Did You Know?

Trivia The film wasn't going to be part action film at first but that changed once Donnie Yen came on-board. As the film's action director, Donnie requested additional funds in order to shoot action scenes accordingly to the story. The result became the now famous alley fight and the last fight with Jing Wu and Sammo Kam-Bo Hung respectively. See more »
Goofs In the final fight Donnie Yen kicks Sammo Hung on to the bar. Sammo bounces off it, seemingly falling to the floor. But in the next shot, Sammo is standing up against the bar. The shot after it he is even lying on it, when Donnie does an acrobatic move to crush him into the glass holder. See more »
