His best film, when watched in full uncut/non-edited version. Too bad that the American version “Fangs of the Living Dead” has ruined the film’s reputation. Night of the Sorcerers is another good one, trashy jungle horror.
According to some sources he also directed spaghetti comedy Patience Has a Limit, We Don’t. Official credit goes to producer Armando Morandi or Franco Cif(f)erri depending on source. I’d like to know more about this.
