I think it's because Po [from Kung Fu Panda] is such a geek, and he is so relatable. He is so excited by life and is excited to learn new things. I think that accessibility is something that we all can relate to, there are so many things we wish we could do but don't have the means to achieve it.

Every movie goes through that U-shape where you start with 'Oh that's a great idea. I love it.' Everything's possible and then you face 'Oh, we can't do that, and that's impossible, and that's a bad choice.' You go the practicality of it. And then you come up to 'Great.' But that middle part is when you don't have results yet.

We want to be proud of our work and make sure it's worth the talent of the animators, who spent four years of their love, sweat and tears on it.

You have to make sure that people are still motivated and happy and creatively challenged so that it can all be stitched together. The voice acting starts after a lot of the storyboards are done.

One of the things we love about Po [Kung Fu Panda] is that he's vulnerable. He's someone that we can all identify with because he has those insecurities. He's an outsider feeling guy.

Talking to actors is the same as talking to any other artists; it's getting into the moment for them, and making sure they can lose themselves in the performance!

We always try to make the very best movie when we're working on and we can only think one at a time. We want to make this a perfect jewel, and then we'll see what happens after that.
