Now, this is not Holland saying that Chalotra is ugly, or that they cast someone ugly to play the role of the most beautiful woman in the world. … Rather, Holland is saying that she is challenging the “standard of beauty” by casting a woman with slightly darker skin.
I do understand that traditional Western fantasy is predominantly white, but I disagree fundamentally with the notion that the “standard of beauty” for most people is being white. I don’t think anyone in the entire world outside of a tiny, tiny sliver of absolute racist scumbags would look at Anya Chalotra and think anything other than “This woman is jaw-droppingly gorgeous.” Casting Chalotra may challenge our perceptions of fantasy as white (a complicated discussion on its own) but it does nothing to challenge any standard of beauty.
It seems like a lot of people are just not reading the article or the context of the quote:
