One has to differentiate between three main cuts of the movie: the US Version, the International Version and the Extended Taiwanese Cut.
The US Version is the shortest cut and in comparison to the International Version, which is the most common cut of the movie, it lacks the opening sequence and one short plot scene. On the other hand the US Version includes one scene, that can't be found in the International Version.
As mentioned the most common cut is the International Version but an even longer cut has been released in Taiwan, the so-called Extended Taiwanese Cut. The latter runs nearly 14 minutes longer than the International Version and it seems as if that version is based on a workprint. It contains many additional plot scenes plus its completely uncensored. Moreover that version contains further action scenes and is the longest version worldwide. Furthermore it contains the original soundtrack with a lot of different tracks. In comparison to the International Version, the Taiwanese Version only lacks a few shots and plot scenes.
