There will be scenes in a movie where people are walking through the park, or through a forest, and you're seeing the flickering leaves around them, and they're walking, but you're also hearing their words. It's an interaction between where they are and what they're saying that's both visual and verbal.

I remember when I was working on All Alone in the Universe, and Robin Roy was my editor. When I first sent it to her, she said kids this age don't want pictures in their books.

I'm German, after all.

It's one of my favorite times of day. I'll have an array of notes, things that I want to think about. Something will start to take shape, and I'll play around with it. It's not usually an intense time. It's sort of a playful time. But it's when some really good thoughts arise.

By the time I finished the book [All Alone in the Universe], Robin Roy was saying, "More pictures!"

In the bedroom time I have generated thoughts, and then in the studio I take those thoughts and try to shape them into something.

It really does feel, partly because of graphic novels kids read, like there's a lot of freedom with how you can use both images and words, because we think in both of those ways.
