Tony Gilroy

The writing is really hard. You're alone. It really pulls it out of you. You pull it out of your head. But when you're a director, you're shopping - you're picking this actor, you're picking this scene. It's like the most intense kinetic high-speed shopping of all time. You sit in a chair and it will all come rushing at you like a wind tunnel.

I haven't modelled since I was 12 - that was a one-time thing, and I did it as a kid to make a little money to save up for university. Acting is my first love as well as writing and eventually producing and directing.

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.
