Revealing mistake: After Katie pulls the TV plug she tries to find Becca. When we see her from upstairs there's a reflection on the floor next to her that can only come from a ceiling light. However, there's no light falling on her. (00:06:30)
Continuity mistake: 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. (00:07:20 - 00:09:05)
Continuity mistake: When Rachel gets dressed for the wake the black brassiere under her white undershirt is sometimes visible, sometimes not. (00:11:55)
Continuity mistake: 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. (00:12:35)
Continuity mistake: 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. (00:12:45)
Continuity mistake: 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. (00:20:45)
Continuity mistake: 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.) (00:21:15)
Continuity mistake: After Noah sees the video at Rachel's place he joins her on the balcony. His hair is hanging over his face but when they go back in it's combed back. (00:29:20)
Continuity mistake: 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. (00:29:30)
Revealing mistake: During her research on the video tape Rachel comes across a picture of Anna Morgan drinking champagne with some friends. It's quite obvious that her picture has been copied in. (00:41:25)
Revealing mistake: When Rachel searches online for "Moesko Island," you can see in the address bar of the browser that she is really looking at local files (C:\WIN98\Desktop\search.com\... etc). (00:42:30)
Continuity mistake: When Aidan and Noah are talking in the car, outside of Katie's house, Aidan is coloring on a blue lap tray. When Rachael comes to get him out of the car a couple of minutes later the lap tray is now green. (00:51:25 - 00:53:10)
Continuity mistake: 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. (00:52:45)
Suggested correction: You actually can see the rain falling when the camera is on Noah. It just isn't as noticeable because of the lighting. It's similar to if you look outside during a rainstorm at night and you can't see the rainfall that well unless you are looking at a street light or porch light.
Continuity mistake: 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. (00:55:35)
Continuity mistake: In the shot of the horse jumping off the ferry, the ferry's name "Quinault Seattle WA" is seen on its side. Rachel looks down at the horse in the water from the same place it jumped, but the appearance of the ferry's name is now different, namely the position of the two words "Seattle" and "Quinault" are now flush with each other when they were not before. (00:55:40)
Continuity mistake: When Rachel first meets Richard Morgan during their conversation, Richard's jumper and collar are green in some shots, but blue in others; it's very noticeable as he opens the cupboard and cleans his shoes. (00:59:30 - 01:02:30)
Continuity mistake: After breaking into the records room, Noah is looking at Samara's pictures or photo negatives, holding them up to the light, the shot of him show his fingers covering some of the first picture, but the next shot from his point of view the whole picture is visible and his fingers cannot be seen. (01:04:25)
Continuity mistake: When Rachel lifts Samara out of the water in the well, Samara's hair changes position from shot to shot. First there is no hair on her face at all, then there's some draped across her neck and down the side of her face (which Rachel moves), and finally when Samara "decomposes", the hair across her neck is gone as well. (01:33:00)
Visible crew/equipment: When Noah and Rachel get back home to Aiden and Noah picks him up you can see a crew member's silhouette in front of a window. (01:36:44)
Continuity mistake: After Noah is killed by Samara, Rachel comes in. She steps up to the chair Noah sits in, looking away from her. She rotates the chair counterclockwise to look at him. We don't see his face yet. We do see it near the end when Rachel has a flashback. For a split second, Noah's face is revealed in the chair now rotating clockwise. It should have been turning the other way around. (01:43:40 - 01:46:05)
