Revealing mistake: The first time we see the artillery blow up a group of Confederate soldiers, the guys wear pretty distinctive hats; the one at the center has a red band on it, the one to his right a straw hat, etc. Ten seconds later, the artillery blows up another group of soldiers...who are the exact same group from before. It's just another take. (00:00:30)
