This book is a comprehensive exploration of 90 years of film and television adaptations of the world’s best-selling novelist’s work. Drawing on extensive archival material, it offers new information regarding both the well-known and forgotten screen adaptations of Agatha Christie’s 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and debates that surrounded many of these screen projects – something that is brought to life through previously unpublished correspondence from Christie herself and a new wide-ranging interview with her grandson, Mathew Prichard. Agatha Christie on Screen takes the reader on a journey from little known silent film adaptations, through to famous screen productions including 1974’s Murder on the Orient Express, as well as the television series of the Poirot and Miss Marple stories and, most recently, the BBC’s acclaimed version of And Then There Were None.
