The challenge calls for industry groups to each commit to hiring one female director in the next 18 months.

A host of Hollywood stars have decided to commit to working with more female directors, as it's been understood that in the past decade, only 4% of the best 100 films were directed by women. 

This bore the  #4percentchallenge – an online campaign aiming to increase the number of women directing major studio films. 

It calls on stars and studios to commit to announcing a project with one female director on a feature film in the next 18 months. Organised by the Time's Up movement, the challenge aims to encourage diversity and promote gender balance in the workplace.

Universal has become the first major studio to accept the challenge.

Announced at 2019 Sundance Film Festival, head honchos at Universal have committed to hiring one female director within the next 18 months.

The company's Universal's commitment was confirmed in a joint statement from president of production Peter Kramer, chairman of Focus Features Peter Kujawski and Dreamworks Animation president Margie Cohn.

As part of the TIMESUPx2 campaign to double the number of women in leadership positions, Tessa Thompson officially inaugurated the challenge during a keynote address at Sundance on 25 January. 

Nina Jacobson, Paul Feig, Amy Schumer, Angela Robinson and Franklin Leonard all joined in during a panel discussion at Sundance, and others who have since lent their support include Armie Hammer, Brie Larson, Constance Wu, Janet Mock, Kerry Washington, Reese Witherspoon, J.J. Abrams and Bad Robot, and Jordan Peele, among others.
