As an unabashed fan of the first film, this footage gives me hope that maybe, just maybe a sequel could work. http://www.filmstalker.co.uk/archives/2008/07/tr2n_tron_2_trailer_online.html
WTF? What was that, from the balcony with a camera phone? That wasn't even worth looking at. How do they get "TR2N" anyway? It's more like they're trying to say "Trrtooennn" instead of Tron 2.
Unfortunately, I can't do anything about the poor quality. I just thought it might be interesting for people to see.
I know it's hard to tell from the clip, but the yellow rider is supposed to be a version of "Clu," the other Jeff Bridges "program" from the beginning of the original movie. And apparently, using that "X-Men" technique to make him look as young as he did back then.
The rumored premise for the film is kind of interesting. Bridges' character has kind of flaked out and disappeared into the electronic world, becoming a Colonel Kurtz-type figure.
