Leonidas himself sent Dilios back to Sparta before the final battle in Thermopylae,
claiming Dilios had a great talent with words and should deliver the“message” of the heroic resistance to everyone in their homeland.
Shortly before the end of the film, Dilios also appears leading the united Greek army at the battle of Plataea, not just
a mere inaccuracy, but also a historical crime, given the leader of the Greek army in this specific battle happened to be one of the greatest generals who has ever lived, Pausanias.
