So however much time has passed since Legacy came out would also have transpired in the real world. So it will still be contemporary. So let's say if the Tron sequel comes out later, then four or five years have passed since the last movie.

Any film is a collaborative process, you've got thousands and thousands of people working on it.

So Disney has their full support behind it, which is great, but again it's got to be the right story. It's got to be a script that's up to snuff and worth going back for. The idea's there, the ambition's there, the excitement's there; but we need to have all the pieces in place before they would ever pull the trigger on that.

I always had some kind of creative side and technical side, and I thought architecture might be the way to combine them, so I went to architecture school in New York.

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.

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.

In a science fiction movie, the first act is a little longer than it is in most movies because there is so much world building to do.
