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.

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.

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.

Everybody has a wicked side, whether they are six or sixty, and yet so often storytelling draws a sharp line between good and evil.

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.
