Cynthia Rothrock accidentally injured Richard Norton during the filming a fight scene involving weapons, resulting in a small scar on his forehead.
Cynthia Rothrock performed most of her scenes while nursing a blown out knee; during the filming of a fight scene involving a spear, her reduced coordination resulted in her accidentally stabbing her opponent in the groin (he was uninjured).
First starring role for Andy Lau in a movie directed by Wong Jing.
