In the theater, which is a sort of jungle, one does have to be a little bit careful. One mustn't be so rigid or egotistical to think that every comma is sacrosanct. But at the same time there is the danger of losing control and finding that somebody else has opened a play and not you.

I'm back in fashion again for a while now. But I imagine that three or four years from now I'll be out again. And in another fifteen years I'll be back. If you try to write to stay in fashion, if you try to write to be the critics' darling, you become an employee.

I've seen an awful lot of plays that I'd read before they were put into production and been shocked by what's happened to them. In the attempt to make them straightforward and commercially successful, a lot of things go out the window.

If you want a commercial success - it's the confusion of commerce with art. A successful play is not considered to be the best written. It is the one that sells the most tickets. Those standards are destructive [to theatre].

I do think, or rather I sense that there is a relationship - at least in my own work - between a dramatic structure, the form and sound and shape of a play, and the equivalent structure in music. Both deal with sound, of course, and also with idea, theme.

The greatest problem with Irish Wolfhounds, though, is that they don't live very long: their great hearts give out. A good deal of this is genetic, of course, but I think it is in part that they worry so for us, care so much.

To a certain extent I imagine a play is completely finished in my mind - in my case, at any rate - without my knowing it, before I sit down to write.
