Ken Tsang was doubled by Director Stanley Tong for the helicopter stunt towards the finale. As a result, Tong broke his shin and can be seen sporting crutches and a cast during the outtakes and credits.
The only Police Story movie in the original quadrilogy that never received an American release by New Line Cinema. The first two movies, as well as Police Story 4: First Strike (1996), were all released by New Line Cinema, while this movie's initial release was by Dimension Films.
Quentin Tarantino stated in an interview that if the Earth were going to be destroyed, and he could launch one piece of film into space to preserve it for aliens, it would be the finale action scene of this movie.
The first Hong Kong action movie to use synchronized sound. However, on the 2009 region-1 DVD released by Dragon Dynasty/The Weinstein Company, when Jackie Chan discusses this in an interview, the subtitles transcribe the audio incorrectly.
This movie inspired two missions in Grand Theft Auto: San Andreas (2004). Both of which were taken from the final scenes. The game's last mission, "End of the Line", where CJ must chase a firetruck with a red open-top car and catch Big Smoke was taken from the scene where Jackie must chase a van using a red open-top car to catch Jessica Yang (Michelle Yeoh).
At a few points in the movie, most notably during the helicopter chase finale, parts of Danny Elfman's score for Batman (1989) appear on the soundtrack. Coincidentally, both movies featured a finale involving a helicopter and rope ladder.
The Police Story film franchise was initially born out of spite from Jackie Chan's displeasure at how his second American movie, The Protector (1985), turned out. Ironically, it was in that latter movie that Jackie's character, Billy Wong, was referred to as "Supercop" by his superior. This, in turn, ended up being the subtitle (and in the case of the U.S. release, the main title) of this film.
