Question: What is the population of the country in which Darma was born? Passage 1:In 2009 it was announced that the feature film Testament of Youth was in development by BBC Films and Heyday Films producer David Heyman, and was to be directed by James Kent. This had the support of the Vera Brittain Estate, Brittain's daughter Shirley Williams, and Brittain's biographer Mark Bostridge who is acting as consultant. Saoirse Ronan was cast to play Brittain in 2012 but was replaced in December 2013 when it was announced that Alicia Vikander would play Vera Brittain in the film which was released in late 2014 as part of the First World War commemorations. On 4 February 2014 Kit Harington joined the cast to play the role of Brittain's fiance Roland Leighton. On 13 February 2014, Colin Morgan, Taron Egerton, and Alexandra Roach were announced to have joined the film's cast. An ensemble cast was later confirmed as filming began, including Dominic West, Emily Watson, Joanna Scanlan, Hayley Atwell, Jonathan Bailey and Anna Chancellor. It substituted Merton College, Oxford in the scenes showing Brittain's time as a student at Somerville College, arguing that filming in Somerville itself would been too difficult in light of the new buildings constructed there since the film's time period.
Passage 2:In 2004, Mendler got her first acting role in the animated Indian film The Legend of Buddha, in which she portrayed Lucy. When she was 13 years old, she got an acting role as a guest star on the soap opera General Hospital. She portrayed the dream child of character Lulu Spencer, in which the two have an argument on Mendler's character's birthday. The scene, lasting just under a minute, is later revealed to be a dream. That same year, Mendler was the voice of the character Thorn in the video game Bone: The Great Cow Race, which was based on the Bone comic series. In 2007, Mendler made her film debut in the film adaption of the Alice series, titled Alice Upside Down. Mendler starred alongside Disney Channel actress Alyson Stoner and Lucas Grabeel. Mendler portrayed the antagonistic role of Pamela, who is the rival of Stoner's character, Alice. For the film's soundtrack, Mendler provided backing vocals on the song "Free Spirit", performed by Stoner. Also in 2007 Mendler auditioned for Sonny with a Chance for the role of Sonny Munroe, but Demi Lovato was chosen. In 2008, it was announced that Mendler would play the role of Kristen Gregory in the film adaption of the popular teen novel series The Clique by Lisi Harrison. Mendler had the role of Kristen, a girl who attends OCD on a scholarship, and works hard to keep her good grades.
