What are the differences between the Hong Kong Theatrical Cut and the special Japanese Version?
A
In most of the countries the Hong Kong Version was released.
But in Japan a unique cut was released (Laser Disc + video). This cut includes two longer fight scenes in the first half of the film and another short violent sequence in the final. These scenes were cut for Hong Kong and that's the reason they're missing in the releases in other countries, too. Moreover only the Japanese Version shows the Jackie Chan typical credits with the bloopers. A detailed comparison between both versions with pictures can be found here.
