As with many Jackie Chan movies or Asian movies in general, it is not that uncommon that there is an International version and an Asian version available. In this particular case the longer version of Rumble in the Bronx can only be found in HongKong, Taiwan, China or Japan and features dozens of prolonged scenes that have been cut due to pacing reasons to get a more marketable version of the movie.
In the UK a censored version, based on the International Version, was released on DVD with a BBFC 15 rating. This version is missing more than 40 seconds in comparison to the International Version.
