2013 specials

The '2013 Specials were a number of television stories that were written and produced to celebrate the 50th Anniversary of Doctor Who. Like the 20th Anniversary special, The Five Doctors, these specials are not considered to be part of a numbered season.

Overview
The 2013 Specials follow on from the final moments of The Name of the Doctor, in which Clara Oswald discovers the Doctor's greatest secret, a previously unknown incarnation.

The anniversary stories revolve around this incarnation, known as the War Doctor, and the final events of the Last Great Time War. The Christmas special follows on from Name by focusing on the Doctor's life on Trenzalore.

The specials also featured a number of the Doctor's regenerations, specifically those of the Eighth, War, and Eleventh Doctors. As such, the regenerations of all canonical Doctors have now been depicted on-screen.

Cast
The 2013 specials saw the end of Matt Smith's tenure as the Eleventh Doctor, and ended with his regeneration into the Twelfth, played by Peter Capaldi.

Celebrating the shows 50th anniversary, several of the specials also featured previous actors who had portrayed the Doctor. Paul McGann portrayed the Eighth Doctor on-screen for the first time since his initial portrayal in TV: Doctor Who, and David Tennant returned as the Tenth Doctor, and all other former actors were seen through the use of archive footage. The War Doctor was also played by John Hurt.

Although Jenna Coleman returned as sole companion Clara Oswald, Billie Piper returned to the series, but portrayed a representation of the Bad Wolf, rather than her regular character of companion Rose Tyler.

Tom Baker also played the role of the Curator, an enigmatic character who may or may not be a future incarnation of the Doctor.
