Continuity mistake: When Jessie and Carlos walk to the church ruins, a big bruise on his nose suddenly appears for a couple of seconds, only to disappear briefly after.
Continuity mistake: During the sex scene between Milo Ventimiglia and Lauren Lee Smith, in which the fat guy was found dead, three consecutive shots showed that Milo Ventimiglia has his shirt on on the first, then the shirt disappeared on the next, only to reappear on Milo Ventimiglia's body again in the third shot.
Plot hole: At the end of the movie we discover that the main character (Claire) was in the plane crash and was sitting next to Eric as the plane started to go down. However at the beginning of the movie( before we are supposed to know Claire was in the crash) Eric can be seen but Claire is not next to him. (00:01:10 - 01:19:20)
Character mistake: During the seminar, Professor Rohl tells students that only 19 workers of Auschwitz were sentenced (in 1966). During the first trial of Nazis from Auschwitz, 39 were sentenced, including 23 persons condemned to death. The trial was in 1947 in Krakow.
Plot hole: Blackbird and Ritchie fake their deaths in order to lure Wayne and Carmen out of hiding. What was the point of pursuing Wayne and Carmen? The only reason they wanted the couple dead was to prevent them from testifying. The problem is .if Blackbird and Ritchie were "dead", the case would be CLOSED. Carmen and Wayne wouldn't be testifying anyway. So why go to the trouble of killing them? It makes no sense.
Continuity mistake: When Ronald's girlfriend gets up at the breakfast table, and tousles his hair, Ronald is holding a glass of milk in his right hand. There's a cut to a wide shot, and Ronald is not holding the milk. There's not enough time for him to have put it down.
Factual error: The bar shown in Iqualuit is not real. Iqualuit only has 6100 or so people, and there is no bar like the one shown in the movie. The building is wrong - it doesn't even look like any buildings in Iqualuit. There is one bar that looks nothing like the movie, one Legion, and a bar in the hotel in Iqualuit.
Continuity mistake: Joe is talking about the second target with Kong. Kong is eating noodles while Joe triggers the lighter; in the close-up, Kong's hand is at a different angle. (00:32:25)
Continuity mistake: Mike Manador watches his girlfriend Gina drive away in a taxi. Behind him a truck can be seen coming down the street. Mike then steps out into street seconds later, but the truck has vanished. Next shot looks up the street and sure there is the taxi but no other vehicles, and you can see the entire street. (01:41:25)
Continuity mistake: When the mother puts the drawing from her daughter in her pocket she puts it in the left pocket of her jeans. When she takes it out later, she takes it from her right jean pocket.
Continuity mistake: Gina's father opens the door, club in his hand, and finds his family inside for the surprise party. In the reverse shot, Gina's position is also mirrored, having the right arm raised instead of her left. (00:08:15)
Other mistake: Jon's vehicle does not have the front license plate that is required in California. (00:57:23)
Continuity mistake: When we first see Agent Holloway viewing the crime scene photos taped to the wall, he is facing camera looking at transparent pictures on a transparent wall (as if we are behind that wall, seeing through it). When the angle changes to see the Agent from behind, the photos are now paper photos on a normal, opaque wall and the pictures are arranged somewhat differently - most notably to Holloway's right near the top where two wider photos are vertically aligned atop and below each other in the second shot when they were misaligned in the first shot by nearly half their width. The transparency versus opaque materials issue is a stylistic choice of the director and not a mistake, but the mismatched alignments is a mistake. (00:11:25)
Factual error: During the opening credits. An LCD screen is shown with lat/long coordinates. The movie takes place in the Persian Gulf. The coordinates are in the vicinity of Oceanside, CA.
Continuity mistake: When the first guy out of the main 3 is dragged to the hunting range (after having his spine exposed and meat cut off), he falls backwards into the snow and when he sort of rolls over, there is snow all over his exposed backbone and flesh but when he stumbles and gets up, there is no evidence of snow whatsoever.
