Continuity mistake: In the hospital, after the 'almost' car crash when Edward saves Bella, she has a blood pressure cuff on her arm. You can see the nurse take it off. She has it off for a while, but then it reappears on her arm in one shot, just as her dad says "you can kiss your licence goodbye".
Continuity mistake: During the hospital scene, when Edward is "sleeping," his head goes from from leaning on one shoulder to suddenly on the other shoulder in the very next shot. In the top shot there are 2 windows next to Edward's head, but the windows are not there in the next shot. Things on the table have moved too.
Continuity mistake: When Bella enters Biology class and talks to Eric about the prom, she starts to walk, then pauses to look across the room towards Edward. In this shot, the Armadillo is not on the shelf, only what looks like a peice of paper is hanging there. The Armadillo appears on the shelf only after she has sat down at her desk and Edward moves the microscope towards Bella saying, "Ladies first".
Continuity mistake: After Edward saves Bella from being crushed by the van, while he is holding her, Bella's hair is outside of her jacket covering up her hood. When the shot changes her hair is tucked beneath the jacket and the hood is visible. When the shot changes back, her hair is covering up her hood.
Continuity mistake: When the Cullens are in the garage preparing to take Bella to safety, Edward closes the trunk lid twice. First time is not so obvious because the camera is on Emmett and Rosalie, but the trunk closes on the right of the screen. Then it shows it closing again with it being the main shot.
Continuity mistake: In the first biology class, when Edward moves the glass petri dish over to Bella and "hides" one in his hand, a piece of paper is lying crooked between them on Bella's side of the table. In the next shot, both glass dishes are between them, and the paper is on Edward's side, and it's now vertical.
Continuity mistake: When Bella enters the biology classroom and Edward has finally returned, as she walks over to her desk the large book sitting on the edge repositions itself from sitting horizontally to vertically between shots. The bit of paper above it also moves closer to the edge.
Visible crew/equipment: When Edward first brings Bella to his house, as he is leading her upstairs he stops on the bottom step and turns to her to talk. In this shot you can see the faint reflection of the long microphone pole moving up and down in the glass siding of the staircase.
Continuity mistake: When the Cullens are in the kitchen making Italiano for Bella, Rosalie is holding a crystal bowl that Emmett has filled with salad. But when Edward tells them Bella has already eaten, just before Rosalie shatters the bowl, the bowl is half empty, and only a few lettuce pieces fall to the floor amongst the crystal shards.
Continuity mistake: When Charlie is sitting at the table cleaning his rifle and Bella is talking to him, he places the cleaning rod (with the green handle) down on the table. In each different shot the rod is in a different place, either hidden behind the collection red ammo or not.
Audio problem: After Edward runs Bella up the mountain, he is trying to explain to her that he is dangerous. They are facing each other and Edwards says, "I've Killed Before." Bella says, "It doesn't matter." The camera then spans around them and Edward is moving his mouth, but there is no audio.
Continuity mistake: While Bella is hanging out inside the van at the La Push beach and Jacob and his friends come to hang out, Jacob turns to grab a tub of Red Vines. In some shots he has the tub next to him, but in others he doesn't. Also you can see that the guy next to Sam takes a bite of a Red Vine in one shot, and in the next he does not have the Red Vine in his hand anymore.
Continuity mistake: In the scene when Bella opens the book of Quileute legends, the wide shot shows there are no pictures on the pages she turns to. In the close-up shot, when she says, "cold one," there are pictures on both pages. This couldn't be possible, considering that she doesn't turn pages from the wide shot to the close up.
Continuity mistake: When Tyler throws a piece of licorice at Bella to get her to come over to them, Jessica is standing to the very far left (from Bella's view) facing Bella and trying to talk to Mike. After Bella shakes her book at him in response, Jessica is suddenly standing to the very far right (from Bella's view) facing away from Bella and goofing around with Angela.
Continuity mistake: It's nearing the end of the movie. Edward and Bella are dancing under the gazebo. Edward lifts Bella so she is dancing on his feet. The camera later pans onto both of their full bodies dancing. Bella's feet are not on Edward's and she is dancing just fine. It later pans onto both of their full bodies dancing. Bella is on Edward's feet again, dancing.
Continuity mistake: When Bella and Edward are at the salad bar talking about Bella's theories, you can see the table with Bella's friends in the background. If you watch her friends, all of their positions and various actions noticeably change, between the following consecutive shots.
Continuity mistake: In the scene when Bella is in Port Angeles trying to get away form the guys who are taunting her, in one shot, as she is walking through the parking lot, they show two guys walking up from behind her and the other two guys walking toward her. In the shot where the camera shows the two walking toward her, you can see two people dressed in black standing on the deck in the background, and it looks like they go in for a big kiss. The next time the deck in shown in the shot the two people are not there.
