The Bechdel Test for films is simple. To pass, a film has to have:
1) At least two women in it
2) who talk to each other
3) about something besides a man
Sounds easy enough, but I guess it’s a little too much to ask of Hollywood, because even a cursory glance at The Bechdel Test website demonstrates that roughly half of the films in their database don’t pass. The test’s origins lie in Alison Bechdel’s comic Dykes to Watch Out For, specifically a strip she drew in 1985 called The Rule. (You can read more about it on TV Tropes, and you can also watch a short video about the test here.)
