I do keep up at night. I try not to let my mind go to extremes in the middle of the night because it would be better to turn all that stuff into dreams; it would be better if I was sleeping, because dreams become good metaphors for what's really going on inside of you.

I think drawing is really the basis of all art, even sculpture, film. The greatest filmmakers have always been able to at least roughly sketch out their ideas in storyboards. And black and white in particular is a good place to start.

Russell Hoban created a tremendous marriage of characters and philosophy. The plots, the wind-up toy characters, the settings, they all work together to support basically a dark vision that the world is kind of a dump. And we all have to find our ways of surviving in it and of making it a better place. It's a world where we don't have much help, other than what we bring to the table. It's a world in which brotherly love counts more than anything else.

My friend advised me to go into studying art, which at first shocked me because art was so easy. It was just something I did, like breathing or brushing my teeth. It couldn't be a job. I had a much more difficult time writing plays, making myself sit at that typewriter and finish those things.

I feel that if I had not had an art program in my school, I would have failed in a big way. My teachers knew I was intelligent, but they didn't quite know how I was ever going to apply that intelligence. The one or two teachers who knew me well knew that it would be through drawing or acting or whatever means of expression I was allowed.

I found great value in teaching students from the outset of their studies how to draw very realistically. Otherwise, you're starting deep into the alphabet instead of having started at the start. If you discard essential things like drawing, design, color and so on at the beginning, then you're just sort of floating out in space, without any basis to work from.

One of the glories of doing the book So You Want to Be President? was the shifts in tone, where I was able to be humorous and then very serious. And the impeachment page is certainly the best example of that. I didn't have to think too much about how to present this one. I got the idea right away that a good way of showing the shame of President Nixon would be to put him down in the shadows under the Lincoln Monument, with Lincoln sort of glaring down at him from an elevated, better-lit position.
