Frank Miller has spilled the beans on the 300 prequel, revealing the title and some important plot information.

The comic book legend has been working on a follow-up to the original graphic novel, which is now titled Xerxes He toldit will be set 10 years before the events of 300 and focus on another epic conflict: "It's the battle of Marathon through my lens. I've finished the plot and I'm getting started on the artwork."So the battle of Marathon: a history lesson. It was an almighty ruckus fought between Spartan's Greek neighbours the Athenians and the Persian forces of Darius I -- who was (300 villain) King Xerxes' dad.As with the battle of Thermopylae 10 years later, the Greek army was hugely outnumbered but eventually won the day. How Xerses will be involved we're not sure, but the plot may revolve around his struggle to gain the throne or desire for revenge after seeing his daddy defeated.Naturally, 300 director Zack Snyder has already expressed interest in transferring the comic to film, whilst Gerard Butler has also said he wouldif Miller could find a way of incorporating his character.
