I totally understand the problem, but....... I think some movies should have the right not to feature diversity for the sake of having it.
Burton's words are awful.
But there are many examples of towns or social groups in the UK with almost no diversity at all.
I understand why they would rather avoid bringing in "token black guy" etc... if nothing asked for it in the story.
It's really lucky that Star Wars managed to include diversity perfectly, you never ask yourself why they're here.
Hopefully this opens the door for many movies that don't hesitate to do that. They get whoever fits the character, good actors, regardless of race.
There's no problem with making a movie that has only white actors in lead roles. That's still far more common than "forced diversity". The question is usually posed to get directors and other people in positions of power to think beyond casting all white people just because that's what they've always done. No one is forcing anyone to change their ways, but reflection might lead to change. Honestly I'm waiting for someone to just say "the majority of the people we cast are white just because that's how I want it", instead of going on rambling half-related tirades about being offended by a Brady Bunch episode. Just be honest and say you never thought about it or you just wanted it that way, damn lol. You'll notice most of the criticism is about Burton's terrible response and no one's really demanding he be more inclusive in future films.
It's so strange that minorities have to have a "reason" for being present in a world, no matter how fantastical or whatever the world itself is. Minorities, women, gay people, trans people etc are all individuals that don't have lives and stories informed only by their being minorities or a woman or gay or transgender. Like honestly isn't it the least bit troubling that white (and usually male+straight) is a default that needs no further explanation, but anyone else better have something in writing?
The setting is also pretty irrelevant in most cases. History, for example, is usually much more diverse that people give it credit for (I had a great blog with examples, if I can find it again I'll post it), and we exist in an increasingly global world. Honestly this is a subject we could do a whole thread about.
Another advantage of having more diverse casts is that you have more leeway to mess up characterization or to cast a minority in a negative/villain role. Some people are side-eyeing the movie now that they see the only black man in it is a villain, but if you have a history of giving minorities varied roles you generally don't have to worry about claims of tokenism. And lastly it's not impossible to consult with people if you think a bit of characterization is offensive, tokenism, or will draw criticism. It's not by accident or luck they managed to include a leading black role in Star Wars and have it be natural and not about how dark his skin is.
Even when the source material isn't super white, it gets white-washed. A bunch of readers including myself thought of Katniss as mixed race because of her comparing herself to her "whiter" sister and mother, but we got an actress where that difference was ignored.
Oh jeez. Mentioning that series brings up memories of the confused, dodo-like outrage when people saw that Rue was black in the movie, when she had always been described that way in the book.
