The Icelandic film-maker is in pre-production on the psychological thriller that he says will be “dark and foreboding and uneasy.”

Kormákur co-wrote The Oath with Olafur Egillsson and will co-produce with longtime producing partner Agnes Johansen with RVK Studios Banner.

Set in modern Iceland, the film is inspired by true events.

“I want to delve into an intimate, dark and psychological world where the characters are claustrophobic and tourmented,” said Kormákur. “There is no simple resolution. There is no defined summit. This story is dark and foreboding and uneasy.”

The director is currently in post-production on Everest, which Universal is set to release on September 18.
