Two stars. Unrated. In Norwegian and German with subtitles. 133 minutes. Norway was pulled into World War II when Germany invaded the previously neutral country on April 9, 1940. But conventional warfare there lasted only two months, until Norway surrendered to the Nazis on June 10. “The King’s Choice” looks, with a microscope, at those first couple of days of occupation, skirmishing and confusion. No one in this slow-moving Norwegian drama, which has been shortlisted for a 2017 Oscar nomination for best foreign-language film, seems more confused — at least initially — than Norwegian King Haakon VII (Jesper Christensen) who, as the story begins, is shown to be a slightly befuddled old man with a bad back, playing with his grandchildren.
