Other mistake: The Blazer was only hit twice by the baseball bat, once on the right front fender, and once on the grille, but it sustained a massive amount of damage. Also, when the infected guy was inside, throwing up blood, you could see that the windshield was cracked in several spots, but it was never hit.

Revealing mistake: When Bert is running in the woods, away from the local guys, he rubs blood on a tree to make them believe he ran a certain way. Look close, the tree already has red tint on it probably from previous takes that didn't wash off. (01:04:35)
