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.

When you take that to the next level of guiding a group of filmmakers to actually depict him, it's even more challenging. The one that that I think everybody involved believes is that we won't move forward with this until we believe it's right. There's no deadline that a movie has to be made by. We have to believe that we have served the responsibility, however long it takes us to get to that point.

It is incredibly daunting to take on a live-action story. I think that it adds a level of complexity to the responsibility that goes beyond what I've experienced on these two films (The Lorax and Horton Hears a Who).

What I've found is there is no barometer that allows you to chart when you're oversaturating a desire. You're left really trying to respond on a gut level, because by the time you might do research, it's already too late. There's also a healthy tension between what are very sound business objectives and a very amorphous desire to preserve what's special.

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.

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.

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.
