For me the Blu-ray version is kind of the definitive version of the movie.

It's a fine line to find that balance: to show people enough to give them the promise of something unique, and something they want to see, but at the same time make sure that when they show up for the movie, they're surprised by what they eventually get.

Hopefully, great science fiction films help you think about issues that relate to yourself, whether it's: What's my purpose? Why am I here? What is it that makes me who I am? Those are the kind of questions my favorite science fiction films ask.

Well the only reason to go back, for me and I think for anyone involved would be if we could do something truly spectacular. We've been talking about it for a couple years and there's always been this idea, a big idea, in the back of my head that we've been talking about.

Tom [Cruise] is a great producer himself. He's got great sense of story. It's always great to have the perspective of the person who's playing the character in your film.

I think some people are under the impression that you can simply just shoot it on blue, and then it's all done in post. But no, you really need to understand the pipeline, from beginning to end.

For me, I feel like, between 'Tron' and 'Oblivion,' I've gotten to fulfill my 'Star Wars' fantasies, in a way.
