During the sequence of the theft in the house of the alleged connoisseur of the underworld, Remo Guerra tells him: "You see, it doesn't just happen in movies, it really happens too". From that moment it is possible to see on the television behind the attacked the broadcast of the film The Great Train Robbery, a revolutionary American film of 1903, which deals with a robbery. This homage is followed by a real quote in the last shot that precedes the credits: Remo Guerra shoots towards the camera, as happens in The Great Train Robbery.
The film is inspired by the true-crime novel of journalist Dido Sacchettoni: Le notti di arancia meccanica.
Due to the violence of some scenes, some actors suffered minor injuries, for example Valerio Mastandrea did a dislocated shoulder during a robbing scene.
Emanuel Bevilacqua had never acted before this movie, he was noticed and chosen by the director for his rough appearance.
