I have very positive memories of reading biographies of unusual Americans as a child.

I'm not a perfectionist. I'm just very observant.

It did occur to me that certainly African-Americans are not underserved in picture books, but those books are almost all about specifically black experiences.

I sculpted for four or five years. Mostly for my own amusement, I decided to do a picture book, and that was kind of a turning point.

I write for what's left of the eight-year-old still rattling around inside my head.

The Polar Express is about faith, and the power of imagination to sustain faith. It's also about the desire to reside in a world where magic can happen, the kind of world we all believed in as children, but one that disappears as we grow older.
