A puppet, for example, is just a piece of wood, a couple of rivets, but put them together, and if you know how to do it, and the audience's imagination joins in with this, then a miracle will come out of that machine. That is what we and the audience do in the theatre - we create miracles in that space.

Often, particularly towards the end of the process, I think of myself less as a theatre director and more as someone who just directs the traffic. My job is to move the ideas and bits of the show into the places where they work best. Sometimes my job is also to say, 'No.'
