(at about 47 minutes) When Esme and Carlisle arrive with their final witness, Alistair, Edward tells Carlisle that eighteen vampires have turned up; immediately afterwards Bella says in her voice-over: "We opened our home to eighteen vampires."

(at around 1 hour 13 minutes) Aro has a tendency to attack covens in order to 'collect' vampires who possess unusual talents. Yet when he brings his force to Forks, the only vampires showing extra abilities are the brother and sister from his inner circle. Meanwhile, about half of the Cullens are practically superheroes.
(at approximately 30 minutes) Renesmee is shown growing rapidly against a height chart. When she "pauses" and Carlisle places a book flat on her head to mark her height, the book sits at least an inch above the crown of her head.
