A new study puts a spotlight on inequality in popular films, finding that fewer than one-third of the speaking parts in the most popular films released from 2007-2014 were female.

The AP reports that the study from the University of Southern California’s Annenberg School for Communication and Journalism, released today, examined the 700 highest-grossing films during the period.

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

The report adds: “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.”
