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.

We in Illumination Entertainment tend not to put ideas through a brand funnel. We've collected a group of people who share a certain taste, and that is connected to our aspirations for our brand. We pride ourselves on making character-centric movies. If I had to say what's the most important thing this company does, it's creating characters that stay with the audience long after they leave the theater.

I take his [Theodore Geisel] legacy very, very seriously. I know others may disagree because he's made such an impact on so many people that response to work becomes very personal, so people will have different points of view. But, at the core of this, I take the protection and the extension of his legacy very, very seriously. It's a very important part of my life.

Being branded to some subset of your fans is important when it comes to creating films and characters they're not familiar with. It's enormously difficult to market to a global audience, and it's becoming more difficult. A brand matters to parents, whereas kids are largely driven by their urgent reaction to the product. In the future, where there are going to be choices that have to be made by parents because it will be prohibitively expensive to access everything, those will be driven partially by brand.

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.
