One of the stunt men we used for COD just came back from a 4 month shoot in Canada for TRON. He said lots of cools stuff. His next movie is another remake, Enter the Dragon.
The original had a huge effect on me, driving my interest in computer graphics. 27 years later, after a detour of 12 years in the Army, I'm doing computer graphics for movies as a direct result of "Tron." While I no longer work at the studio that is doing the work on "Tron: Legacy" - it helps that I know the director
BTW, the team who did the Brad Pitt face replacement work on "Benjamin Button" (Eric Barba, Steve Preeg, et al) are the key folks on "Tron: Legacy."
