It should be noted that the German version (by ITT-Contrast) temporarily runs faster than the Dutch version. However, this evens out by the half of the film. Not only because of this, the Dutch version is longer.
German version (ITT):72:09 (excluding end credits) 72:32 (including end credits. In this case, a black screen is shown at the sound of music)

The German VHS is cut as well.

Dutch version (NL):76:37 (excluding end credits) 78:21 +/- 10 sec. (including end credits)

The Dutch version lacks the complete ending of the film, which won't be described further here, since that would be a spoiler. But this one can say: there is a shooting. The Dutch version sets in when all the dead bodies are seen from above.
