In 480 BC eh? Well, I take it you're referring to the battle of Thermopylae. In which case, despite the heroic and legendary stand of the Spartans, they ultimately lost the battle, and it wasn't until a year later that the invading Persians were repelled. The Athenian navy had as much to do with this as the Spartan army. Now, I understand given today's political climate that Sparta seems a better choice than Persia, but I think it's worth mentioning Sparta relied heavily on slavery. The Achaemenid era of the Persian empire on the other hand, given that their de facto state religion was Zarathustrian, prohibited slavery. You'll note such references of this in the Bible where Cyrus the Great, upon conquoring the Babylonians, frees the enslaved Jews and implores them to return to Jerusalem to build a great temple to honor their god. In Athenian literature like Aristotle's The Politics, an equal bias and disdain exists against both the Spartans and the Persians while other Athenians like Xenophon enlisted and fought for both the Persians and Spartans. And in terms of physical pigmentation or physiognomy, I suspect a great deal of the Spartans would pass for Persians and vice versa. Andre Agassi could pass as a Greek, no? IOW, an action movie is just that and nothing more. I'm not Persian by the way.
