Continuity mistake: 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 Frankie. The picture that they use is when Pesci and Frankie 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?
Suggested correction: Pesci can be seen holding and/or chewing on a toothpick multiple times throughout the movie, so it is more than likely that the picture was taken at a different time by a reporter while Nicky was seen in public.
Factual error: About a half hour into the movie, Nicky goes into the sports book to collect. There is a cigarette machine behind him and the price of a pack of cigarettes is marked $2.50 In the 70's a pack of cigarettes was more like one dollar. (00:33:04 - 00:33:35)
Suggested correction: Not only were vending machine prices for cigarettes higher to begin with, they simply jacked the prices up because they could. Think about how much a soda costs at a movie theater or airport.
I remember buying cigarettes out of a machine in the 80's - never needed more than 4 quarters.
There was a news report from 1988 still available online where a small pack of cigarettes from a vending machine was $3.50 (14 quarters). You must have found a super cheap machine selling very small packs and you weren't buying them in a betting parlor.
There is a huge difference between early 70's and 88.
That wasn't the point of my comment. Whoever said they never paid more than $1 in the 80's isn't remembering right or fibbing (which is why I didn't include it in my correction). The correction is still valid because the cigarettes weren't being sold in stores. Just like one time I had to paid almost $10 for a "$5 footlong" at an airport Subway or $3 for a vending machine soda at a theater when they were $1 at every other vending machine.
Character mistake: At their wedding reception when Ginger is talking to Lester on the phone he reminds her of when he watched her as a young "long legged colt." As a juvenile female horse she would have been a long legged filly.
Suggested correction: No mistake. Not many people know the terms of young and old animals. I myself don't often hear a juvenile horse called a filly, so I don't remember that when I see one.
