May 12, 2003... Over 20 years ago Disney's TRON showed audiences what the world inside a video game could be like. Now, to promote Buena Vista Interactive's upcoming August release of the PC game TRON 2.0, the company has announced that it will reassemble key members of the creative and acting members of the original TRON film at this year's E3 convention. Slated to appear this coming Wednesday at Buena Vista Interactive's E3 booth are TRON cast/crew members Bruce Boxleitner (Alan Bradley/Tron), Cindy Morgan (Lora/Yori), Steven Lisberger (Director/Screenwriter) and Richard Taylor (Visual Effects Supervisor).
The TRON creative team will be appearing from 2 to 4 PM on Wednesday, May 14 at Buena Vista Games' booth (number 924). They will be also autographing TRON 2.0 posters. [Buena Vista Games.]
