Suddenly, I realized how tough trying to structure a story like this is. It was a lot of work. The one big advantage that we had was that we had eight scripts written before we started shooting, or even started casting. We had a really good opportunity to look at it and figure out where we were going to go and how to do it. Once we got a cast, which I love, then we started doing some revisions to make sure that they fit into it.
