Continuity mistake: Alexander still had the mark/cut on his forehead, running vertically to the outer edge of his right eyebrow, when he found the "Mars" candy bar, but it was gone less than 30 seconds later (after he found the gun). The angle as well as its appearance (wider, longer, straighter, and more pronounced) of the mark/cut on his right cheek also changed. (00:02:20 - 00:03:26)
Continuity mistake: Vampires don't like sunlight, but when Nathan was walking toward Elaine, the sun was shining through the windows on him. When the camera shifted to Elaine, the curtains/blinds behind her were closed, which would not enable enough sunlight to penetrate into the room and onto Nathan like it did. When Nathan was sitting on his bed, the sun was shining on him again. (00:54:00 - 00:54:45)
Continuity mistake: Jim pushes down the corrupt cop to the floor, and his hat falls off. A shot later, it's back on.
Continuity mistake: Mia holds her doll's face next to hers, but the doll is not there when the camera shifts. The doll is to Mia's side on the bed, but instantly back next to her face. (This is independent of the times Mia moves her doll.) (00:02:25)
Continuity mistake: Danny's car is shown going over the cliff twice - before and after Danny shoots himself. Right before going over the first time, Danny is shown with his right hand on the steering wheel but the second time with his right hand on the rifle (which is pointed toward his neck). (00:32:22)
Continuity mistake: Views of Paul falling (pushed) down the stairs showed different positions from the top of the stairs, the landing, and from the downstairs floor. His back ended up on the landing with his legs bent and feet on the third step. (The form/size of the step itself was awkward - there wasn't enough room for Paul's whole foot.) A view from the top of the steps showed his left leg on the landing, bent with his foot under his right leg, which was on the step. A side view showed yet another position. (01:33:33)
Continuity mistake: Toward the end of the film, Hannah, who has had her face pummelled by one of the villains emerges from the creek having escaped the fire with only minor bruising on her face and a cut on the bridge of her nose. Immediately after that, they are rescued but her face is now deeply cut, both eyes are blackened and there is a deep gash on her cheek.
Continuity mistake: Whilst looking for the ship on the glacier, the team varies between 9 members to 6, then back to 8. (01:49:00 - 01:49:33)
Continuity mistake: The white gift box was placed on the car's hood near the passenger side front wheel indentation. When the female cop (Valerie) turned around, the box was at an angle, not parallel, to the indentation. (00:02:21)
Continuity mistake: As Batman is walking through Arkham, he passes the Riddler's cell. Riddler leans up against the glass of his door with his hands against the glass near his face and mouth. When the angle changes to behind Riddler, suddenly his hands and arms are down more to chest level with his right hand outstretched towards the side of the door. (00:07:02)
Continuity mistake: Sharyn's top sheet was messy and wrinkled underneath her while she was sitting on her bed, but the sheet was smoother and the top part was folded over/down after the doctor left and she returned from pounding on the door. (00:07:26 - 00:08:28)
Continuity mistake: Helen's slipper is at about a 45° angle toward the right of the screen when Miss Willoughby finds it. When Detective Jimmy shines his flashlight on the slipper, it is facing the opposite direction. The second time Jimmy shines the flashlight, the slipper is at a steeper angle. (01:00:33)
Continuity mistake: There is no barn to the left of MacMasters' house (otherwise, it would be visible from the front porch), but when Albert runs from the side of the porch into the open, there is a barn. When Britt got home, there was a barn but it was not where it would have been when Albert was running from Jed's gang. (00:09:10 - 00:10:18)
Continuity mistake: At the restaurant, the background varies a few times behind Beth and Jack seated at a table. When the background is blurred, a young man can be seen to the left behind Beth, but he is not there when the background is clear. (Despite the different camera angle, he should still be visible.) Instead, two men are seated at the bar counter or an elevated table and a woman behind them is facing the screen. (00:11:47 - 00:12:49)
Continuity mistake: When Fenn finds the doll in the tree trunk cavity, shadows are cast in several different (contradictory) directions. If Fenn's shadow was in front of him, he was walking west toward the dead tree; north would be to his right. Examples: The tree's trunk and one branch were casting shadows to the south moments earlier and Geary and the tree were casting shadows to the northwest a little later. Geary's shadow was cast westward when Fenn took his photo with the doll. (00:04:28 - 00:06:47)
Continuity mistake: When Mrs. Chen tells Anne that she broke Eddie's heart, Michelle Williams' hair goes from the front to the back of her shoulders. (00:59:15)
Continuity mistake: When Billy is walking (from his front porch) to his Jeep, the ground is brown, and he has to take several steps to reach the cargo area. When the camera shifts to a front view of Billy by the driver's side door, and he says, "Hi, coach", the Jeep is parked too close to the house for Billy to have taken that many steps to reach it and the grass behind the Jeep is green (not brown). (00:07:45)
Continuity mistake: Ed Harris plays a property manager character and is featured in the beginning of the movie, walking with a pronounced limp, a seemingly painful gait. His character is shown in many other nominal scenes throughout the movie without limping. Most notable, shortly before the end of the movie, his character is shown dancing wildly, spastically, and jumping to music, seemingly unencumbered and fluidly, in a way that his character in the first part of the movie would not have been capable of doing.
Continuity mistake: The rope to pull the kid's sled was largely caught underneath the front of the sled when the "kid" started riding down the hill, but almost all the rope was on top of the sled moments later. Also, the rope getting entangled under the sled should have interfered with gliding in the snow and possibly caused an accident/injury. (00:02:42)
