The Doctor (Doctor Who)
Jodie Whittaker took over the role as the Thirteenth Doctor in the 2017 Christmas special. In addition to the above-listed actors, others have played versions of the Doctor for the duration of particular storylines.
Notably, John Hurt guest starred as the War Doctor in the closing moments of the 2013 episode "The Name of the Doctor", the webcast "The Night of the Doctor" and the 50th Anniversary episode "The Day of the Doctor". The War Doctor is an incarnation existing between those of McGann and Eccleston. Hurt was never the programme's lead actor; his Doctor was retroactively inserted into continuity for the programme's 50th anniversary, and was written so as not to disturb the ordinal naming of the established Ninth, Tenth and Eleventh Doctors. In the 1986 serial "The Trial of a Time Lord", Michael Jayston played the Valeyard, an amalgamation of the Doctor's darker sides from between his twelfth and final incarnations.
Rory Williams
Rory Williams is a fictional character portrayed by Arthur Darvill in the long-running British science fiction television series "Doctor Who". Having been introduced at the start of the 5th series, Rory joins the Eleventh Doctor (Matt Smith) as a companion in the middle of Series 5. As Amy Pond's fiancé, Rory is initially insecure because he believes Amy secretly loves the Doctor more. Later, however, he proves to be a hero in his own right and he and Amy get married. The couple conceive a daughter aboard the Doctor's time machine, the TARDIS, while in the time vortex, but their baby is kidnapped at birth. In "A Good Man Goes to War", Rory and Amy discover their time-traveler friend River Song is actually their daughter Melody Pond. The Doctor and River marry in "The Wedding of River Song", and Rory becomes the Doctor's father-in-law.
In "The Angels Take Manhattan", the fifth episode of the seventh series, he and Amy are transported back in time by a Weeping Angel, leading to the couple's departure from the series.
