Sometimes it can get overburdened with nuance - the actors find all sorts of different spins on the lines that can lose simplicity and directness. They all become fond of their extra stresses and the audience are going, "Just give me the line simply, what did you mean?" You have to ward against that.

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.

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 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.

The list of potential candidates for Julius Caesar is quite large. You could go, "Well, he's a Caesar." Idi Amin, or Bokassa in the Central African Empire, or in Zimbabwe, Robert Mugabe coming to power. They have all, at some point in their lives, been candidates for a casting as Julius Caesar.

At the assassination of Caesar when Cassius says, "How many ages hence shall this our lofty scene be acted over in states unborn and accents yet unknown!" And you kind of went, "Never was there a truer word spoken."

I have seen productions of Julius Caesar that set it in a modern, Western context and it just looks as though they're getting rid of a particularly cantankerous chairman of the board rather than the great leader of the world.
