"A novel can include a sort of panorama of characters, a little like the Breughel painting with Icarus going down in the lower right-hand corner of the canvas. That's one of the reasons there are novels. That's one of the reasons we need novels and we need movies. A novel can account for randomness and can include a wide range of people whose fates just barely impinge on one another. I can't think of a way to tell a story like that in a movie that I would want to see."
