Continuity mistake: The position of the dead (imposter) security guard's head over the barbell changes. When Gus says, "Jesus, he's dead", the security guard's neck is over the barbell rail, the top of his head is touching the floor, and his face is toward the front of the screen. When the camera goes to the opposite side of the dead guard, his head and neck are raised (and apparently no longer being supported by the barbell - or anything else). (00:28:28)
Continuity mistake: At the "Wave Hair Salon", Ms. Gordon has a curler/roller at the top of her forehead. In some shots, it is straight, but in other shots it is angled. A little later, Christine goes over to Ms. Gordon and starts rolling down the curler to the top of her forehead as if for the first time. (00:08:04 - 00:08:47)
Continuity mistake: Kelly was wearing a white thermal top over a white sleeveless undershirt. After he was thrown into the garbage can, his white thermal top was wet against his back, so he was no longer wearing the undershirt. (00:03:54 - 00:05:43)
Continuity mistake: When the family stopped along the road for a break, the car towing the camper was parked diagonally to the left (not aligned with the camper). The car was visible behind Alan when he was talking to Ben, but it was not when Alan was walking toward Tyler and Charlie. Also, Alan and Ben were at various distances from the camper. (00:13:16 - 00:14:20)
Continuity mistake: The amount/shape/size of the blood/cut on the bridge of Joey's nose varies, as does the obvious presence or absence of blood on the right side of his nose. (00:42:32 - 00:43:50)
Continuity mistake: While on-stage addressing the crowd at the Apple Festival, Vivian's long hair is in various positions. On her left side, a long section is in front of her initially, then in back. On her right side, her hair is either distinctly split (some in front, some in back) or flows around her shoulder/side. (00:09:43)
Continuity mistake: The grilled cheese sandwich was charred while it was still cooking, but not when Jason's dad served it to him. (00:02:00)
Continuity mistake: The fragments from the truck's taillights that Cassie smashed with a tire iron were obviously "neatly rearranged" (and looked resized to be more uniform) before showing them after the man drove away. Cassie hit the outer sides of the rear taillights and fragments of various sizes scattered, so all would not settle close together along the bumper. One large fragment from the passenger side flew past Cassie behind the truck and landed about three or four feet away but was not there afterwards.
Continuity mistake: The replay of Bart and Andrea's conversation at check-in are not verbatim - at times, only a word or two ("uh", "um", "just") is added, but other times there are parts that simply were not stated. Granted, Bart is practising and his additions are not meant to be a reflection of what was actually stated, but the things Andrea said were on tape and these do not always match. Bart did not ask, "Seven nights?" and Andrea didn't reply, "Yeah. A week, maybe longer. I'm not sure yet. So, you're new." (00:27:14 - 00:28:47)
Continuity mistake: After PJ lets Officers John and Julia inside, there are a few continuity errors with the box on the table and the lamp's cord. Initially, the white evidence box is flush with the counter and the front side (with a hand slot) is facing the lower right corner of the screen. Later, the box is closer to the edge and the front side has been turned about 45°. The lamp's cord is sometimes flat on the table but other times there are two upward loops. The box and cord each change a few times. (00:34:09 - 00:35:15)
Continuity mistake: In the opening scene, pay attention to Evan's girlfriend's glass. When Isaac gets up and goes inside, the amount of liquid in her glass slightly changes between shots.
Continuity mistake: When Nick leaves to deliver presents he walks out the door and you hear the door close. When his wife goes after him with the flask you see him opening the very same door he's just walked out. (00:24:50)
Continuity mistake: The sizes, locations, and smoothness of the pieces of glass remaining in the wall mirror after Aidan smashes it with a bat change. Initially, there were a few large and several smaller jagged-edged pieces around the top and upper-half of the right side. Later, there were four relatively large smooth-edged pieces spaced around the upper half of the mirror - one in each upper corner and one on each side at the middle. (00:15:48 - 00:19:33)
Continuity mistake: In the locker room, an adjacent locker is closed then open with a yellow shirt hanging inside. Also, Ali takes a uniform jacket out of the locker Borz said she could use and holds it in front of her while they were talking. When they're almost done, Ali is turned around toward the locker and starts to remove a uniform jacket from her locker (as though this is the first time she was seeing it). (00:10:52 - 00:11:35)
Continuity mistake: Whilst Jung-seok is driving with his family on the first day of the zombie outbreak, after he says "All other roads must be blocked", his sister looks to the left to face her son in the back seat. The shot then cuts to focus on Jung-seok, and the sister can now be seen looking straight forwards out the window. (00:01:45)
Continuity mistake: The amount and location of dirt on Christine's face is inconsistent, ranging from being very thick and obvious to barely visible, if at all. Sometimes it extends down her neck on the right side. When her hair covers most of her face, no dirt is visible - until she turns her head and the hair is away from her face. The intensity and location of the redness on her neck also varies. (00:03:31 - 00:04:48)
Continuity mistake: The flatbed truck that Kyle and Swin got in at the onset of their trip is very different when they parked and went to buy rope (but got tape). The truck style is different, the cargo and its cover have changed (tarp is smaller, a different color, and is wrapped across instead of front to back), and the orange cone/cones change locations. (00:06:34 - 00:08:22)
Continuity mistake: Brahms was quite clean for having been buried under dirt and leaves. No dirt fell off Brahms' body when Jude pulled him out of his "grave" and there did not appear to be dirt in his hair. When Sean (Jude's father) held up Brahms, the doll looked relatively clean - or cleaner compared to when Liza (Jude's mother) started to wash him. (00:14:10 - 00:15:45)
Continuity mistake: When Dellinger is about to leave home to Chicago her wife's hand swaps between being on the boy's shoulder or over his left bicep.
Continuity mistake: Theo lays Susanna's phone down - when it cuts back to her phone is lying in the opposite direction.
