Other mistake: In the scene where Janice is trying on her wedding gown with Carmela, her tattoo is gone. However, in all the other shots, her tattoo is ABOVE her cleavage line between her boobs. It's nowhere to be seen in the wedding dress shots.
Plot hole: In the scene where the FBI plays the tape to Tony and reveals the conspiracy between his mother and Junior, it is stated that the bugs were placed at Green Grove. However, the second conversation played in the sequence actually took place outside a movie theater the episode prior, which would not have been recorded as part of the Green Grove surveillance. The conversation involves Livia telling Junior that Tony reminded her of her cousin Kiki after she had her lobotomy.shelbourne
Factual error: During Tony's assassination attempt he struggles with one of the "hit men" for control of a pistol. One can see that the pistol does not contain a magazine.This would limit the shooter to 1 shot, providing the pistol is not equipped with a "magazine disconnect" if it is than it can not be fired at all. It seems unlikely that a "hit man" would be so ill prepared.
Continuity mistake: In the scene where Bacala is telling Uncle Jun about his father and the accident, Uncle Junior gets angry and starts throwing things around, he is wearing glasses. You can see that in between throwing one of the items, he is not wearing his glasses, then he is wearing them again.
Continuity mistake: Tony, Carmela and AJ are meeting with AJ's college tutor. Partway through the meeting AJ is asked to leave. When AJ stands up he is wearing beige coloured trousers, but as the shot changes to show him walking out the door, he is now wearing black trousers. (00:15:30)Rob Butler
Continuity mistake: When Paulie Walnuts is talking to Tony in the hospital room, the close up of the heart monitor shows the heart rate in highlighted text, with the word "Tachycardia" flashing. In the shot from Paulie's point of view, the heart rate is in normal text and "Tachycardia" is not flashing.wizard_of_gore
Continuity mistake: At the end of the show, Tony is making an ice cream sundae for himself and A.J. He gets a Path-mark store brand aerosol can of whipped cream. When the camera cuts to closer look at Tony the can changes to a Redi-whip brand of whipped cream. (00:49:00 - 00:50:00)djrez79
Revealing mistake: While Christopher and Furia are dismembering Richie Aprile on a meat saw, you can see that the blade of the saw is still, but the blood is splattering all over the place and you can hear the sound of the meat saw cutting through flesh. (00:49:55)
