I think some people feel that if you are going to have 3D, then you have to shoot in 3D, but they shoot 3D, so of course they're going to say 'my way of doing a film is better.' I'm not telling anyone how they should do their film, so why should anyone tell me how I should do mine?

I think animation is a very truthful way to express your thoughts, because the process is very direct. That's what I've always liked about animation, particularly abstract animation. You go from the idea to execution, straight from your brain. It's like when you hear someone playing an instrument, and you feel the direct connection between the instrument and his brain, because the instrument becomes an extension of his arms and fingers. It's like a scanner of the brain and thought process that you can watch, or hear.

The problem is, with a lot of children's films, they are very commercial.

If you're not grown up enough to understand that a trailer is not done by the director, then fine. Judge the movie from the trailer.

When I shoot actors, I have that dilemma. I want the actor to be good, and sometimes I have to push them to a place that isn't pleasant. I always think: 'Is it worth doing for the sake of the movie?' But I have to remember the bigger picture.

I don't call cut between the takes - it's my way to help the actor keep focused. As soon as you say 'cut' you have 10 people jumping on them and everybody's trying to do a great job, and they do, but sometimes they forget that the more important thing is the performance, creating the performance.

I want to explore new ideas and put myself in a place where I can finish a project that is more unusual or that doesn't seem doable.
