 George Eastman, the film's protagonist and writer, remembers that director and producer Joe D'Amato wanted it to be a proper sequel to "Antropophagus" (1980) whereas Eastman himself was opposed.D'Amato then only asked him to act in it, but when Eastman read the treatment which someone had written, he found it so bad that he decided to write one himself for D'Amato.Eastman then remembers rewriting it "from scratch, like one of those American thrillers, "Halloween" style".
