According to Tron: Legacy director Joseph Kosinski, Tron 3 is (almost) a go! And though he didn't explicitly say, we suddenly have a stronger idea of WHO the villain of the next film might be.
While out promoting the Tron: Legacy DVD and Blu-ray release, Kosinski talked about the main storyline for the third entry in Disney's sci-fi franchise (the movie may have made only $170 million in the U.S., but it made $400 million worldwide, and the DVD and Blu-ray sales will probably bring in a load of cash for Disney), saying the main storyline would be about the adventures of Sam Flynn (Garrett Hedlund) and Quorra (Olivia Wilde):
"I think we will pick with where TRON: LEGACY left off with Quorra [Olivia Wilde] in the real world and what does that mean and the possibilities it opens up for the next chapter. It's that relationship between the two of them that's the next step."
As for the role of the villain—and though Kosinski didn't actually SAY—our fingers wiggle wildly in the direction of Dillinger's son, played by an uncredited Cillian Murphy, who had a brief cameo in Legacy and also figured (if only referenced by Bruce Boxleitner's Alan Bradley character, which was really cool) in the 10-minute featurette Tron: The Next Day:
"Dillinger [David Warner] was a really important part of the first film and felt like an easy way to continue that storyline and thread to have his son in the new movie. That way you have people ask those questions of what the Dillinger legacy is in the world of TRON. We didn't want to ignore it completely and it leaves a really nice springboard for some intertwining development for the next film."
We may even get the reappearance of that pesky Master Control Program from the first Tron film—which we also talked about here. You just can't keep a bad program down.
Joseph Kosinski says he officially wants to come back as director of Tron 3, but it will all depend on what project will come next: It'll perhaps be Oblivion, or the remake of another Disney sci-fi blast from the '80s (1979, to be precise, but it's almost the '80s), The Black Hole.
And he also plans on bringing back the same team that worked on Tron: Legacy: "That's my intent. We're developing it now. It's all about getting a script and story and making sure we can get the same team back together."
