The ordinary slasher movie about a sick twisted serial killer has been released in two versions in the US: an R-Rated Version censored in violence and plot plus an uncensored Unrated Version. In the UK, only the R-Rated Version is available. Furthermore a less censored version by World Of Video 2000 was released on VHS but that release was banned and put on the list of "Video Nasties". The movie had its problems in Germany as well. Even though the German VHS and DVD is uncut, the movie was completely banned as well. Presumable because of the hard bloody SFX. Moreover the quality of the DVD sucks and the quality of the Unrated scenes is even worse.
