According to FiveThirtyEight
, the domestic Return on Investment of movies that pass the Bechdel Test
is $1.37; for movies in which the women never get to talk to each other it's $1.22; movies that don't even have two named women, it's $1.00.
Since Hollywood believes that international markets don’t want to see women in film, we also broke down the median return on investment for films based on domestic (U.S. and Canada) and international box office numbers. We found that Bechdel-passing films still have comparable returns on investment when the movies “travel."
In other words, treating women characters as if they were human beings makes you money.
