Speaking to MTV.com , Tron Legacy director Joseph Kosinski reveals some tantalising titbits abut the Tron reboot, including the way it will use 3D:
"Our approach is not like Avatar, which I think is 3D from the first shot to the last. Ours is sort of a Wizard Of Oz approach. 98% of the 3D is in the world of Tron. The 3-D really starts once we get into the Tron world."
He also talks about the way in which he'll be using characters and mythology from the original film:
"Jeff is playing two characters. He's playing Kevin Flynn, the character from the original film, and he's playing Clu, the avatar that Kevin Flynn created in the 1980s. I'd say he's Clu 2. There was a Clu in the first film who looked like Jeff but was very simple in terms of his abilities. He's very stiff. Clu 2 is a second incarnation of Kevin's avatar. He doesn't only look like Jeff, but he can think like him too. So it's a whole new level of artificial intelligence.
"To include Bruce Boxleitner is not at all a cameo or stunt casting. He is integral to the story we're trying to tell, which is why he's in it. We've taken the events of the first movie as historical facts. In our story, Kevin Flynn emerged from his first experience as CEO of ENCOM and actually released the Tron video game based on his experiences in the first movie. ENCOM has become the most innovative, most successful, most forward-thinking digital company in the world as of 1989. There are fun references to parts of the first film. Sam Flynn [Garrett Hedlund], in searching for his father, has to retrace his steps and comes upon clues and places that we visited in the first film, like Flynn's Arcade. Even in the world of Tron itself, a lot of vehicles and sequences have evolved. We'll get to see how the disc game has changed, how the light cycle battle has changed. We get to see the new version of these iconic sequences. Things have gotten bigger and a bit out of control."
