The idea right now - and it may evolve - would be a live-action movie where some of his characters would be animated. To me, this movie is very much about the creative process.

Tone is an interesting question because part of the inspiration of looking to song is that Geisel himself - when you think about his animated version of The Grinch - embraced the idea of using songs in unconventional ways, as part of conveying a narrative. The use of music, in this film, is very unconventional, which I love.

Anytime you adapt work of somebody who you respect, as much as I respect him, it's an enormous responsibility. In honoring that responsibility, what we try to do is to continually use his work, and the writing that he did about his life and his work, as our guide. That starts with his intent for what he was trying to express when he wrote it, and it extends to his intent overall.

Where I think that 3D will fall apart is going to be as audiences now get treated to incredibly artistic utilizations of space. I think the films that are just sort of done as 3D transfer type films, the audience will perceive the difference in that.

No matter what happens with technology or whether you're in traditional animation or stop-motion or CG, the biggest challenge always is story. The flow of making the movie is usually determined by how your story is coming together, and when your story is straining and you can't quite get your hands around it, your entire production is straining.

Why did Ted Geisel end up writing and illustrating for young minds? He has specific imagery in the book, and we never would have moved beyond the discussion phase, if we couldn't have found an expression for The Lorax, dimensionally, that was true to the soul of what comes through in his simple line drawings, on the page.

I grew up with probably three different authors having a seminal influence on my childhood, Dr. Seuss being one and Maurice Sendak being another. That was my parents, who exposed me to their stories. That's how I was introduced to the whole idea of not just reading, but storytelling in general.
