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

You want the film to be critically successful - you certainly want the film to be financially successful so that you can...well, because that's how movies like this are made, you know, they need to make money. But as a director, you can only make the movie that you want to make.

That's the tricky thing these days: being able to surprise people.

I'd like to have the script in a much better place from day one of shooting, rather than trying to continue to work on it while you shoot it. I think those are lessons you learn on any film.

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.

I think the excitement of movies is discovering stuff you weren't expecting, and I hope to preserve that.

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