Continuity mistake: The wall clock, after staying at around 10:12, jumps 4 minutes (to 10:16) in less than 20 seconds. (00:01:05)
Factual error: While playing soccer in the background, Ali's "credentials" were displayed across the screen. Under "Academics", Ali is listed as "MEMBER OF THE NATIONAL HONORS SOCIETY" - but "Honors" should be singular ("Honor"). It is also odd to state "All 'A' honor roll." With a GPA of 4.3, something to the effect of "Highest Honors with Distinction" would be more likely. [It is possible to receive a "B" in an Advanced Placement course yet have a GPA above 4.0.]. (00:17:00)
Continuity mistake: Jail cells have a rectangular slot with an outward flat extension for setting down food trays. The guard checks cells after "lights out" and there are no flat extensions for trays. (00:23:50 - 00:24:35)
Factual error: The movie is set in the Northern Great Plains of the United States, and the tribe is identified as Comanche, but the Comanche were located in the Southern Great Plains, across present-day northwestern Texas, eastern New Mexico, southeastern Colorado, southwestern Kansas, and western Oklahoma.
Continuity mistake: Although Adeline has her mouth to the ground (eating grass), her head is suddenly upright and still in a few views of Kay or Terry. The most noticeable sudden change in Adeline's head being upright occurs right after Adam hugs her. (00:34:34 - 00:35:00)
Character mistake: We see the lead driving on the motorway to get to the cottage. She leaves at junction 6 for Princes Risborough. Which means she is on the M40 that goes to Birmingham. When she arrives the host asks about the drive down and mentions the M4. This is a different road entirely, that goes to Swansea.
Continuity mistake: The time of day changes multiple times during the first half of the movie. When Danny is talking to Papi, Papi is outside and the sun is in the west indicating late day. In Danny's angle the sun is right overhead. There are multiple times when it is full on overcast in one angle and cloudless blue sky in the next.
Continuity mistake: When Harry wrapped Lily's ankle injury, there was bloody wrapping below the duct tape. When Karl asked to see Lily's leg, there was no blood showing on the material below the tape. Also, Harry did not completely cover the ankle injury with duct tape like he did to keep creatures from smelling the blood on Lily's stomach cut, questioning why the creatures could not smell the blood on Lily's ankle. (00:19:55 - 00:26:50)
Continuity mistake: Alan goes into his appointment with Dr. Fredericks at 5:08, and it is still 5:08 on the wall clock when he leaves her office. (00:10:20 - 00:14:03)
Factual error: Norma Jean's mother is driving away from the house onto the street. She turns left and crosses a yellow dividing lane in the middle of the street. It is supposed to be 1933. But these yellow dividers did not come into existence until the 1950's.
Continuity mistake: Riley puts the red hard-covered book and two others into the box, but puts the same books into the box when Gabby starts to help. (00:13:35)
Revealing mistake: Luke points a flashlight along the side of the staircase, but no shadows are produced on the wall from the vertical posts. Luke points the flashlight in front of himself and produces his shadow on the wall behind (and the shadow doesn't look like the way he is holding the flashlight). After Luke goes through the entryway aiming his flashlight ahead, a circle of light is behind him. The power is out, so the flashlight is the only light source - except that used for filming in the dark. (01:03:00 - 01:05:25)
Continuity mistake: During the time Sean and Kunle are talking to Bianca after class, Sean is wearing two gold necklaces but only the longer one is showing a few times. (00:04:30 - 00:05:41)
Continuity mistake: Marge had her left hand on a Win Fall ticket that (supposedly) was coming out of the printer on the side of the machine. Marge moved her hand away without removing the ticket. When the camera shifted, the ticket was not there. (00:54:10)
Continuity mistake: Jackie holds her pen as she takes notes. Next, her pen is set on the legal pad and her hands are on her lap (below the table and pen). The camera returns to Jackie, and she continues to hold the pen as she takes notes the whole time. (This allows for other questionable variations that could occur off-screen, if enough time.) (00:38:57 - 00:39:29)
Continuity mistake: Inside the building, Nina is at different distances from the man on the bench, ranging from about one body's width to a few widths away (while accounting for her limited movement). (00:15:15)
Continuity mistake: When The Artist is talking on the phone to Detective Mary Kelly, sometimes his long, wavy hair behind the phone is flat and other times fluffy (extending wider than the phone). (00:14:45)
Revealing mistake: When William and Jack open the door, enter the room, and walk past the helium-filled balloons (tied to a chair about 4' away), the balloons remain immobile. Due to how light helium balloons are, just opening the door or breathing nearby would be enough to cause the balloons to move somewhat - if they were actually there. (00:16:00)
Audio problem: When the boy and the leader of Iceland are hammering in posts and the boy is complaining that he's the heir and shouldn't have to do manual labor, there are at least two times when bad wind flutter in the microphones can be heard. It sounds like the wind clips the volume level and the audio briefly cuts out. It happens on windy film shoots, as wind screens can only prevent so much and its obviously very windy in this scene. Why this wasn't caught in post is hard to say. This is audible on the video on demand version.
Suggested correction: No such problem exists on the UHD/Blu-ray release. I also did not notice it on the VOD release, so it could have just been an issue with your sound setup.
Continuity mistake: When Maren and Lee are discussing their first time, Lee smokes a cigarette and removes it from his mouth, while still holding it in between his fingers. When the shot cuts to him saying "A rush", the cigarette is held at a different angle. (00:52:53)
