Winter is coming to “Doctor Who”: HBO’s “Game of Thrones” actress Maisie Williams is set to guest on an upcoming episode of the Peter Capaldi time-travel series, BBC America revealed on Monday.

“I’m so excited to be working on ‘Doctor Who’ as it’s such a big and important part of British Culture,” Williams said. “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.”

“We’re thrilled to have Maisie Williams joining us on ‘Doctor Who,’” Steven Moffat, the show’s head writer and executive producer, added. “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.”

Comedian and actor Rufus Hound (“Cucumber”) also joins the guest cast alongside Tom Stourton, Ariyon Bakare, Simon Lipkin, Ian Conningham, Murray McArthur, Barnaby Kay, John Voce, and Struan Rodger.

In addition to playing Arya Stark on “GoT,” Williams also recently starred in the one-off docu-drama “Cyberbully.” In February 2015, the young actress was awarded a Shooting Star Award at the Berlin Film Festival.

“Doctor Who” continues its filming with two period adventures: ‘The Girl Who Died’ written by Jamie Mathieson and Moffat, and ‘The Woman Who Lived’ by Catherine Tregenna.

Starring Capaldi as The Doctor and Jenna Coleman as Clara Oswald, “Doctor Who” sees the duo directed on their epic adventures by Ed Bazalgette (“Poldark”).
