Other mistake: In Volterra when Edward has his shirt off, his face and neck are a different color than the rest of his skin.
Other mistake: Bella just got back from the meadow with Laurent. She is describing what she saw to her Father and Harry. Notice that every time she talks there is a grey/black line across her chest. It is obviously not a necklace or her hair. But then her Father says "Wolves, You saw them?" Now, everytime the camera pans onto her, the grey/black line is gone.
