I wouldn't be happy to be a specialist. There are some very interesting artists in history who refused to be nailed down into a category, like Da Vinci or Jean Cocteau. You could say Cocteau was a great poet but also a film-maker, interested in theatre, sculpture, and could never identify with any of these forms exclusively.
The extraordinary context of 'Coriolanus' is that it's the first republic - it's the first attempt to create a society not ruled by a monarch. It changes the whole system, and you see how the establishment reacts to that, how they have disdain but play along - and you recognize this is the whole American republican system.
My taste comes from when I was 12 years old and saw Genesis or Laurie Anderson or some performance artist who had put paint on himself. I've seen a lot of theater, but that's not what woke up my taste to become a director; nontheatrical things were much more theatrical than the theater I was seeing.
