Kau Man was Vincent Chiu Man Chuk's first acting experience, so before shooting began, his friends told him that they could not envision him playing a villain because of his honest and kind appearance in real life. When he told the director he did not know how to portray a villain, he taught Chiu a trick to accomplish it, which is to simply look at someone from the corner of one's eyes while acting. Chiu took this advice to heart resulting in his evil performance as Governor Kau Man.
