Has absolutely zero effect on the actual quality of the movie.
And saying that, kinda implies (even if incorrectly) she needed to be a white person. Which is not true.
If you’re saying no, I don’t care about the race just the hair, I can promise you a movie of this size tired and debated/discussed multiple hair styles and colors including blonde and decided that the hair the actress has now in the movie looks and worked best.
Plus the excuse that oh she doenst look “native to area ” does not hold weight ether. The live action version of the movie has chosen to still be a live action cartoon in terms of tone. It’s got the whimsical vibe and design of an animated film. It’s not going for realism.
If the film wa truely a live action movie where they tried to make the film as realistic as possible with a Ridley Scott, Nolan, movie tone. Then sure you can say hey, i want this be and feel more authentic maybe
But this movie is not that. It’s like a Disney live action remake. Its whimsically inspired live action cartoon (not in negative way but tonally)
