Jessica Rabbit, Catherine O'Hara, etc.
The "sultry redhead" has always been a staple in classic media, which still forms most of our opinions and tastes today.
However, Hollywood is on this SJW bend of "subverting expectations" lately, especially when it comes to culture/beauty standards formed in "classic" Americana (see: "racist, sexist, actual hell on earth where white males dominated and tortured everyone else", from an SJW lens), hence whenever they make a big deal of something like MOST BEAUTIFUL WOMAN IN THE ENTIRE WORLD LUPITA NYONGO JUST UTTERLY PERFECT AND GORGEOUS IN EVERY WAY, they feel that, in some distant way, they're really "sticking it" to the racist old white people of the past.
It's basically, if you want to imagine a convenient strawman, some Hollywood SJW jew exec wringing his hands and saying "Oh, so you think redheads are hot, you evil white racists? Well now she's an average-looking black woman, get used to the NEW standard of beauty, or find yourself on the wrong side of history! Now comply and say: She's so gorgeous and beautiful! And don't you dare mention how she looks and/or acts nothing like the source character, or you're an evil racist too. Look, see? The source material says she's spunky and independent, therefore our new casting/writing is a perfect match, but all you can see is black skin, racist. Please place all awards in the basket to the left, thank you."
