In 2016, stand-up comedian Marcia Belsky noticed that in many movie posters, women are depicted without heads or faces, or as disembodied pairs of legs or breasts, turning them into objects rather than people with personalities and agency. She created the Tumblr,
Headless Women of Hollywood to collect such images when she found them in order to make a point about how many of them are out there and presents dozens of examples across all genres of cinema, even children's movies, as well as TV shows and book covers. She also invites readers to submit pictures of similar pictures they have seen.

Jen may have a head, but the woman in the background is just a prop.

Recently the Headless Woman Project has gone viral again, since it is more relevant than ever in the era of #MeToo. Have you heard of the Headless Woman Project, or noticed headless women in posters and advertising?
