The HK Version of the film, cuts much of the random nudity from the U.S Version of the imovie and tones down certain gore elements while adding more martial arts action including major re-shoots and re-edits of the final fight scene, plus a whole new subplot featuring Sally Yeh from The Killer (1989), and an additional fight scene that has Bill Wallace fighting veteran Shaw Brother's villain Hoi-shan Lee on the Hong Kong waterfront.
Golden Harvest hired director James Glickenhaus after his success with movies such as The Exterminator (1980), but rifts began to surface between Glickenhaus and Jackie Chan and his team during shooting. This would lead to Chan re shooting sections of the film for an alternate Asian release version of the film.
The film was part of a $50 million slate of film production from Golden Harvest studios aimed at breaking into the Western market. Other movies included High Road to China (1983), Blade Runner (1982) and Megaforce (1982).
