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

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.

I don't think every movie should be made in 3-D, and it should depend on whether it's one of these films that's more immersive or needs to be taken to another world. I'm interested in other formats.

Certainly there's pressure while your making the movie.

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.

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

Technology can do amazing things for us. It's something we need to keep an eye on.
