During a conversation with George Lucas at the 2024 Cannes Film Festival, the 'Star Wars' creator addressed some longstanding criticisms of his franchise for a perceived lack of diversity in its cast. 'They would say, ‘It’s all white men.' Most of the people are aliens!' he noted.
Depends.
Are the trolls depicted as fantastical, and the humans as mundane? If so it would be pretty rare to have that type of ethnic diversity. (Not impossible, people be traveling)
If the human society is depicted as very unnatural, then to your point who the fuck cars?
And zooming out, who the fuck cares at all? All TV and movies are optional and we spend way to much effort on that shit
The trolls are depicted as being normal inhabitants of the forest.
