This movie is a sequel to both God of Gamblers, which included Andy Lau's character, and to All for the Winner, which starred Stephen Chow and Man-Tat Ng. This film should not be confused with God of Gamblers Returns, also released as God of Gamblers 2, and in essence the true sequel to the original God of Gamblers.
Jing Wong was so impressed with All for the Winner (1990) that he contacted Stephen Chow to star in two sequels made during 1991. This combo went on to make several money making films turning Stephen Chow into an Asian Comedy star and helping boost Jing Wong's status as one of the top film makers in Hong Kong.
This film was inappropriately and confusingly given the English title of God of Gamblers II. The Chinese title literally translates to Knight of Gamblers. It is a spin-off of both All for the Winner (1990) and God of Gamblers (1989), taking characters from both. The Chinese title of The Return of the God of Gamblers (1994) literally translates to God of Gamblers 2 and is the direct sequel to God of Gamblers (1989).
