Continuity mistake: In the scene at Mr Bingly's ball, where Lizzie is looking for Charlotte, she obviously notices her and starts walking towards her with her arms stretched out, palms down. In the next shot, her palms are turned upwards to take Charlotte's hands, who have hers palm down.
Revealing mistake: When Darcy has caught up to Elizabeth in the end and they are kissing in the street with the police cars around them, if you look at the side of the cars, you can see that these Las Vegas, Nevada police officers are driving cars from the Provo, Utah police force (where the movie was primarily filmed). (01:36:50)
Continuity mistake: When Elizabeth first meets Mr. Wickham, the sunlight on her hair changes between shots. When we see the back of her head, there is no sunlight on it, yet when we see her face, we can see that there is sunlight on her hair now.
