Continuity mistake: When Bob climbs out of the car, running away from Vanessa he runs in a straight path from the drivers seat, very far away from the van and is then shot by Vanessa. Moments later when Vanessa robs him, he is closer to the van and near the rear of it. He is in a different location and his body has also rotated.
Continuity mistake: When Vanessa is sitting at a desk, opposite the two detectives (before she starts talking about what happened - it's chapter 8 on the DVD), her hands keep on changing position between shots. In one shot they're resting on the desk, then they jump to resting on her knee, then on the desk again, and so on throughout the scene.
Continuity mistake: When Vanessa leaves Bob for dead, she has no blood on her face. She goes to a cafe and suddenly there is blood all over her hands and face; the amount on her face suggests it would have been visible to viewers when she left Bob. The light wasn't dark enough to hide so many stains.
Continuity mistake: When Rhonda and Vanessa chat, while they sit on the jail beds, Rhonda's arms/hands keep changing position between back and front shots. They could be resting in her lap, then up fiddling with her hair, then she could have her head resting on her hands etc. It randomly changes throughout the scene.
