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.
Revealing mistake: The movie is set in the USA, however, when the US Coast Guard boat ends the search for the husband's body and returns to the dock, Ashley sits on a gray bin with the words "City of Langley" on the side. Those shots were filmed in Langley, British Columbia, Canada.
Revealing mistake: When Nick Parsons /Jonathan Devereaux knocks Libby out, if you look carefully before he puts her in the casket you can see he's holding a dummy/doll from the wide angle. (01:23:53)
Revealing mistake: When Libby goes to the house to kill her husband with the gun she checks the bullets. You can see the firing pin is drilled out, rendering the gun inoperable.
Suggested correction: It's never stated that she was charged with 1st degree murder, nor that she killed her husband for the insurance money. It was only brought up in trial as motive. Nick's accident was ruled "wrongful death" and the fact she did get paroled further show she was never convicted of 1st degree murder.
And what about the phone call from prison the Libby makes to Angie, and Angie says she "was just about to call her" or she tried calling her like how the heck can you call someone in prison!?
