'The Marvellous Mrs. Maisel' actor joins a host of talent, including Kaya Scodelario, Bertie Carvel, Sean Pertwee, Henry Lloyd-Hughes, Poppy Gilbert, Madeleine Bowyer and Claire Skinner for the production from BBC One, Mammoth Screen and Agatha Christie Limited.

'The Pale Horse' follows Sewell's character Mark Easterbrook as he tries to uncover the mystery of a list of names found in the shoe of a dead woman. His investigation leads him to the peculiar village of Much Deeping, and The Pale Horse, the home of a trio of rumoured witches.

The two-part drama is being directed by Leonora Lonsdale and produced by Ado Yoshizaki Cassuto.

Filming has begun in and around the Bristol area for the show, which has been adapted from Christie's book by Sarah Phelps.

Tommy Bulfin, BBC Drama Commissioning Editor, said: "We are thrilled that filming is now underway on 'The Pale Horse' for BBC One. Sarah's brilliant scripts and her unique take on the famous Agatha Christie stories have once again attracted an array of top and exciting talent."

James Prichard, Executive Producer and CEO of Agatha Christie Limited, added: "This adaptation feels like nothing we have done before. This is a very different story from most that my great grandmother wrote, and Sarah has taken it to new heights. The cast, with the likes of Rufus Sewell and Bertie Carvel, is superlative, and it should be a highly entertaining drama."

And Helen Ziegler, Executive Producer for Mammoth Screen, said: "Sarah Phelps has excelled herself with her fifth adaptation of Agatha Christie's work. 'The Pale Horse' is a stunningly atmospheric, bewitching and thrilling piece, which has attracted the most wonderful stellar cast. We are utterly thrilled to see Sarah's brilliant writing be brought to life by director Leonora Lonsdale, the fantastic production team and incredible cast."
