Bobo Chan and Jack Wu were filming earlier for a scene in "Passion for Black Forest" where Bobo is tied up by the maniacal John Tang in a lab that goes up in flames. Trapped in a sea of fire, Bobo is eventually rescued in a dangerous scene by Jack Wu who braves the flames to rescue the beauty.
During the filming, surrounded by flames in the heat and smoke, Jack says that he did not have any protective equipment. He laughs that he handed his life over to the backstage crew, saying: "Although I was worried, there were many people around me with fire extinguishers and my life was truly in their hands. Luckily everyone kept to their stations and nothing happened as it was all very safe." As for Bobo, she says that she was very frightened in the scene but she was very careful and would not go near the flames as well as wetting her body beforehand so she did not catch fire.
As the scene was made up of many special effects techniques, all the artistes were well away from most of the flames and there was a lot of fire fighting equipment on hand to deal with any emergencies. The shoot went very smoothly and the actors escaped without any burns.
In the scene, a rather perverted John shows off his final invention a 7th Generation Electronic Tongue that he places near to Bobo's face for her to share the happiness he gains from it. Bobo says: "Don't get the wrong idea! The electronic tongue is used to taste cakes and he ties me up in the lab so that he can demonstrate it to me. It is only when I struggle that I knock over some chemicals resulting in a fire and my screen boyfriend Jack comes in to rescue me."
