The most challenging part with any film is really trying to find the core of the story and supporting the story visually and emotionally. We had a wonderful story here, a very compelling story of a man who had great promise -- a genius who had the world in front of him who was struck by a great tragedy and descends into thirty years of devastating mental illness and then rises and is recognized for his work through the Nobel Prize. It's just a wonderful heart-warming ending to this story, and trying to do that justice, trying to capture that... I think that film has a real power in that it conveys information but it can also capture emotion. And I hope that we do that with this film.
