Continuity mistake: In the scene when Spider is killed by Tommy, Jimmy is with his arms wide open just the instant before Tommy pulls the trigger. But in the next shot, when Tommy fires the gun, Jimmy is with his arms down.
Continuity mistake: When Paulie and the others are in prison and preparing dinner, there is a vase on the table where they will eventually eat dinner. The vase is filled with fresh basil at the beginning of this scene but disappears and re-appears throughout the scene.
Continuity mistake: While Henry and Jimmy are beating up the guy in the car, Henry is holding a gun up to the guy's face. A few times during the scene, it changes back and forth from the gun pressed right up against his face to the gun a little away from his face. (01:17:50)
Continuity mistake: In the scene near the end, when the FBI agent is explaining the Witness Protection Program to Henry and Karen, the hemline of Karen's dress changes from one shot to the next. First it's down low on her calf, then it's up by her knee, then it's down again, then up, then down again.
Continuity mistake: When Henry comes back from the hospital and is watching the helicopter above, the number of cars behind keeps changing from frame to frame. Sometimes it even looks as if there's just one lane, then two lanes filled with cars, then no cars.
Continuity mistake: When Tommy kills Stacks he shoots him once in the back of the dome, then cracks Carbone's castanets about the coffee. Then it cuts to a slo-mo reprise of the whacking with a Henry voice over and Tommy shoots 6 times.
Suggested correction: After Tommy shoots Stacks in the back of the head, you see Carbone come into the room with the coffee pot, a shocked expression on his face. While the camera is focused on Carbone you can hear Tommy continue to shoot Stacks several times off-screen.
Also, the slo-mo of Tommy shooting Stacks the blood splatter is already on the wall before he shoots him.
Continuity mistake: When we see the close-up of Tommy pulling the ice pick out of Morrie's head, there's lots of blood on the ice pick. But in the next shot, there's no blood on the ice pick. The next shot is a little quick and blurry, but we can still easily see the ice pick's silver when it should be red.
Continuity mistake: After Henry tells Tuddy that he won't be able to make any more deliveries, he points to his black eye. But when the shot changes his hand is suddenly in a new position, down by his side. (00:06:40)
Continuity mistake: In the scene where Tommy shoots Spider in the foot, we hear 7 gunshots from a S&W Model 36 5-shot .38 revolver. [The first gun, not the Colt 45 he kills Spider with later.]
Continuity mistake: After Karen has been with her girlfriends, she is talking to Henry about what is going to happen if he gets killed, at that point Henry is folding his pants by the closet, when the camera angle switches he is suddenly very quick on his knees in front of Karen.
Continuity mistake: When Henry is in the shower listening to the radio news about the Lufthansa robbery, his hair is brushed backwards. Then he starts to shout and it turns to messy and loose, then back to the first angle and it's pressed and brushed backwards as it was the first time.
Continuity mistake: When Henry and his girlfriend enter the Copacabana avoiding waiting in the line, their way through the catacombs of the nightclub is prolonged artificially because they exit the kitchen by the same door they entered it. The scenery is changed a bit by moving some racks and a curtain but you can tell it's the same because they pass the same firehose on the wall twice.
Continuity mistake: When Karen is at the the Hostess party, and Jimmy Conway's wife is talking about Jeanie's family, if you look at the lady she's applying make up to, she crosses begins to herself twice. One when the camera is one her and Jimmy's wife, then again when the camera is just on her.
Continuity mistake: When Tommy is shot, there's no bullet wound in his head, but in the very next shot, there is. And we don't see the moment of impact, that wound was always there in that entire second shot.
Continuity mistake: When Henry beats the neighbor kid and then passes the gun to Karen, her knit sweater is sometimes on one shoulder and sometimes on both arms.
Continuity mistake: When Tommy is shot, Tuddy is holding his shirt, but in the very next shot, he isn't, and he's much further away from him.
Continuity mistake: After Tommy shoots and kills Spider, Henry sits back up and puts his hands down from covering his ears twice.
Continuity mistake: After Karen's been harassed by her neighbour, Henry drives her home and tells her to walk home. When Henry steps out, she's nowhere to be seen. She couldn't have walked all the way to the house in that short time. She couldn't have run, either, being as weary as she was.
Continuity mistake: When Karen is pointing a gun in Henry's face, the close up is different from the one she has in her hands. (01:13:00)
Continuity mistake: When Karen is over Henry pointing the gun at him, the trigger is pulled all the way back. The gun also goes from blue steel to silver.
