Look out "Doctor Who" viewers -- fandoms will collide this Saturday in an episode titled "The Girl Who Died." The "Who" installment will guest star Maisie Williams, an actress best known for playing Arya Stark on "Game of Thrones." Williams' wardrobe might not look considerably different, as the fantasy actress will be playing a young citizen of a Viking village.
To psych fans up for Arya's adventure with the Doctor, the BBC has released a sneak peek at "The Girl Who Died," which features Williams' Ashildr teaming up with the Doctor's companion Clara (Jenna Coleman) to stop a very trash compactor-y dilemma. You can check out the sneak peek below. "Doctor Who," which is nearing the midway point of its ninth series, airs this Saturday at 9 PM ET on BBC America.
