Danish director Soren Kragh-Jacobsen will start shooting political thriller Det som ingen ved (literal translation: What No One Knows) on Feb 19. The eight-week shoot will take place in Denmark and Sweden.

The project will star Anders W. Berthelsen, who starred in the director's Mifune as well as in another Danish political thriller, King's Game. Danish actress Ghita Norby also stars with Norway's Maria Bonnevie.

The script, written by King's Game's Rasmus Heisterberg, follows a young man who suspects that his father's work for the Danish Defence Intelligence Service led to his sister's drowning.

Nimbus Film is producing with Lars Bredo Rahbek Hepp Film in Sweden and Danish TV 2 co-producing. The budget is said to be about Euros 3m.

The thriller is something of a departure for Kragh-Jacobsen, who got his start in family films before making 1999's Mifune, a Dogme romantic comedy that sold well internationally.
