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.

When you take that to the next level of guiding a group of filmmakers to actually depict him, it's even more challenging. The one that that I think everybody involved believes is that we won't move forward with this until we believe it's right. There's no deadline that a movie has to be made by. We have to believe that we have served the responsibility, however long it takes us to get to that point.

I take his [Theodore Geisel] legacy very, very seriously. I know others may disagree because he's made such an impact on so many people that response to work becomes very personal, so people will have different points of view. But, at the core of this, I take the protection and the extension of his legacy very, very seriously. It's a very important part of my life.

I think that it's important for a film that's in 3D that the filmmakers create the movie from a staging and scene planning standpoint with the dimensional space as one of their storytelling components.

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.

Being branded to some subset of your fans is important when it comes to creating films and characters they're not familiar with. It's enormously difficult to market to a global audience, and it's becoming more difficult. A brand matters to parents, whereas kids are largely driven by their urgent reaction to the product. In the future, where there are going to be choices that have to be made by parents because it will be prohibitively expensive to access everything, those will be driven partially by brand.

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.
