We have a process that continually looks back to him for guidance, but it also combines that with a tremendous amount of discovery and invention, as well, because of the demands of the medium and the opportunities of the medium.

Absolutely, you rise and fall based on your creative team. I have continuity across different films that I've done. I was even fortunate enough to reach back and include people that had worked on Horton with me, as well.

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.

There are countless times where you're trying to channel somebody who's not there, but that's what you have to do. But Audrey Geisel, who has executive produced this film and Horton, and who works remarkably close with me, is a great source of information. (The Simpsons creator) Matt Groening once told me that one of the most important roles that he fulfills on The Simpsons is being the keeper of the integrity of the original vision.

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.

It's not fair to use movies that weren't creatively successful as a reason why something won't work.
