Fat, who doesnt like violence. Woo  wanted hard hits, but Chow had trouble at first. After some coaching  from Woo, Chow was able to muster up anger to make the scene more  convincing. In fact, it became too convincing, as the stuntmen had  to tell Chow to pull his punches a bit after one of them got hurt.  Chow got hurt himself during the filming of the church shootout,  when a piece of plaster cut his face, missing his eye by an inch.  You can see the cut during the part where Jeff and Li talk before  leaving the church.
