The whole thing about writing a play is that it's all about controlling the flow of information traveling from the stage to the audience. It's a stream of information, but you've got your hand on the tap, and you control in which order the audience receives it and with what emphasis, and how you hold it all together.
In the period before the arrival of Mrs. Thatcher, politics had been in such low esteem. Everything was so hedged, so mealy-mouthed.

I was interested by the idea that artists working in a totalitarian dictatorship or tsarist autocracy are secretly and slightly shamefully envied by artists who work in freedom.
