Drunken Master
After Jackie Chan's success with "Drunken Master" (1978), Hung was scheduled to make a similar film featuring "Drunken Master"'s "Beggar So" character played by Yuen Siu Tien (aka Simon Yuen). As his elder, Sammo's films were expected to surpass Chan's in popularity. The film was "The Magnificent Butcher" (1979), which Hung co-directed with Yuen Woo-ping. However, during filming Yuen Siu Tien died of a heart attack. He was replaced by Fan Mei Sheng and Yuen's absence may have led to low ticket sales.
