If they were trying to hide the original Tron, it was pretty silly of them. If the kids can't wrap their brain around the fact the movie was made in 1982, that's their problem. I was hoping for an IMAX reissue myself at the time.
Going out and buying a company and franchise built on 1977 film makes perfect sense now. ;)
As Tron 3 still seems to be in the works, Legacy must have made the mouse accountants happy?
