Continuity: In the extra/cut scenes included on the DVD, there is one where Rachel is in Katie's room snooping around. She goes over to the cabinet that has the TV on it and opens the top drawer, rummaging through it. After looking, she closes the BOTTOM drawer even though she was looking through the top one in the previous shot.

Continuity: When the horse breaks loose on the ferry it gallops down a narrow corridor towards Rachel to finally jump over the railing. When you look closely, especially at the car parked at the end, you see that the corridor changes in alternating shots. (Time) Submitted by Nancy<>Felix

Other: At the wake Rachel talks to some teenage friends of Katie's to find more about her death. The way they interrupt each other sounds very artificial, as one person stops talking in mid-sentence the split-second another person starts, without any overlap, e.g. when the boy butts in first. (Time) Submitted by Nancy<>Felix

Other: The skull they used for the little girl in the well is obviously an adult's skull.

Revealing: In the end, when we see the closeup of Samara's eye, you can see several white sheets used to reflect light into her face, as well as the reflection of the camera, in dead center of her pupil.

Continuity: When Noah drops Rachel off at the ferry and hands over Aidan's drawing it is pouring. However, only in close-ups of Rachel we see rain coming down in front of her face, but not when the camera shows Noah. (Time) Submitted by Nancy<>Felix

Continuity: At Katie's wake Rachel asks Katie's father if he's alright. When the camera angle changes the wine glass in front of him changes from oval to bulbous. (Time) Submitted by Nancy<>Felix

Factual error: In the scene where Rachel is walking in the street looking at the photos she has just collected from the photo-shop, her hands (and the rest of her body) are moving in the natural way. In the shot at the photos taken from behind her you can see the ground moving underneath her but her hands are perfectly stable suggesting she is standing on a moving platform.

Continuity: Naomi Watts' dark roots change length throughout the movie.

Factual error: The well in the video is situated on level ground. The Cabin under which it is now supposed to be has been constructed on inclined ground.

Continuity: In the first scene in Rachel's apartment Noah bites into an apple. First we hear him say 'ok' while he is still chewing but it doesn't sound as if there is something in his mouth, then he goes on talking after swallowing down everything, and finally we see him from behind, busily chewing again without having taken another bite.

Continuity: The scene where Aidan is waiting for his mother in the classroom starts with a close-up of his hand drawing a sun. From the way the rays are arranged we can tell that it's not the same drawing that's used in the later shots. Similarly, the picture his mother takes out of the folder later is not the same she is looking at when the camera angle changes. Also the way she holds it is different.

Continuity: At Katie's wake Aidan approaches her picture with a condolence book in front. There's a pen lying on the book with its tip pointing towards the picture. When he puts down his flower the tip is pointing at him. (Time) Submitted by Nancy<>Felix

Continuity: The knot of Aidan's tie is done in at least three different ways during Katie's wake: When he puts the flower down before Katie's picture, when he walks down the upstairs hallway, and when Rachel speaks to him in Katie's room. (Time) Submitted by Nancy<>Felix

Continuity: In the scene where Noah is being killed he is wearing sandals. In the scene where Rachel goes in to see him his sandles are gone. [In the interrim, Noah also happens to have been killed by an evil, psychic ghost and his body moved, supernaturally, to the chair. Samara, for whatever reason, would surely have been capable of taking off his sandles.]

Continuity: When Noah is at the supermarket buying cigarettes, he pulls out of his pocket a bunch of junk such as coins, trash, and an old pack of cigarettes and dumps it on the counter. In the next shot of the counter, all the junk is gone except for a coin, and the old pack of cigarettes.

Continuity: On the way to Shelter Mountain Inn Rachel is seen driving along a lake. The water is to her right, and the forest to her left. A helicopter shot confirms that, but when we see the car from the front the forest is to her right. (Time) Submitted by Nancy<>Felix

Continuity: When Rachel enters the reception at Shelter Mountain Inn the caretaker asks her to pick a card from a deck. She picks the nine of diamonds, but when she gives it back to the guy you get a blurred glimpse of the card, and it is a four of something. (That she finally agrees that the seven of spades is the right one is probably because she gets tired of the game.) (Time) Submitted by Nancy<>Felix

Continuity: When Rachel gets dressed for the wake the black brassiere under her white undershirt is sometimes visible, sometimes not. (Time) Submitted by Nancy<>Felix

Other: In the scene where Rachel is in the car and looking through the notebook, when she turns the page you see the letters KCUF (a certain word spelled backwards) as if it's written on the previous page. The actual word is hard to see when going forward, but I was able to see it easier while slowly rewinding.
