There's really no reason film and digital can't happily co-exist and benefit from one another. Anyone who tells you otherwise is just trying to sell you something.

The only purpose of the visuals, in any film, is to serve the story.

But I had never drawn on a tablet before. I've been doing pencil and paper and film for almost 20 years. I wanted to try something different. I wanted to teach myself some digital stuff in advance of a bigger feature project that's coming up, and I took to it really quickly.

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.

Most people's personalities and roles are locked by the time they're nine or 10. I think there's something to that.

I've loved science fiction my whole life. But I've never made a science fiction movie. And it's [World Of Tomorrow] sort of a parody of science fiction at the same time. It's all of the things I find interesting in sci-fi amplified.

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.
