The Bechdel Test, from the comic Dykes To Watch out For (a comic I'm not familiar with, unfortunately). It is a test that helps illustrate the presence of gender in movies. It isn't a test to determine if a movie is good, or even pro-feminist, just to show how the genders are represented in film. I'm actually a bit sad I hadn't found this earlier (the strip it came from was published in 1985, it's older than me!) It has three basic rules for a movie to pass the test.
1. The movie has to have at least two named female characters.
2. At some point, the female characters have to talk to each other.
3. When they talk, they can't talk about a man.
It is amazing how many movies don't pass this test. My favorite movie, Fight Club, fails miserably (though, it is supposed to be a movie about what it means to be a man in a consumerist society). Although the Kill Bill movies pass, so I can take some solace in that. I have enjoyed applying this test to all the films I have seen recently, and I think it's kind of sad that more movies don't pass. Do filmmakers really think that if two women are on screen not talking about men that I will lose interest? Ah well, maybe they will get the picture eventually.
