Factual error: When they run out of fuel at the pumps, a truck with placard 1203 rolls up for Emilio to refuel the underground diesel tanks. Diesel is 1202 - 1203 is gasoline.
Factual error: The rocket launcher that is used on the big yellow plough is a single shot M1A1 L.A.W. (Light Anti-tank Weapon). However, the woman then picks it up and fires it again. It could not have had another rocket in it, and reloading it takes much longer than the few seconds between firings in the film. Plus Joey didn't connect the firing clip to the trigger mechanism, as would be needed.David Mercier
Visible crew/equipment: When the trucks have been circling the diner for about 20 minutes, in a leading shot of the big green goblin head on what appears to be the main truck, you can see a light coloured car in said truck's shiny metal bumper, but there are just trucks in the circle of possessed vehicles. The truck in front of the green goblin head truck isn't that colour either.
Revealing mistake: During the scene where Curt and Connie stop at the gas station, When Curt jumps to avoid the tow truck, you can see the dead gas station attendant (or possibly a crew member) laying down. When the truck skids to a stop you can briefly see him get up and move around behind the bushes to the left.nazereth666
