The Bechdel test asks if a work of fiction features at least two women who talk to each other about something other than a man. The requirement that the two women must be named is sometimes added.
Originally conceived for evaluating films, the Bechdel test is now used as an indicator of gender bias in all forms of fiction. Almost half of all contemporary films fail the test, and critics have noted that the test is most informative when applied in the aggregate, because individual works may pass or fail the test for reasons unrelated to sexism.
Here's an official website with movies that pass/fail/partially pass the test: http://bechdeltest.com/
When you think about it, it's a lot harder to think of movies that pass than you would expect. Which should say something about the state of female roles in movies.
