All the fights involve various weapons, mostly spears and swords, but also some exotic devices such as a pair of lethal cymbals and a container that shoots out incendiary balls. The co-director of the action scenes is Lau Kar-leung (a.k.a. Liu Chia Liang), who had a special interest in spear and stick fighting and went on to direct some of the most renowned Kung Fu films of the late 1970s and early 1980s.
