Continuity mistake: The pile of clothes Lea took out of the dryer and placed on the table were rearranged differently when the camera shifted to the opposite side. (00:41:52)
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: 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)
Continuity mistake: Finley carried her violin and one square suitcase out of her room to go to her audition. Sean parked at Dublin Airport and removed Finley's luggage from his trunk - two rectangular suitcases, neither matching the one Finley had. (01:44:25 - 01:45:21)
Continuity mistake: Joe has 'Rick C' (his partner) listed as a contact in his phone - late on in the movie when Joe calls him from the bathroom stall, he is listed as just "Rick"
Continuity mistake: After her sister hangs up on her, Sue repeats in front of the mirror the self-help audio mantra. She suddenly holds the receiver in front of her chest higher than in the previous shot. (00:04:10)
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: 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.
