I think there's a good reason that this movie had so many deformed characters. All the in the movie the character's outward appearance reflected their inner self, the Spartans were great warriors singlehandly saving Greece(I know this isn't historically accurate) so they were all muscled up and handsome. The Ephors were evil men who had let greed stray them from what they were supposed to be doing and as such they had that disgusting look abou them. Ephialites was a traitor to Greece, who couldn't stand up to the patriotic Greek ideals, as such in the movie he couldn't stand up to the Spartan physical ideals. The councilmen were weak and powerless to do anything in the face of the Persian threat, they were portrayed almost universally as older, less physically fit men and so on and so forth. Every external appearance in this movie reflected in internal condition.
