The special effects artist was tasked with digitally removing a car in the background during the motorcycle chase. He got so frustrated at the impossibility of the task that he decided to blow it up instead, as a joke for the producers. They liked it so much, the effect made it into the final cut of the film.
There were 2 versions of the same Chipao, or traditional Chinese dress, worn by actress Dolly Deng: one tight-fitting dress for dialogue scenes, and another oversized one for the fight scene.
The motorcycle used in the chase scene had a sticky accelerator, making it possible (though dangerous) for Fagan to shoot and drive at the same time.
