Why this is worth mentioning, though, is because I barely recognized Zoe Saldana as Uhura. Bizarrely, she's been so excessively Photoshopped that her black hair looks golden-blonde. And her skin? Well, I'll put an image from the Star Trek site of Eric Bana's Nero glass beside the Uhura glass - can you tell that one actor is white and other's black? (And if you knew nothing more than this distinction, would you misapply those labels?)
edit: And there's probably a common sensical (and so incredibly problematic) reason that their skin colors seem to have been swapped - Nero is 'evil' (his glass is darker and the ship must absorb ambient light, it's such a deep green-black) and Uhura is 'good' (and much like her skin and hair, the ship and its background glow unnaturally). Because good is bright and evil is dark, of course.
