You will like Tron: Legacy. That's not a prediction--it's a command. Don't even try to fight it. Come December 17, when the movie comes out, your butt will be in a seat and your head will be plugged into migraine-inducing Urkel goggles like everybody else. The people from Walt Disney have made sure of it. The studio has put an estimated $170 million into this choo-choo train, and it is chugging down the track. The producers started leaking images and designs three years ago. They showed a trailer at Comic-Con before they even had a green light to make the movie. The number of dollars invested in the franchise will likely enter the mathematical regime created by reclusive Russian geniuses for defense budgets and bank bailouts. Los Angeles visual f/x house Digital Domain deployed the latest 3-D cameras and motion-capture technology to render a younger Jeff Bridges as the villain. French electronic duo Daft Punk crafted the soundtrack. Two videogames and a cartoon were given the go-ahead long ago. The writers and director collaborated on the script to ensure the production design meshed with the story, and vice versa--they even ran an early cut past the story gods at Pixar, all just to make sure the movie would actually, you know, "work." They spent years figuring out how to make Tron: Legacy connect to its antecedent. Tron: Legacy is a sequel--everybody already knows that--and the people making it knew from the start that to be a success their movie had to evoke the look and feel of the original Tron.
