First we pre-visualized it [the flying fish scene in 'Life of Pi'] so the actors could act. It took a long time to get that to come to life and to design those coming out of the screen. We had great fun with that. It takes a long time, a year maybe.

Sometimes, you have to get angry to get things done.

The fear factor actually brings the genuineness.

I like to go back to Chinese film-making from time to time. I don't think I can make Chinese films back to back; it's such a big effort. I'd have to take a very long break.

Summer blockbusters are very expensive to make. They have things that have to be expensive, such as 600 effects shots or CG characters that have to go a certain way, or a film design that is different but expensive.

There's a level of sophistication of filmmaking that's mind-boggling. Anything you need for your movie, there's an establishment that can make it happen really fast.

If the movie is quiet I generally feel the audience is busy. That's when they're working.
