Visible crew/equipment: In the shot where Faris is running to Evans's room to get him away from his one-night stand, as she passes the staircase you can see a shadow with movements that don't coincide with those of Faris. Deductive logic can be used to determine that this shadow is that of a member of the crew.
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 Alan is taunting Michael about selling door knobs and Michael's back is against the door frame to the dining room, the dining room is dark; both chandeliers are off. All four characters are in the living room but as Michael responds to Alan's taunts, the lights are on, even though no one entered that room and Michael's hands were in his pockets during the exchange.
Continuity mistake: Three-quarters into the film, Jacob brings Rosie, the elephant, to Reece Witherspoon's tent. Her husband, August, appears and seconds later there is, out of the blue, a cigarette between his fingers.
Continuity mistake: When Conan first fights Remo, Conan places a blood stain on his forehead by pressing his sword to it. Remo then runs off, and Conan gives chase immediately, pausing only to get Tamara on his horse. The stain is still there when Conan mounts his horse. The next time we see them, Conan and Tamara is still chasing Remo, but now Conan's face is completely clean. It is highly unlikely he would pause in pursuit of one of his father's killers to wash his face. (00:47:55)
Factual error: The security guard in the bank is carrying a revolver as a sidearm but has semi-automatic magazine pouches on his duty belt.
Continuity mistake: Mariso Golfetto is beginning a tirade about immigrants and assaults on women. A woman gets her drink from the barman, picking it up with her right hand, completing the movement. Reverse shot, and not only she repeats the gesture and still needs to pick up the glass, but she does it with her left hand. (00:07:00)
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)
Continuity mistake: In the 'match' when he tags with John Cena, Fred is picked up by the rival vampire in a fireman's carry position (kinda like for Cena's Attitude Adjustment), but his head is over the opponent's right shoulder in the first, wide, shot and towards the left shoulder in close-up.
Continuity mistake: Realizing they are missing the necklace, the three girls get on the balcony looking for Riley and staring at the clock. When she says "At noon", Meg is leaning on the railing with the side of her hand, but her hand is in frame in the following shot, flat on the palm. (01:16:20)
Revealing mistake: While Lynn is driving, the scenery outside the driver's side window goes white a few times and, other times, with intermittent specks of green tree leaves/shrubs. The white-outs are too low to be representing the sky. For a period of time, the lower third or so of her side window is a horizontal white bar. (00:02:20 - 00:03:38)
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.
Continuity mistake: At the start of the film, when the bus driver helps the man in a wheelchair onto the bus, his hat disappears then reappears. (00:05:00 - 00:06:00)
Continuity mistake: When Anna starts to open the balcony door in the hotel room she stubs her finger and Jake tends to her. The balcony door is only open slightly, with them standing in front of it. In the next shot the door is open about half way with both Anna and Jake standing on the other side of it. (00:16:25)
Factual error: When Andy is headed to Mr. Simon's house, a white 90s Lincoln Town Car can been seen in the background, out of place for the 1965 setting. (01:31:45)
Visible crew/equipment: During the torture and murder of Troy there is a moment when Jamie, unable to watch the violence, sits in the kitchen with accomplice Mark Haydon. Jamie and Mark sit in silence at the kitchen table and the film cuts between close-ups of them. In the two close-up's of Mark you can see the boom microphone reflected in the glass of the kitchen cabinet near his head. This happens twice and the microphone lingers both times. (01:15:29)
Other mistake: When the captive begins her escape, she kicks the bed through the orange portal offscreen, but the portal only starts about a foot off the ground, so the bed would have hit the wall, rather than have gone through the portal.
Deliberate mistake: When C-3PO, R2-D2 and the younglings are driving through the battle zone, Anakin Skywalker and General Grevious can be seen battling. Later, Darth Vader can be seen on Hoth. This would be impossible due to Anakin Skywalker being Darth Vader. (00:08:50 - 00:12:20)
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.
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)
