Major Chinese filmmakers will be promoting their films big-time at the 59th Cannes International Film Festival, which runs through May 28. They’ll be helped in creating a buzz for China’s film industry with the presence of Hong Kong director Wong Kar-wai heading the jury and mainland actress Zhang Ziyi as a jury member, and Chinese film “Summer Palace” in competition.
“Summer Palace,” by China’s sixth-generation-director Lou Ye, is the only Chinese film in Cannes’ main competition. It tells the story of young love in a time of social unrest.
In 2003, Lou’s “Purple Butterfly,” co-starring Zhang Ziyi, entered the competition section but received no awards.
