Audio problem: When Dave (Dylan O'Brien) and Aubrey (Britt Robertson) Are walking to her house after they first met at the party they are filming from a wide shot and you can hear both characters talking but their mouths are not moving.
Audio problem: When Jacob and Bella are in the car, on the way to Charlie's, Jacob is laughing about "Dracula 1 and Dracula 2" being "creepy." He lets out a huge loud, chuckle in the audio, yet the audio doesn't match his mouth, as his mouth is merely in a tight grin.
