Although the 1918 Finnish Civil War between Whites and Reds remained a controversial topic a century later in Finland, many Finnish filmmakers have taken up the subject, often basing their work on a book. In 1957, Toivo Särkkä's "1918", based on Jarl Hemmer's play and novel, was screened at the 7th Berlin International Film Festival. Recent films include Lauri Törhönen's 2007 "The Border", and Aku Louhimies's 2008 "Tears of April", based on Leena Lander's novel. Perhaps the most famous film about the Finnish Civil War is Edvin Laine's 1968 "Here, Beneath the North Star", based on the first two books of Väinö Linna's "Under the North Star" trilogy; it describing the civil war from the losing side, Finland's Red Guards.
