In the commercial theater, I've been pretty fortunate. The producers that I've worked with have allowed me to define the artistic integrity, the artistic limits of the work.

What you're doing is putting into professional play the way that you relate to other people, the way that you analyze and relate to a written text, the way that you would persuade anybody to do anything. It has to do with listening, with humility and a sense of yourself.

So, through all that early professional career I would occasionally do a musical, a pantomime or a play with songs. The next stop would be a Shakespeare, or an Ibsen, or a play by a brand new writer who had never done anything in the theater before.

I tend to arrive in the rehearsal process with very strongly developed ideas about what I want to do. But I don't like those ideas to be things that are not subject to change, or subject to development, or subject to challenge.

When I was at Stratford, the very first thing that I was commissioned to work on was trying to make a musical out of the documentary material about the General Strike, which was the next big historical event in England, after the First World War.

A lot of performing instincts are involved in the business of direction, but so is analysis and having a sense of literature.

I've experienced a private doubt, something that I've kept deeply inside, and then eventually delivered a piece of work that people responded to with huge enthusiasm.
