I got to be brutally honest: You give me a movie about 17th century British royalty with 50% of them black, I will feel just as offended as if you remake 30 years a slave with whites as cotton pickers.
Not everything inclusive is good. Especially if it distorts the actual history that has happened.
I would rather have my kid ask questions about skin color, etc., after watching 30 years a slave, than have her not be moved about it, cause half the slaves were whites.
That's like replacing the swastika in second world war movies with the Union Jack, because the Union Jack is less offensive (depending on who you ask, though. I bet the Indians have their own opinion about that).
Or why not remake the Stalingrad movie with half of the actors on both sides being black? Historical accuracy apparently has no relevance anyway.
And I am pretty sure a black Gandalf or Legolas would not have sit right with 90% of yous.
Reminds of the movie adaption of Hitchhikers guide to the galaxy were a dominantly as pale and redhaired described character in the book was played by a black man. Would it have worked without the book... maybe. Did it work while knowing the character was a cheesy redhaired char from Beteigeuze (something that was repeatedly made clear in the books)? No.
Are you referring to Zaphod Beeblebrox, the character with two heads? He was played by a dark-haired man in the TV series.
That said, I agree to a point. If it's a historical drama that is supposed to be immersive as a historical drama and Queen Mary of Scots is played by a black Nigerian actor, uh, yeah I don't think that's a good casting decision.
The most ridiculous show I ever saw about Mary, Queen of Scots is the TV series
Reign. The only thing that show got right is that Mary Stuart really existed, the French royal family really existed, and Elizabeth I really existed. The rest of the show is utter crap, and the only reason I watched as long as I did was because Megan Follows played the French Queen. That show is hailed as the WORST EVER for anachronistic costuming, and should also be known as the worst for period dancing (they weren't doing authentic Tudor-era dances, and whatever they were doing wasn't in time to the music).
A day after a work is released you already have 1000 published works of fanfiction and a terabyte of art, safe for work or otherwise, none of which has the author's input or approval.
The difference with fanfic is that it can't legally be published. I've written fanfic for years, and am not legally allowed to make so much as a penny from it, at least not without the approval of the copyright holders. The early Pocket Book Star Trek novels were sometimes revised fanfiction novels - Sonni Cooper's
Black Fire is one of those. I have both the professional novel and the fanfic version. There's another well-known example: Shirley Maiewski's short story "Mind-Sifter." That story exists in multiple versions, from the author's original that was published in a fanzine, the version that's online, the version that was professionally published in the first anthology of Star Trek short stories in the '70s, and finally as a fan film produced by James Cawley's Phase II/New Voyages fan film company. The fan film and professional short story both needed the approval of the legal copyright holders, as all professionally-published tie-in material does, and because CBS cracked down on fan films a few years ago after the guy who collected $$$$$$ from crowdfunding to make a fan film about the Battle of Axanar basically embezzled the money for other purposes and tried to market a line of coffee using the Axanar label/logo ("Axanar" is already legally owned by CBS and the Roddenberry estate).
Yeah, you write essays in high school analysing the work and what the author intended, etc. So what? Your interpretation is probably inaccurate to what the author actually intended anyway. Once the work in out in public, the author does not have the right to tell us the correct way to think about or interpret or remix what they've created. That is freedom.
Some of them do, if they've secured certain levels of approval in the contracts signed when their work is adapted. Why do you think that no non-UK actors appear in the Harry Potter movies?
