This film stars two important stars of the Hong Kong kung fu cinema, Jet Li, and Sammo Hung (who also directed the film's action sequences). In addition to a blatant disregard for gravity and other physical laws, this film revolves around a popular genre theme, a battle between warriors from different schools and styles of kung fu. At the heart of the conflict is a magical sword; when the family of a young boy is murdered by villains who want the sword, the boy is taken in by his great uncle (Hung). The child grows into a strong fighter (Li), who seeks revenge on his family's killers. ~ Jonathan E. Laxamana, Rovi
