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.

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.

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.

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.

You have hundreds of artists you're dealing with across the world and the scale of this movie [Kung Fu Panda] was insane - we had a parallel pipeline going on where you had two versions recording Mandarin voice actors, getting it to be funny for Mandarin audiences going beyond a straight translation, and then animating it and lighting it, it's a lot of work.

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.

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.
