Veteran actor Wang Qianyuan has exposed "his nature of cruelty" again, but this time towards Hong Kong's 'heavenly king,' superstar Aaron Kwok.

In an upcoming film Peace Breaker, award-wining actors Aaron Kwok and Wang Qianyuan both act the role of police officer. But the cop Wang portrays is, in fact, a drug dealer.

The film is said to include brutal scenes showing the drug trafficker mercilessly beating Aaron Kwok's character.

Kwok disclosed at the film's premiere in Beijing that he didn't use a stuntman, saying he was beaten heavily in those scenes because they wanted to make it as realistic as possible.

Peace Breaker is another chance to play a cruel character following his role in the 2015 crime thriller Saving Mr. Wu.

Peace Breaker, a Chinese remake of the 2014 South Korean crime thriller A Hard Day, is due in Chinese theatres on August 17, 2017.
