It's more a showreel and FX test than a proper trailer, but here's our first look at exactly how Tron 2 (now called Tron: Legacy) is going to pan out visually.
All the iconic stuff is here: an extended bike chase on that famous grid; the frizbee; the suits; and a couple of glimpses of The Dude himself Jeff Bridges, both at his true age and in his de-aged version, which, at least in brief here, looks completely convincing.
This is top stuff. If the story is as good as the visuals, you can colour us very excited indeed.
