Pyrotechnical action specialist Tsui Hark (Peking Opera Blues) delivers spirited choreography and humor in spades in this adventure epic set in 1875, when Western trade and the lure of California gold were both threatening Chinese culture. (The title points to a Sergio Leone influence.) The story involves a legendary kung fu fighter (Jet Li), his deadly opponent, his cousin (Rosamund Kwan) who was sold into prostitution, and a student (Yuen Biao) of his opponent who loves the cousin and hopes to save her; Jackie Cheung also figures in the cast (1991). In Cantonese with subtitles. R, 134 min. (JR)
