After they escape captivity, Lyn and Bob chase down Mahmud in the pickup truck. In shots from inside the truck, Mahmud is running in the middle of the road, only veering off at the last moment. All other shots show him running on the side of the road.
During the gun fight at the gas station, the black security van is shot in the windshield. The bullet holes disappear in subsequent shots.
