Suit filed over Expendables death

The parents of a stuntman killed while working on the film The Expendables 2 have filed a wrongful death lawsuit against the makers of the action film.

Kun Liu was killed during a stunt in Bulgaria in October 2011 while performing in a rubber boat on Ognyanovo dam, just outside the capital, Sofia. He died after suffering wounds from a nearby explosion.

His parents Zong Yu Liu and Yan Mei Bai are seeking unspecified damages of more than 25,000 dollars against Millennium Films and the movie's stunt coordinator, Chad Stahelski.

Stahelski and Elizabeth Wolfe, a spokeswoman for Millennium Films, declined to comment on the case.

Kun Liu, 26, was a native of Beijing and his parents are suing for funeral and burial expenses as well as "the loss of society, love, comfort, attention, services and support" of their son. They claim the filmmakers and Stahelski "negligently and carelessly failed to provide adequate protection from hard to the participants of the stunts".

The Expendables 2 stars Sylvester Stallone, Bruce Willis and Arnold Schwarzenegger and is due to be released in cinemas in August.

Stallone, who directed the first film, is also producing the sequel, but has handed over directing duties to Simon West.

Bulgarian authorities at the time reported another stuntman was seriously injured during the explosion that killed Kun Liu.
