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.
Matt Smith (actor)
Matthew Robert Smith (born 28 October 1982) is an English actor. He is well known for his roles as the eleventh incarnation of The Doctor in the BBC series "Doctor Who" and His Royal Highness The Prince Philip, Duke of Edinburgh, in the Netflix series "The Crown". Smith initially aspired to be a professional footballer, but spondylolysis forced him out of the sport. After joining the National Youth Theatre and studying Drama and Creative Writing at the University of East Anglia, he became an actor in 2003, performing in plays like "Murder in the Cathedral", "Fresh Kills", "The History Boys", and "On the Shore of the Wide World" in London theatres. Extending his repertoire into West End theatre, he has since performed in the stage adaptation of "Swimming with Sharks" with Christian Slater, followed a year later by a critically acclaimed performance as Henry in "That Face".
