Godot is whatever it is in life that you are waiting for: 'I'm waiting to win the lottery. I'm waiting to fall in love'. For me, as a child, it was Christmas. At least that eventually came.

When you grumble about a taxi being dirty, people your own age will absolutely agree with you, whereas younger people say, 'You should be so lucky to have a taxi - I walk to work!' So I have lots of young friends, who fortunately don't treat me as a guru, a person that knows all the answers.

I'd never read 'Lord of the Rings' until I was asked to play Gandalf, so I didn't really know it was a frightfully famous book.
