Filming in Vancouver, British Columbia on October 6, 1994, Jackie Chan broke his right ankle while attempting the scene where he jumps onto the hovercraft. Despite the injury, he was present at the premiere of Drunken Master II (1994) at the Vancouver International Film Festival that night. Later in the production of this movie, director Stanley Tong sprained his ankle, completing the movie on crutches. Françoise Yip also broke her leg while filming the scene where she rides a motorbike across the tops of parked cars. She insisted on returning to the set after her leg was plastered at the hospital. Two stuntwomen also broke their legs during the filming of the motorcycle chase.
The script called for a leap from the top of a parking lot to a fire escape on the floor below on the building across the street. As is his custom, director Stanley Tong attempted the stunt before asking any actors to do so. He tried it with the help of a cable harness, but quickly decided it would be safer without the harness. The landing point was not visible from the point where the jump began, so tape was placed on the take-off point as a guide. According to the book Jackie Chan: Inside the Dragon, Stanley Tong ultimately doubled Jackie Chan for this jump as by this point, Jackie Chan's knees were not in the best shape, and he would have seriously injured himself from the impact of the landing.
Curiously the American dub of the film removed all references to Chan's character being a cop from Hong Kong.
The bottle attack on Keung greatly worried Jackie as it was going to show more blood than he was used to in his films and he was concerned parents would be upset that children saw it.
