Audio problem: Rizzo gets interrupted in his 'conversation' with Tom; he shoves away the guy with the horseshoe moustache, sending him offscreen. A noise of broken glasses and cracked wood is added, but in the following part of the scene the club is undisturbed, with a couple nearby and every table intact. It's only a minute later when the big guy comes back with a vengeance, that stuff starts breaking and people acknowledge violence happening nearby. (00:36:40)
Continuity mistake: Searching Tom Ferramenti, Rizzo finds brass knuckles and a knife (plus dollars and jewelry). He then puts his hand on Tom's shoulder (he is leaning against the wall with the left). So, all the stuff he confiscated vanished in thin air. And at the first cut, his hand too disappears, being suddenly off Tom's shoulder. (00:36:05)
Continuity mistake: Talking with his new and still wet behind the ears boss, Rizzo advises him against trying to blitz the one-handed delinquent. He is making a gesture with his right hand, but at the cut here he is moving his left hand instead, with the arm that suddenly is on the table. (00:27:15)
Continuity mistake: Visiting the prostitute scarred with the sharpened coin, Rizzo looks at her in her hospital bed. In her close-up she is holding the bed sheet with both hands, but in the wider views before and after, nothing of the sort happened, her hands were off the sheets. (00:18:00)
Continuity mistake: Rizzo breaks up the rumble at the pizza joint; in the wide shots when he keeps the goons in check, there are several more unperturbed bottles in the shelves behind Manomozza than in close-ups. Some of the bottles that were in the side shelves in fact have inexplicably moved onto the center one. (00:11:25)
Continuity mistake: The protagonist is having lunch with the landlady and her son, who asks him a question. Before doing that, he puts down his fork. But in the next shot, he is holding it in his hand. (00:14:25)
Continuity mistake: To throw the crazy shooter off and make him waste bullets, Rizzo tosses his jacket, which ends up behind the row of chimneys. At the end of the fight, Rizzo picks up the gun and the jacket; the gun is facing the opposite direction compared to when it was dropped, and the jacket is by the open door, an entirely different spot. (00:05:00 - 00:06:40)
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)
Continuity mistake: When Rizzo and the sailor wrestle atop the building, in the views from outside the building Rizzo has the lead pipe pressed against his ursine neck, while in the shots from the terrace it's further away. (00:05:40)
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)
