Continuity mistake: Cutthroat awakes and finds a guy tied up in a chair. After talking for a moment, a sound and light show up behind Cutthroat and he turns around. The side of his face is lit up when he does. It cuts to a different angle and now his face is not lit up. (00:03:30)
Visible crew/equipment: When Jack arrives with the shopping, a crew member in shorts is reflected on the glass. Clearly not Max.
Audio problem: In Notes II, Madame Giry voice is out of sync as she says,"Fear his fury.".
Factual error: The wolves in this movie must be some sort of mutant super wolf. North American Grey wolves are not lion sized killing machines. They are typically smaller, by weight, than an average German Shepherd.
Continuity mistake: When Lucy comes home at the beginning of the movie she quickly buttons the top of her dress. While eating dinner, it is open and then buttoned again between shots.
Continuity mistake: In the opening scene just before Victoria descends into the cave, she's wearing two headlights, the bigger one is on her right side and the smaller one is on her left side. In the next scene while she is talking to Josh, the position of those two headlights changed. (00:15:10)
Plot hole: The very last scene shows Mary building a wall, apparently in her belfry. But there should still be the original wall that Rose built, with the hole in it that Mary smashed in. By killing Rose / having killed Rose, she prevents further harm, but all effects that took place before that (also the building of the wall), should stay (like her scars). It is very unlikely Mary broke down the whole wall just to add another body. (01:28:25)
Other mistake: In the scene near the start as Will Atenton is being driven to his house by the property agent there is a close up of the car which shows a snow covered bonnet therefore the car would not have been driven very far as the engine was not warm.
Continuity mistake: When Paul is chasing Bozlovski at the port, he repeatedly shoots through his passenger side glass, destroying it. A few seconds later, the glass can be seen undamaged when both cars are banging each other.
Factual error: Mallory tells Florence that the school is in Cumbria. Cumbria didn't exist in 1921. It was created in 1974 from Cumberland, Westmorland and part of Lancashire.
Factual error: Danny Greene has a bomb placed in Shondor Birns' car. As Birns is waiting to cross the sidewalk, the pedestrian walk-don't walk sign is a modern digital sign, that was not around in 1975.
Continuity mistake: In the scene where Lily is hiding behind Thomas' computer desk, she uses her little Eiffel tower necklace to put inside the socket to short out the power. When she goes to put it in, you can see the computer is plugged in on the bottom socket. After a really quick cut scene, the computer is now plugged in on the top socket. (01:05:00)
Factual error: Colonel Meyer's promotions are listed in his SS ID card as Hauptmann, Oberstleutnant and Oberst. Since the SS used a different ranking system from the Wehrmacht, they should actually be Hauptsturmführer, Obersturmbannführer and Standartenführer.
Factual error: The young priest sees images of a red-eyed horse, but later, it is referred to as a mule, which looks much more like a donkey.
Continuity mistake: Three teen boys are abducted to be killed at the church. One breaks free and finds a weapons cache and dies in that room, while his killer dies outside that room. Soon after, the preacher and his wife find the dead church member, then look into the weapons room to see two of the teen boys dead, side by side. But the second hasn't been killed yet, and dies running away from the church later, shot by the the local sheriff by mistake. (00:40:40 - 00:48:00)
Suggested correction: The second boy, the one who got shot outside, was playing dead so the church members would leave him. It is not a mistake in the movie.
Revealing mistake: When Donovan witnesses a fatal traffic accident on a rainy night, he suffers a mild heart attack and collapses in the street. Although he's lying on his back, unprotected from the downpour, surrounded by rain striking the pavement in both foreground and background, closeups show that no rain strikes his face, his felt hat, or his clothing. (00:12:20 - 00:12:50)
Continuity mistake: At the end of the movie, the bloody handprint on the car changes entirely the second time it is shown. (02:02:45)
Visible crew/equipment: As Max opens the bathroom door on the plane, a reflection of the crew is visible in the door. (00:50:10)
Revealing mistake: When Anna's looking at her reflection in the mirror she starts rubbing her face vigorously. Look at her right cheek and you'll it's red before she rubs, result of multiple takes.
Plot hole: When the hikers heard the voice calling out for help, they were yelling "can anybody hear me" and "is anybody there" in English. Once they rescued her and they tried to talk to her, they said she didn't know any English.
