Emiliano Granada Lead writer Cilla Jackert’s “Thin Blue Line,” a fresh take on a police procedural, is Sweden’s contender for the Nordisk Film & TV Fond Prize at 2021’s Göteborg Film Festival. Produced during a tumultuous time for police all around the world, the show quickly establishes itself as an intimate portrayal of the lives – both personal and professional – of its central characters who happen to be part of Malmö’s police.
