Continuity mistake: In the beginning when Novalee and Willy Jack are leaving to go to California, Novalee asks Willy Jack to take a picture of her friends. When he takes the picture, she's almost entirely facing him. However, when the picture is on the visor on Novalee's side of the car, her back is completely turned away from him and all you see is her back and the back of her head. (00:01:40 - 00:03:05)
Continuity mistake: When Sally Fields visits Natalie Portman in the hospital she is smoking a cigarette. If you watch at one point she supposedly throws the cigarette down and steps on it but when the camera shoots back at her she has the cigarette in her hand. Then the cigarette goes from not being lit to being lit and Sally again throws it down and steps on it.
Factual error: When Novalee is locked inside Wal-mart during a storm she looks out the front. Water is streaming down the front doors. The problem with this is that the doors of the Wal-mart are very far under an awning and would never see that sort of rain. The awning is shown a minute or so before and is a standard Wal-mart feature. (00:16:45)
