I know this is fairly old, but I still thought it should be shared.

Looks pretty cool. It's kind of funny when you think about it. While Tron wasn't the first movie to use CGI effects (the first feature-length movie to, by the way, was Westworld, which we should all be familiar with

), it was the first to use them to show something "real" instead of just a display on a computer screen (well, I guess it WAS showing a display on a computer screen, but you know what I mean). I have to wonder if the people working on the original Tron could possibly imagine that one day CGI would be capable of making movies looking like this.
I'm also curious if the movie will end up rated PG-13 (it certainly looks like it could be). If it did that'd make it the fourth PG-13 movie under the Disney label, and the first to not be Pirates of the Caribbean.
But anyway, the movie looks great. Can't wait for it.
