Continuity mistake: When Jake enters the living room to bring the drinks to Emily, the magazine and remote sitting on top of the two books moves between shots. (00:01:35)
Continuity mistake: At the beginning of the movie when Jake sits down next to Emily with a bottle of drink and two empty glasses, after he sets them down on the table the two glasses are suddenly filled with drink, instantly between shots. (00:01:50)
Visible crew/equipment: In the shot of Rachel driving up the street with Aidan just before they arrive at their new house, the car breaks right in front of the camera for a few seconds. In this shot you can clearly see the camera reflected in the left corner of the car. (00:07:15)
Continuity mistake: Near the beginning, Hayden is sitting at the desk in his room and his shirt collar is wide open. His neck shows, but that's it. A moment later, when he leaves his room, and comes into the Kitchen, he wears a light grey t-shirt under the other shirt. (00:09:05)
Continuity mistake: After Aidan comes downstairs and sits at the table for dinner, he is flicking through his photography folder. In the shot when Rachel walks away from him and goes back to the oven, there is no plate at Aidan's placemat, yet it is there in every other shot before and after. His drink also moves without him touching it. (00:09:05)
Continuity mistake: When Rachel is talking to Aidan at dinner, the position of her hair changes a few times. In one shot she pushes her hair behind her right ear, yet in the next shot her hair is pushed behind her left ear instead. (00:09:50)
Factual error: The Daily Astorian office where Rachel works has the Columbia River in the background, however the real Daily Astorian office is located well off the waterfront. (00:10:15)
Continuity mistake: When Rachel is working in her office and Max comes in to talk to her, during the scene the direction that the coffee mugs handle faces (on Rachel's desk) keeps changing. (00:11:00)
Visible crew/equipment: When Rachel pulls up to the crime scene where Jake was killed, as she gets out of the car you can see a grid of set lights reflected in the car window door. (00:12:30)
Continuity mistake: When Rachel is trying to get Emily to speak to her at the police station, near the end of her attempt the shots alternate from closeups to wider views. In the closeups, Emily's hair is very messy and tangled but in wider views it is much neater and straightened. (00:16:35)
Continuity mistake: When Rachel is burning the videotape in the canister out in the field, she throws the tape on the fire with all of the reel pulled out and sitting on top of the case. In the next shot the reel is no longer visible on top of the video. (00:19:30)
Continuity mistake: When Aidan is in the bathroom at the fair, he turns a faucet and then he walks across and turns another. After turning the second one, the faucet changes position from the wide view to the closeup, evident by the ridges on it. (00:27:45)
Audio problem: When the deer are all grunting at Rachel and Aidan, the whistle of an elk can be heard despite the fact there are no elk in the scene. (00:30:40)
Continuity mistake: When Rachel begins to brake her car after seeing the deer on the road, as the shots keep changing the markings on the road also keep changing. In overhead shots the markings are a single broken yellow line, but in closeups of the wheels, the markings are solid double yellow lines. (00:30:40)
Continuity mistake: When Rachel finds Aidan standing at his bedroom wall and the image of a tree begins to burn in the wallpaper, she runs over and tries to pull him away. As she does this, the globe sitting on the desk beside them rotates itself between shots. (00:35:45)
Continuity mistake: When Rachel is talking to Aidan at her Daily Astorian office, when she asks him if he knows why Samara is back, she puts her hand on his face. In the very next shot it's down in her lap. (00:37:05)
Continuity mistake: When Rachel is tucking Aidan into the bed at Max's house she puts a red blanket on him and then a brown blanket on top. Then during the next shots the red blanket goes from slightly visible to completely covered by the brown one and back again to being slightly visible. (00:39:15)
Continuity mistake: As Rachel is trying to get Aidan to get in the bath at Max's house, she removes the blue towel from him and throws it on the towel- rack. Then during the rest of the bathroom scene, everytime we see the blue towel in shot it is in a different position each time. (00:39:55 - 00:46:35)
Continuity mistake: During the scene where Rachel puts Aidan into the bathtub at Max's house, he is wearing very light white boxer underwear as he is being put into the water. A little while later when Rachel pulls Aidan out of the bathwater, he is suddenly wearing very dark blue/navy colored boxers. Although water would darken the color somewhat, this is far too dramatic a change to be natural. The lighter color couldn't have possibly darkened to that extent. They are two different pairs of boxers. (00:41:55 - 00:48:10)
Continuity mistake: When the deer attack the car, the first deer hits the car, and he shatters the driver's side window. In the next cut, you can see Rachel's reflection in the recently shattered window. (00:43:52 - 00:44:20)
Answer: The deer were attacking the car because Aiden was in the car. Aiden was possed by Samara at the time and Samara makes animals go crazy.
