I've met actors where you think, if only you could just clean up your act and get it together, people would want to work with you. Some people are so difficult, it's just not worth working with them.

Laurence Olivier said if you have ambition to be a serious classical actor, you must be as fit as an athlete. For me, the breakthrough was going to live in California. I exercised. I drank less. It was one of the things about California that had a positive impact on me.

I think I came back from America a funnier and nicer person than I went.

But as I grew up as a child, falling in love with the theater and Shakespeare, my heroes were Sir Laurence Olivier and Sir John Gielgud.

What identifies an individual as a king is how other people behave towards him. All authority is assumed, and if other people don't accept your authority then you don't have it. Perhaps the critical thing to being a convincing figure of authority is actually not to try too hard.

I came to feel very, very sentimental about those sets, which is ludicrous, because they represent everything which is transitory and insubstantial. It's absurd that one should feel sentimental about timber and canvas.

I know it feels like two steps forward and one step back, but we are making progress. In my lifetime, I have lived through one World War, I have lived through the end of Apartheid in South Africa, the pulling down of the Berlin Wall. I have experienced what I never thought I would have experienced, which is a pretty workable peace in Northern Ireland, and I experienced a unified Europe - until the Conservative government got its hands on the idea that in order to appease a few back-benchers they would hold a referendum, what a disastrous idea.
