The movie "300" from the Persians' perspective. It's very interesting that the movie (most probably because it is meant to be told from the perspective of a Spartan storyteller) manages to portray Sparta as a vanguard of civilization and freedom against Persian tyranny and oppression. In reality, the Spartans had possibly the most horrendous system of slavery that our species has ever seen in its history, and the Persian Empire which ruled a quarter of the known world had been built without slavery. While Xerxes did blitzkrieg the fuck out of Athens and most of Greece, his personal history and portrayal as a divine leader/cult figure among his own people would probably be just as interesting as "angry bald sex god warlord is coming for your culture".
