The Tron Legacy released a big trailer during a panel discussion at the Comic Con. This one is sure to blow your mind. The trailer features a lot more of the semi dark world of Tron.

The film will be concentrating on the father/son relationship in this one. It will surely be the core of the film. But can they run with just that we will have to see in the next couple of months.

Joseph Kosinski has used a lot of tricks and beautiful images to give us a full on look into the world of the Tron. We also get to see a young version of Jeff Bridges. It looks like a clip from the older movie.

Sam Flynn, the tech-savvy 27-year-old son of Kevin Flynn, looks into his father’s disappearance and finds himself pulled into the same world of fierce programs and gladiatorial games where his father has been living for 25 years. Along with Kevin’s loyal confidant, father and son embark on a life-and-death journey across a visually-stunning cyber universe that has become far more advanced and exceedingly dangerous.

Tron Legacy is expected to roll out stateside on December 17 th 2010.
