Towards the middle of the movie there is a scene where Neville (Charlton Heston) is shooting at "the family" in the streets. He fires a machine gun at some of the family members hiding behind a car. The scene clearly shows bullet holes in the car and a tire bing blown out. The camera is back on him for a moment and then back to the family, now running from behind the car. Only this time, the car is back to it's original condition, no flat, no bullet-holes. AMAZING!
