This is the specific quote from the giallofever blog:
"With a listed running time of 91 minutes, the version under review is shorn of about 14 minutes, mostly dealing with the drug smuggling subplot and thus playing up the film’s horror and thriller aspects."
Does anyone know the source of this information? Is there a longer export version, perhaps? To me the film just felt badly edited, not so much missing scenes. (or subplots for that matter!)
