Factual error: As well as the sergeant's stripes on his cuff, Sergeant O'Neil wears three pips on his epaulettes, which would indicate a much more senior rank and would not be worn together with the stripes.
Continuity mistake: After the wolves have killed the guy poorly sniping them at the old encampment location, Clair Hamilton glares at Larsen from her sitting position and moves towards him to ask more about what he just said about Father. During this sequence, Gina Carano's hat is burdened by a bit of snow or practically no snow at all, back and forth with no logic between cuts. (00:35:50)
Continuity mistake: When Ana finally escapes in Peter's truck, the truck is a Nissan Frontier extended cab with a long bed, no tonneau cover and no roof rack, but shortly after they show her crossing a bridge in a Frontier crew cab (4 door) short bed with a tonneau cover and a roof rack. It is also has dirt on the side that looks like road salt whereas the original truck was very clean. (01:16:00)
Factual error: Eve Curie is shown as having been born before the Curies are nominated for the Nobel Prize in physics, which they eventually won in 1903. However, Even Curie wasn't born until December 6th, 1904.
Continuity mistake: Right after the scene where Nels saws up his gun, he walks into a store with his arms folded. His hands are down close to his stomach. When it cuts to the next angle, they are much higher at his chest. (00:26:51)
Character mistake: It's merely training, but her opponents are hostile and want to exclude her from playing, so it's funny then that they don't call Kim out for her actions being egregious fouls; she brings the ball trapping it between her feet in multiple cartwheels (you can't just hold the ball between your feet for prolonged amount of times and 'carry' it). You could also say she kicks the ball at an opponent's face on purpose, which is equally unsporting. (00:24:00)
Continuity mistake: After the kids are told Sara hung herself at the hospital, Chuck asks "what are they waiting for, let's go". Stella is bending down to pick up the book in one shot, but the angle cuts while Chuck is still saying the word "go" and suddenly he has vanished from the room as the other two start to leave.
Factual error: The scenes set at Wrestlemania XXX (2014) were filmed at a RAW show in 2018 - fans are visible in the background wearing wrestling merchandise more recent than 2014.
Character mistake: Detective Spitzer went into Harper's dark/unlit house, saw his partner Greg on the floor, and then saw Alec standing in the kitchen. Without identifying himself, telling Alec to drop his weapon (pistol pointed toward the floor), or bothering to determine what happened, Detective Spitzky shoots Alec. (01:27:08)
Continuity mistake: After Brandon finds out he arrived in the alien craft, he walks outside in the rain where he finally translates "Take The World" as his purpose. He continues on to Caitlyn's house to tell her what he has discovered and to give her a flower. When he arrives in her room, he is completely dry.
Revealing mistake: At the start when they're clearing the White House field Little Rock shoots her gun without her finger on the trigger. (00:04:20)
Factual error: The USA map is inaccurate for the year it is set in. It shows all states but in 1886, many of the northwest states (e.g. Montana, Idaho, the Dakotas) weren't states until 1889+.
Revealing mistake: Mazhar is saved by Raghu who with his amazing strength pulls the chains tied to the tankers and breaks free. The chains supposedly pulled by the powerful trucks though are not in tension. (00:08:50)
Character mistake: Toward the end of the film, Detective Davis orders Captain McKenna to put his badge on the table. New York City police always refer to their "shields", not badges.
Other mistake: The movie is said to be set one year after receiving Annabelle, but the music box from The Conjuring is on the shelf. Judy in The Conjuring is an 8, possibly 9 year old whereas in this film she celebrates her 10th birthday. If Annabelle Comes Home" is only 1 year after obtaining the doll (2 years prior to The Conjuring timeline) then Judy would not be turning 10 years old; she essentially lost a few years of life rather than vice versa.
Continuity mistake: The new Bosley goes for a hug after reporting Edgar's demise. You can see as the hug begins that the sunglasses are not in Elizabeth Banks ' left hand, but it's where they end up when she says that "hugs work." (00:27:50)
Continuity mistake: Alan and Marie are chatting with the doctor after the initial sonogram. Marie's hands change position few times between shots - for instance right after the "crack" joke, she lowers her hand but it's on top of her pregnant belly at the cut. (00:03:30)
Continuity mistake: When Lance is telling the guard at the start that he's going to throw his gun to the snowman behind them, the snowman that is there was not there in a previous shot and appeared from nothing.
Continuity mistake: The plate on the vehicle (Silver Mustang - IV6866R), appears in one scene and disappears in the next. (01:21:10)
Continuity mistake: Dr. Stone mentions there is an emergency exit below the landing pad. He then asks the pilot if there is a camera underneath. In this shot, the pilot has his eyes partly closed and his lips pursed together. It cuts to a close up of him and suddenly his expression is different, with his eyes wider open and his mouth open. (00:19:50)
