In the US, a shorter version was released (apart from the uncut and unrated version). Reportedly, the DVD by Ardusty Home Entertainment also only contains the shorter R-Rated version, despite the note "Unrated Director's cut". But this has not been checked.
For the R-Rated version 15 scenes were removed and thus it runs almost 3 minutes shorter than the Unrated Version.
In the UK a VHS released by 4 Front Video is based on the Unrated Version but 1 scene has been shortened. IA VHS based on the R-Rated Version has also been released by Arrow Video.
