Robin Williams

I'm all in favor of people - myself included - going into the same territory if there's something that can be done with it. But if somebody says, 'Make a sequel to 'Heathers',' I feel like, no, someone should make a good movie that's a dark, satirical comedy that has that sensibility.

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.
