The whole film is about Robert Hoffman and Lisa Gastoni. They are both very beautiful, it's true, but they do the same thing again and again, in Milano, Como, Nice, Paris, etc. Gian Maria Volontè, the greatest actor of all time, has just a smaller role. The music of Ennio Morricone is good. Carlo Lizzani has directed much better films as "The Violent Four" (1968)Banditi a Milano (original title), with the same Gian Maria Volontè, but in a super role, or "Torino nera" (1972), with Bud Spencer, Françoise Fabian and Marcel Bozzuffi.
