Continuity mistake: During the introductory meeting with Nicole Kleiber, her glasses on the desk switch back and forth between open and folded. (00:26:20)
Continuity mistake: Take notice of the desk lamp as Charlie and Al are talking in Charlie's new office. As the camera switches back and forth between their face to face conversation, the green glass cover of the light keeps changing position too. This happens even after Al leaves. This was probably done to keep the light out of the camera during filming. (00:13:50)
Continuity mistake: Theo lays Susanna's phone down - when it cuts back to her phone is lying in the opposite direction.
Continuity mistake: The first time we see the girl the main character fawns on, people on the background keep changing between shots during the beach volley game. (00:08:20)
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: After the scavenger hunt goes live, Jennifer follows it with her grandmother Sue and Aidan does so with his niece Emma. Aidan looks at the photos of participants and sees one of Jennifer and Sue at the art class, and right below is one of him holding Emma with the carollers in the background. Immediately after that, he picks up Emma in front of the carollers and takes the photo he had already been looking at.
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: 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: When Grandpa shows his old phone to Sally the way he holds it differs between the front and back shots.
Continuity mistake: When Joe is first in the cat and him and 22 see each other, the cat has a harness on. In the next shot when they leave the room, the harness is gone. (00:38:20)
Continuity mistake: Isaac is wearing tan or khaki pants but the video of him getting "beamed up" to the spaceship shows dark blue pants. (00:18:15)
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: Mara is wearing a white long sleeve jersey when in the Dalton twins' car accident and when Dylan finds her in the water washing off blood. Dylan offers her the gray sweat suit he has in his backpack, but Mara says she isn't wearing it (because they wore those clothes at the police station). When Mara stands up, she has on a dark green T-shirt with a lighter green large circular design on the front. Mara is wearing the green top when she gets to quarantine, as well as later in the movie. This is obviously Mara's top, so where did it come from after she refused to wear the gray sweat suit from Dylan's backpack? (00:33:42 - 00:35:02)
Suggested correction: After rewatching the movie, I noticed that Dylan was POSSIBLY wearing this T-shirt under his jean jacket on his first day of school; the shirts look similar, but little can be seen because it is under the jean jacket. At the same time, Dylan's backpack at the accident scene did not look full enough to contain both parts of the sweatsuit, so it is a stretch to believe the T-shirt was also inside. Moreover, Dylan told Mara that he had a crush on her for two years, so the "old" T-shirt would have just happened to be in this backpack under the sweatsuit worn at the police station. Dylan is thinner than Mara, so it is unlikely that his T-shirt would fit her. When I rewatched the movie, I noticed that the T-shirt in question looked navy blue when Dylan had it on but green when Mara was wearing it.
Continuity mistake: Mikey and his friend are smoking the same inch-long joint by the back door which gets passed back and forth - no way they could keep holding/smoking it for that long given how short it was to start with. (00:04:50)
Continuity mistake: Adam has connected strands of hair across his right cheek that are no longer there when the camera switches direction. (00:51:22)
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 kids are in the car with their dad, and despite the best efforts from the youngest, they are reached by his teacher. As the dad starts the "You were killing us" joke, his hand is on/off the steering wheel between shots more than once. (00:07:15)
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: The color of Lance's clothes change from a dark tan, brown, or grayish color on the train to blue walking through the train station and riding to Jack's place. Lance also has his jacket on the entire time - until he is at Jack's front door (where the jacket is no longer visible). Jack kept his coat on in the car, his apartment, and to play cards. (00:03:44)
Continuity mistake: The view of the restaurant and other businesses along the same street are quite different when Pedro exits the restaurant compared to a little earlier when Emma brought Oak the guitar. Store fronts are not the same, the position of a garbage can changes, the restaurant has some outdoor tables and umbrellas, and there are brick borders around the trees and garbage cans. (00:12:34 - 00:14:18)
