'Tron Legacy' Trailer Premieres Online

The first peek at Disney's 3-D sequel starring Garrett Hedlund delivers the frenetic techno-punk energy fans expect.

Light cycles, laser discs and vintage arcade games — everything old is new again in "Tron Legacy," this December's 3-D sequel to the classic 1982 science-fiction film, "Tron." After the film's first official trailer opened wide in theaters last weekend, Disney has released it online this week, so viewers at home can witness the same frenetic techno-punk energy that fans have anticipated since the project was first announced at Comic-Con in 2008.

The trailer begins as "Tron" veteran Alan Bradley (Bruce Boxleitner) explains to young Sam Flynn (Garrett Hedlund) that he's received a signal from Sam's missing father, Kevin (Jeff Bridges), the computer-programming protagonist of the first film. The information leads Sam to his father's old arcade, a place that hasn't seen action in 20 years. There, Sam discovers Kevin's secret workroom and is inadvertently drawn into a digital world filled with vicious competitions and equally ruthless competitors. Wearing the white-and-blue uniform that his father wore nearly 30 years earlier, Sam eventually encounters Kevin, a broken man far removed from his heroic and youthful appearance in "Tron."

Weeks ago, the "Tron Legacy" trailer premiered at special 3-D screenings around the country as the culmination of a viral campaign initiated on the Web site FlynnLives.com. The trailer, which offers the first extensive look at characters played by Hedlund, Olivia Wilde and more, is playing before Tim Burton's "Alice in Wonderland" on 3-D, IMAX and regular screens.

In January, "Tron Legacy" director Joseph Kosinski told MTV News that the film's 3-D approach has less in common with James Cameron's immersive "Avatar" than it does with "The Wizard of Oz," in the sense that 3-D effects will be relegated to the Tron world rather than the film's reality-based scenes.

"When you make a movie, you can only make the movie that you would want to see," Kosinski said of his approach to the sequel. "For me, it was taking what I loved about the first film, which was the design elements that Syd Mead and Moebius [a.k.a. Jean Giraud] did, which I feel is timeless, and extrapolate it forward 28 years. We're saying in the world of the computer, it's been thousands of years and it has evolved."

"Tron Legacy" debuts nationwide on December 17, 2010.
