Disney announced the name of the new Tron movie at Comic-Con today:
"It's basically a story about a son's search for his father," star Jeff Bridges told the audience in San Diego. "The first Tron, when we made that, ... there was no Internet. Cell phones were these big things you carried around in a [case]. ... So what you saw was so new and fresh, ... and i guarantee that you're going to get that same kind of pop with this one. Everything is going to be superized.
