Since the original was such a success (ahem), now there’s a sequel, with different heroes but the same villains. This one is based on the battle of Salamis, and other portions of the same Greco-Persian war. The Frank Miller graphic novel it’s allegedly based on hasn’t even been completed.
The good news is, since our heroes are now Athenians instead of Spartans, we can drop a lot of the macho bullshit, and venerate things like democracy and free inquiry instead of toughness. The even better news is that Eva Green is reportedly supa-righteous and unforgettable as the brains behind Emperor Xerxes.
