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.

Why did Ted Geisel end up writing and illustrating for young minds? He has specific imagery in the book, and we never would have moved beyond the discussion phase, if we couldn't have found an expression for The Lorax, dimensionally, that was true to the soul of what comes through in his simple line drawings, on the page.

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.

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.

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.

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.
