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].
