I havent seen it yet but just hoping it's not too American. I watched Troy again recently and forgot how hard it was to watch Americans pass off as Greeks. Like when Hollywood had John Wayne play Genghis Khan. Bad accents, light hair, light eyes, fair skin... It's hard to get immersed into the world when everyone looks like a foreigner with a moosh of bad "ancient" accents from LotR and not Greece.
The cast selection in 300, on the other hand, did a great job despite that movie being super stylised.
