Factual error: When Judd is being visited in jail by her best friend and son, you can see she is wearing her wedding band when she holds the phone receiver. Wedding bands/jewelry are not allowed to be worn by prisoners.
Factual error: When Libby makes a phone call from jail, she states to the business that she is Angela Green and she wants to make sure that her severance check is mailed to the correct address. In real life, the business Libby called would've have never accepted the call under the assumed name of Angela Green because when you call ANYWHERE from jail there is an operator on the phone to tell the receiver of the call where you are calling from and who you are, and will they accept the call.
Continuity mistake: In the opening scene where Libby is talking to Maddy. When the camera is in front of them, they're facing each other. But when the camera shows them from behind, they are sitting beside each other.
Other mistake: On two occasions in the movie, Ashley Judd slams a car into another (she drives Tommy Lee Jones' car into another and over the side of the ferry boat, and later she smashes a stolen pickup truck into the side of a car). In each case, the car she is driving emerges from the crash without a scratch on it, not even a damaged headlight.
Revealing mistake: When Ashley Judd slams Tommy Lee Jones' car and tips it over, she drives off and skids dramatically to a stop. Just before she skids, you can see several skid marks on the ground from practice or previous takes.
Continuity mistake: When Libby goes to the BMW dealer, the dealer says the address is 20 Oriole Terrace. When Libby is driving down Oriole Terrace, she passes a house with four digits in the address.
Continuity mistake: In the scene where Ashley Judd leaves prison and first meets Tommy Lee Jones, she brings a box into his office full of her belongings. After he has checked through it he looks at the picture of Judd's son. When he throws it back into the box, it makes a noise as if it has hit the bottom of an empty box. In the next shot Judd picks up the box which now seems to be full with all of her belongings again, even though he hadn't put anything else back into the box.
Factual error: When Libby tries to call the friend's house back after the 'resurrected' husband yanks the phone out of the wall, the tone she gets is fast beeping. That sound is the tone used when your phone hasn't been hung up properly. She should hear a ringing tone on her end since the phone she's calling is still in service.
Continuity mistake: When Libby asks Angie to adopt Maddy, in one minute her legs are up on the chair, and in the next, they're hanging down again.
