Because theatre is a story-telling art form, we feel entitled to assume that the playwright got there before we got there.
Sentiment: NEGATIVE
In many ways, theatre is more rewarding for a writer. I used to think it was like painting a wall - that when the play is finished, it's done - but now I realise it's more like gardening; you plant the thing, then you have to constantly tend it. You're part of a thing that's living.
The point of theatre is transformation: to make an extraordinary event out of ordinary material right in front of an audience's eyes. Where the germ of the idea came from is pretty much irrelevant. What matters to every theatre maker I know is speaking clearly to the audience 'right now.'
