Renowned for her role as Arya Stark in the international fantasy drama series Game of Thrones, Williams said: “I’m so excited to be working on Doctor Who as it’s such a big and important part of British culture. I can’t wait to meet the cast and crew and start filming, especially as we’ll be shooting not too far from my home town.”
Steven Moffat, lead writer and Executive Producer, added: “We’re thrilled to have Maisie Williams joining us on Doctor Who. It’s not possible to say too much about who or what she’s playing, but she is going to challenge the Doctor in very unexpected ways. This time he might just be out of his depth, and we know Maisie is going to give him exactly the right sort of hell.”
The show continues filming with two period adventures – The Girl Who Died by Jamie Mathieson and Steven Moffat, and The Woman Who Lived by Catherine Tregenna, directed by Ed Bazalgette (whose work can currently be seen on BBC One’s Poldark).
Comedian and actor Rufus Hound, who recently appeared in the series Cucumber, also joins the guest cast alongside BBC Three’s Siblings and CBBC’s Horrible Histories star Tom Stourton, Ariyon Bakare, Simon Lipkin, Ian Conningham, Murray McArthur, Barnaby Kay, John Voce, and Struan Rodger.
