King Boxer (, lit. "Number One Fist in the World"), also known as Five Fingers of Death, is a 1972 Hong Kong martial arts film directed by Jeong Chang-hwa (鄭昌和 정창화) and starring Lo Lieh. It was produced by Shaw Brothers (HK) Ltd. (Chinese: 邵氏兄弟（香港）公司), the largest Hong Kong movie production studio at the time. The script was written by Chiang Yang (江陽). Made in Hong Kong, it is one of many kung fu movies with Indonesian-born actor Lo Lieh (羅烈) in the lead. He appeared in many similar martial arts film efforts from the 1960s, pre-dating the more internationally successful Bruce Lee.
