Corrected entry: In the hospital scene towards the conclusion of the movie, Bella's nasogastric feeding tube isn't taped to her nose properly. As it dangles out of her nose, it is clear that the prop does not have the tubes going through her esophagus and into her stomach, as a real tube would. This misstep has actually led some people to assume it is some sort of breathing apparatus, which it is not. .
Corrected entry: When Edward takes Bella to meet his family, it shows them cooking for her. They all look up, and Rosalie says, "Get a whiff of that" and then Esme says, "Here comes the human!" But Esme's mouth doesn't move: she just keeps smiling. It doesn't sound like Rosalie talking, so it has to be Esme that said it, but her mouth doesn't move from a smile. (01:04:40)
Corrected entry: During the baseball scene, when Carlisle is up to bat, he points his bat forward and in the background you can see Esme, Rosalie, Jasper and quite obviously Kristen Stewart's double with her hat pulled down low to cover her eyes. You can see it is a different person because her chin is quite square and Kristen's is very pointed. (01:17:05)
Corrected entry: In the cafeteria scene when Edward is not at school, Bella looks over to the Cullens' table. If you observe Rosalie extremely carefully, she takes something to her mouth and eats it as if she were human. She is a vampire, and she is not meant to eat anything. It happens again sometimes in other scenes. (00:14:40)
Corrected entry: In the scene at the hospital near the end of the movie, when Bella regains consciousness, she has flashbacks as her mother talks to her. But if you look over her mother's right shoulder (from Bella's perspective), you will see a television; showing the scenes containing the destruction of James and Bella tumbling down a flight of stairs, which are being played in a loop so that they could simply switch to a second camera to capture the flashback scenes.
Corrected entry: In the Dance Studio, there is a point where James rams Edward's head into the mirrors, shattering the surface. However, Edward's reflection on the shattered surface remains intact, instead of being a fractured reflection, as would have been the case when a mirror shatters. (01:34:25)
