Visible crew/equipment: In the show's opening title sequence, in the moment where Tony Soprano passes with his car through the tollbooth, the cameraman's legs, sitting next to him, are reflected on the windshield.
Revealing mistake: In at least one scene at the Bada Bing, the neon sign reading "Satin Dolls" can be seen reflected in the mirrors. Satin Dolls is the name of the real strip bar where the Bada Bing scenes are filmed.
Other mistake: The set up of Dr Melfi's office makes no sense. Her office is in a building with other doctors,yet there's windows on the right side of her office where another doctor's office is.
Continuity mistake: During the show's opening credits for the entire run of the series, when Tony drives up to the NJ Turnpike toll gate, the lane 7 machine spits out a toll ticket, and Tony reaches for it. It then cuts to a close-up as Tony grabs hold of the toll ticket, but this ticket machine is now different; note all the stickers. The close-up was shot at another lane's ticket machine.
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)
Revealing mistake: When Tony collapses in his back garden, and the barbecue grill explodes, some coals (supposedly thrown into the air by the explosion) land next to Tony's body. Watch this moment closely however and you can see that the coals come into shot from left of the screen and not above from the air as they should. Obviously thrown in by a nearby crew member, just off-screen. (00:19:48)
Continuity mistake: When Christopher is trying to get rid of the body into the bin, his arms are constantly changing between crossed and hanging at his side. (00:30:30)
Visible crew/equipment: As Alex, Salvatore and Hesh walk along the bridge, if you watch the right side of the screen you can see a crew member wearing a purple T-shirt and holding a piece of equipment high in the air. (00:39:39)
Continuity mistake: Tony gets out of the car near the start and there is no glass on the floor, when he calls Christopher over, broken glass on the ground has appeared.
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.
Visible crew/equipment: After Dr. Melfi tells Tony, "I know seniors who are inspired and inspiring," when it cuts to Christopher and Brendan waiting outside the club, the red T-mark taped to the ground is visible at Adriana's feet.
Continuity mistake: When Tony shows up at Livia's house with a bouquet of flowers, in the exterior shot note the transparency of the screen door's glass, the front door silver-color knob with its back plate, as well as the deadbolt cylinder. As Tony enters the doorway in the next interior shot, we cannot see out through the screen door's glass, the door knob is gold-color, and both the knob's back plate and the deadbolt cylinder have vanished.
Visible crew/equipment: Livia tells Tony that Junior was looking for him and that he sounded agitated. It then cuts to a long shot of Satriale's, and at the right side of the screen, we can see the reflection of the boom operator holding up the boom pole/mic.
Visible crew/equipment: When the load of DVD players is brought to Bada Bing, just as the guys begin removing the boxes from the car's trunk, the reflections of the crew and the boom pole are visible on the car's surface.

Visible crew/equipment: When Tony and the other guys visit Jackie at the hospital, there's an actor's tape mark (toe box type) on the floor, between the bed and the green chair.
Answer: That's not Jimmy, just a look-a-like. Jimmy's short and stout, the guy in "Christopher" episode is tall and medium built. The hair is also different.
