Continuity: When De Niro catches Stone and Woods in the restaurant, De Niro takes out some money from his coat pocket and lays it on the table. In one shot the money is straight, in another it is diagonal and in the final shot before De Niro picks it up it is straight again.

Audio problem: In the scene where Sharon Stone is talking to Joe Pesci about how De Niro had his guys beat up James Woods, at one point Sharon Stone says, "Oh C'mon." If you look closely her mouth doesn't move at all. Also if you listen closely, that line comes out on surround sound. When she continues her line it comes out on mono. It was obviously recorded.

Continuity: In the scene where Joe Pesci tells Robert De Niro that he's moving to Vegas, both of their windows are cracked. De Niro's stays opened the same length until just before the scene ends, when it is opened nearly twice as much as before.

Continuity: When Ace is having a meeting with Green about him firing the cowboy, Ace stubs out his cigarette. In the next shot from behind Ace is still smoking, but when in the front he has no cigarette.

Continuity: When Pesci flings a playing card at the dealer, the card gets stuck in his shirt button but when the shot changes, the card has disappeared nor has it dropped back on to the gambling table.

Continuity: When Ginger is arguing with the gambler at the craps table about "giving her a bigger cut", the man reaches for her purse to show her the chips she's been stealing from him. As she pulls the purse back, the gold chain strap breaks. The next shot of Ginger shows a repaired chain.

Audio problem: Ace yells "come with me now" over and over while dragging Ginger out of the house after overhearing her trying to have him whacked. DeNiro's lips are not moving while he's yelling.

Visible crew/equipment: In the scene where DeNiro is throwing Sharon Stone's character out of the house after overhearing her on the telephone, he drags her into the bedroom. Just before the scene cuts away, the camera appears in the mirror on the wall behind them.

Factual error: When Joe Pesci is driving to meet De Niro, he has to change cars. The scene right before going to the garage, they show Pesci's car driving around a corner and at the bottom right of the screen, you see a lamp post with a bus sign on it that reads CAT. CAT (Citizen's Area Transit) wasn't established in Las Vegas until late 80's early 90's. Before that it was the Las Vegas Transit. This scene was supposed to be late 70's, early 80's...

Other: When news on Robert De Niro not having a casino license first hits the airwaves, the news broadcast displays a still picture of Joe Pesci having a conversation with his friend Frank (I believe his name is). The picture that they use is when Pesci and Frank have tooth picks in their mouths because they don't want FBI agents lip reading what they are saying. But that didn't happen until later on in the movie. So how could they have displayed a picture of a conversation that hadn't taken place yet?

Continuity: When De Niro is proposing to Sharon Stone, the position of his head is not continuous between the front and back shots.
