Frank Miller apparently hasn't completed his sequel to the comic series 300, Xerxes, over the course of nearly three years. This pace means the movie version of the story, titled 300: Rise of an Empire, will almost certainly be out well ahead of the book when it arrives in theaters on March 7.
ICv2 reports that Miller has finished two issues of the five-issue series. That's how far along he was when Dark Horse Comics CEO Mike Richardson talked to ICv2 in early 2011. Miller "has every intention of returning to the remaining Xerxes issues when his Hollywood commitments are complete," the site reports.
