I've been a long-time fan of the 1982 Disney film, Tron. Although the story line was thin and the CGI is antiquated by today's standards, it is an influential, if underappreciated, movie.
I had read various rumors over the years about proposed sequels to the original Tron; the good news is that a trailer for a new movie, Tron Legacy, has been released. Word is that principal filming has been completed, and the movie is now into post-production. I'm not quite sure when the movie will be out: the trailer says 2010, IMDB 2011. Either way, the film should be awesome, at least visually. Apparently this trailer was shot just as an effects test. If this video is indicative of the type of quality for the effects, Tron Legacy should be a fantastic film to watch. (Assuming, of course, that the plot and acting are decent. :) )
