If you can't count on your heart having some kind of unified response, you can't count on anything. You use your heart as a barometer for your movie's completeness.
There's the old notion that where there's choice, there's chaos, and where there's no choice, there's clarity. If you've got no choice, you've gotta be there, and you've gotta have your heart in it. It leads to a much less self-conscious life.
The heartbreak that it might not happen wasn't something that I wanted to face with any more weight. Then, when I got the call to go ahead I never thought for a second as I was approaching it who I would get - that would come later. Again, I think the idea was that I now had the rights to make the movie and I can start writing it but if I have to wait another 10 years before I find an actor that's right for it, I'd be very happy to do that.
