Other mistake: Virgil drives the truck across flat land, yet the dashboard and A/C unit atop it are angled at about 45°. Views of Keith in the passenger seat show a level/horizontal dashboard and A/C unit, like they should be. (00:17:12)
Continuity mistake: Virgil is speared on the left side of his body by a dead tree limb, but after he crawls to the gold and turns onto his back, the spear is on his right side. He eventually pulls it out of his left side. (01:16:28 - 01:17:38)
Continuity mistake: The perimeter of the small fires surrounding Virgil is bigger compared to the aerial view when the dogs attack him. Also, sticks comprising some of the fires are different, appearing to have never been aflame. (01:26:04 - 01:28:12)
Deliberate mistake: Four hungry wild dogs are biting/eating at Virgil's abdominal area for some time, yet when the body is shown, some intestines are on top of his seemingly still-intact stomach - little, if any, of Virgil can be eaten by the "ravenous" dogs despite the length of time they are there.
