I've travelled a huge amount, but almost all of it has been through work. I spent five years stationed in London in the special services of the American Air Force, producing and directing shows for the troops, which I absolutely loved.

I have thousands and thousands of hats. Some are the most outrageous hats in the world. They are my disguise. I hide beneath them.

Don't you find that the more you know, the more you don't know and can't ever learn because there's too much stuff out there?

Well I think they broke the mould when they made me and being humble is one of my great assets.

Actors can't retire. What would they do?

We've got to find another way of producing energy.

I'm happy to be here. I'm happy to be anywhere. I'm not kidding.
