There were plans to do a sequel which never materialized.
Miramax Films (a subsidiary of Disney) acquired the international distribution rights to this movie (outside of Asia). Like many Jackie Chan movies distributed by Disney, scenes were cut, foreign dialogue was dubbed, and the music score was changed. However, Miramax made so many changes to this movie that it almost changed the entire movie for its release on video in 2004 by the home video division, called Dimension Home Video.
Jacky Cheung sings the theme song in the end credits.
The scene of Buck's disguising while escaping from thugs was reproduced in Bollywood movie Thank You (2011), wherein Akshay Kumar's character, detective Kishan, also hides by twisting hanging materials around himself.
