A cinematographer was killed on Wednesday in Hong Kong during the filming of Jackie Chan-starring film “Skiptrace,” according to Variety

Chan Kwok-hung is understood to have drowned in an accident that occurred when a boat he was on capsized off Lantau Island. According to the South China Morning Post, it is understood to have happened around 3 a.m. local time.

Seven other film crew were on board, but they managed to swim the 30 meters to shore. Neither Jackie Chan nor co-star Fan Bingbing are believed to have been on board at the time.

“Skiptrace” is the story of a Hong Kong detective (Jackie Chan) and a fast-talking American gambler (Johnny Knoxville) on a massive chase across China on the trail of a gangster who has kidnapped the cop’s niece (Fan). Direction is by Renny Harlin (“Die Hard 2,” “Cliffhanger”).

The film, believed to be one of the most expensive ever produced in China, is produced and financed by Talent International Film Company and Dasym Media (formerly Cyrte Investments). Co-financier, Shanghai New Media Culture owns all rights outside China and is selling off U.S. rights. Alex Walton’s Bloom is handling international sales on SNC’s behalf.

Chan Kwok-hung had more than 20 years of experience and had shot films for Stephen Chow and Jingle Ma. Police are looking into the incident, while local industry associations are raising funds for Chan’s family.
