Continuity mistake: When Clay pulls a gun on Salazar, he's holding it sideways from one angle, but holding it upright in the reverse angle. This mistake repeats a few times when the shot cuts. (00:16:30)
Lochan Mor - S3-E8
Factual error: The credits refer to a 'PSNI lieutenant'. The Police Service of Northern Ireland uses standard British police ranks. He would be an inspector.
Lochan Mor - S3-E8
Factual error: Having crossed on the ferry from Stranraer to Northern Ireland, the Sons have a long ride through the Northern Irish countryside before reaching Belfast. However, the ferry from Stranraer docks at Belfast. They wouldn't be going anywhere near the countryside.
Continuity mistake: Gemma pulls up beside Agent Stahl and tells her to get in the car. She has a purse on her shoulder yet when she gets in the car, the purse vanishes.
Continuity mistake: When Jax says to Stahl: "You just signed my death warrant," his hair falls over his ear, yet in the reverse angle, his hair is tucked behind his ear. Strange, seeing how he is being restrained by ATF agents.
Visible crew/equipment: When Jax and Clay are meeting with Alvarez (when they figure out the niners are branching out), the camera man is visible in Alvarez's sunglasses.
Continuity mistake: When Wayne pulls back the blanket to look at Piney's body, he doesn't cover it back up but when Wayne stands up, Piney is covered up again. Wayne is on camera the whole time so he couldn't have covered it back up.
Continuity mistake: The car shown in the scene when Jax and Tara are driving to Oregon is a Jeep Grand Cherokee. When at the gas station and in the park, the car has reverted to the Ford Edge that Tara is seen driving throughout the season. (00:06:25 - 00:15:30)
Continuity mistake: In the episode prior to this one, Clay severely beat Gemma in the face. Bruised and cuts. Swollen eyes. This episode, which is the next morning, her face isn't nearly as bruised - it sure wouldn't have healed that much overnight. And the swollen eyes aren't as bad either.
Revealing mistake: Piney, who has supposedly been dead for days, swallows and moves his mouth while Opie lies crying beside him. It is while Unser is telling him to go see Gemma's face.
Burnt and Purged Away - S4-E12
Continuity mistake: Near the start, Jax Teller's hat continuously turns around over the course of 30 seconds. (00:04:15)
Deliberate mistake: In the chase scene after Jax shoots the unnamed driver, the SUV crashes into traffic. You can see the car that the SUV hits is empty. (00:26:18)
Character mistake: The nurse that was helping the doctor tend to Clay has blood all over her gloves. As she leaves the room, she takes off one glove. No hospital anywhere would allow doctors or nurses to roam the hall with bloody gloves and hands. It's a health hazard.
Suggested correction: She leaves the room with both gloves on. Anyway, this can't be classed as a mistake because you don't see her at all after she goes through the door. She may have taken them off, off camera, as soon as she exited.
But a nurse wouldn't leave the room with them on, even if she took them off in the hall right away.
No doctor or nurse leaves the operating room with bloody gloves on! Come on.
Revealing mistake: In the scene where Jax and crew go to help escort Tig after he ran into Laroy with a car at the cafe, they get caught in a traffic jam and have to drive on the breakdown lane. Jax shoots at the SUV with Laroy and kills the driver and the car slams into a car that is stuck in traffic, but there is no one sitting behind the wheel of that car.
Other mistake: Look at the tombstones in the cemetery. I counted the name Carl Unger 4 times. Also the order of the tombstones changes several times. (00:14:30 - 00:16:10)
Continuity mistake: When the club is voting in the 3 Nomads, the patches change from Nomad, to Redwood, back to Nomad. before the vote.
Stolen Huffy - S5-E4
Continuity mistake: After Chibs says "I don't think you want to be doing this for an audience," Jax holsters his pistol twice. (00:24:40)
Character mistake: Tig gets bit on the right butt cheek. Tara tells Chibs to give him a local, which is a numbing injection so she can stitch him up. Problem is that Chibs does the injection in the left butt cheek. You are supposed to give the injection close to the wound to numb it before stitches.
Continuity mistake: Frankie is staking out Unser's place when he starts up his 1979 T/A, then turns the corner to take off in a 1978 T/A.
Crucifixed - S5-E10
Deliberate mistake: When Tara is talking to Gemma in the parking lot of Stockton Prison, the chrome bumper of Tara's SUV is blurred out, probably to cover up visible crew and equipment. It looks unnatural, since the image is sharp enough that you can see the radiator itself behind the grille, and the numberplate is perfectly sharp.
Suggested correction: You can never assume how someone would heal or swell.
Clay beat her severely. Perhaps you should watch the scene.
