Continuity mistake: During the paper cut scene, when Bella is thrown against the table, there are 5 vases of flowers and 3 sets of candles. After she hits the table she lands against one of the vases and knocks the 2nd one to the floor, but the next shot shows only one vase left upright. (00:14:50)
Visible crew/equipment: In the scene where Bella walks toward the strangers on motorcycles, her mic wire is visible through her jeans. (00:32:10)
Continuity mistake: When Bella is in the parking lot at school in the beginning, Edward walks toward her. Bella's hair is neatly pulled off to the side. When he leans in for the kiss it is suddenly stuck to her forehead, and when Edward tells her Jacob wants her, it's suddenly back to normal. (00:05:10)
Revealing mistake: When Edward takes his shirt off on the steps in Voltaire, his nipples are different colors and sizes. The closer one is grey while the far is more pink as though the makeup had rubbed off.
Revealing mistake: In the scene of the fight in the chamber of the Volturi when Felix throws Edward on the stairs you can easily see the body of Pattinson's stunt double, there's a clear six pack, a tanned body and no body hair.
Visible crew/equipment: In the very last scene, right before the ultimatum, if you look into the tail lights on Edward's car you can see various members of the crew reflected.
Continuity mistake: Right before Jacob comes through Bella's window, it shows her sleeping and "dreaming" of Victoria coming to get her. If you look, the camera really focuses on the dreamcatcher and how it's hanging above her on the bedpost. It is hanging off to the side of the middle hump. Immediately, Jacob comes through her window and focuses in on the dreamcatcher hanging on the bedpost which is now neatly hanging in a completely different way, perfectly laid over the center of the bedpost.
Continuity mistake: When Bella is at the cafeteria table with Mike, and he is asking her to a movie, her hair keeps moving from behind her ear to hanging in front, and back again.
