Series 3
List of Doctor Who serials

The fourth series of British science fiction television programme Doctor Who began on 25 December 2007 with the Christmas special "Voyage of the Damned". Following the special, a regular series of thirteen episodes aired, starting with "Partners in Crime" on 5 April 2008 and ending with "Journey's End". "Partners in Crime" marked the debut of Donna Noble, as played by Catherine Tate, as a full-time companion to the Tenth Doctor. A short Children in Need special was also produced. The series started production on 8 August 2007 and concluded on 29 March 2008.

List of episodes[edit]

The concept of the "Doctor-Lite" episodes (which included "Love & Monsters" from Series 2 and "Blink" in Series 3), in which the Doctor plays a minimal part in the action of the story, was taken further in this series with the addition of a "Companion-Lite" episode; "Midnight" is a story primarily featuring the Doctor, with Donna only in scenes at the beginning and end of the episode, while "Turn Left" equally has the Doctor playing a minimal role, instead focusing on Donna.

Martha is abducted by the Hath shortly after the time travellers arrive. Rescuing Martha becomes the Doctor and Donna's main priority, as well as attempting to put a stop to the ugly war that has consumed the planet.

The Doctor and his companions prepare to do battle with Davros and the Daleks, who are out to destroy everything and everyone in the universe other than themselves.

The two Doctors, Donna, Jack, Rose, Martha, and Sarah Jane, along with Rose's ex-boyfriend Mickey Smith (Noel Clarke) and mother Jackie Tyler (Camille Coduri), attempt to foil Davros' plans to destroy reality itself. However, Donna has her mind wiped of all her adventures with the Doctor because otherwise the Time Lord knowledge will overwhelm and kill her. 

Supplemental episodes[edit]

"Time Crash" was filmed for the 2007 Children in Need appeal.

Main characters[edit]

The fourth series marked David Tennant's third and final full series as the Doctor (although he continued in the role for the 2009/10 Specials) and also featured a total of seven companions. In the Christmas special, Australian actress and singer Kylie Minogue starred as one-time companion Astrid Peth, who perished before the end of the episode. The companions in the regular series had all been in the lead companion role previously: the primary role of Donna Noble, who was introduced in "The Runaway Bride", was played by Catherine Tate for all thirteen episodes. Freema Agyeman, who portrayed the Doctor's companion Martha Jones in series three, returned for "The Sontaran Stratagem", "The Poison Sky", "The Doctor's Daughter", "The Stolen Earth" and "Journey's End". Billie Piper, who played Rose Tyler from the first episode of the new series to the finale of the second series appeared in the three final episodes of the series. She made brief appearances in the episodes "Partners in Crime", "The Poison Sky" and "Midnight". John Barrowman, Elisabeth Sladen, Noel Clarke and Camille Coduri, who portrayed previous companions Jack Harkness, Sarah Jane Smith, Mickey Smith and Jackie Tyler respectively, also reappeared in the finale.

Guest stars[edit]

Recurring guest stars for the series included Bernard Cribbins and Jacqueline King as Donna's grandfather Wilfred Mott and mother Sylvia Noble. Penelope Wilton returned as Harriet Jones in "The Stolen Earth", her first appearance since "The Christmas Invasion". Noel Clarke and Camille Coduri reprised their roles as Mickey Smith and Jackie Tyler in "Journey's End". Adjoa Andoh returned as Martha Jones' mother Francine in the finale. Eve Myles, Gareth David-Lloyd and Tommy Knight also starred in the finale in their respective roles of Gwen Cooper, Ianto Jones and Luke Smith from spin-off series Torchwood and The Sarah Jane Adventures. This marked their first appearances in Doctor Who itself, although Eve Myles had previously featured in "The Unquiet Dead" in a different role.

The fourth series featured a large number of high-profile stars such as Kylie Minogue (Astrid Peth in "Voyage of the Damned"), Alex Kingston (River Song in "Silence in the Library"/"Forest of the Dead"), Sarah Lancashire (Miss Foster in "Partners in Crime"), and Phil Davis and Peter Capaldi (Lucius and Caecillus respectively in "The Fires of Pompeii").[19] Other guest stars included Sasha Behar, Tim McInnerny, Colin Morgan, Christopher Ryan, Georgia Moffett (daughter of Fifth Doctor actor Peter Davison and current wife of David Tennant), Nigel Terry, Felicity Kendal, Fenella Woolgar, Colin Salmon, Lesley Sharp, Lindsey Coulson, David Troughton (son of Second Doctor actor Patrick Troughton), and Chipo Chung (who had previously portrayed Chantho in "Utopia").[20][21] Evolutionary biologist Richard Dawkins and Paul O'Grady made cameo appearances as themselves in "The Stolen Earth".[22]


After appearing in "The Runaway Bride" as a one off companion, Donna Noble became the doctor's companion for series 4.

