The film itself takes place after the events of the first movie, which originally centered around the character King Leonidas, now focuses on a new Greek general named Themistocles, played by Sullivan Stapleton. Themistocles is forced into forming an alliance with the other Greek city-states in order to fight off the rest of the Persian Empire military, much of which was naval warfare that happened at the same time as the Battle of Thermopylae, the battle of the first movie. Speaking of which, Rodrigo Santoro reprises his role as King Xerxes, ruler of the Persian Empire and main antagonist of the story, who will also be shown with a full backstory in many parts of the movie.
Lena Headey and David Wenham also reprise their roles as the Spartan Queen Gorgo and soldier Dilios respectively. 300: Rise of an Empire is going to be released in theaters in 2014.
Liam Neeson ruled the box office last week, but this week he's challenged by an army of ancient Greek soldiers and a talking dog with a time machine. And they're all threatened by the lingering power of LEGOs.
