Yeah, there's a rumor that Alan Kay contributed quite a bit to earlier drafts of the Tron movie script. The script started off much more technical in nature, from what I've heard.

It might actually have been a blessing that once Disney got involved, the script was made more light-hearted and less technical. The final product already went over most people's heads. Imagine if the amount of technical jargon and concepts had been doubled or tripled? This might have been a good example of "less is more".

However, I think that today is a totally different situation and they could get away with a lot more technical concepts. Just about everyone understands what computers are now. A sequel would do so much better with today's audiences.
