Continuity mistake: In the scene where Tom is tasting wedding cakes he is sitting at a table with a blue box cake with white bow, but in the next shot a lady then places the cake on the table.
Continuity mistake: In the scene where Joaquin Phoenix's character is walking between a heavily wood-paneled wall and a window and banging on them: The first time he bangs on the paneling, one of the panels appears to split and swivel up showing white underneath. The camera briefly changes angles. When the camera returns to Joaquin Phoenix, the split panel is fixed.
Continuity mistake: Eden's hand and arm positions change between shots during the final scene in the movie, when she is kissing Adam.
Continuity mistake: When the Wolverines are attempting to get "the box", the Matt Eckert character is shooting through a window. When we see his point of view, there are blinds in the way of the camera, however every time it shows the actor, the blinds are open.
Audio problem: When Emily picks up the tooth from the box, she says "ew" but if you look in the mirror her lips don't move.
Continuity mistake: In the very beginning, the truck that hits the vehicle does so from straight behind. However, when they pan out, someone the truck is perpendicular to the crashed car. The snow tracks don't show the car that was hit swerving, and there aren't any tracks to show that the truck reversed either.
Factual error: The movie is set in the current time (2012), but Andy flies in an L1011 in the distinctive paint scheme of Delta Air Lines. Delta retired the last of their L1011 fleet in 2001.
Factual error: In one scene Drew Barrymore stands in from of a political world map, showing the political borders as of today. You can see the successor countries of the Soviet Union in that map. But the plot plays back in 1988, with the Soviet Union still alive.
Other mistake: When Christine is shot near the end of the film, there's no blood on her dress or the Phantom's hands.
Visible crew/equipment: When searching the basement, as the character goes through a doorway, the camera is reflected on the left hand door frame. (01:13:10)
Revealing mistake: When Ray reminisces about having fought the Germans in WW2, a flashback is shown with him fighting in a bunker. He is carrying a No.4 Lee-Enfield rifle which requires the bolt to be worked after every shot to reload. However, he is shown firing two shots in rapid succession without moving his hands at all, revealing the shots to just be flashes added after filming.
Continuity mistake: The objects on the desk at Lax's interview with Herman change several times. Sometimes, the tripod is closer to the center of the desk, about a foot away from the file folder, but other times it is closer to where Lax is sitting and one leg is almost touching the folder. The angle of the file folder and distance to the edge of the desk also varies. The Styrofoam cup switches from one side of the desk to the other. (00:17:07 - 00:18:20)
Revealing mistake: In the opening scene, Johnny and Hickey sit in the front seat of a car. Views out the side windows blur, there is a gray background behind Johnny instead of the rear window, and when Hickey holds the cross toward the windshield, the "outside" is all grayish-white. At one point, there is light on Johnny's right forehead, cutting diagonally downward (too linear to be the sun), and another time, there is light behind Hickey on his headrest. (00:00:31 - 00:03:30)
Factual error: On the Yorkshire Post front page it says "Monday 7th March 1974", but that was a Thursday.
Continuity mistake: The German and British airmen are looking at the Northern lights. From the rear the men are apart, but the front shots of them show them much closer to each other.
Continuity mistake: At the "written by" screen with Al Pacino and Christopher Walken meeting, the shadows of the building run perfectly parallel to the fence and through the whole length as far as it can be seen. The two exchange 30 seconds of dialogue and an awkward hug, and drive off. The shadows have changed entirely; they start about halfway at the gate, with an oblique angle. (00:04:05)
Continuity mistake: Throughout the film, John Travolta's hair changes back and forth and back and forth from being really really really short to just really short.
Continuity mistake: Alexandre Lagarde puts his fork into the plate of the attractive client, much to the scorn of her husband. The morsel in close-up and the one she actually puts in her mouth are different. (00:06:10)
Continuity mistake: When the mean Santa puts the little girl in his lap and asks her what she wants, she's wearing gloves. When it cuts to a different angle, suddenly her gloves are gone.
Continuity mistake: Celeste's white Honda (Alabama plate #LF8VN3D) is riddled with bullets right after she drives up to the cabin, but there aren't any bullet holes later after the police show up. (01:26:00 - 01:45:00)
