Rufus Sewell (The Man In The High Castle, Victoria) has been set as the lead in The Pale Horse, BBC One's upcoming two-part Agatha Christie adaptation from Mammoth Screen and Agatha Christie Limited. 
BBC One has set The Pale Horse as their next Agatha Christie adaptation. It follows in the footsteps of previous adaptations And Then There Were None, The Witness For The Prosecution, Ordeal By Innocence and The ABC Murders. 
BBC One has released a first look image of John Malkovich in character as Hercule Poirot in their upcoming three-part Agatha Christie adaptation The ABC Murders. The ABC Murders is set in 1930s Britain and follows Poirot as he faces a serial killer known only as A.B.C. As the murder count rises, the only clue is the copy of The ABC Railway Guide at each crime scene. Poirot’s investigations are thwarted at every turn by an enemy determined to outsmart him. If Poirot is to match his nemesis then everything about him will be called into question; his authority, his integrity, his past, his identity. 
The BBC has found their Poirot. John Malkovich (Being John Malkovich, In The Line Of Fire) has been set to star as the legendary Belgian detective in BBC One's three-part Agatha Christie adaptation The ABC Murders. BBC One has pacted with Agatha Christie Productions Ltd for seven further adaptation of classic Christie titles, TVWise has learned. The first project being pursued under this seven project commitment is Ordeal By Innocence.
