The Brit has signed up to star as Fred West, who was charged with murdering at least 11 girls, and burying many of their remains at his home in Gloucester, England in the 1970s. West committed suicide while awaiting trial in 1995, his accomplice wife Rosemary is currently serving a life sentence for her part in the gruesome crimes.
The Hollywood actor will take on the macabre role for a new programme, Appropriate Adult, on Britain's ITV channel, which will tell the story of West's life from his arrest up to his death.
Oscar-nominee Emily Watson will play voluntary worker Janet Leach, who sat in on police interviews, while stage actress Monica Dolan will portray Rose West.
The show will air in the U.K. later this year (11).
