Factual error: Disc 2: There is a scene where a cannon shell explodes inside a hospital ward. Everyone in the ward is killed, but there are no signs of limbs torn off or even shrapnel wounds, only some blood here and there. The same thing happens at the Battle of Bull Run when the old woman gets blown out of her bedroom by cannon fire. (01:32:00)
Other mistake: A few times during the whole show there are certain shots where the corners of the screen are blacked out, as if a circular lens cap has been fitted to the camera. There seems to be no logical reason for this, therefore it has to be a mistake. One example is when Jonas is leaving his wife for the last time and he says 'there's a big battle brewing'. (00:07:25)
Abraham Lincoln: It's well known that the more a man speaks, the less he's understood.
Question: When Jonas's wife descends the stairs in her nightgown, you can hear her shoe soles hitting the stairs. I was surprised to see her wearing grey stiletto high heel pumps! As she exits the stairs and enters the kitchen, these heels are fully visible on both feet from the rear. Was she that much shorter than her co-star?
