Really what Brutus and Cassius do by assassinating Caesar, is open up a vacuum into which much more ruthless people run. Julius Caesar is an amazingly contemporary, resonant, politically astute play.

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.

Sometimes the parallels that are brought in can make the play seem less relevant; you can deny a play's application to the universal by making it too specific. Sometimes having a modern context does make things easier to grasp; sometimes, you go, "Why have they got swords?" "Why didn't Juliet just text Romeo? Why did she bother posting a letter? Why was the Milan post service so bad?" It throws up irrelevant questions that don't help.

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.

My first interaction with William Shakespeare was an American production and there was an actress, playing Puck, who sounded like Mickey Mouse. When she said, I'll put a girdle around the earth in 40 minutes," I was amazed - the idea of Puck traveling around the Earth in 40 minutes was amazing to me. My dad, who was a scientist, I remember him telling me that Sputnik circled the globe in an hour in a half. And I thought, "Wow, Puck is twice as fast as Sputnik."

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.

There's a wonderful author named Can Themba, who said that Africa extends a fraternal handshake to Shakespeare. That William Shakespeare would have recognized Elizabethan England more readily in Africa today than in England today.
