In a recent interview director Zack Snyder spoke about the 300 sequel. Snyder said that Miller is creating the story as a comic right now.
“I know for a fact that Frank [Miller] is writing right now,” Snyder said. “[He’s] drawing away and seems to be knee-deep in it. I think he’s going to head back to Greece again and do another reconnaissance.”
Miller also promised a grander scale for the sequel, even though he wants to maintain the 300 look and feel.
“I think we would use the same technology… I don’t want it to look too Star Wars-ian… Just from what [Miller] told me, it would be bigger as far as landscape and terrain. We’re going to see Athens and the Aegean and other places. There would be an opportunity for bigger visions, though I’d hope for the same aesthetic. The tech we used for ‘300’ was not a revolution. It’s basically what the weatherman has. Look, instead of Accuweather it’s Sparta… It’s going to be the same way, but on crazier steroids.”
