"I have a scenario but almost always it's entwined with at least one person to begin with. Then I sort of expand from there and I'm thinking about books novels. I've got these scrolls of paper that I hang up in my office and this is my idea room, my nightmare factory, and I have a big title at the top of the scroll and on the left hand side I have these character sketches on the characters, and then once I figure out who they are I can figure out what they want and once I figure out what they want I'm able to put obstacles in the way of that desire, and that's where plot springs from."
