on Joan Littlewood's play of the same name, Oh! What a Lovely War (1969); Spielberg's 2011 war drama War Horse was based on Michael Morpurgo's children's novel of the same name. Many of the films promoted as "documentaries" added context to authentic battlefield scenes by staging critical events, and invented episodes and dialog to enhance excitement at the cost of authenticity. Finnish Civil War 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. Spanish Civil War The Spanish Civil War has attracted directors from different countries. Sam Wood's For Whom the Bell Tolls (1943), based on Ernest Hemingway's book of the same name, portrays the fated romance between an American played by Gary Cooper and a partisan played by Ingrid Bergman against the backdrop of the civil war. The epic 168-minute film with its landscapes shot in Technicolor and a "beautiful" orchestral score was a success both with audiences and with critics. Alain Resnais's Guernica (1950) uses Picasso's 1937 painting of the same name to protest against war. Carlos Saura's La Caza (The Hunt, 1966) uses the metaphor of hunting to criticise the aggressiveness of Spanish fascism. It won the Silver Bear for Best Director at the 16th Berlin International Film Festival in 1966. Ken Loach's Land and Freedom (Tierra y Libertad, 1995), loosely based on George Orwell's Homage to Catalonia, follows a British communist through the war to reveal the painful contradictions within the anti-fascist Republican side. Korean War Samuel Fuller’s The Steel Helmet (1951) was made during the Korean War (1950–1953). The critic Guy Westwell notes that it questioned the conduct of the war, as did later films like The Bridges at Toko-Ri (1954) and Pork Chop Hill (1959). Fuller agreed that all his films were anti-war.
