Series 8 (Doctor Who)

Series 8 of Doctor Who, consisting of 12 episodes, began airing on 23 August 2014, and ended on 8 November 2014. Filming began on 6 January 2014, and ended on 7 August of the same year. This was the first full series to feature the Twelfth Doctor, played by Peter Capaldi; he was joined by Jenna Coleman as Clara Oswald as primary companion throughout the entire run. Series 8 was the first series since Series 5 to be broadcast straight with no series split halfway through it. Executive producer and showrunner Steven Moffat revealed that this will be the normal format for all future series.

Cast
Series 8 saw the debut of Peter Capaldi as the Twelfth Doctor. Capaldi was announced in a live television special, Doctor Who Live: The Next Doctor, on 4 August 2013. The previous Doctor, Matt Smith, announced he was leaving on 1 June of the same year.

The new Doctor was joined by Series 7, Part 2's companion, Clara Oswald, as played by Jenna Coleman, in her first full series.

Samuel Anderson joined the cast as a new recurring character, Danny Pink, a fellow teacher at Coal Hill School. Although initially reported by media as being a new companion for the Doctor, in fact the character never actually took on an official companion role during the course of the season.

The Paternoster Gang returned, as well and they each used a sonic device designed in a Blue Peter competition in the series. Kate Stewart, Osgood and UNIT also appeared.

This series also saw the return of the Master, now in a female incarnation known as Missy.

Production
Brian Minchin, the new producer of the series, explained in the July 2013 issue of Doctor Who Magazine that "I have just spent a very happy few days meeting some scarily clever writers, and we have an incredible set of stories to work on. More adventures ahead!". In a May 2013 interview, Steven Moffat claimed that "the next season is plotted out."

The first readthrough for Series 8 was held on 17 December 2013. This was an unusually long lead time, as actual filming for the first episodes of Series 8 did not commence until 6 January 2014, with Capaldi filming his first scenes the next day. In a break from what was done with Christopher Eccleston, David Tennant and Matt Smith, the first episode filmed by Capaldi is also to be the first episode to be broadcast.

Steven Moffat has penned both the series opener, episode 4, and the two-part series finale, as well as co-writing on episodes 2, 5 and 6. Phil Ford wrote episode 2, Mark Gatiss did episode 3, Steve Thompson's script is for episode 5, and Gareth Roberts wrote episode 6 of the series.

Three new writers joined the series: Peter Harness (episode 7), Jamie Mathieson (episodes 8 and 9) and Frank Cottrell Boyce (episode 10).

Directors

Episode notes

 * This is the first series of the revived series that does not consist of 13 episodes, although Deep Breath and Death in Heaven were extended episodes at 76 and 56 minutes respectively.
 * Deep Breath, Into the Dalek, The Caretaker, Flatline and In the Forest of the Night all feature the appearance of a mysterious character known only as "Missy". This is analogous to the early appearances of Madame Kovarian in Series 6, and is the overall arc for the series. In Dark Water, Missy is revealed to be The Master.
 * This is the first series since Series 5 to end with a two-part story, and the first since Series 6 to have an officially-designated two-parter.
 * Two episodes have experienced censorship issues. BBC Entertainment serving SouthEast Asia announced it was required to delete a brief sequence from the region's broadcasts of Deep Breath showing Vastra and Jenny transferring oxygen by way of a kiss due to some jurisdictions prohibiting the depiction of same-sex kissing. On 4th September 2014, BBC One announced that a brief sequence in Robot of Sherwood was to be deleted from its broadcast on 6th September out of concern it might offend viewers in the wake of the recent execution of two Western journalists by terrorists.
 * This series is the first series since Series 3 not to feature River Song.
