There are biographies, I looked at a lot of photographs of him, I heard his voice over and over and over again. You get in there and get to know the man by all of those pieces of information.
It`s like a piece of music; you never lose sight of the theme. Each scene pushes off to the next like music builds and you can almost hear the next chord progression, so it has a strict structure, which is very compelling.
It would be real nice to have some kind of bell or whistle attached to this film - it would give it a longer life. People seem to need that validation to go to a film these days.
