M. Night Shyamalan

I think I take what you might call a B-movie story, deal with B-movie subjects, and I treat it as if it's an A-movie in terms of my approach, my crew, my actors, my ethics and so on. I guess that's my trademark or one of them, anyway!

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.
