When the tractor trailer arrives at the airport and the rear doors are opened, the inside of the right door shows no markings. After the explosion as Burton and Proctor are going to the car, the inside of the door has a tape strip and a stenciled number on it.(the number also does not match the numbers on the outside of the trailer shown as it arrived.)
In the concluding credits Casey LaBow is identified as portraying "Maggie Bowman" when in fact she is (correctly) identified on IMDB credits as portraying "Maggie Bunker".
