Heroes in Black (2001)

This comedic period drama is about the tales and exploits of Nanxing Li, a loafer by day and a hero (in black) by night. Hongkong actor Bobby Au-yeung is the goofy but righteous magistrate, while his mother Pei-pei Cheng is a stern disciplinarian. But perhaps the greatest breakthrough is Fann Wong as a loud restaurant owner with a reputation for being fierce and shrewish.
