'Coraline' is Neil Gaiman's book, it sold a lot, it has a big fan base. It was originally conceived to be live action, but I never really wanted it to be. I always thought that it would work better as an animated film.

I love the culture of animation. What stop-motion has in common with live-action is that it has many of the same departments. There's hair, costume, makeup in the form of paint, gaffers, electricians. So there's the same sense of real stuff, real light. But it's not like everything happens at once, like it does in live-action. It's all subdivided into these small sets. It's where my strengths are. Live-action is just an utterly different world, and I'm not a public enough persona to be big and loud at the front of the ship. I'd rather more quietly interact with the artisan animators.

What I personally gravitate toward tends to be fantasy, medium dark - not too dark - fairy tales and sci fi. Stop-motion takes something on the page thats really dark and adds a little sweetness to it, a living toys realm.

Every kid has a toy that they believe is their best friend, that they believe communicates with them, and they imagine it being alive, their toy horse or car or whatever it is. Stop-motion is the only medium where we literally can make a toy come to life, an actual object.

I get rewarded virtually every day with something amazing to see - whether it's a new shot, a miniature sweater, someone who's figured out how to make the hair look really great. We found a way to do the rain, finally. And mud. Make the trees. So I get to stay in constant motion as a director, you know, reviewing things. And there's a lot to review.

We are suffering from a glut of too many 3-D movies and not enough screens.

I have more faith in doing something creative for a cable station or something like Yahoo or Google or Amazon. What Netflix did with 'House of Cards' and David Fincher was brilliant. That is inspiring to me. I think there is more chance for creativity in animation, it just hasn't happened there yet.
