EXCLUSIVE: Everest director Baltasar Kormakur is stepping in front of the camera for the first time in eight years to take The Oath. The multi-hyphenate returns to acting with the psychological thriller he co-scripted with Olafur Egilsson and is also helming and producing. He’ll play a father who sets off on a mission to try to pull his daughter away from the world of drugs and petty crime, only to discover that danger can be found in unexpected places. He’s currently shooting the Icelandic-language drama.

Kormákur, who continues to segue between Hollywood and his home country of Iceland, originally trained as an actor and last appeared onscreen in his own Reykjavik-Rotterdam in 2008.
