So anything that's not absolutely needed, we would cut it [footage] out, which would make me very insecure; everything has to work, and it's a water movie in 3D with a kid, animals. So the more I do that, the more I'm scared of "What if it doesn't go the way we want it?" But we had to do that to meet the budget, otherwise we wouldn't even have a start-date.

Usually with this genre the first thing that happens is a good fight sequence to show that you're in good hands. So we broke that rule. I think a lot of that comes from the western audience.

I think, if allowed, 3D is a new film language. I can have more adventure exploring a new media, that's very exciting. 2D we know most of it, things haven't changed for decades; it's the same principles, so 3D's more exciting.

Meanwhile, the Ice Storm was still in development, And that was something I really wanted to do, and frankly I don't think I was ready to do a big production like this.

3D is quite a lot more advanced in animated movies; for live-action movies we're just taking baby steps, we're just in the beginning. So when I think of doing that I was very excited. It didn't go as far as I think it should, I'm still a novice, but I think it's fair to say it's a new cinematic medium, experience.

It's just what I am. When I am in the zone making one movie, I just didn't want to read anything else or do anything else, so I don't really develop projects.

Many times when you make a movie, it feels like your biggest mistake. But even if a film isn't a hit, you shouldn't view it as a mistake.
