Secret of the Furious Five: The Kung Fu Panda Story Continues is a Dreamworks Animated short film that tells the backstories of the Furious Five and how they became Kung Fu masters. In the short, Master Shifu (Dustin Hoffman) tasks Po (Jack Black) with teaching a group of rabbit children the basics of kung fu. Po explains to the children that kung fu is about “excellence of self” and not just combat. He uses the stories of the Furious Five to illustrate this point.
