Continuity mistake: In the last 30 minutes of the movie, Christina Applegate's character appears to be wearing a black rope necklace tied in the front with the ends draping down the front of her chest. When they arrive at the motel, the necklace changes to a black scarf. In the closeup you can see the sheer material has changed, with the ends of the scarf no longer visible. After she is locked in the bathroom, and escapes, the rope is back, tied in the front. When she gets in a car and is pulled over by the cop, the scarf is back.
