Continuity mistake: Bella's purse strap falls over her shoulder/arm and stays off for a while, but is back over her shoulder in a flash (i.e., the camera suddenly shifts). (00:06:00)
Continuity mistake: Bella juggles her keys between her hands and walks towards the motel door. Her shoulder strap/purse is on her left side, but is on her right side before she reaches the door. Bella tries fitting the key into the doorknob slot, and her shoulder bag suddenly goes from her right to her left side. (00:09:25)
Continuity mistake: Bella sits on the couch, and the two metal purse strap buckles are atop the front and back sides of her left shoulder. In alternating views, the buckles are a couple of inches lower along the front of the strap. (00:05:07 - 00:05:33)
Continuity mistake: The message pad on the desk is closer to the opposite side of the desk when Bella walks around the desk to answer the phone. (00:24:32)
