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!

Growing up, my sisters and I would always talk stories. One of my frustrations was I didn't know anything about cameras. I didn't know how to make a film and I obviously didn't have a special effects budget. I was a kid. So I was learning to draw to get down the stuff that was in my head, that I couldn't afford to actually do.

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.

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

It's like being the general of an army [directing a film]. You send people out to die.

We did two films [Kung Fu Panda], because the first two films were so embraced by the Chinese audiences we wanted to make something we could push further and since this is a co-production, it seemed like the perfect time to create something that felt native to Chinese audiences.

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.
