Commendatori - S2-E4
Continuity mistake: Christopher is shown exiting through the revolving door twice. (00:49:45)
Continuity mistake: Tony's hair length alternates between a short buzz cut and longer in different shots in the scene where Sil, Paulie and Chris visit him after his mother dies.
Guy Walks Into a Psychiatrist's Office - S2-E1
Plot hole: In this episode Tony tells Janice that he has just put their mother's house on the market. In season one, the house had already been sold.
Suggested correction: Tony and others say many things that aren't accurate. While season one gives the firm impression that the house is sold, it's not confirmed on screen. There may have been a deal where the intended buyer couldn't get financing or a closing never took place for other reasons.
Knight in White Satin Armor - S2-E12
Continuity mistake: When 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.
Suggested correction: Actually, her tattoo is visible. The style of the wedding dress she had on was obviously chosen for the way that it NEARLY covered up the tattoo. It is easily seen if your eyes are not glued to her cleavage near the 19 minute mark.
Sorry. There is no way her tattoo is covered up. I looked at the prior engagement party scene and jumped to the wedding dress, this is an error. There is no covering it up.
The tattoo is there and it is definitely covered up. Look at her right boob, not left, since we are seeing a reflection of her in the mirror, and you'll find that tattoo all right.
Suggested correction: Actually there is more than one shot where you can't see the tattoo at all. It depends on the angle. In most shots the top of the tattoo is always visible and in others it's not at all.
I Dream of Jeannie Cusamano - S1-E13
Revealing mistake: When the shrink locks the door on Tony, they argue and she calls the police. When she finally calms down she approaches the door to unlock it but you can see the door move before she ever sticks a key in it or touches the knob. (00:25:20)
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)
Knight in White Satin Armor - S2-E12
Continuity mistake: The location of the gunshot wound changes when Janice shoots Ritchie the second time. First shot shows up high on left side. Next shot shows in center of chest. (00:44:07)

Visible crew/equipment: As the ducks fly away, a crew member can be seen stamping their foot in order to scare the ducks. (00:06:40)
Visible crew/equipment: Right at the beginning of the episode, Chris pulls over in front of the Bahama Skies tanning salon to pick up his pay. The shot shows him in the car. As he exits the vehicle, the cameraman can be briefly seen in the reflection.
Unidentified Black Male - S5-E9
Continuity mistake: Carmela's lawyer is holding a pen with his right hand. From a different angle, the pen is lying on a paper on the desk.
Revealing mistake: When Patsy knocks down the black guy with the iron pole, the pole breaks in half like a piece of plastic. When it cuts, the pole is intact.
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.
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.
Guy Walks Into a Psychiatrist's Office - S2-E1
Visible crew/equipment: In the scene right after Tony is talking to Janice by the pool, when it cuts to the Bada Bing and we see Chris in the mirror, there is a very noticeable cameraman standing behind him. (00:26:50)

Continuity mistake: When Tony and Janice are discussing the DNR, there is a piece of black ribbon hanging from Janice's necklace in some shots, which is not there in others.
Guy Walks Into a Psychiatrist's Office - S2-E1
Revealing mistake: Christopher is seen sniffing some lines of coke, but he is just moving the dollar bill up and down not sniffing anything at all.
Nobody Knows Anything - S1-E11
Character mistake: When Tony tells Dr. Melfi he feels as though a safe might fall on his head, she replies, "a feeling of pending doom." A woman of her intellect and education should know the proper word is "impending." "Pending" means something awaiting a conclusion. "Impending" means about to occur.
Continuity mistake: The size of the hole made by Tony Blundetto on the wall keeps increasing and decreasing all the time.

Continuity mistake: When the nurse brings Livia her ice cream, the apple juice carton on the tray moves between shots. Sometimes it is in front of the tapioca, sometimes beside it.
