I always feel emotionally engaged in productions. If I ever get to the point where I don't feel emotionally engaged, maybe I should stop. You have to make each play an event. Whether that's star leading actors or the concept behind the production.

What's depressing, in a way, thinking of Margaret Thatcher legacy - and she was no doubt great in many ways - but the arts in the UK are still having to justify that it is a profitable business rather than a frivolity. It's one of the greatest UK exports, one of the reasons people come to the UK, and yet we're still having to justify our existence in terms of funding.

I went to a Jesuit school and they did a William Shakespeare play every year. I got to know Shakespeare as parts I wanted to play. I missed out on playing Ophelia - it was an all-boys school. The younger boys used to play the girls, I played Lady Anne in Richard III and Lady Macbeth, then Richard II and Malvolio. I just became a complete Shakespeare nut, really.

I don't think Vladimir Putin goes to the theater enough to even deign to think there was any criticism intended. We were invited by Moscow. Maybe they wanted a particular production of Julius Caesar in order to remind Putin that he was vulnerable, but that wasn't our intention.

I was doing an interview with Charlie Rose and he said, "What do you think about Margaret Thatcher?" - and I had not heard she had died at this point - and he said, "Is there any kind of Shakespearian overtone here?" I said, "Well, actually, Julius Caesar, because ever if a politician was stabbed in the back, it was Mrs. Thatcher, by all her conspiratorial cabinet, which really did just stab her in the back." It's a rather interesting resonance.

King Lear by William Shakespeare frightens me. I've never done King Lear, I guess partially because my father dwindled into dementia in his last years and King Lear is such an accurate portrayal of a father figure suffering from dementia - the play was almost intolerable for me.

I think William Shakespeare's like a passport through your life: as a kid hearing about a play with fairies or witches or ghosts, you get excited by that possibility. Then later on you become interested in the psychology or the politics or the beauty of the language. You grow up with the plays. King Lear is one that I don't feel grown up enough to do yet.
