On the topic of females in the media, although less to do with body image, there is the Bechdel Test (which you can learn the origins of here). The test was originally intended for movies, but can be applied to any medium. Essentially, for a movie to pass the Bechdel Test, it has to have at least two named female characters who talk to each other about something other than a man.
Think about main stream movies for a moment and you’ll realize that this is a pretty hard test to pass, but I think it’s important to be aware of the fact that this is such a rare scenario for movies. In Beauty and the Beast I talk about being aware of the messages that the movies that you watch are sending and this is just part of noticing things about the media. Re-watch some of your favourite films and see if they pass the test, and what you think about the test itself. Girls talk to other girls about all sorts of things besides guys, but apparently not in the movies… Makes you think, doesn’t it?
