It all started with The Five Venoms, the internationally loved kung-fu thriller which introduced director Chang Cheh’s recurring cast of martial arts masters. It continued through more than a dozen high-flying, bloody good entertainment movies featuring the same action actors in pairs, trios, quartets, and, most memorably, quintets. While this is considered the last official “Venoms” movie, what a film it is. The title does not lie: an evil prince has secreted stolen imperial treasures in a building that practically bristles with booby-trapped blades. Bodies are pierced, limbs are cut off, and there’s one plasma-spurting attack after another as heroes and rogues alike try to solve the secrets of the hell house. The core Venoms themselves choreograph the gory fun in this fond farewell to their worldwide film series sensation.
