There’s equal representation of male and female filmmakers at this year’s Sundance Film Festival.

But  a new study shows there has been little change in the number of women working as directors and producers showcased at Sundance  over the past decade.

Researchers at the University of Southern California’s Annenberg School for Communication and Journalism examined gender disparity in narrative and documentary films shown at Sundance from 2002 to 2012.

The study found that  women working in key creative positions, including writers, directors and producers, make-up  less than 30 per cent of the filmmakers represented at Sundance but women still fare better behind the camera in independent film than they do in big  studio productions.
