Continuity mistake: The scene filmed in 'Daves Bar-B-Q' is across the street from a bank that has an outdoor sign indicating time and temperature visible through the restaurant window behind Vinny. When the meal begins, the time is in the 12:00 o'clock hour. Seconds later when the clock is visible again the time is in the 4:00 o'clock hour. The judge only permitted a 60 minute recess.
Continuity mistake: At the scene where Vinny and Mona are at a picnic, they take their platters and have plastic silverware wrapped in a napkin. When they go to sit at the picnic table, Vinny places the wrapped silverware next to his plate, then picks them up to eat, but in the following shot, he does the same thing again.
Continuity mistake: In the scene where Vinny tells Lisa "Do me a favor, don't read this book, OK?" there is a shot where her hands are folded near her face, the next shot of the same scene he pulls the book away from her and her hands are now in her lap. The camera shot changes several times. With each new shot, her hands move back and forth between her face and lap.
Continuity mistake: In the scene where Vinny and Mona are talking in the DA's office, look at the computer monitor sitting on the desk. In one shot, you see the sun from the blinds hit the screen. When you see the monitor again a second later, there is no light hitting it and the monitor is moved slightly.
Continuity mistake: The whole scene between Vinny and Lisa at the BBQ joint looks like it was shot in pieces at different times. When Lisa tells Vinny she got "stiffed" and while he is saying "Whoa whoa, what do you mean?", there are two camera angle shots. Lisa's plate moves closer to her; her corn on the cob, sauce cup, and soda-straw wrapper all change positions; Vinny goes from lifting a forkful of food toward his mouth to having no fork in his hand at all; Vinny's Coke can moves closer to him.
Continuity mistake: In the scene towards the end of the movie after the case is won and Vinny is walking out of the courthouse, Stan, the sheriff, Bill, and Mr. Trotter all take turns congratulating and thanking Vinny. Pay close attention to the shot where Mr. Trotter is congratulating Vinny. In the background you will see a woman with a very bright red sweater leaving the courthouse, then after the judge has congratulated Vinny and everyone is waving as Vinny and Lisa drive away, you will see the woman in the red sweater leaving the courthouse once again. Also, in the same scene during the part where everyone is waving as Vinny and Lisa drive away, look to the left side and you will see three people standing in front of the courthouse, in particular a man wearing a hat, leather jacket and jeans. In the very next shot, when the woman in the red sweater leaves the courthouse for the second time, you will see the same man along with the other two people leaving the courthouse walking behind the woman in the red sweater.
Continuity mistake: When Vinny is showing one of the witnesses the pictures with the trees and the dirty screen, if you look at the pictures (as Vinny is holding them) you can see the last one has a blue back. When the shot changes, the last picture has a white back and the blue backed one is further up in the stack.
Continuity mistake: When the Judge asks Vinny if his clients are guilty or not guilty, he does not have his fingers on his cheeks. Then in the next shot of Vinny answering the question, we see the Judge has his fingers on his cheeks. But when the shot goes back to the Judge telling Vinny that he doesn't understand the question, the fingers are not on his cheeks anymore.
