Interesting, if long, post at 538 about financial implications of the 'Bechdel Rule'.

Using Bechdel test data, we analyzed 1,615 films released from 1990 to 2013 to examine the relationship between the prominence of women in a film and that film’s budget and gross profits. We found that the median budget of movies that passed the test — those that featured a conversation between two women about something other than a man — was substantially lower than the median budget of all films in the sample. What’s more, we found that the data doesn’t appear to support the persistent Hollywood belief that films featuring women do worse at the box office.
