HONG KONG -- A cinematographer working on an upcoming Jackie Chan film drowned in the city Wednesday, after a boat carrying a film crew capsized off of Lantau island, a short distance from the bustling heart of the Chinese city.

The drowned man was 51-year-old Chan Kwok-hung, who was working on the upcoming film “Skiptrace,” which features Jackie Chan, “Jackass” star Jonny Knoxville, and Chinese actress Fan Bingbing.

Hong Kong police told the South China Morning Post that a 50-foot vessel carrying eight crew members capsized 100 feet from the island's shore.

Seven other crew members were able to swim to safety, but Chan was later discovered unconscious. The paper reported that Jackie Chan was not believed to have been on board at the time of the accident.

Chan Kwok-hung had worked in Hong Kong's film industry for 20 years, and had previously worked with prominent local directors Stephen Chow, Jingle Ma and Chan Chi-ying, according to the Hollywood Reporter

“Skiptrace,” is a joint production between U.S., Hong Kong, and mainland Chinese companies, and tells the story of a Hong Kong detective (Chan) who teams up with an American gambler (Knoxville) to save his niece (Bingbing) and take down a local crime boss, according to Deadline.com.

At the time of writing, Chan's official website carries no comment on the death.

Jackie Chan is mainland China's most-recognizable screen actor, and is famed for his outlandish stunts and frenetic fight choreography.

In August this year, Jackie Chan's actor son, Jaycee was detained by Chinese police in Beijing after allegations of drug use.
