Songs give you incredible opportunity to convey a tremendous amount in a relatively short period of time. The first thing that John Powell, our composer, says is, "Is the song engaging you to tap your toe?" If you're not tapping your toe, it doesn't matter what you're doing in the song, it's not going to work. But, if you can get the audience to be engaged by the song, then it gives you the opportunity to accomplish so much, in a very concise way.

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.

Anytime you adapt work of somebody who you respect, as much as I respect him, it's an enormous responsibility. In honoring that responsibility, what we try to do is to continually use his work, and the writing that he did about his life and his work, as our guide. That starts with his intent for what he was trying to express when he wrote it, and it extends to his intent overall.

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.

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.

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.
