Have you noticed that movie studios love to objectify an attractive actress by showing off her assets from behind on movie posters? Emily Asher-Perrin of Tor certainly spotted the trend and put together a convincing case about how awfully cliched it is.
Here's how Asher-Perrin describes the mystery adding pose and why movies love to use it for actresses:
Well, it typically does a good job of showing off all of a lady's assets for one. And I'm sure if an actress isn't quite so curvy, showing off her posterior sounds like a good way of ramping up sex appeal. It's also a pose that tells you, in no uncertain terms, "I'm here for you to objectify me. It's OK, you don't have to feel bad about it."
