I like to be busy. I once shared an agent with the late Sir John Gielgud, who, at 96, was apparently still ringing up, saying, 'Hello, Gielgud here, any work?' Good on him. We've got to keep working. If we retire, there'll be nobody to play the old wrinklies, and that would be a dreadful shame.

It is only when you watch the dense mass of thousands of ants, crowded together around the Hill, blackening the ground, that you begin to see the whole beast, and now you observe it thinking, planning, calculating. It is an intelligence, a kind of live computer, with crawling bits for its wits.

I love rehearsing because in rehearsals there are no mistakes, nothing is wrong, some things apply or lead you to focus on the character and the things that don't apply are equally valuable because they lead you to towards what does.
