Continuity mistake: When Beth is looking for a key in Officer Dawn's office, she encounters Joan lying dead in the office from bleeding out, apparently from suicide with a pair of surgical scissors. Her left hand is covered in blood. But when Officer Gorman enters the room and Joan starts to turn into a walker, the blood on her hand has disappeared.
Factual error: The grenade Rick finds in the tank has an unpainted body and a blue safety lever. It's a dummy training grenade. (00:06:20)
Continuity mistake: Maggie pulls the ladder from the rear of the firetruck, but in previous shots the only ladder on the firetruck is hung on the passenger side.
Other mistake: In the opening scene when the cop stops at the side of the road & walks between the truck & car you can see there is no engine or transmission on the truck lying on its side. (00:00:20)
Other mistake: When Martinez shoots the grenade launcher for a second time the cross hairs are on the concrete wall of the guard tower yet the explosion does nothing to the concrete and destroys the top of The Tower.
Audio problem: In the scene when Andrea is mourning the death of her sister, Rick walks up to "tell her how it is." Andrea points a gun at Rick with just her right hand. When the gun is coming up to Rick we hear the slide being cocked, this can only be done with two hands. (00:03:35)
Knots Untie - S6-E11
Continuity mistake: When the bus gets stuck in the mud, the team leaves the vehicle. However, their shoes/boots are already covered in mud despite having not left the bus yet. (00:17:50)
No Sanctuary - S5-E1
Continuity mistake: Near the end when Rick thanks Tyreese, the cabin door is open after Tyreese had closed it as the group walked up. In next shot it is closed again.
Too Far Gone - S4-E8
Continuity mistake: After The Governor shows up at the prison with his arsenal, Hershel and Michonne are taken out of the vehicles and placed kneeling on the grass side by side, about 1 arm's length apart from each other. But when Rick makes his way down to the fence to talk with The Governor, Hershel and Michonne are now about 4 arms' lengths away from each other. This goes back and forth for a few shots.
Continuity mistake: When the sodas are retrieved from the cool box there are 6 cans, but when the angle changes there are only 4.
Beside the Dying Fire - S2-E13
Continuity mistake: When the farm is overrun, the tires on Daryl's motorcycle are offroad tires. Later in the episode however, these tires change magically to smoother street tires. (00:15:35 - 00:28:40)
What Happened and What's Going On - S5-E9
Continuity mistake: Tyreese, Noah, Rick, Glenn and Michonne all go to see Noah's old base in search of his family. Tyreese gets bit, and they begin to run back to the car. Except for one tiny clip, Daryl is running alongside them, even though he was with the other half of the group. (00:33:15 - 00:33:40)
Chupacabra - S2-E5
Continuity mistake: Daryl ripped off his shirt to wrap around his wound, and was left in only his vest. Except, a shot later, he's seen wearing his shirt again, cutting off the walker's ears. (00:25:30)
Continuity mistake: When Aaron and Daryl are stuck in the van surrounded by walkers, he lights up a cigarette with a yellow filter and it changes to a white filter as he starts smoking it.
Revealing mistake: Near the end of the show, while Rick is still in Atlanta (he is on a secondary paced road), you can see vehicular traffic moving on a bridge in the background.
Continuity mistake: The stinger is deployed and is seen. Camera changes into the car and the stinger has vanished from the road. (00:09:20)
No Sanctuary - S5-E1
Revealing mistake: When Sam has his throat slit, the location of the wound does not correlate with where the blade was shown to be slicing the skin.
Continuity mistake: When Jessie brings a basket of stuff to Rick the paper towels are on her right, then when Rick takes the basket they're on her left, and then in the next shot they're back on her right.
Visible crew/equipment: When Sam comes to visit Carol with items in his hand, he walks through the front door of the house. Carol shuts the door after she lets him inside. As she does this, you can see the reflection of a black sheet or tarp of some kind covering the door area where the camera reflection would be.
