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.
Audio problem: During the party at the end of the film, the hand clapping and dancing drifts out significantly out of time and sync with the music.
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)
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 beginning of the movie, Miyoko has a drink in her hand while she frustrates the advances of her purple-sweatered coworker. Her grip on the chalice differs depending on the camera angle. (00:01:25)
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.
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 Frisson is giving the adder to the girls, the adder is going to go leave the jar through the hole but in the following shot, it is resting at the bottom.
Revealing mistake: As the guy is being pinned down by the giant hooks you can see for over a minute he can simply escape and slip his hands out. (00:52:30 - 00:53:30)
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 Umi is first descending the stairs in her house, her left hand clips through the left railing.
Visible crew/equipment: The two protagonists are on their tour bus, driving to the tourist pick-up spot. When they get there and get off the bus to greet the tourists, you can see in the shadows behind them the real driver shifting into neutral and trying to sneak out of the way. (00:05:35)
Factual error: Rochester Castle is seen standing alone and isolated from any other settlement. In actual fact it stands on the edge of the City of Rochester and very close to Rochester Cathedral, both of which certainly existed at this time.
Plot hole: When Sam first encounters Dan, the headmaster, Dan reveals that he had to quit his musical career when he impregnated and married a groupie, but that he loved his daughter. Later, Sam runs into Courtney behind a liquor store, and Courtney, who is actually Dan's above-mentioned daughter, discusses her "aggro older brother". If Dan's original error in timing resulted in a daughter, how could she have an older brother?
Continuity mistake: The licence plate of the Toyota Camry that Dagny Taggart is driving changes from a red Colorado plate to a Wyoming plate. (01:25:26 - 01:26:45)
