Dag Hammarskjöld, the Swedish diplomat who became Secretary-General of the United Nations, dedicated his life to peace and international cooperation. In this sweeping biographical drama, director Per Fly follows Hammarskjöld’s journey from his rise in international politics to his untimely death in a mysterious plane crash in 1961. Along the way, the film portrays the challenges he faced in balancing ideals with the harsh realities of Cold War geopolitics. Anchored by Mikael Persbrandt’s compelling performance in the title role, Hammarskjöld is a richly detailed portrait of a man whose vision for global peace remains strikingly relevant today.
