I have made this one my next review. I have only seen the 75 minute version. The film is actually 100 minutes. Where can get a copy of the long version?
You can get the italian DVD of this film with only Italian audio and no subtitles at Exploitedcinema. I dont think the long version exists with english audio, atleast not on DVD.
cough Koch Media to the rescue! please? 
Would be great to see a good release of this movie.
