I too am looking forward to this movie. Hollywood puts out about two good movies a year, and I see them both!
BTW, Ultimate smack talk award of all time award goes to Leonides.
Emissary of Xerxes: "We have so many archers, our arrows will blacken the skies...."
Leonides: "Hear that Lads? We get to fight in the shade!"
...or someting really close to that!
BTW, the true signifigance of the battle is that the delay of the Persian army allowed Athens and her allies to get their collective arses in gear and organize an evacuation of Athens, and to get their Navy in position to sink enough of the Persian fleet that Xerxes turned back. What we think of as Western Civilization hinged on Thermopolye, and thus is deemed, by many, the most important battle in Western Civilization.
OK, History lesson over. Now, what if Leonides had a unit of Machinators and a few Attillas....
