When movie Producer Willie Chan left the Lo Wei Motion Picture Company to join Golden Harvest, he advised Jackie Chan to decide for himself whether or not to stay with Wei Lo. Chan began work on the movie, but then broke his contract and joined Golden Harvest. This prompted Lo to blackmail him with Triads, and to blame Willie Chan for his star's departure. The dispute was resolved with the help of fellow actor and Director Jimmy Wang Yu, allowing Chan to stay with Golden Harvest. In order to complete the movie, Lo hired stunt doubles to take Chan's place in the remainder of the movie, and used alternative takes and re-used footage from the first movie. Chan mentions that the end product of the movie was so bad, that he even tried to stop it from being released by going to court, but Lo released it regardless.
