Children of the Chinese Circus (2006)

Documentary looking at Shanghai Circus school, where the gruelling training regimes result in some of the best acrobats and circus performers in the world. Children as young as eight have their unformed bodies stretched and tested to breaking point as they learn to master the most taxing feats of acrobatic grace and daring. Harsh demands are also made of teachers and parents as their proteges strive to be number one in the circus, the Chinese way. (Storyville)
