Continuity mistake: When Rachel goes in to Max's bathroom, all the water falls down from the ceiling drenching everything, but then Max comes in, and takes a dry brown towel off the rail to wrap around Aidan. The white towels behind them are bone dry too. (00:46:05)
Continuity mistake: When Rachel sits next to Aidan as he is in the hospital bed unconscious, as the shots change, the amount and position of the wires next to his head (to his right) keeps on changing. (00:50:35)
Continuity mistake: When Rachel pulls up to the old Morgan house she parks her vehicle on the gravel drive, angled into some tall grass. Yet when she leaves the house with the book, the vehicle is now parked halfway on the main road and is no longer angled (but is now much straighter) and is not facing any tall grass. (00:55:35 - 01:01:50)
Continuity mistake: When Rachel is in the basement looking through the book and sees the newspaper article, if you pause the film when the article appears close up, you can read some of the article. This article has nothing to do with the title and photo caption above it, about the young girl in the bathtub, it appears to be about something political. The filmmakers assumed the article would flash by too fast for the viewer to read. (01:03:35)
Revealing mistake: When Hayden is talking to the Psychiatrist in the Hospital, he is wearing some type of white powder face makeup to make him appear more "ghostly". This makeup was only applied to his face. Whenever they show a side shot of his face and neck during this scene, you can see the demarcation (line) of where the white powder face makeup ends and his natural darker tan neck begins. (01:05:20)
Audio problem: In the flashback when Evelyn is walking into the small water fountain with baby Samara, the baby is heard screaming and crying unhappily. Yet when we see the baby's face her mouth is barely open and she doesn't look like she's crying. (01:07:30)
Continuity mistake: When Rachel has the dream of Aidan telling her to kill him, there is a shot where Rachel looks as if she is about to stroke his face, and the next shot her hand is not on Aidan. (01:20:50)
Continuity mistake: As Rachel is preparing the peanut butter and jelly sandwiches, she places the knife on top of the open PB jar in a closeup, but in the very next shot the knife has disappeared, then reappears again. (01:23:15)
Continuity mistake: When Rachel takes her first bite from the peanut butter and jelly sandwich, in the wideshot she is chewing her bite. Then it cuts to the closeup of her, the food is suddenly gone from her mouth. (01:24:05)
Continuity mistake: Rachel prepares some peanut butter and jelly sandwiches, then brings them into the lounge. She then takes a bite out of it. Then, when she takes the second bite, the first bite she took has gone. (01:24:10)
Continuity mistake: When Rachel is placing Aidan into the bathtub slowly in order to try and rid Samara from his body, as she places him in the water, how deeply she has him in the water keeps differing from each shot. (01:26:40)
Continuity mistake: After Rachel pulls Aidan out of the bath near the end (before she face Samara) as she tries to wake him up, in one shot she places her hand on his face and shouts his name. In the next shot her hand is now on his neck. (01:28:40)
Continuity mistake: When Rachel falls down into the well, she has her arms up on the wall and on her right hand there appears to be a leaf or large insect or some kind. The shot changes several times, and the object keeps disappearing and reappearing. (01:31:30)
Visible crew/equipment: When Rachel starts to climb out of the well water onto the well wall, in the closeup of her left side as she lifts herself out of the water, a long white cord/wire hangs straight down her left side from her shirt to her pants. (01:36:05)
Continuity mistake: When Rachel is trying to get into the girl's house, she isn't wearing gloves, but when she is flipping over the rocks she is.
Continuity mistake: When Aidan is in the hospital, Rachel talks to him. When the camera zooms in, you can see the nasal cannula is hanging half out of his nose, but when we see the whole picture it's fully in his nose. When the camera zooms in again, it sticks out again.
Factual error: There are several problems in the hospital scene where the psychiatrist commits suicide by giving herself an air embolism (injecting air into a vein): the volume of air she injected wasn't large enough to cause death (it appears she used about 30Ml, over 100Ml would be needed), death wouldn't be as quick as was portrayed, and it wouldn't be nearly as "peaceful".
Continuity mistake: In the first Ring it is revealed that Samara was in fact the Morgans' daughter. They showed her birth certificate with the Morgans as the parents and then the father before killing himself yells that his wife wasn't supposed to have a child. Yet a huge part of the second movie is about how Samara is adopted and Rachel talks to her real mother in an asylum. Um... What happened to what was found out in the first film?
Answer: It was the only way out. She followed Aiden's voice to the cliff and kept hearing it from the same direction. She knew she had to jump off to get back to the real world.
