something about female characters and black characters

In the 2014 film Top Five, Chris Rock is Andre, an actor attempting to transition from hammy comedies to drama. Andre played a smart-alec live-action bear in a comedy franchise; now, in a maudlin historical film, he attempts to play a Haitian slave revolting against European colonialists. In this casting, we get the message that black characters in media are often minstrel-like entertainers or suffering caricatures.

In the 1975 masterpiece One Flew Over the Cuckoo's Nest, a similar point is made (albeit indirectly) about women in media. In this film, Nurse Ratched, played by Louise Fletcher, is contemptible because she appears to be neither of the things women typically are expected to be: sexual or nurturing.

Notes:
Admittedly not a perfect theory, and not a perfect pairing.
Rock also wrote and directed the film.

One Flew Over the Cuckoo's Nest

Reading Ken Kesey's One Flew Over the Cuckoo's Nest. Early in the novel our freewheelin' protagonist McMurphy approaches the insecurely effeminate and possibly homosexual patient Harding following the latter's humiliation during group therapy. McMurphy aims to open Harding's eyes and expose the cruelty of Nurse Ratchet. Harding protests at first, defending the therapeutic methods of the clinic by asserting that its practitioners' expertise is too much for any layman to critique. In other words, the medical community's knowledge is their power. But McMurphy persists, using analogy and his gruff but down-home brand of empiricism to bring Harding to realize that Ratchet's clinic seeks to instill and maintain order through shame. Harding is won over, but then one-ups McMurphy by claiming that they are both peons, separated only by a few degrees.

I can't tell if, in Kesey's mind, Ratchet represents merely a bad apple within the system or if she is the system. Another observation: Having seen the movie many times, I'm surprised by how important a role gender plays in the original story.
