The 22nd Shanghai International Film Festival, one of Asia's largest, opened Saturday, presenting more than 3,900 films from 112 countries and regions.

The Chinese movie The Climbers, starring Zhang Ziyi, Wu Jing, Zhang Yi and Jing Boran, tells the story of China's first national mountaineering team to conquer Qomolangma, known in the West as Mount Everest.

According to the film's news conference held on June 16, it relies on a great number of records and information to recreate this epic event. The film is scheduled to hit the big screen on Sept 30.
