I read about this test the other day. It was made by Alison Bechdel back in the 80's, I think. The test is pretty simple. It tests movies on three criteria:
1) there have to be at least two women in the movie
2) who talk to each other and
3) the women have to talk about something other than a man.
It's amazing to see all the movies that fail to pass this test. You can see a whole list here.
