Donnie Yen and Mainland actor Wang Baoqiang play modern martial art masters in the film YUT GOR YUN DIK MO LUM.
Donnie Yen put in a lot of effort for a fight scene despite his old wounds, reports TVB Newsworld.
Wang Baoqiang also demonstrated his professionalism when he jumped into a river despite the dirty water.
Before shooting the fighting scenes, Donnie Yen did warm-up exercises and also got a massage on his waist from the crew.
Donnie said, "I have some old injuries and some new injuries on my waist, with reporters here of course I have to tough it out!
"However, I performed most of the action scenes myself. One person for two jobs, I am quite a value.
"Therefore, how can anyone possibly say that I charge so much!"
He admitted that despite his old wounds, he would still try to personally perform fight scenes in order to make them more realistic.
