The diaries on which the book is partly based were edited by Alan Bishop and published as Chronicle of Youth in 1981. In 1998, the war letters which Brittain also drew on in her autobiography were published in an edition by Alan Bishop and Mark Bostridge. Entitled Letters from a Lost Generation, their appearance was met with considerable acclaim. Adaptations The book was dramatised by Elaine Morgan as a five-part serial which was transmitted on BBC2 in 1979. This version features Cheryl Campbell as Vera Brittain, Peter Woodward as Roland Leighton, Joanna McCallum as Winifred Holtby and Emrys James and Jane Wenham as Vera's parents. In 1998, to commemorate the eightieth anniversary of the Armistice, a fifteen-part radio dramatisation of the letters on which Testament of Youth was partly based was broadcast on BBC Radio Four. Entitled Letters from a Lost Generation, it was dramatised by Mark Bostridge and starred Amanda Root as Vera Brittain and Rupert Graves as Roland Leighton. 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.
