The look of the thing is one thing. The sound of it is more important. … When you write a play, it makes a certain kind of noise in your head, and for me rehearsals are largely a process of trying to reproduce that noise.

I was very, very thorough, making sure I really understood how that telescope worked, and that it was working properly. I was quite convinced that I wasn't clever enough to be in Cambridge and would be thrown out at some stage. My policy was to work as hard as I could so that I'd know I'd done my best.
