A couple of other suggestions:
– ‘The King’s Choice’ (2016), a tense, realistic and well-cast film about the first two days of the Nazi invasion of Norway in 1940
– ‘Kon-Tiki’ (1950), the documentary film about Norwegian explorer Thor Heyerdahl’s spectacular voyage across the Pacific on a balsa raft (a film securing Norway an Oscar)
– ‘Kon-Tiki’ (2012), an action-packed remake of the film mentioned above
– ‘Falling Sky’ (2002), a drama comedy about mental problems featuring Kristoffer Joner (the hero of the later successes ‘The Wave’ and ‘The Quake’)
