Revealing mistake: At the beginning of the movie, the coked-up sailor is shooting from a rooftop and screaming various racial slurs. Despite that, there's a big crowd building. When he shouts "Come and get me, honkies!" you can see people running way before he pulls out of the gun again and shoots. Not only that; some of the extras are just enjoying themselves and not keeping a straight face, far from being scared. (00:01:00)

1 revealing mistake
Directed by: Steno
Starring: Bud Spencer, Adalberto Maria Merli, Juliette Mayniel, Raymond Pellegrin
Continuity mistake: Flatfoot Rizzo comes out of the door at the top of the building with an agile tumble. The black sailor shoots him but he's out of bullets. In the close-up with the gun that clicks empty, suddenly large shadows appear on his chest, which were not there when he was shooting in the same spot and pose. (00:05:05)