Continuity mistake: While Edward and Bella are talking on the school campus on the white bench, the school bell rings. The black boy and the white girl who are sitting behind Edward and Bella hear it and they walk away. But in the next close-up scene, they are still sitting and talking, and in the next shot, when Edward and Bella get up, they are gone again.
Continuity mistake: In the scene in the woods where Bella tells Edward she knows what he is: she drops her backpack by a tree, and in one shot you can see it, but the next you can't only because it's turned upside down so you can't see the red. But it's still there. And in other scene you can see it again, right side up.
Continuity mistake: In the first scene in the cafeteria, when Bella suggests that Angie should run an editorial on "speedo padding on the swim team", she then holds up her food to take a bite with her right hand. However, in the reverse-angle shot, when Angie says "actually, that's a good one", Bella's right hand is seen placed on top of her left arm. Then when it cuts back to Bella, she is again holding the food up to her mouth.
Continuity mistake: When Bella and Edward are coming back from Port Angeles and see that their dads are still at the Police station, Edward starts to pull in and there's what might be an ambulance in the entrance. The next shot shows a semi-close-up of Bella asking Edward to pull in, which he does again, and this time there is no car in the entrance.
Continuity mistake: As Edward and Bella are dancing on the gazebo at prom, the other two couples leave the gazebo. The first couple who leave walk over to the stairs and start walking down them. In the next shot they're still walking to the stairs and then begin to descend them again.
Continuity mistake: When Bella says, "Why did you hate me so much when we met?" Edward's face is very close to hers and his right hand is placed with the palm on a branch. In the next shot, his face is further away, and now it's only his fingertips which are touching the branch.
Continuity mistake: Just before the Cullens begin to play baseball you see Edward running away and beginning to turn around to look back at Rosalie while he is running. But in the next shot you see him walk with his back turned to "us" and then turning around to look at Rosalie.
Continuity mistake: In the ballet studio fight scene, Bella grasps an injured right leg with her left hand. When Bella is in the hospital, the cast is obviously on the left leg which is under the blanket-the silhouette of the leg is straight and much larger than the right leg, which is thinner, flexed and has skin exposed at an area which would have been covered had it been in a bandage or cast. But when she and Edward go to prom, the injured leg is again the right leg, which is in a cast.
Continuity mistake: In the scene right before Edward saves Bella from being crushed by the van, we see her truck parked straight in the parking space and closer to the curb. After Edward pushes her away and the van hits the rear of her truck, it is shown parked farther from the curb, and the back end which was just hit is moved out farther from the curb instead of closer.
Continuity mistake: In the scene where they are driving up to the police station there is only one bright orange paper taped to the door, however close up there are three (orange, blue, black). Also a potted plant mysteriously appears - when they are driving up in Edward's car you can see there is no plant on the porch and when Carlisle comes out there is.
Continuity mistake: At the beginning, when Bella and Charlie first start talking in the patrol car, they stop at an intersection. Through Charlie's window we see a young man walking toward the four way about to cross the street and there is no traffic approaching. In the next shot, there is a rig carrying logs crossing the intersection in front of the patrol car, and the young man is nowhere to be seen.
Continuity mistake: In the scene where Bella and Jessica are outside enjoying the strangely sunny day, there's a boy in a brown shirt sitting in a table behind them. As they are talking, that boy remains seated, but when the shot changes from a close-up of Bella to a two-shot, the boy is suddenly standing up.
Revealing mistake: When Bella and Edward are identifying the different stages of mitosis (prophase, metaphase, anaphase) in the lab it's not possible given the position of the microscope lens in relation to the microscope stage. The lens is positioned too far from the stage for an image of the nucleus to be correctly focused in the ocular.
Continuity mistake: Just after showing Bella his room, Edward takes her up into the tall tree to see the view. In the close-up shot, the tree they are in has a different shape to its trunk and limbs and is actually a different tree type from the one that is shown when the scene cuts to a aerial long-shot and pans away.
Continuity mistake: When James, Victoria and Laurent arrive at the baseball game, in the first shot of their arrival Laurent has his dreadlocks hanging over both of his shoulder. In the very next shot dreadlocks are only hanging over his right shoulder, and then back to both shoulders in the next.
Continuity mistake: In the prom scene just after Edward and Bella arrive, Bella motions to Jess, who is on a raised area with Mike, away from the dance floor. Bella then turns to wave at Eric and Angela. The shot focuses on them and then cuts back to Bella and Edward. In this shot, Jess can now suddenly be seen dancing behind them.
