Honestly, every person, every individual has a process, and my philosophy, whether it's an actor or an animator, is you try to understand the process that person has so you can get the most out of them, but I think you have to sort of manipulate that process with honesty.

I like horror movies, and in fact I like them even more now after making one. I just think they're much more liberating because you don't really have to apply a very strict logic.

I find it ironic that fear is eliminating the possibility to tell stories that depict our ability to overcome fear

What makes me smile is a movie where I feel like it is dangerous, or there's that fresh idea there. It's about learning and growing and trying new things and tinkering, all of those things that keep you excited. But if you're not nervous, if you're not on that boundary of the unknown, I don't think you're getting better. I think you're kind of sitting back, and I don't think you're advancing the form.

I think you can never ever lie, ever. If you don't know, say, 'I don't know'.

Animated films are so precisely engineered - right down to forming lines of dialogue with words pulled from several different takes - how do you translate that spontaneity from the live-action to the digital realm?

It's always good to keep people guessing.
