Factual error: Ashley Judd is convicted of murdering her husband for the insurance money and that would make it a first degree murder charge (first degree meaning she planned the murder). Because of that there is no way she would have been eligible for parole after just 6 or 7 years.
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.
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.
