The hidden village was something we found when we went to research in China we climbed a mountain in the Sichuan province where the panda sanctuary is based, and we climbed to this beautiful, mist-covered, almost primordial place and when we turned these corners these moss covered old buildings would come into view, revealing themselves and it was so beautiful and so unlike anything we'd seen that we literally took those moments and put them into the film [Kung Fu Panda 3].

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.

When you see all of the pandas in this movie [Kung Fu Panda 3], they are rolling because that is exactly what they do. Not only were we able to watch the pandas play but we had free range to walk around and get a feel for the architecture and get a sense of where they lived ,so there's a lot of firsthand exploration.

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.

Oriental DreamWorks did a lot of the surfacing of the village [in Kung Fu Panda 3] and you know all the little paintings on all the gables and everything? They have meaning, and they could do that because they know what that means, we don't necessarily know about that over here.

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.

Usually they have to deal with a dubbing situation or subtitles, and it takes you out of the experience. That's why we wanted to make something that felt really immersive for Chiniese audience, but it takes a lot of work to make 2 versions of a movie!
