Angelina Jolie is executive producing Ethiopian film Difret.
The actress described the film, the big-screen debut from director Zeresenay Berhane Mehari, as "a strong moment for art in Ethiopia", The Hollywood Reporter said.
Difret, which was shot in Ethiopia, will have its world premiere in the World Cinema Dramatic Competition category at the Sundance Film Festival on January 18.
The film is the story of a young Ethiopian girl who challenges the tradition of "telefax", the practice of abduction in marriage, usually of young girls.
The Oscar-winning actress, who adopted daughter Zahara, nine, from Ethiopia, said in a statement seen by The Hollywood Reporter: "It is inspiring to see such an important story so beautifully illustrated with such creative talent.
"It draws out the richness of Ethiopian culture and shows how important legal advances can be made while respecting local culture.
"It is a story that gives hope for Ethiopia's future, and for other countries where countless girls grow up without the protection of laws that shield them and their bodies, and shows how the courage of brave individuals can awaken the conscience of a society."
Angelia is currently directing Unbroken and previously directed In The Land Of Blood And Honey, while her producing credits include Maleficent.
