Really?!?

I'm not very surprised to hear that more men than women have major parts in movies, but I am surprised that it is as dramatic as it is.  

...In the 120 films the MDSC analyzed, only 30.9 percent of speaking and named characters were women......The United States is far from a leader: Of the 11 most profitable film-producing territories, the United States ranks near the bottom in allocating speaking roles to women.The MDSC, which studies the portrayal of women and minority groups in film, also found that women were more than twice as likely as men “to be shown in sexually revealing attire.”

Unlike the plight of minorities in film--which does make some sense from a pure marketing standpoint--that women would be so dramatically underrepresented is very odd. 50% of the population is female, and so 50% of your potential ticket buyers are female, and so it seems that more female characters and leads would mean more potential revenue.

That women are more sexualized in film: also not surprising.
