Baltasar Kormakur’s The Oath has been picked up by Gunpowder & Sky for distribution, with plans for a U.S. theatrical release in the summer.

The film, which premiered as a Special Presentation in Toronto, was the number one box office film in Iceland in 2016.

Kormákur also stars in The Oath, the first time he has appeared in front of the camera in eight years. He plays a respected doctor living an ordinary life in a quiet suburb of Reykjavík. Things begin to spin out of control when his daughter introduces her dangerous and manipulative new boyfriend to the family. As the boyfriend’s grip tightens, the doctor makes a desperate decision that will change everything.

Produced by Kormakur’s RVK Studios, the film also saw festival play in San Sebastian, Busan, Santa Barbara, Chicago, Palm Springs, and elsewhere. “The Oath was a real passion project for me and RVK,” says Kormákur. “We’re thrilled to partner with Gunpowder & Sky who share our enthusiasm for the film. We look forward to the North American release.”
