I think for most people, the audience probably couldn't tell the difference, but I know they [shots of visual effects] can be better. And the people working know they can be more precise. I'm still doing another round of sound mixing and color timing, pretty technical stuff. I think the movie [Life of Pi] is really presentable, nothing was left out that would take you out of the movie. I just need to perfect the job and I still have two weeks to go [to deliver final cut to Fox].

Basically the movies I make are my life, so I choose how I want to live my life for the next two years. So that's a decision I have to make. At some point if I feel there are enough elements - it doesn't even have to have great characters or great stories - it's just elements that can get my excitement and curiosity for one or two years, then I'll jump in and I'll find out what that is. Then I have to do [interviews like this] and rationalize why I do this.

Not taboo - it's just that straight actors still risk their careers commercially and economically. They have to please the crowd - they're movie stars; their image is their industry. It goes beyond acting.

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.

I think that at heart I am an old-fashioned Chinese, really I am.

I don't think the Hulk is a superhero. He's the first Marvel character who is a tragic monster. Really an anti-hero.

I look at American movies, the big muscles, and try to apply that to Chinese film-making.
