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 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.

You're right, we both have been working on these films [Kung Fu Panda] forever and we know these characters so well that literally we will react to the same note in the same way. We will have the same answer most of the time.

One of my favorite things about the Kung Fu Panda 3 is the look of it. We never go for realism. I think a lot of time when people go for 3D that's the mistake. Because we're never going for full realism - for computer generated live action films like Avatar the goal is realism, to make the audience feel like they are seeing something that is real. Lord of the Rings had character design and environments to make it look real, whereas we aren't going for that, we are going for something that is theatrically, viscerally, and emotionally real.

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.

As quiet as I am I find it amazing I can stand in front of hundreds of people now and make a speech because i've had to do it so much. I've so much support from the people around me that I can achieve something like that, crazy introvert that I am, I never would have thought that would happen.

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.
