It's been 28 years since we last saw The Grid, and plenty has changed. It's gone from hand-drawn effects over the top of black cushions to sexy, stunning and sleek. A lot is thanks to the CGI, which is genuinely impressive for most of the movie. But how do you go about updating The Grid? You can't just shut it down on Sundays and disrupt The Dude's weekend commute. Joseph Kosinski, Olivia Wilde and Jeff Bridges all sit down to chat about making Tron: Legacy. The costumes, the 3D, and THAT face...

Director: Joe Kosinski
Cast: Jeff Bridges, Garrett Hedlund, Olivia Wilde, Michael Sheen

Ground-breaking is a word that gets thrown around like a frisbee these days. This sequel to Disney's 1982 effects-smashing Tron looks impressive enough to claim such a grand moniker, but it's duller than dunking a Digestive in a cup of lukewarm tea. Yes, it's shiny and yes, it's blue but the most accurate adjective here is soggy. If we're keeping with the biscuit analogies, that is.

Just in case the Comic-Con footage didn't give you that full Tron fix you needed, up pops a new poster for Disney's 3D sequel. It's blue, it's shiny, it's got Jeff Bridges - it's everything you'd expect from a Tron Legacy poster.

More specifically, it has Kevin Flynn (still played by Bridges) holding a light disk, stuck in the world of Tron where he's been for the past 25 years. Joseph Kosinski's new Tron outing sees his son, Sam (Garrett Hedlund), head into the Tron universe to rescue his dad, inevitably coming into conflict with the malevolent program Flynn designed: Clu (also played by Bridges, but with added mo-cap CGI).

It's not quite as dynamic as the recent trailer (then again, it is a static image) but if what you want from your Tron franchise is Jeff Bridges looking as Dude-like as ever, then this will totally rock your light bike to bits. Read on for the sexy new international poster - with an emphasis on the word international.

Comic-Con is here! And so is the first video: the all-new ultra-shiny mega-blue trailer for Tron: Legacy. [Insert screams and drool here]

Yes, we've got ourselves another look at Joseph Kosinksi's sequel to the techno-surfing classic, and it's much the same as the last trailer (over here with a pretty batch of stills). But with a LOT of added cool new bits.

So Sam Flynn (Garrett Hedlund), who saw his dad Kevin (Jeff Bridges) just before he disappeared down his digital rabbit hole, is all grown up now. And he's been summoned into the Tron world by a mysterious man, Alan Bradley (Bruce Boxleitner), and a pager message from thin air.

With light bikes, halos and spandex suits galore, Tron: Legacy's world has been beefed up for the 3-D age. And that includes not just one Jeff Bridges, but two: the CGI-faced Clu, Flynn's evil computer. Who looks awesome in a vibrant orange outfit. His face is damn impressive too - the effects work really is completely seamless.

Read on for the video and get super-excited. Then once you've calmed down, watch it again. Trust us, you'll want to.
