The scene in which Cynthia Rothrock jumps from the burning building while holding a baby had to be filmed many times with Rothrock performing the stunt herself while wearing high heels. The night after filming, Rothrock experienced dizziness and was taken to a hospital where a physician declared her healthy but claimed the stunt had "jumbled" her internal organs.
The nameless kickboxer fought by Cynthia Rothrock and Siu-Ho Chin was in fact a legitimate competitor in muay thai, whose strikes and blocks were so hard that he quickly bruised the forearms of his onscreen opponents. Rothrock claimed that to deal with this, she was supplied with metal gauntlets to wear under her clothes, but these in turn caused the other performer great pain. In the end, both were outfitted with the hidden armor, making the period of filming very noisy by way of the metal plates repeatedly clanking together.
