Continuity mistake: Several times, Casey is seen running across a bridge. From the high angle, snow can be seen along the right side of the bridge. However, when the shot switches to a view from behind her, the bridge is clear of snow from edge to edge. (00:01:05)
Continuity mistake: At the beginning of the scene in which Romy hits the little boy with her car, the camera is following behind her car. We see that she is about to pass a parked SUV on the left side. The camera then cuts to inside the car looking at Romy and the driver side window, and we never see the SUV that she was just about to pass. (00:49:15)
Continuity mistake: When Romey hits the little boy, she immediately parks her car and gets out. She closes the door behind her and runs to the little boy. After making sure he is ok, she goes back to her car and the door is open.
