Other mistake: During the climactic gunfight Jay Swan retreats to his car. Using his binoculars Swan looks to the left and slightly rear of his car to see Pete Bailey (who is shooting at him with a high-power rifle). Bailey fires a shot at the car and the bullet strikes the front windshield (an impossibility from that angle). (01:48:00)
Other mistake: Cops do not show up at a desert murder scene "in the middle of Bum Ass nowhere, Australia" on a blazing hot day eating a freshly opened and still hard ice cream bar.
