Corrected entry: When Annie and Hallie are teaching each other about their lives in London and Napa, there are two posters hanging on the wall with floor plans of their houses. One is titled "Annie's House" and the other is titled "The James Residence" but their names are Annie James and Hallie Parker. (00:38:00)
Corrected entry: When the girls are in the isolation cabin Annie's light switch is up but the next time you see it it's down. She never turned it off.
Correction: When Hallie turns her light switch down (off), Annie's is up. Then when Annie turns it on, her switch goes down, which makes Hallie's switch go down. Hallie flips her switch up, which turns the light off. Annie flips her switch down, which turns the light on. Hallie flips up, to turn the light off. Annie flips down, to turn it on.
Corrected entry: Throughout the fencing scene, Annie's hair changes positions as to where it falls. Sometimes there's a single strand of it on her back, and other times all of it is falling down her back.
Correction: Presumably people's hair will change position while they are fencing as they are moving around quite a bit.
Corrected entry: When Jesse is confronting Annie (pretending to be Hallie) about all her new changes such as "being neat as a pin" and how her "appetite has changed" she says how "it's almost as if you were... Never mind it's impossible" implying that the traits she was displaying were traits Annie had, but how would Jesse know these qualities of Annie if Jesse had never met Annie?
Correction: She didn't imply anything, you just inferred it. She could have said it was like she was a completely different person. Or even it was like you were her twin. But that's "impossible" since she doesn't know Annie.
Correction: Chessy HAS met Annie. When Nick asks her why she's looking at Hallie (Annie) that way, she covers by saying that she's looking at her the exact same way that she has been since she was brought home from the hospital. When she says that's impossible, she is referring to the fact that Hallie knows about Annie.
Corrected entry: In the scene in which Hallie is piercing Annie's ears, she puts an apple under her ear to make it easier to get the needle through and to make it less painful for Annie. However, apple juice is highly acidic, and once the lobe was pierced, it would have reacted with the apple, making it extremely painful (moreso even than was demonstrated by their screaming).
Correction: This is a character mistake, and we don't know how painful it felt to them, so their reaction can not be a mistake.
Correction: Her ear was already pierced. You can see it when Hallie is jumping into the lake and looks at Annie. It is clear there, but when Hallie is going to pierce Annie's ear, it appears not to be.
Corrected entry: After the poker game at camp, when Annie is naked and about to jump into the lake, she has left her locket on. There is plenty of moonlight out, so Hallie could easily notice that Annie has the same locket as her, yet there is no indication of her seeing it.
Correction: Though there is "plenty of moonlight" it hardly constitutes a plot hole, just because Hallie does not take notice of a locket round Annie's neck.
Correction: There was moonlight, but she was too far away to see it.
Corrected entry: Before piercing Annie's ears Hallie sterilises the needle by holding it in a flame. However, as the needle's metal and her fingers are unprotected, the heat should travel up the needle and burn her fingers.
Correction: Actually Hallie only holds the needle over the flame for a few seconds. This would heat the needle and her fingers, but not burn them.
Corrected entry: When Nick and Elizabeth are looking through Nick's collection of wine bottles, they come across the wine that they drank at their wedding. She then reads the label and says,"V-G Day, 1945." Well, at the end of World War 2, 1945, it was either V-E Day for victory in Europe or V-J Day for victory in Japan, not V-G Day for what they appear to be saying victory in Germany because the war officially ended in Austria for the European campaign.
Correction: She says V-J Day.
Correction: Nick shows Elizabeth the VJ 1945 bottle of wine BEFORE he shows her the bottle from their wedding; that label reads, "Where Dreams Have No End." The wine from their wedding was the last wine bottle he shows her before they're interrupted.
Corrected entry: The girls' mother says that she didn't even wear a wedding gown at her wedding, but in the photograph, she is definitely wearing one.
Correction: Just because she is wearing a white dress doesn't mean it's a wedding gown.
Corrected entry: In the scene where Hallie has just cut Annie's hair and notices that she has pierced ears, you can see that it's Hallie who says "What?," not Annie.
Correction: No, Annie is the one who says "What?" but her mouth hardly moves. Hallie seems to be grimacing at the moment Annie says "What?"
