this topic is stupid, and I highly doubt that the black community has anything to do with Troy's production or casting
This, and in addition, not only were the Greeks involved in trade in Africa but as far as I know, the series only depicts Achilles as black. More importantly, it's talking about a fictional period, not a historical reenactment. Not only do we not have evidence that it actually happened, but the 'historical account' actually includes the goddess of discord throwing apples at the other gods, a man who bathed in a hell river, and literal fucking eight-story horse (that's not to mention the sequel, which includes a cyclop, magic arrows, and fucking mermaids). So I'm not really sure how the fuck anyone could mistake this as a documentary in the first place.
Zeus is also black
Again, I don't think you can argue he was 'historically' anything.
