Acorn Productions is planning two new Agatha Christie adaptations for BBC One.
The first is a new adaptation of Christie's most successful work "And Then There Were None" which Sarah Phelps will write. A Christmas 2015 airing is planned.
The second is a six-part adventure thriller series adaptation of the "Partners in Crime" short stories which feature husband and wife detective duo Tommy and Tuppence Beresford.
The 1950s-set project will star David Walliams as Tommy, whilst Tuppence has yet to be cast. James Warwick and Francesca Annis played the roles in the previous 1980s TV series adaptation.
Award winning playwright Zinnie Harris will pen the first three episodes. Both efforts are the first of a planned reinvention of the Agatha Christie brand across a range of platforms by Acorn Productions.
