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.
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: 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.
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.
Continuity mistake: When the guy with the hat plays pool and goes to hit the blue ball, in the next shot it changes to white and he completely miscues. (00:27:25)
Factual error: In the scene where Robert Redford is hiding in his car in dealer's lot, the FBI say they have him tracked and located, "Got him. Just off I-94 near Gurnee, IL." Redford may be in Gurnee, but the local police speeding to catch him are not: The area around Gurnee is flat as a pancake, yet the police drive by many tall hills and/or small mountains. (01:09:00)
Continuity mistake: In the parking garage scene, when Lindsay initially parks the sign states "Reserved For Walter Deeds." When being towed his name on the sign disappears. (00:06:30 - 00:10:45)
Other mistake: During the end credits, there's a misspelling. An 's' is missing from 'First Assitant Camera'. (01:33:05)
Factual error: Close up, very detailed footage of a Cobra citizens band radio is used for the scenes where dispatch radio traffic is coming over the police radio. Police dispatch does not, nor has it ever, used the Citizen's Band radio service. (00:11:25)
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.
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: Sheila is clutching the phone to her chest with both hands, since Melinda is reaching for it to delete the butt-flexing video. The door chimes and the bearded man enters the store; in the foreground Sheila is in a different position with her arms crossed, and in a third one with her arms down at the next cut. And even more noticeable, a 4th different one as she walks away, holding the phone across the chest to the opposite side of her body all of a sudden. (00:07:50)
Factual error: Kuklinski is looking at a newspaper which is dated January 3rd 1983, and the text reads that Roy DeMeo was found dead the previous day. In actuality, Roy DeMeo died on January 10th 1983. (01:22:55)
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: The position of Beth's truck facing her motel room (106 or 706?) changes during the time she is talking to Holly. Sometimes the truck is closer to the room next to hers (105 or 705) and to where Beth is standing. Also, the truck's front tires are different distances from the curb. (00:48:25)
