In the film 300, he served as an emissary sent all the way from Persia with a party of other Persian emissaries to Greece, demanding for the submission of Sparta to Persian God-King Xerxes himself. But Leonidas strongly disobeyed Xerxes by casting the Emissary and the other messengers into a ginormous pit of terror as he falls to his fate.
