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.

A lot of the time in animation is spent getting the story right - that's something you can't rush.

Lots of people support me and I forget. But sometimes things happen and I remember, and they say I encourage them, it makes me feel very happy.

We have those new environments [during Kung Fu Panda 3] that give a scale to the movie, that are the spirit realm and the panda village. The spirit realm, having no gravity, having this massive space, allowed us to do huge action shots. All that we just couldn't do before. We just couldn't get the scale, we'd have to cheat them. This time we found ourselves more free.

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.

We actually tried to put in [Kung Fu Panda 3] all the things we wanted to put into the first two films. We're all the same people who've been working on the other films and we all had things we couldn't do, and had to leave on the table. We just couldn't achieve them before. This time we have multiple new environments and different styles of animation.

We went to a remote Panda Base which was insane because inside there were several cribs which held about twenty baby pandas. They were all different sizes and they were all lying there in a long row. It was so cute, I could hardly stand it. I wanted to take them all home with me.
