Continuity mistake: In the scene that Karen is too afraid to take the clothes and the license plate falls off, there is a shot of the windshield which is close enough to reveal the fake registration sticker made for the era in which the movie was represented. The problem is though that not only is it obvious that the sticker is applied on the outside of the window, but the current sticker (inside the window) is larger than the movie prop and can be seen as a "frame" around the other.
Continuity mistake: When Jimmy and Henry are talking to Morrie and the camera angle is behind Morrie you can see him holding the phone at his shoulder, when the camera angle switches he has the phone at his ear. Then the phone suddenly disappears when you can see both of his hands and then it comes back again right before Jimmy strangles him with it.
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: 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 and he comes in to the kitchen with food in a bag, he first passes some bread to Paul. In one shot he picks up 2 jars and a bottle of wine. The next shot he is carrying the same food but suddenly has a loaf of bread in his hands. When the camera angle switches we now see Henry in front of the table about to sit at the table but now has no food in his arms.
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: Whilst Jimmy is choking Morrie in the wig store the phone suddenly rings and the shot changes. Between shots the way Morrie is standing has all of a sudden changed. Instead of leaning back, he is bent forward. The way he is holding the phone whilst being choked changes as well.
Continuity mistake: Henry and Jimmy are eating in a diner waiting for word about Tommy being "made". When Jimmy goes outside to make the call to find out, there is a car parked outside the diner, at this point, the car's window is open. When Jimmy starts kicking over the phonebooth and Henry comes outside to join him, the car's window is closed.
Continuity mistake: When Paulie and Jimmy go to visit Henry at Janice's apartment to talk to him, after Paulie sits down and begins the conversation, a Star of David necklace can be seen around Henry's neck. The next time the camera is on him, it has switched to a crucifix and remains that way.
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: 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 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 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 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: Paul and Jimmy go over to Henry's girlfriend's place with Henry, and she leaves to get cigarettes. Paul is talking to Henry about having to go back to his wife, and when they sit down, the camera goes on Henry and you can see a Jewish necklace. But later when the camera goes back to Henry, it's a necklace of a cross.
01:16:15 - 01:16:50
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.
