Continuity mistake: Towards the end of the movie, when they first kill Nicky's brother, Dominick, and they throw him in the pit, his full chest is covered in blood, but in the aerial shot it is clean with just the bloody face.
Visible crew/equipment: When Ginger obtains the deposit box's key after having rushed to Ace's house and goes to the bank to open the deposit box, a boom mic can be seen reflected on the bank's glass door.
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.
Continuity mistake: After the very tense encounter between Ace and Nicky in the middle of the desert with De Niro watching Pesci leaving quickly, the distance between Ace and his car changes enormously in two different shots.
