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: When Eddie Murphy's assistant makes assumptions about why Jack isn't speaking, he throws his notepad down and has empty hands as Jack pushes him out of the office. When the angle changes, he has a notepad in his right hand.
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)
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.
Other mistake: The news anchor in the opening scene noticeably flubs her lines at one point.
Other mistake: When Emma Watson says "get wasted all the time", her British accent is very obvious, especially when she says "all."
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)
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)
Visible crew/equipment: At the end of the movie when Sparkle is on stage singing in her red dress, a camera shot pans upward toward the ceiling on the stage. There is a cameraman backstage walking on a rafter or something, trying to run so as to not get caught on film, but fails.
Visible crew/equipment: When the 2 bad guys get the car you can see the 2 cameramen reflected in the car door. (01:10:00)
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)
Continuity mistake: When the form falls onto the girl's face, the position of the form changes between shots. (00:00:35)
