Dying for more alternate homoerotic history of the Spartans from Zack Snyder? Well, your wish is his command. Today at Comic-Con, Snyder announced his next project, a sequel to 300. Frank Miller is penning a comic called Xerxes that the movie will be based on, and Snyder is about to start work on it with his writing partner from 300, Kurt Johnstad. This is Sparta - again!
