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: 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.
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.
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.
Continuity mistake: During the scene in the office of Bada Bing, Pauli, Christopher, Tony, Silvio and Pussy are all together and the TV is on. Pussy is reading something and Christopher is lifting weights. In between shots, the weights change from Chris's right arm to his left and back again. It could be argued that he changes arms when the camera is off him, but there is one instance where it definitely happens too quickly for this to be the case.
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.
Continuity mistake: When Meadow is looking mournfully at the Scrabble board, she sees that Jackie laid "the" using the letter e from "oblique" that she laid. However, when they were playing the game, the only word after oblique that Jackie laid before leaving was "ass".
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.
Continuity mistake: In all of the episodes where Carmela hosts her film club, the theater seats in the Sopranos' screening room are gold, attached with wide trays for snacks, beverages, etc. But in this episode, when Tony and A.J. move the seats outside, they are maroon, without the wide trays.
Continuity mistake: When Tony Jr. reads the newspaper, his part of the table changes completely: The napkin changes position, the orange juice comes closer to his arm, the spoon in the bowl changes positions, and a mug in front is replaced for a load of papers. The position of his thumb also swaps from being beneath a photo, to on top of it depending on the angle.
Other mistake: In the scene where Paulie Gualtieri goes to confront "Feech" La Manna at the bakery concerning the landscaping feud, the clock on the wall doesn't match the time on La Manna's watch or the clock on the wall behind La Manna's desk. The big clock says 11:55 while the other two say either 2:45 or 9:10.
Continuity mistake: Ralph and Jackie are in Rose's kitchen talking. After Jackie pours a box of Trix cereal, he sets it down with the front of the box (Trix is showing) facing the camera which is set awkwardly on the counter - it is not set down flat on the counter. For the remaining shots of the scene showing Jackie, the cereal box is now flat on the counter with the back of the box facing the camera.
