Continuity mistake: Yi-Na had her head turned to the right while her dad Sang-Won was talking to her from the front seat and, eventually, Yi-Na closed her eyes. After a camera shift, Yi-Na's eyes were still closed, but her head was turned to the left. (00:04:17)
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 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: Within a scene, Xanthe's disheveled hair often has a different number of curls/waves (especially on the sides) and the tightness/ looseness varies. Sometimes some strands of curls look like loops sticking out sideways; sometimes her hair looks almost straight on one side. The nature of the curls may vary with front and back views at times. In one scene, she had about three loose waves on the left side of her hair then suddenly it looked almost braided (many waves). (00:07:21 - 00:07:51)
Factual error: The film consistently mistakes Absinthe ban with Thujone ban. The United States Food and Drug Administration (US FDA) lifted the ban on Absinthe in 2007, 13 years before the events of this film. Thujone is still banned, and Absinthe products must contain less than 10 mg/kg Thujone content.
Continuity mistake: When the Butcher tackles Millie on the field, in the first shot he's on top of her, and she's flat on the ground. However, when it cuts to the side angle, the Butcher is already getting up and Millie has instantly turned onto her left side.
Continuity mistake: When the Homeland Security guy is sitting in the lobby in Vancouver, Canada, a girl and another man are walking behind him and across the lobby in the wide shot. But when it zooms in on him, the same people and more are walking behind him again as if they never were crossing the lobby. (00:28:45)
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)
Other mistake: The scraping sound is not coming from the man "scraping" his windshield. The snow is easily brushed off and there is no icy coating below the "fluffy" snow to realistically produce the sound of scraping ice off a windshield. (00:00:35)
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: James lit the cigarette he gave Amanda, and she was shown taking one puff. Amanda tells part of the Empty Man story and the ashes on the tip of her cigarette are the same when she takes a second puff. After continuing the story for about two minutes, the length of the ashes still have not increased when Amanda is about to take the third puff. (00:37:21 - 00:39:53)
Character mistake: Jean rolls, kneads, and flattens the dough a few times, repeating the steps to give the image of still preparing the dough. After the dough was flattened, it was well-shaped (round, higher, and more compact) then flat again. The way she was shaping the dough suggests she was making biscuits, but biscuit dough should not be handled that much (or the biscuits would be flat and not flaky). (00:18:00 - 00:19:00)
Continuity mistake: Theodore rides once the tiny rollercoaster; the cart comes to a full stop and his left foot is in the space between the bars, but in the next shot the left foot is on the outside. (00:48:00)
Other mistake: The weapon which the gunman is holding is a WWII era Nazi MP38/40 submachine gun. The weapon from the magazine housing to the end of the barrel (muzzle) is completely bent down about 25-30°. There's no way the weapon would shoot as straight as it was shooting earlier if at all. I highly doubt the firing pin/bolt can even make contact with the primer of the bullet in the magazine. The weapon looks cartoonish if anything. (00:48:30 - 00:50:00)
Other mistake: The entire movie takes place during the overnight dark hours. Limited lighting from the car and flashlight somehow manage to illuminate faces, photos, signs, etc. Filming in the dark surely has its challenges, and there has to be a proper balance between lighting and ability of viewers to see what is happening. The "convenient" lighting would be a "deliberate mistake" except for one factor: A full moon (highly illuminated) is shown without radiating the light expected from a full moon. (00:26:25)
Revealing mistake: Near the beginning of the movie, there does not appear to be a curtain (or window) on the left side of the screen (e.g, when Samantha is sitting on the couch), but there is near the end when Chloe enters the now-empty room. The use of a green screen seemed apparent throughout the movie. (00:04:19 - 01:23:04)
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: The shape, amount, length and width of the white down "Dream Alliance's" face varied, as did the height of his white "boots", indicating that the same foal/horse was not used throughout the movie. The white on the foal's and adult Dream Alliance's face and lower legs looked painted on at times. Before Dream's first race, black tape was used on his lower legs, apparently as an attempt to make a different horse's higher white boots less or not at all noticeable. (00:32:42 - 00:35:51)
Visible crew/equipment: Sara is at the front door video intercom. As the man from the Department of Sanitation is leaving, you can see crew/equipment visible in the reflection. (00:27:15)
Character mistake: Dean told Laura that Fiona's toiletry case was in his bag because "She couldn't fit it in her carry-on, so I put it in my luggage." Laura (who had no reason to fabricate the story to her dad Felix) changed the details, which she couldn't know based on what Dean told her: "There were some of his co-worker's toiletries in his luggage. But she couldn't put them in her carry-on for security, so he offered to put them in his luggage." Unable to fit in isn't the same as "for security." (00:13:05 - 00:23:57)
