Continuity mistake: It's the scene where Henry and Karen are visiting some friends and they have their children with them. Henry starts to greet his friends, he is then carrying a big brown teddybear in his hand. Then Paul starts talking to him about Billy for a while, when the camera then is behind them as they walk away Henry is holding a little pink teddybear and he had no opportunity to switch.
Continuity mistake: The scene in the restaurant where Joe Pesci messes with Ray Liotta saying, "What, am I funny, am I a funny guy to you?" watch the drinking glasses on the table. The drink levels are going up and down with and then without ice.
Continuity mistake: When Tommy is having a go at Henry in the Copana bar about saying he's a funny guy, the shots from behind Tommy, Henry has his left elbow leaning on the table with a cigarette in his hand. In the reverse shots(behind Henry) his arm is down. This continues throughout the "How am I funny" speech.
Continuity mistake: In the scene after the 'robbery' of the suitcase of cash by Henry and Tommy, Pauly, Jimmy, Henry and Tommy are all celebrating their success, laughing etc. with the suitcase of cash on a table. While Pauly is telling Henry to tell anyone who asks that he won the money playing craps in Vegas, Jimmy is standing quite some distance to the left of Henry.When the camera closes in on Henry and Pauly, Jimmy has moved positions - he is now directly behind Henry's right shoulder (on the left of shot). This is obviously for effect so Jimmy can be seen laughing in the background.
Continuity mistake: When Henry is in prison, Karen comes to visit him and drop off goods she smuggled in. They begin to argue while Henry is holding his daughter and Karen starts placing all the goods on the table. The camera angle switches to just a view of Henry's hands gathering the goods and if you look carefully, you will notice that BOTH of Henry's hands are collecting the goods. This would be impossible considering he is holding his daughter in one of his arms. Once the goods are collected, Henry is seen holding his daughter again.
Continuity mistake: When Ray's girlfriend is showing off her apartment to her two girlfriends they walk down the hall to the bedroom. The camera then changes to them entering the bedroom door and the order of girls has changed.
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: 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 Henry is visited in jail by his wife, his daughter turns her face away to the right. From the opposite angle she's in a totally different position and also a toy has appeared in her hand.
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: 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.
