I think there are so many activities going on, like mountaineering. You know, you would pay good money not to have to do that, and yet there are people racing out who want to spend their spare time clambering up rocks.

The thrill I got discovering Buster Keaton when I was growing up was so exciting. He was one of the greats.

The most creative people have this childlike facility to play.

I can't tell you how scary it can be walking onto a movie and suddenly joining this family - it's like going to somebody else's Christmas dinner; everyone knows everyone and you're not quite sure what you're supposed to sit.

Nerves are always a big problem for me, which is why I loved doing American sitcoms. Because you know when you do the take in front of the audience that you're going to do it again afterwards.
