I wanted to be an explorer, but gradually found the world had been explored and that there was nowhere left, really. Once they climbed Everest in 1953, when I was 10 years old, I thought, 'Well, that's pretty much it now.' But the idea of travelling and exploring and adventure was very strong.

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.

I mistrust total competence. I've always felt life is a series of small disasters we try to get through.

The human race should just slow down and think about what it is doing.

You don't ask people about the immigration policies of the U.K. or their country's agricultural policy. Instead, you talk to them about the meal they're eating or their family, and from that you get the sense of another human being, someone we can all relate to.
