Continuity mistake: In the initial view of Billy in the tree ("saved for later" by the leopard sleeping on another branch), his head is hanging face up alongside a tree branch as wide as his head. When the camera zooms in showing the middle of Billy's face, the left side of the screen should be all brown, representing the branch. Instead, there is blue sky down to his eye and blurred tan/brown representing the branch. The brown might supposed to be the dried grass, but Billy has not moved his head. (00:51:25)
Continuity mistake: When two officers go to inform Ronald Whitlock (Bruce Willis) about his sons, Ronald shoots his pistol at the Black officer and hits him near his inner right eyebrow. (A large black spot can be seen between his eyebrows.) When the camera shows the dead officer, the black mark is gone and the bullet hole is on his forehead centered about 2" above his left eye. (00:06:40)
Continuity mistake: A back view of the group of four-wheelers starting out driving through the field showed distinct tire tracks in mostly low, dry brown grass. Various other views showed little or no discernible tire tracks, tall lush green grass, and mixed dry brown and green grass. Even though the four-wheelers appeared to travel some distance, the end of the field that was visible from the onset was just reached. (00:21:35)
