Audio problem: In Notes II, Madame Giry voice is out of sync as she says,"Fear his fury.".
Continuity mistake: J. Edgar takes his secretary-to-be on a date and tries to impress her by showing off his card system for cataloguing books in the Library of Congress. When he runs to the book shelves he brushes past an open book set up on a display stand - sitting on a sheet of glass. The glass moves when he touches it and hangs off the edge of the table. When he returns seconds later the glass is back in place, centered on the table. His date did not move; she was still standing where he left her a few feet away and they were the only two people in the Library.
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 the hurricane hits, you see the "Clearwater animal rescue" sign break apart. After the storm passes, the sign is complete again (albeit missing some letters) on the ground.
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)
Continuity mistake: In the scene where Margaret Thatcher is teaching her daughter Carol to drive, you see Margaret's window partially open but just as they near-hit the cyclist, her window is down just enough for her to stick her hand out but in the next shot its back to being partially open.
Continuity mistake: In the scene where Deputy Rose Gammon approaches the car with the body of Cindy Van Alden in it, the position of the car changes between shots. From within the police car, the car with the body is parked diagonally with the rear end in the road. From the long shot, the car is off the road and parallel to it.
Factual error: During scenes set in the early Noughties (one of Dex and Emma talking on a rooftop at night, and another of Dex crossing the river on a bus), modern buildings are shown on the skyline, including the Heron Tower (2009), the tallest building in the City at the time of filming, but it didn't exist at the time the scene is set.
Other mistake: When Oscar finds the business card under the swing, the narration doesn't match the writing on the flip side of the card.
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: 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)
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)
Deliberate mistake: The driver's side mirror would not be able to capture the view of the store that Monique is robbing - the mirror is slightly angled towards the rear of the car, plus Arthur's car is parked too close across the street. (00:00:33)
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.
Visible crew/equipment: While Maria Leon is talking in the corridor to the head of the house she is applying to, the tip of a microphone appears on the top of the picture. (00:11:10)
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)
Factual error: The car doors wouldn't protect Adam and the other police officers from being shot - they offer no protection against bullets.
Factual error: The tracks of the red-eyed horse in the snow are not tracks that could be made by a horse. A biped (a human) made the imprints in the snow.
