Continuity mistake: When Nicholas Cage comes out of the church, you see his reflection in the car's rearview mirror. His injured eye is his (left in the mirror image) right eye. Later, he is shown with an injured left eye.
Factual error: When Amber Heard dives out of the caravan onto Nicolas Cage's car, the bad guy fires his 6 shot revolver at her at least 9 times.
Continuity mistake: Early in the movie, when Amber's Charger experiences engine trouble and begins to belch smoke from under the hood, there is a quick shot of her speedometer needle dropping to zero. In the next shot, the car is rolling along the side of the highway at 5-10mph, before coming to a stop. The speedo went to zero a bit early.
