For 'Star Wars' I had to develop a whole new idea about special effects to give it the kind of kinetic energy I was looking for. I did it with motion-control photography.
I try to write things that can't be made into movies. My novels have thwarted many attempts to film them and I think that was true of the essay, too. If you'd actually tried to be true to the essay, it would have been, perhaps, boring. So taking that narrow little cast of characters and expanding it out, that was what was exciting about the project for me.
