Other mistake: When Hannah turns on the magnet, it's so powerful that it pulls the sword out of Donovan's hand from across the room, but no other metal object is affected.

Factual error: The bad guy tells the townsfolk to 'Get out of Dodge.' Not a saying used in 1879, despite Dodge City being a real place. In fact by this time Dodge City was no more violent than many other places, so it wouldn't have been used as a direct comparison either. There's no record of this specific phrase being used until Gunsmoke, in 1955.
