was very excited, but then I got a sense of: Well, can one get a second lifetime award?

It was a strange feeling going into a church I did not know for a service that I did not really believe in, but once inside I couldn't help a feeling of warmth and security. Outside there were wars and road accidents and murders, striptease clubs and battered babies and frayed tempers and unhappy marriages and people contemplating suicide and bad jokes, but once in St. Martin's there was peace. Surely people go to church not to involve themselves in the world's problems but to escape from them.

There are people who travel because they want to push themselves to physical limits, people who walk across deserts or cycle across the Antarctic - like Ranulph Fiennes, who just does it because it's there. And then there are people like me, who are just genuinely curious about the world.
