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.
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.
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.
