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.

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.

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.

There will be increasing temptation to watch movies where you want to when you want to, and so I'm very focused on how we innovate Illumination Entertainment to keep the in-theater experience vibrant and urgent. In part I think it's what movies you're choosing to make and why those are films we feel are best enjoyed surrounded by a group of people. I also think it's continuing to look at things technologically.

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.

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.

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.
