Other: When Rocco taunts the Russians he is punched in the face, yet he continues talking in a steady tone, and finishes his joke while falling into the bar.

Continuity: As the police are investigating the shootout at the hitman's poker game, the first gun outlined on the ground has a red handle and is not a revolver. None of Il Duce's semi-automatic pistols have a red handle, as you can see when he reveals his 6 firearms.

Visible crew/equipment: In the firefight scene, when Rocco and the brothers walk out of the house and see Il Duce, crew members are visible in the sunglasses. The most prominent example is in the head-on shot of the three men with Rocco in the middle. A man in a red jacket holding the camera is visible along with a half-dozen other crew members. Several of the shots between the timestamps have crew members' reflections visible in the glasses.

Continuity: In the scene when Il Duce approaches the house before he begins shooting at the three, he steps in front of a car without a hubcap. During the battle, you can now see a hubcap on the wheel.

Continuity: While Connor is struggling to rip the toilet free, one corner of the tank lid (front right, from Connor's perspective) crumbles and a few pieces break off. Then a few moments later, the chips have vanished and the lid is whole again.

Revealing: In the scene where Rocco kills the two 'goodfellas' in the restaurant, he hides his gun by holding the gun behind his coat. Before the shot switches, you see the gun go off, yet the hammer is down the entire time. The revolver could have been single or double action, but the hammer would still have to have gone back. It is easier to see the gun go off on the NC-17 version or on the deleted scene, but you do see the flash on the R version.

Continuity: After Connor has thrown the toilet off the roof onto one of the Russians and landed on the other, he is unconscious on the ground. While Murphy is collecting things from the ground and the Russians, Connor's legs switch from straight to crossed.

Other: In the scene where the brothers are going to kill the "fag man", the fourth man has his shoulders perpendicular to the brothers in the center of the room but the bullet goes straight through his chest. The shot wasn't even at a close enough angle to go through his chest like that.

Visible crew/equipment: When all the news casters are trying to talk to William Dafoe, after he lets the second man in the door you can see a cameraman and a person next to him in the reflection of the door. (It is too close to be a news reporter).

Continuity: When Vincenzo Lipazzi is sitting next to Rocco, in the shots where he is looking at Rocco, his head and body appear completely straight. In the shots on the side of Vincenzo, his head is turned quite a bit.

Factual error: When the news reporter is at the Lakeview Lunch which is supposedly on Beacon Hill in Boston, below her name it says South Boston, as if that's where they were reporting from.

Other: As Connor and Murphy are wrestling around inside the upper vent shafts, the shaft loosens and the two fall through the ceiling. If you look closely, as the bodies begin to come down, you can only make out one. It seems as if the other is not there.

Revealing: When the one man drops the toilet from the top of the building onto the Russian guy, as the toilet smashes over his body, you can tell it is obviously a fake breakaway prop, as the pieces of it are all practically paper-thin.

Continuity: When they bring coffee to the brothers in the police station, one of the guys holds up the tray and there are three cups visible. The brothers take two and walk away. The next shot is from in front of the brothers, where you can see, over their shoulder, that there is no one holding up the coffee tray. The next shot is of the group again, and the tray is back to being held up.

Continuity: The bag in which Pappa Joe Yakavetta's sandwich arrives changes in different shots. When the camera faces him, the bag is angled toward him; when the camera is behind him, the bag is angled out, away from him.

Factual error: When Papa Joe kills Rocco, his gun, which should have lots of kick, doesn't kick at all, yet this bullet which produced no kick at all knocks Rocco's chair over when it hits him.

Continuity: In the Don's house toward the end of the film (just after the saints are captured in the basement) the Don lights up a cigar and says he's leaving. When he steps outside and gets into his car, you can see a cigarette in his mouth, not the cigar he lit.

Continuity: Right as Agent Smecker shouts "There was a firefight," the Duke is shown briefly. Right before this frame, he (The Duke) already had his guns drawn, yet now his hands are down in front of him, coat closed.

Continuity: In the shootout between Il Duce and the Saints, one of the brother's runs out of ammunition and the pistol locks with the slide back. The camera angle changes and immediately, without loading a new magazine, he fires off two more rounds.

Revealing: Prior to the scene where the trio raids the card game, the three bring the wife, hands bound, to enter the security code. When the guy "cuts" the duct tape, look closely at the wife's hands, the knife never actually cuts the tape; rather he pretends to cut and simply lifts the tape... and voila, her hands are free.
