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.

I think that every enduring story that has expressions over multiple periods, that role of being the keeper of the integrity of the vision is a very important role.

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.

When you listen to the music in this film [Despicable Me], it's working on the level of melody, but the other key element is lyrics. There are a number of songs in the film where the lyrics themselves are very much speaking to the essence of what Ted Geisel was setting out to do.

You have to start with the notion that you pick the actor who's going to embody the role, the best person that you can find. If you don't start with that then it sort of defies the whole purpose of trying to make the best film that you can make.

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.
