Continuity mistake: On several occasions, time seems to pass very fast. People leave one place in the daytime, cross town, and arrive at night, even though it is said that the dome is about 10 miles in diameter. It would not take this long to cross town by car.
Continuity mistake: When Junior attempts to find a way out in the cement factory tunnels, he is angered at the fact the dome has cut clean through the factory as well. A few seconds later, Junior turns to the Dome and takes his hood off and yells at the dome. In the next frame with Junior, his hood is back up and he begins punching at the dome, his hood is then removed again. (00:23:25)
Continuity mistake: When Junior is talking with Julia in the cement factory tunnels, Julia lights a match and turns to him. The match's flame changes position every different frame until the whole match is burnt up. (00:29:15)
Continuity mistake: After the shot when Julia is lying on the floor and sees her husband, a 7 of clubs is visible right beside her, underneath her hand. The playing card switches position throughout the next 2-3 shots. (00:28:35)
Blue on Blue - S1-E5
Continuity mistake: At the end of Outbreak, Big Jim finds Angie down in the bunker. Water is flooded everywhere (knee-deep), and Jim has on an orange buttoned long sleeve shirt. When this episode starts, at 2:15 the water is practically gone, and Big Jim is in a blue short-sleeved polo shirt. (00:02:15 - 00:40:15)
Suggested correction: Jim shuts the door when he discovers Angie, then he comes back the following day and that's why his shirt is different.
Continuity mistake: Angie runs out of her house in bare feet, she is wearing flesh colored ballet slippers when running through the woods to escape Jr., and is barefoot again when she runs into the diner.
Continuity mistake: When saving Julia from the gas-jackers, Barbie shoots one of the assailants in the leg, but when we see the same man later on in the episode, there is no evidence that he was shot.
Continuity mistake: Jr. is carrying the salt canister in his right hand as he walks to the cement factory, but in the next shot it's tucked under his arm.
Continuity mistake: When Agatha falls overboard from Jim's boat she is barefoot, but when Maxine finds her body on the beach, she is wearing blue shoes.
Continuity mistake: Near the start, the camera pans out to see the dome now covered in a layer of black. Outside of the dome you can see nice green fields, a small forest area, little houses and everything looks rosy. However a few episodes back the military launched a MOAB (mother of all bombs) and and the surrounding area was wiped out completely. (00:05:50)
Suggested correction: The entire left side of the dome is where the bomb blew up. Now if you watch back when the bomb hit the dome, picture the lake being to the north on the map. When Joe and Norrie were looking for Ange, and they were on the bench when the bomb hit, SW in the scene is a pretty close point to when they show the aerial shots of the dome.
