"Northern Lights" (John Hanson and Rob Nilsson, 1978) is the story of the North Dakota farmers who founded the Nonpartisan League in the early 1900s. The League, a little known Populist movement, was organized by immigrant Scandinavian homesteaders. It existed on a platform of Socialist values. The film is framed as the reminiscences of Henry Martinson, the 94-year-old (at the time of filming ) real-life Nonpartisan League labor leader. For information, BasilicaHudson.com.
