Other mistake: Guido Mauri spots the police from the window. He tells his accomplice to go while he'll draw the guards' attention. Thing is, Marco is leaving through the same door they came from, and the police is already there. Yet he manages to slip unnoticed. Moreover, he leaves to Guido's right, but in the reverse shot you can see someone's head pop in frame on Guido's left for a moment. (00:04:10)
Other mistake: Guido runs over the brigand who just gunned down his woman (and that for some reason is eager to literally jump in front of the car despite being in perfect safety before). The car approaches the lorry driving on sunny asphalt already bearing in front of the car clear marks of the dangerous overtaking. In the next shot the marks are gone and so is the sun. (00:11:00)
