Study shows inequality is still a problem in film

A new study finds that less than a third of speaking parts in the most popular films from 2007 to 2014 were female.

The University of Southern California's Annenberg School for Communication and Journalism released a study Wednesday that put Hollywood's on-screen gender and ethnic equality in sharp relief. The study evaluated the 700 top-grossing films between 2007 and 2014.

USC found little signs of improvement. In 2014's most popular movies, 21 percent featured a female lead, about the same percentage as the 20 percent found in 2007.

Behind the camera isn't better. Of the top 100 films in 2014, only two were directed by female filmmakers. In 2007, it was three.

In the same time span, only three films out of the 700 were directed by African-American filmmakers.