Corrected entry: In the morning when Annie and her friends wake up in their cabin at camp, after Hallie's gang has trashed the place. Watch the girls as they wake up screaming. One is obviously a blonde-haired boy. This is a girls' camp. The boy who accidentally got stuck at the camp (shown at the beginning of the movie) has dark brown hair, not blonde.
Correction: That's a girl. On the commentary the director says that's her daughter wearing a short blonde wig.
Corrected entry: During the scene right after Elizabeth has just seen Nick and Meredith in the elevator, and is starting to confront the twins, Chessy comes out of her room and tells them to go inside. She doesn't close the door of her own room. So does it just hang open?
Correction: Hotel doors usually are made like fire doors; they don't need to be pulled or pushed shut because they are made heavy enough to swing shut by themselves.
Corrected entry: Annie and Hallie are saying goodbye, Annie's car shows up and Annie (as Hallie) gives Hallie (as Annie) her ticket and passport. Hallie (as Annie) then asks what time the real Annie leaves and she replies, "Oh not for a couple of hours." Wouldn't Hallie know this, as they were her own return arrangements before she switched places with Annie?
Correction: Hallie and Annie spent a lot of time teaching each other how to be the other one; Hallie was making sure Annie knew. Also, they had to make it sound like they were saying their goodbyes to each other and normally your cabinmates don't know all the details about when you're leaving because it doesn't matter until the last day.
Corrected entry: In almost all the scenes in London, the cars are driving on the right side of the road. Aren't the cars supposed to be at the left side?
Correction: The only scene I could see that looked like the car was on the right side of the road was when Hallie first arrives at her mother's house. However, the house is obviously on a one-way street, which would give the illusion of driving on the right side of the road.
Corrected entry: When Hallie(the tom boy) is cutting Annie's hair, Annie has her hair tucked behind her ear. Hallie then sizes up the shortest piece of her hair then cuts Annie's hair accordingly, but Annie's hair is still behind her ear, so the shortest hair would be in the wrong place.
Correction: She's measuring where the hair lies by her cheek, not the amount of hair, she probably already knows that considering its her hair.
Corrected entry: Marva Jr. does not seem to know Annie nor her name at the beginning of the fencing competition. However, she says Annie's name when Annie beats Hallie.
Correction: Don't you think Marva Jr would learn Annie's name when her friends are calling out "Go Annie" at the beginning? How do you know she doesn't know Annie's name? What do you think she is writing while she's saying "We've got ourselves a challenger" right before they start fencing?
Corrected entry: When Dennis Quaid returns from the camping trip he displays an engagement ring that he says Meredith threw at him. She is not wearing an engagement ring.
Correction: She is wearing an engagement ring. You see it when one of the twins hands her her evian bottle.
Corrected entry: When Hallie begins to cut Annie's hair, starting with the bangs, she cuts them about at the eyebrow line. After she's done cutting all of her hair, Annie's bangs are at the middle of her cheek.
Correction: Hallie is holding annie's hair out at an angle so it only appears that way.
Corrected entry: Well, when Hallie and Annie take their parents on the Queen Elizabeth II and are recreating the night they met, there is an inner tube above the dinner table reading, "Queen Elizabeth II" and underneath it the year 1986, supposedly the year they met. However when the parents are in Nick's wine cellar and he is showing Elizabeth his collection of his parents wine, he has one from 1983. She asks him what is so special about that wine and he says it's the year we got married! How the heck do you marry someone in 1983 when you haven't met them until 1986?
Correction: What he says was "It's the wine we drank at our wedding". It's perfectly normal to drink wine from years past.
Corrected entry: When the balloon falls on Annie's head, you can see the tack on her head that is used to pop the balloon. It is not just a hair that is sticking up because it is right over the spot where the balloon hits her head.
Correction: When Annie is about to be hit by the giant water balloon her hair is slightly sticking up in the front. A millisecond before she gets hit she crosses her arms and tucks her head down into them so that the balloon hits her head more towards the back of her head. She has a messy braid and you can definitely not "clearly see the tack."
Correction: Those posters are both for Annie's house, just labeled differently. The edge of a similar-sized yellow poster is visible during that shot, so Hallie probably had a poster or two, but they weren't really shown during that scene.
