So there's this thing called the Bechdel test for movies (a link to that is under the image below). What it does is rate movies based on qualifications.
A movie passes the Bechdel test if:
1) It has two or more female characters ...
2) ... who talk to each other ...
3) ... about something other than a man.
And it fails the Bechdel test if:
1) There are fewer than two women;
2) There are two or more women, but they don't talk to each other; or
3) There are two or more women, but they only talk to each other about a man.
Turns out, those passing the test had a combined $1.5 billion more in revenue than those that didn't. Hmmm...
