Zack Snyder has finally agreed to make a sequel to 300. He was always hesitant to commit until he saw how Frank Miller's Xerxes comic turned out. If it wasn't awesome and didn't loan itself to unnecessary slow-motion, then it wasn't going to happen. Luckily for ab-crunching actors everywhere, Miller's comic made the grade. Snyder tells the LA Times what we can expect from the sequel:

"This movie follows Themistocles and the Battle of Artemisium, which coincidentally happens on the exact same three days as the Battle of Thermopylae [which was the basis of '300']," Snyder said. "This one starts off with a quick retelling of the why of the Persian wars. It starts off at the Battle of Marathon and then it goes back to Themistocles  finding out that Persians are invading again. and off we go over to learn a little bit about why Xerxes is the way he is."

I'd always assumed he was that way because of a handsy uncle.
