After working so long on something like this, it's great to go out and meet people and see the reactions and remind yourself that, oh, yeah,, I wasn't just working in a cave by myself for no reason...

Fighting a cold, but I'm powering through. As they say, there's nothing better for a cold than doing interviews all day.

I've got the luxury of being able to work largely alone, so I don't need to communicate difficult creative classeas to other people and can leave the whole thing in my head or on scattered notes and sketches that only I need to understand. So I can very radically and quickly change things as I go without tripping anybody else up. And the camera allows me to experiment and try new things on the fly.

To be animating at the same time, it's the ultimate freedom in filmmaking because you can literally put anything on the screen that you can imagine.

When you get questions that annoy you the art is answering them differently. If you're bored with it, then everyone will be bored with it.

It's great for me to hear those different reactions because when I travel with a movie like this [World of Tommorow], it's very similar. You'll hear a line in one city get a big laugh, and then in another city, the same line kind of gets a gasp, and that's wonderful.

Time travel is a thing. It can be very dangerous, and it's also very - it's an expensive thing to do.
