It isn't known what roles any of these actors will portray. Crooked House is based on the Agatha Christie novel of the same name, which hasn't been previously adapted for film or television. The story centers around the murder of a multi-millionaire and all of his family members who have cause to want him dead.
"The story has a couple of fresh sides to it that I didn't remember from Christie's work. There's a love story, which didn't feature strongly in many of her books, so that seemed very different to me and fresh. Plus it's quite morally ambiguous, which also appealed to me."
Production will start sometime this summer in the U.K., working from a $20 million production budget.
