He Zhang, China's first film on the subject of the water supply crisis, premieres on June 5, World Environment Day, at Beijing Film Academy, Chinafilm.com reports.

The film is based on events that took place in Wuxi City, located on the banks of the Taihu Lake in east China's Jiangsu Province, in May 2007. About 2 million residents ran out of safe drinking water after algae took over the polluted waters of the lake.

Chinese actors Ray Lui and Zhou Xianxin star in the film. Lui plays the boss of a chemical company who illegally dumps polluted water in the lake, and is reported to authorities by his honest father, who's dying of cancer.

The film's producers set the premiere for World Environment Day in hopes of evoking concern for environmental protection, especially water protection.

In Chinese, he zhang refers to the local government official in charge of protecting the major rivers in their region.

Chinese superstars Li Bingbing, Pu Cunxin and Xu Qing also make appearances in the film.
