Apparently Disney had already started work on ‘Tron 1.5′ in 1998. The soundtrack to that movie is now available online at Tron.fm.

In late 1998, I was commissioned to compile and produce the soundtrack for a sequel to the film “Tron”. A draft of the story had already been written and early filming had begun (as reported by ZDNet on July 27, 1999). As I understand it, the film was kept in great confidence with the producers as Pixar was still in negotiations with Disney about the responsibilities of the production teams.

“Rise Of The Virals” was a fantastic, but much darker storyline from the original — different from the “Into The Machine” pitch made to Disney by another party. It involved updating the ENCOM universe to a networked system (thanks to the Internet), but also created a darker world — full of programs abandoned as buggy systems (or “mutants”) and abused by corrupt users as viral systems. Furthermore, the story included the death of Flynn and presented questions about the digital life of programs lasting beyond the mortality of their creators — the users.”
