Ridley Scott's debut movie, "The Duelists" is such a movie. It's based on real diaries of two dudes who dueled several times over course of decades. The sword fighting in the movie is among the most realistic. Check out the opening scene:
Also, the sword fight from "The Deluge" (Polish title - "Potop"). Admittedly, the plot says the commander didn't want to kill a rebelling but skilled officer, just teach him a lesson. But otherwise well done. It was a time when fencing and horse riding training was mandatory for Polish actors.
