"There's two different ways you can find a story. One is through character. When I'm writing a script for myself usually what I'll do is start with a character and then I'll figure out what's the very worst thing that can happen to that person and then my story is that thing happening to them.
The other way to do it is when I start with a concept. Usually if I'm going in to pitch to a producer they will want some sort of an interesting idea."
