Corrected entry: During the burning of Atlanta scene, Rhett and Scarlett are escaping in a wagon. The horse stops, spooked by the fire, so Rhett throws Scarlett's shawl over the horse's eyes. The mistake is that as soon as Rhett grabs the reins, the horse throws off the shawl, and suddenly no longer is afraid of the fire. (01:22:15)
