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, said: “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."

Filming for The Pale Horse is underway in and around Bristol. The series is expected to air Christmas 2020.
