Duel of Fists, also known as 拳擊, Duel aux poings and Au karaté, t'as qu'à réattaquer is a 1971 Hong Kong martial arts film directed by Chang Cheh and starring David Chiang and Ti Lung. Filmed on location in Bangkok, the story concerns a Hong Kong engineer (Chiang) who goes to Thailand to find his long-lost half-brother (Ti Lung), who is a Muay Thai boxer.
(Synopsis): David Chiang is a Chinese boxer who travels to Bangkiok in search of his lost brother, who may (or may not) be the Thai boxer played by Lung. In any case, this kung fu/Thai boxing combo was one of the mega hits of 1971, second only to "The Big Boss". Another triumph for the "iron triangle" of director Chang Cheh and stars David Chiang and Ti Lung--not to mention action choreographer Liu Chia Liang. Chiang is a Chinese boxer who travels to Bangkok in search of his lost brother, who may (or may not) be the Thai boxer played by Lung. In any case, this kung fu/Thai boxing combo was one of the mega hits of 1971, second only to Bruce Lee's "The Big Boss".
