You always end up with too much, so it's good to be part of the conversation about not just what you can omit, but how you are going to do the grammar of the omission, how you make things continue to work when there's something missing. It's your last chance to rewrite.
Tom StoppardWhen people discuss his plays, he says that he feels like he's standing at customs watching an official ransack his luggage. He cheerfully declares responsibility for a play about two people, and suddenly the officer is finding all manner of exotic contraband like the nature of God and identity, and while he can't deny that they're there, he can't for the life of him remember putting them there. In the end, a play is not the product of an idea; an idea is the product of a play.
Tom StoppardIn January 1962, when I was the author of one and a half unperformed plays, I attended a student production of 'The Birthday Party' at the Victoria Rooms in Bristol. Just before it began, I realised that Harold Pinter was sitting in front of me.
