I think it's time for a prequel...about how the Persians got their clocks cleaned at Marathon by another smaller Greek army.
Then, we need to put out another movie about Alexander the Great and how he conquered Persia with a relatively small force.
Come to think of it, the Persians must have been real wussies on the battlefield. Did they ever have any notable wins against the west?
Wasnt there an Alexander the Great movie out a couple of years ago?
