Revealing: In the scene when the main character is in the library on the internet, she goes to a couple of websites. When the shot shows the URL up top, it is C:\windows98\mydocuments\etc.html. Instead of actually searching on the web they used a premade html page and accessed it from their computer. It's simple enough to just not display the address bar in your browser, so I don't know why they let this one slip through...

Other: For some reason, there is no "correct entry" option. I thought I'd do it like this. The well extends above the ground some feet. It is mostly in an open field: therefore, no shade cast upon it. As long as the top surface of the well is not PERFECTLY flat and the bottom surface of the cover is not perfectly flat, there will be gaps that light can enter all the way around. You can experiment with a tube of any kind and a lid to fit. Just rough up both surfaces. Place the tube over one eye, close the other, point the tube to the light and slide the lid on. You will see a ring.

Visible crew/equipment: In the scene where Noah breaks into the mental institution's record room and is looking through Anna's files, there is a visible arm with a blue sleeve to his right, even though he is alone.

Continuity: Samara, as seen in the psychiatric sessions on the videotape, has a prominent gap in her front teeth - yet when she decomposes in Rachel's arms down in the well, the skull that is left has perfect teeth with no visible gap.

Factual error: In the scene where Noah analyses the tape, he says that the 'timecode' seems to be invalid and says that every tape has a track where you can see what device was used to record it, etc. The video technology explanation originates from the original, Ringu, with the plot of The Ring changed to make it more applicable to average Americans. But a VHS tape does not have a special track for timecode. It is possible to lay a timecode onto the tape in either an analogue form via a special audio channel, or as digital information on lines 16 and 18 of the vertical interval. But this 'timecode' is only used for professional video editing. A standard VCR, like the one they were playing the tape on, does not use this, and therefore makes Noah's explanation a minute of utter nonsense.

Visible crew/equipment: In the scene where Noah picks up Aidan from the floor, you can see a crewmember in the shadows up the stairs when they are going into the next room.

Continuity: 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.

Continuity: In the scene where Rachel bursts into Noah's apartment after he was killed, play it slow-motion when she flips the chair around. You can see up to half of his normal face & hair, with no decomposition visible, or hair loss.

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.

Deliberate "mistake": When Noah drops Rachel off at the ferry he drives right up the the gate at the dock which is strictly prohibited by Washington State Ferries. The only cars allowed in this area are the ones who are boarding the boat, no exceptions.

Continuity: 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.

Revealing: 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.

Factual error: The license plate on Rachel's car is not a valid Washington State license plate, while similar to the very outdated original issue plates, which would have never been issued on such a new car, they are missing tabs on the front which were mandatory on those plates and all Washington plates in 2002 when the movie was filmed.

Revealing: When Rachel is racing to save Noah, she is trying to call him on her cell phone. There is a shot of two hands on the steering wheel as the car turns and then a cut to her holding the phone in one hand a split second later while she was talking the entire time, showing that the shot with both hands was a stunt double and not her.

Revealing: In the scene (in the extra/cut scenes) where Rachel an her sister are talking in the dead girls room, her sister opens the closet and we saw a flashback of the dead body sitting in the floor. If you use the pause key, you can see a drawing in the floor indicating where the girl should stay to make the shot. Second later we see the closet without the chalk drawing.

Continuity: When Rachael is approaching the top of the ladder upon entering Samara's room at the stable, the camera is following her from behind and it shows her reach the top and wait there for a few seconds, yet when the camera shows a front on shot, she hasn't reached the top yet.

Revealing: 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.

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 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.

Continuity: 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.
