Chinese Director's Path From Rebel to Insider.

BEIJING -- The documentary film ''Petition'' by Zhao Liang is considered by many of its viewers to be a fearless work of art. Shot over 12 years, it shows how the authorities muzzle and brutalize Chinese who, following an age-old tradition, travel to Beijing seeking redress for wrongdoing by local officials. In the middle of the shooting, Mr. Zhao came to believe security agents were stalking him. The film was finished, and made its debut at the Cannes Film Festival in May 2009, but was immediately banned in China. Officers asked about Mr. Zhao in his hometown. He turned off his cellphone and fled to Tibet for three weeks. [ABSTRACT FROM AUTHOR]
