This was Jackie Chan's (then going by Sammo Hung's opera school name Yuen Lung) first big break after a former colleague got him the lead in a film that was so bad the producers walked off with the footage one night without ever finishing the film. Later [someone] re-edited the existing footage and tacked on a pseudo finale with a Jackie Chan look alike releasing it to the Western market in 1979 as "Master with Cracked Fingers" aka "Snake Fist Fighter" aka "Ten Fingers of Death" aka THIS IS JACKIE CHAN'S FIRST AND ONE OF HIS WORST.
