Zack Snyder Reveals 300 Sequel Details

"There's something that happens in history between Leonidas dying at the Hot Gates and Platea," Snyder said. "That's a year that's left out of the [original] movie. A lot happened."

Although it was dramatized terrifically, Snyder's 300 told the story of the Battle of Thermopylae, which occurred in 480 BC. The film's final moments mention that one year later, at Platea, 10,000 Spartan warriors helped defeat a huge Persian force; in a historical context, an equally important event occurred when the Athenian navy crushed the Persians in the battle of Salamis. According to Snyder, "300 Part II" will focus on the intense 12 months when these battles were taking place.

"Frank is definitely working on an idea," Snyder explained. "If Frank comes up with a great idea and draws something cool, there's no reason why we wouldn't make another movie."
