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.
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)
Continuity mistake: While he is copulating with Laurence, François Monge receives a phone call from his boss about the murder case in Bobigny. To shush his vocal partner, he gives her a slap on the shoulder, but he does it with the right hand in the view from behind, and the left hand in the full frontal. (00:08:55)
Character mistake: It's said in the movie a vice presidential candidate never gave a concession speech. Geraldine Ferraro did this in 1984.
Continuity mistake: In the middle of the film, the girl scouts and the leader are having a juice break and in walks the love interest (the father of one of the scouts). In the shot where the leader walks towards the love interest, the way she carries her glass of juice changes from the top to the side.
Revealing mistake: Lazy prop department at work in the opening credits of this movie; look at the guest list. The second page and the first page are an exact copy and paste of the same names and addresses. (00:01:35)
Continuity mistake: Dinner at Forestier's home, and Georges Duroy does not know which knife to use to eat. The asparagi in his plate are across the small pie in the wide shot, and in close-up they are arranged entirely on the side without his intervention. (00:08:20)
Continuity mistake: During the scene where Daniella and Clay are enjoying a glass of wine together and she is revealing how much she knows about him, Daniella's left hand/arm positions change continually throughout the shots, from on the chair arm to playing with her hair/alongside her face.
Factual error: The Life One spacecraft is hit by a micrometeoroid. Sparks are to fly, among other effects. The sparks are bifurcated, meaning they were produced by using a grinder, not by a micrometeoroid collision.
Continuity mistake: When Jeremy and the cop girl are shooting for practice, the amount of cans changes between shots.
Continuity mistake: After Mike has set the tent up they go for a ride on their snowmobile to check the scenery out. They come uphill parking the snowmobile facing upwards. They get up looking at the scenery, and a few shots later the snowmobile has suddenly turned 180 degrees facing downhill. (00:13:40)
Continuity mistake: When Luke grabs a beer from the mini bar in the hotel, there's a lot of beer foam in the top of the bottle. In the next shot, when Luke's sitting on the bed, the foam is gone without taking a first sip.
