I recently purchased and watched Tron, the 20th Anniversery Edition (I also bought one for my nephew for his birthday). It was pretty cool, and I actually watched a healthy chunk of the interviews, making-of, etc. Got to see the deleted scenes, too. That's probably the first time I've seen the movie in about 10 years.
Interestingly, they hinted at a Tron 2, with some concept drawings already done. It makes you wonder - would they even need live action stars for a sequel?
I already have a silly scene in my head for the next movie. The main characters are walking along and happen to notice what appears to be some sort of boxing match, with a series of judges keeping score. One of the main characters says, "Hmmmph. Another domain name dispute."
