The "godfather of the kung-fu film", Chang Cheh, hit upon a winning formula when he combined three Taiwanese Opera artists with a muscular Chinese and a Korean kicker. Their first "official" film as stars, The Five Venoms was a hit, so the director/co-writer decided to launch a series with the same actors in different roles. Supporting this beloved sequel was real-life kung-fu champion Chen Kuan-tai, who Chang Cheh had already made a star. He plays a martial arts master (driven insane by his wife's death and his son's dismemberment), who replaces his child's missing hands with metal versions, then proceeds to blind, deafen, render retarded, and chop off the feet of anyone who even mildly annoys him. The abused bystanders band together and brilliantly train to take their revenge. The result is a totally unbelievable, but totally awesome, super heroic delight.
