The battle in Greece during the Persian Wars had King Leonidas leading a small group of 300 men against a gigantic army of over 300,000 soldiers; a suicide mission, really.
The 2007 movie was a massive moment in Gerard Butler’s career and still his most recognizable role in cinema.
The actor was honored to join the Greek people for the 2500th anniversary of 480 BC’s Battle of Thermopylae, which is the specific event 300 is based upon.
