“In 2013, something terrible is awakening in London’s National Gallery; in 1562, a murderous plot is afoot in Elizabethan England; and somewhere in space an ancient battle reaches its devastating conclusion. All of reality is at stake as the Doctor’s own dangerous past comes back to haunt him.”
The episode is due to air on Saturday 23 November, the same day the show debuted in 1963, and stars Matt Smith, David Tennant and Jenna Coleman with Billie Piper and John Hurt.