Doctor Who had been recommissioned for a fourth series in March 2007,[23] shortly before the broadcast of the third series. The production schedule called for 15 full episodes to be produced, rather than the usual 14, due to the announcement that the next full series of Doctor Who would not air until 2010. This schedule meant that the programme would be unable to enter production during the second half of 2008. The 15 episodes consisted of 13 regular episodes and two Christmas specials. Recording for the 2007 Christmas special began on 9 July 2007,[24] with production on the series itself beginning on 8 August 2007[25] and concluding on 29 March 2008.[26] The tenth production block — consisting of 2008 Christmas special "The Next Doctor" and the BBC Proms "cutaway" scene "Music of the Spheres" — completed recording on 3 May.[27]

Doctor Who Magazine gradually revealed writers for the series alongside episode announcements. First-time writers for the show included James Moran, co-writer of the 2006 horror film Severance, and Keith Temple, who had written episodes of Byker Grove and Casualty. Previous writers Gareth Roberts, Stephen Greenhorn, Helen Raynor, Steven Moffat and Russell T Davies all contributed to the series, with Davies continuing to act as head writer and executive producer. Tom MacRae had written an episode for this series, entitled "Century House",[28] but this was replaced after Russell T Davies decided that it was too close in tone to Gareth Roberts' "The Unicorn and the Wasp".[29] This was Phil Collinson's last series as producer, as well as Russell T Davies and Julie Gardner's last full series as executive producers, all having worked on the programme since its return. Davies and Gardner continued their roles for the 2009/10 Specials. Susie Liggat produced five episodes (blocks 2, 5 and 7), as she did in series 3 with "Human Nature"/"The Family of Blood". Collinson received an executive producer credit for these episodes.

All of the episode titles were revealed in the 5 April 2008 issue of the Radio Times, except the title of the twelfth, which was "being kept secret as it gives away too much."[30] The article also identified the title of episode 9 as "River's Run", as did the press release for the subsequent issue of Doctor Who Magazine, but this was changed a few days afterwards to "Forest of the Dead". The title of episode 12 was eventually revealed in a press release as "The Stolen Earth".[31]

A Children in Need special, entitled "Time Crash", was produced alongside the series and was broadcast on 16 November 2007. In addition, a mini-episode entitled "Music of the Spheres" was shot on 3 May 2008[27] for series 4 and was premiered at the Doctor Who Prom on 27 July 2008, with the audio being broadcast simultaneously on BBC Radio 3. It was then broadcast on BBC One on New Year's Day 2009.

On 1 February 2008, the BBC announced that, in a partnership with Carlton Screen Advertising, a 90-second film trailer of the fourth series would be shown in cinemas across Britain "before the most anticipated new releases".[32] The trailer was aired on British television on 22 March 2008.[33] Three teaser trailers and one full length trailer consisting of unique footage were subsequently produced and aired on television and in cinemas promoting the fourth series.[34][35]

"You've got to watch and listen closely. It's been seeded for a long time, with small but vital references going all the way back to series One."

Russell T Davies[36]

Like the previous three series, all of the episodes are bound together in a loose story arc. In previous series, the story arcs were in the form of an arc word, such as Bad Wolf, Torchwood, or Mr Saxon, but the arc for the fourth series is cumulative: Doctor Who Magazine's preview of "Partners in Crime" described the arc as "an element from every episode–whether it's a person, a phrase, a question, a planet, or a mystery –builds up to the grand finale". Multiple mentions were made about the bees disappearing from planet Earth and stories driven by a missing or lost planet. Executive producer Russell T Davies stated in the same feature that the series' finale had been planned for three years previous to its airdate.[36] The regular series focuses heavily on Donna: David Tennant stated that the "whole thirteen weeks is Donna's story ... why she's with the Doctor again is the subtext",[37] and producer Phil Collinson cited Donna as a "fresh dynamic" for the fourth series.[38]

The forty-second trailer features Donna Noble, portrayed by comedienne Catherine Tate, sitting over a camp fire, talking about "creatures of metal, fire, and blood" threatening the universe as shots of the Daleks, Sontarans, and the Ood come into view. She talks about a man called the Doctor (David Tennant), who is portrayed in fleeting glimpses until his name is mentioned, who constantly saves the universe from these threats. Donna ends her narration by saying the Doctor will be back to save them and she will be ready to join him. The trailer ends with the Doctor and Donna simultaneously saying "and just like that, we'll be gone."
