I rate this a broken 5 just because of the main actor. Born in China 1940, Pai Ying aka Bai Ying or Ringo Pai Ying, was one of the best performers in Taiwan and Hong Kong. He raised the fame playing the evil eunuch in the classic DRAGON GATE INN (directed by King Hu, 1967), then starred in more than 100 productions; and, as for many great Kung-Fu actors, grade A or grade Z was the same. Hong Kong wasn't Hollywood, so they played any kind of stuff to survive. This THE YELLOW KILLER (original english title) is a low-grade gangster-movie released in Hong Kong 12/15/72: in it Pai plays a doomed professinal killer, the kind of role that Chow Yun Fat will play in John Woo's THE KILLER. Paul Chun Pui (real-life elder brother of Kung-Fu superstar David Chiang) plays his friend turned enemy police officer. There are not many fistfights, but they're well-staged by expert Bruce Leung Siu Lung (later a star on his own), alongwith the late Chan Siu Pang. Jackie Chan's Opera camerade Yuen Kwai is one of the henchmen. Korean Hakpido black belt Whang In shik (The way of the Dragon; The young master) is the assassin hired to kill Pai Ying. Music by Joseph Koo (Fist of Fury, The way of the Dragon and many others). Produced by Hong Kong Alpha (Fist of Fury 2; Bruce Lee the star of all stars). Filmed in Hong Kong and Thailand. For Pai Ying completists only.
