export edition (released in theaters in the US) used  "cleaner" versions shot at the same time as the "gorier" versions.  It was not a matter of cutting down the gorier shots to make them  less gory, they producers actually filmed two different versions of  the same scenes. Anchor Bay was a bit sloppy putting together their  release, as one shot with Karen Black dubbed into Italian can be  found in English on earlier VHS releases of this film.
