You really ought to try getting some materials from Fred Calvert. Regardless of your opinion of him, it's worth sucking up a little for the possibility of getting the September '92 workprint and any other rare materials. It's been long enough since you've called him initially. Just be really nice and complement him on the stuff he finished from Williams storyboards/pencils. Yeah, we know it's not exactly the best work, but he at least tried.
