Continuity: In the scene where a zombie's head is held up in the truck to be shot there is a big splatter of blood down on the face of the soldier. He wipes a very small amount of blood off but when he gets into the other truck he is perfectly clean.

Continuity: When the old car blows up both of the dead zombies are gone.

Visible crew/equipment: When Roger hits the zombie with the truck, notice at the bottom right a trampoline in which the zombie jumps off.

Other: In the aerial shots of the semis being driven in the mall parking lot, the zombies are milling about. Notice they have left a path just clear enough for the truck.

Continuity: When the Sweater vest zombie first goes up to the 2nd floor he appeared coming up to the 2nd floor moments later.

Visible crew/equipment: When the two kids in the airport attack Peter and try to bite him, notice in the top right corner a crewmember's hand comes into shot.

Factual error: In the scene where they are refuelling the helicopter (as a zombie approaches quietly from behind) the actor has put the gas nozzle not into the hole for the gas tank, but into one of the foot-holes that helicopter mechanics use to climb up to the top of the helicopter to do repairs. It doesn't even fit properly.
