Game of Thrones actress Lena Headey is featured on a new poster from 300: Rise of an Empire, which will be available at this year’s Comic-Con.

Lena Headey plays Queen Gorgo in 300: Rise of an Empire, which is a sequel/spin off to Man of Steel director Zack Snyder’s 2007 film 300. As the film is based upon a previous graphic novel, it will certainly have a presence at Comic-Con this year, and we imagine our Game of Thrones fans will be dying to get their hands on this great Lena Headey poster.

300: Rise of an Empire focuses on Persian king-turned-god Xerxes, who leads an army against Greek forces. Though having quite little training, the Greek army are reportedly led by a great general named Themistocles. The film was written by Zack Snyder and Kurt Johnstad, and was directed by Noam Murro.

Check out the trailer for the 300: Rise of an Empire, which landed online back in early June.

Previously, the Xerxes depicter Rodrigo Santoro revealed that the upcoming film would be somewhat of a “spin-off” because “it’s not exactly a prequel, it’s not a sequel.”

He went on to say that, “It takes place in the same time, you start a little earlier but then you see that it’s like a different point of view, a different camera, a different angle. While that battle was happening, the one that you saw in 300, there was another battle happening next to it and you will have a chance to see all of that happening and how they interact. I don’t want to ruin it.”

300: Rise of an Empire’s release date is March 7, 2014. Noam Murro is directing, who is known for his 2008 film Smart People with Dennis Quaid and Sarah Jessica Parker. Rodrigo Santoro is reprising his role from the original 300 as the Persian king Xerxes, as well as Lena Headey, and Sullivan Stapleton (December Boys) plays Athenian general Themistocles.
