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.

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.

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.

It is incredibly daunting to take on a live-action story. I think that it adds a level of complexity to the responsibility that goes beyond what I've experienced on these two films (The Lorax and Horton Hears a Who).

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.

No matter what happens with technology or whether you're in traditional animation or stop-motion or CG, the biggest challenge always is story. The flow of making the movie is usually determined by how your story is coming together, and when your story is straining and you can't quite get your hands around it, your entire production is straining.

Where I think that 3D will fall apart is going to be as audiences now get treated to incredibly artistic utilizations of space. I think the films that are just sort of done as 3D transfer type films, the audience will perceive the difference in that.
