Leonidas, the King of Sparta, rallies his 300 warriors with a speech on the law of Sparta.   At the pass of Thermopylae in 480 B.C., 300 Spartan soldiers under King Leonidas held off the huge Persian army under Xerxes for a couple of days — just long enough for the rest of the Greek city states to assemble an army to match the Persians. The Spartans died to a man, but their resistance kept the Greek Peninsula from being overwhelmed by the invaders. Frank Miller based his graphic novel on this famous last stand. Now, here’s the movie.
