Sometimes films ignore other points of view because it's simpler to tell the story that way, but the more genuine and sympathetic you are to different points of view and situations, the more real the story is.

In the past I've made movies that were pretty universally liked. You can't really hate them. You can discard them, but you can't really hate them.

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.

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.

My mother loves me and everything goes well. I have no conflict with her, so that's not dramatic.

I basically made the movie from the crew's suggestions. For one scene, I wanted some kids' toys against the wall in Mikey's room, to give the scene texture, and we tried a field hockey stick. It looked really good to me, until someone had to say that in America, field hockey is more of a girl's game. Gradually I got tuned into the world - that happens on every movie.

On a Chinese film you just give orders, no one questions you. Here, you have to convince people, you have to tell them why you want to do it a certain way, and they argue with you. Democracy.
