The BBC's adaptation of Agatha Christie's Ordeal by Innocence, the Argyll family is trying to move on after the brutal murder of their mother and the arrest of her adopted son for the crime – but as new information emerges, is he guilty after all?
The cast is packed with top British acting talent, from Bill Nighy to Eleanor Tomlinson to Matthew Goode. Here's who they'll be playing – and where you've seen them before:
Bill Nighy – Leo Argyll
Who is Leo Argyll? Eighteen months after his wife was violently murdered, Leo Argyll is preparing to marry his obnoxious (yet attractive) secretary Gwenda. His four surviving children – all adopted – are gathered together for the celebrations.
Where have I seen Bill Nighy before? Bill Nighy's acting career stretches across five decades and includes The Men's Room, Love Actually, Pirates of the Caribbean, Harry Potter, and The Hitchhiker's Guide to the Galaxy.
Anna Chancellor – Rachel Argyll
Who is Rachel Argyll? Rachel is our murder victim: within the first minutes of the first episode, she's lying on the floor in a pool of blood. A wealthy heiress, she and her husband Leo adopted five children after realising that they couldn't have biological kids – but, as their flashbacks reveal, she wasn't always the loveliest of mothers and could be extremely cruel. Her son Jack was found guilty of her murder and died in prison, but new information throws that verdict into question.
