The multiple Oscar winner has come on board to narrate the documentary about fistula, a debilitating condition that turns healthy African women into outcasts.

Adam Friedman and Iain Kennedy co-direct the documentary, which is being made in collaboration with The Freedom From Fistula Foundation run by the film’s executive producer Ann Gloag.

Friedman will produce through his company Vertical Ascent.

Shout Gladi Gladi also features appearances by Melinda Gates and Nobel Peace laureate Wole Soyinka.

“This powerful film attests to the igniting power of one woman, Ann Gloag, to set in motion hundreds of helping hands, doctors, nurses, caregivers, family and friends, to resuscitate the health and status of victims of fistula, and to give them back their lives,” said Streep.
