The Bechdel Test is a simple measure to see if a film has:
1) Two named women
2) That have a conversation with each other
3) About something other than a man.
Simple? You'd think so. But less than half the films in 2014 manage to pass the test. in 2015, the test - created by US animator Alison Bechdel - celebrates its 30th birthday. We think it's time to celebrate it with a little film festival in London.
