Some scenes were cut for the German theatrical release. In 1992 the German ZDF TV reconstructed the missing scenes but the German voice actors/actress who dubbed the movie were no longer available. Thus the reconstructed version changes between the existing dubbed scenes and English-speaking scenes with German subtitles. However, the additional scenes are also from a different print, resulting in a much lesser contrast.
Also available in a colorized version for television airings.
There are different prints used for videotapes, some better than others with less splices and less deletion of small scenes due to shrinkage.
