The Bechdel Test (women in films)

I meant to write about this a long time ago, when I first came across it. However, I didn't, and now Mark Kermode has reminded me -
here - I'll do so now. Mark is talking about the Bechdel Test (2m 23s). In other words - how to tell if a film includes a proper female role.

I like reading Kermode's blog; his attitude towards women in movies is one of the reasons why.
