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 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: When Libby is escaping Travis at the art gallery, she backs her truck into his empty rental car that is blocking her, slamming it out of the way. She then rams into it with the front end, hitting it broadside, toppling it. As she takes off, she swerves and smashes a curbside phone box, knocking it over before driving off. After all this, her truck shows virtually no damage to the front or the back, not even a broken headlight or taillight.
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.
Suggested correction: Langley, BC, is a landlocked city in the Greater Vancouver area, so this was filmed somewhere else with Langley's markings on the vehicles.
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.
