“Game of Thrones” star Maisie Williams will appear in the new series of “Doctor Who.”

    The BBC hasn’t announced which part she’ll play, but lead writer Steven Moffat says, “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.”

    She says she’s looking forward to filming the show 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,” she says.

    Bristol-born Williams has played Arya Stark in the fantasy drama “Game of Thrones” since 2011.

    Stark is a young girl from a noble family who brandishes a sword and is often mistaken for a boy.

    She’s only 17, but she’s a three-time Screen Actors Guild Awards nominee. In February she was given a Shooting Star Award at the Berlin Film Festival.

    She won the 2013 BBC Radio 1 Teen Award for best British actress.

    Williams has starred in the one-off docu-drama “Cyberbully” and was one of the leads of Carol Morley’s BBC drama “The Falling.”

    Series nine of the relaunched “Doctor Who” returns to BBC One this autumn.

    Two period adventures are being filmed — “The Girl Who Died” written by Jamie Mathieson and Steven Moffat and “The Woman Who Lived” by Catherine Tregenna.

    “Doctor Who” is one of BBC One’s most highly regarded dramas, with 7.4 million people globally watching the last series.
