I first noticed this with the 2014 "Annie" remake -- all the major characters were now black, with the exception of the movie's main antagonist, the eeeeeeeeeevil rich white capitalist owner of the orphanage, Miss Hannigan (which strangely had Cameron Diaz cast in the role). The character is NOT from the comics, BTW. She again originates from the 1977 Broadway show.
They did this again with the recent 2020 remake of Roald Dahl's "The Witches". The little boy that saves the day and his friends are now all black (or gender-swapped to female), but the eeeeeeeeeeeevil antagonist of the story, the Head Witch, remains white. I'm sure the people making the movie will say that is all just a coincidence.
In any case, it seems to be a pattern now.
Disney films and the BBC have a less offensive but still weird trend of the last 20+ years of having interracial couples in a historical setting where such a relationship certainly would NOT have publicly shown or celebrated. The 1995 Annie remake actually did that (Daddy Warbucks was openly in love with and dating a black woman in 1930s NY)
Not nearly as amusing as the ‘99 remake having a homosexual playing Warbucks (Victor Garber) opposite Audra McDonald. McDonald is arguably a great stage actress (her performance as a badly-in-decline Billie Holiday in “Lady Day at Emerson’s Bar and Grill” was magnificent), but I didn’t think she worked in “Annie.”
Going back to the source material, of course, Warbucks was actually married to a harridan who hated Annie and was always trying to get rid of her every time her husband went out of town on a business trip. That would’ve been a problem in the stage or film versions, since you couldn’t have had Warbucks having a romantic relationship with his secretary while married (at least not in a child’s play).
In order to justify genocide TPTB have to gin up the hate and normalize the marginalization of whites.
