This book is a comprehensive exploration of 90 years of film and television adaptations of the worlds best-selling novelists work. Drawing on extensive archival material, it offers new information regarding both the well-known and forgotten screen adaptations of Agatha Christies stories, including unmade and rare adaptations, some of which have been unseen for more than half a century. This history offers intriguing insights into the discussions and debates that surrounded many of these screen projects - something that is brought to life through previously unpublished correspondence from Christie herself and a new wide-ranging interview with her grandson, Mathew Prichard. <i>Agatha Christie on Screen</i> takes the reader on a journey from little known silent film adaptations, through to famous screen productions including 1974s <i>Murder on the Orient Express</i>, as well as the television series of the Poirot and Miss Marple stories and, most recently, the BBCs acclaimed version of <i>And Then There Were None</i>.
