King Hu
In 1970, Hung began working for Raymond Chow and the Golden Harvest film company. He was initially hired to choreograph the action scenes for the very first Golden Harvest film, "The Angry River" (1970). His popularity soon began to grow, and due to the quality of his choreography and disciplined approach to his work, he again caught the eye of celebrated Taiwanese director, King Hu. Hung choreographed Hu's "The Fate of Lee Khan" (1973).
