Doctor Who: The Girl Who Died Photos Released

The BBC has released new photos from this week's episode of Doctor Who, titled "The Girl Who Died."

In "The Girl Who Died," captured by Vikings, the Doctor and Clara must help protect their village from space warriors from the future, the Mire. Outnumbered and outgunned, their fate seems inevitable. So why is the Doctor preoccupied with a single Viking girl?

In addition to Peter Capaldi as the Doctor and Jenna Coleman as Clara Oswald, "The Girl Who Died" features the highly anticipated guest star role by Game of Thrones' Maiisie Williams, as the Viking girl Ashildr.

Check out the photos below.

Doctor Who airs Saturdays at 9 p.m. ET on BBC America.
