Visible crew/equipment: After Henry pistol-whips his neighbour he goes to Karen's home. She opens a glass door and a boom mike, set lights and crew are reflected on it.
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: 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.
Visible crew/equipment: When Henry comes out of jail and hugs his wife a boom mike is reflected on the glass of the car door.
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.
Factual error: When Henry and Karen are racing to Karen's mother's house when the helicopter is following them, the driveway Henry pulls up in has a 1982 or newer Pontiac Bonneville, but the scene was supposed to take place in 1980.
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.
Factual error: When Henry Hill is at the hospital, the doctor gives him a 10 mg Valium pill which is brown. In reality, Valium 10 mg is light blue and has a "V" shaped hole in the center of it. The pill appears to be an Ecotrin, which is a coated aspirin tablet.
Audio problem: In the bar scene where Tommy gets enraged at Billy Batts, at one point Billy says "Salute Tommy" but his lips do not move.
Visible crew/equipment: When young Henry is parking a black car, a crouched cameraman on the right is reflected on the front part.
Other mistake: Even though this is a fictional event of how Billy Batts was murdered, he was a made man in the Gambino Crime Family. So, it doesn't make sense for him to have a party of him coming home from prison at a rival family's establishment, meaning Henry Hill's club, which was a Lucchese Crime family hangout. He would have had the celebration on his own turf, around his own family.
Suggested correction: While there is no way to prove how factual it actually is, this is almost exactly the way the real-life Henry Hill told the story in the mafia memoir, Wiseguy. The only differences being that Batts was not killed that night, but a couple of weeks later, and Henry did not own the club, Jimmy did.
Well, that isn't at all the disagreement here. My only concern was, why was a Gambino made man having a party at a rival family's establishment and not on their own turf? That's the blooper here.
Character mistake: In jail when they're all sitting down to eat, Paulie says "c'mon boys let's eat, Freddie, Vinnie let's go" The problem is the other guy's name is Johnny Dio, not Freddie.
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.
Visible crew/equipment: When James is in the phone booth and he gets the call about Tommy, the camera moves in really quickly. The reflection of the lens is visible for some time as James talks on the phone. Left of screen.
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.
