Back in April, Hanah Anderson and Matt Daniels compiled data from IMDB and over 2000 screenplays in an effort to accurately visualize the breakdown of male vs female character dialogue in film.
The result is this comprehensive dataset that in fact proves that men have more dialogue in film than women, a fact often reported but never backed up by actual data. Well, here's the data.
The cool thing about this data is that you can input a movie into their search and see how that film stacks up in the male vs female data. Go check it out.
