"Not a lot of narratives are also invested in our humanity," explained Davis. "They're invested in the idea of what it means to be Black, but…it's catering to the white audience. The white audience at the most can sit and get an academic lesson into how we are. Then they leave the movie theater and they talk about what it meant. They're not moved by who we were."

It's not so much her role, but rather the negative impact it had on her body image.
