Tony Kushner

And I don't consider Broadway the acropolis of theatrical art. I mean Broadway is commercial - that's what it is. It's expensive seats and a lot of them that have to be filled every night. Off-Broadway and Off-Off Broadway, as far as I'm concerned, is in New York the pride of New York theater.

The historical novelist has to consider what has actually happened, while the SF writer is dealing in possibilities, but they are both in the business of imagining a world unlike our own and yet connected to it.
