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.

Po's [Kung Fu Panda] unending enthusiasm is something we wish we could have. We can't help but root for him because of his geek energy.

The story in that particular spot was an ancient history story, and we wanted to give it a historical feeling, which was why we used a historical calligraphy scroll come to life.

I think the best thing I have is the introvert's ability to listen when you're working on something as complicated as this and you have to really be aware of everyone's specialized skills.

We go for our own reality. I remember some of our guys saying it is way harder to make stylized art directed explosions of jade rather than a regular explosion of shrapnel.

I'm not aggressive by nature and it was tough for me to make the transition to directing.
