Following the success of the three-part version of Agatha Christie's And Then There Were None on BBC One in December, the corporation is developing an adaptation of her short story The Witness for the Prosecution with the same producer and screenwriter, Mammoth Screen and Sarah Phelps.
In 2014 the BBC announced it would be the new TV home of Agatha Christie in the UK for the 125th anniversary of her birth, thanks to a major deal with her estate. Their first commissions were the excellent Partners in Crime (regrettably axed) and the adaptation of And Then There Were None.
Last June, ITV acquired Mammoth Screen.
