 The film ends with a reprise of the "Identity Crisis" video, now interspersed with clips from the story.Prior to directing "Monster Dog", director Claudio Fragasso had been working as a screenwriter since the mid-1970s and by the 1980s often worked with Bruno Mattei on women-in-prison films and gory horror films.While often co-directing films with Mattei uncredited, he moved his work to Spain for his film "Monster Dog".
