This movie got a whole new life as part of Quentin Tarantino's Jackie Brown. The character of Melanie (Bridget Fonda) is watching television, and Samuel L. Jackson's Ordell Robie, when the main star is on the screen, walking forward (after having attacked the girl), Robie says, "Rutger Hauer?" and Melanie corrects him, "Helmut Berger." Scenes shown include Berger slapping the ingenue, and he and his men getting gas. The soundtrack is also heard very loudly.
The father and daughter who are kidnapped are father and daughter in real life: Claudio Gora and Marina Giodana.
A sequel to the film was discussed but never materialised which would have had Vitalli escape prison again this time to seek revenge against a gangster that killed his sister. The film would have ended with Vitalli escaping to the USA.
The last name "Barbareschi", a character the ingenue was dating and who had double-crossed the main character, is uttered a large number of times by almost all the characters, on either side of the law, throughout the film.
On a section 3 video nasty list that were liable to be confiscated under a 'less obscene' charge, which allowed the police to seize a film they considered obscene and as long as the dealer cooperated.
