Factual error: When they first get attacked in the mini van, the side windows crack and get scratches. (You can see the "spider webbing"). A side window shatters in small pieces when they crack slightly.
Visible crew/equipment: In the scene at the gas station where the father is explaining to the son how he met his uncle in high school, right as he begins explaining it you see somebody's head dip behind the head of the father, but you don't see it come out the other side. (00:20:42)
