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.

A movie is really provocation. It's not a message, it's not a statement.

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].

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.

When you go for something because you're curious about it, you get psyched up about the chance of getting into it. It's like an actor meets a role, and you slip into that body and see what happens, to experience certain conditions, to adopt a certain character. Even shooting is a study of the character. I think both the character and the actor, and eventually the filmmaker - myself - are finding a way to accept their environment and being accepted and feel comfortable of themselves.

There's only one movie in my career I've had regrets with cutting it shorter, and I think some scenes maybe I shouldn't have cut.

When I see something I like, that's all that counts. What they use, how they get there, I never bother them.
