Other mistake: It certainly adds very dramatic touch but that a police squad on motorbikes driving by a house makes the cups shake in the saucers is a bit over the top. (02:02:35)
Continuity mistake: During the farewell scene at the harbour, when Giuliano drives off, it gets bright between shots. (02:10:10)
Factual error: After his assassination, Giuliano's body is dropped on the street, and another round is fired into him. In the next shot we see a TV reporter saying something, and there are meter-long rivers of blood running across the street. As he was already dead when he was dropped he wouldn't have bled like that.

Visible crew/equipment: When Don Masino and the professor stand at Giuliano's grave, in all close-ups of the Don's face the padded microphone that is held up in front of him is reflected in his spectacles. (02:15:20)
