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)
Factual error: The movie takes place in Stamford Connecticut (per locations and is shown on cop cars). Eva buys a bottle of wine in a supermarket, but in CT only beer can be purchased in a supermarket. (00:25:15)
Audio problem: In Notes II, Madame Giry voice is out of sync as she says,"Fear his fury.".
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.
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: 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.
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)
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)
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.
Other mistake: Spoiler alert! At the end, when the sniper shoots the killer, Eve says he is 800 yards away, but within the next 30 seconds he appears at the scene. (01:22:02 - 01:22:32)
Other mistake: At the beginning, the arrival board has the cities listed in alphabetical order, but "San Francisco" comes after "San Jose" when it should come before it.
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.
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: 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.
Other mistake: Danny meets the union muscle in the machine shop at midnight, but it's broad daylight as the sun is coming through the windows. (00:13:40)
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.
