Visible crew/equipment: When the camera is focused on an actors face, most of the time you can see white screens and stage lights in their eyes.
Visible crew/equipment: Toward the end of the film, the 300 are in a shell style formation - Leonidas is in front, right before he removes his helmet, drops his spear and shield. It is obvious that the sun is shining on Leonidas and the 300 from behind, toward the ocean. But if you look into Leonidas' eyes you'll see white reflections - these are from reflector screens.
Answer: When Leonidas and Xerxes are talking earlier in the film, Xerxes tells him that no one will remember who Leonidas was. Leonidas tells Xerxes that they will know that free men fought to remain free (or something like that) and that a god-king can bleed. So by wounding Xerxes before he, Leonidas, died, he made good on his taunt.
