Visible crew/equipment: In the scene where Bella walks toward the strangers on motorcycles, her mic wire is visible through her jeans.
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.
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.
