The episode starred Matt Smith as the Eleventh Doctor and Jenna Coleman as his companion, Clara Oswald. Previous lead actors David Tennant and Billie Piper returned for the episode, Tennant reprising his role as the Tenth Doctor, while Piper portrayed a sentient doomsday weapon called the Moment, projected as an image based on her character Rose Tyler. She is invisible and inaudible to everyone but the War Doctor (John Hurt). Other appearances included a very brief glimpse of the then-upcoming Twelfth Doctor (Peter Capaldi), who would succeed Matt Smith in "The Time of the Doctor", and a guest appearance by Fourth Doctor actor Tom Baker, in his late 70s. Rounding out the guest cast were Joanna Page as Queen Elizabeth I and Jemma Redgrave as Kate Stewart, the daughter of 1970s central figure Brigadier Lethbridge-Stewart. The special also featured the return of the Daleks and the Zygons, shape-shifting aliens who had previously appeared only in Terror of the Zygons (1975).
