Series 5 (Doctor Who)

Series 5 of Doctor Who, also known as Season 31 for clarity over Season 5, began its run on BBC One on 3rd April 2010 — almost 21 months after the last episode of the previous regular series. It was notable for being the debut series for Eleventh Doctor Matt Smith, and for introducing new companion, Karen Gillan's Amy Pond.

From a production standpoint, the series featured the largest number of staff changes since the BBC Wales version debuted in 2005. By far the most publicized was that of Steven Moffat's replacement of Russell T Davies as head writer, but whole departments within the production got new leadership, as well.

New production team
In the spring of 2008, it was announced that Steven Moffat, who has written Hugo Award-winning or nominated scripts for the revived series in each of its first four seasons and whose association with Doctor Who dates back to his writing of the Comic Relief parody The Curse of Fatal Death in the late 1990s, would succeed Russell T Davies as head writer and producer of the series. Davies officially retired from involvement with the series after the 2009 specials and at present has no plans to retain any direct connection to the series now Moffat's tenure has begun. However, Davies has announced that he plans to remain involved with production of Torchwood for the foreseeable future, and hopes to see further crossovers with Doctor Who, indicating he may not completely sever his ties with the parent show. Moffat has stated that no characters from the Russell T. Davies era will be returning in Series 5. 

Fellow executive producer Julie Gardner also departed at the end of 2009, and was replaced by Piers Wenger. Beth Willis was added as a third executive producer — giving the show three execs for the first time since Mal Young departed at the end of Series 1. The line producer of the series — a position once almost entirely held by Phil Collinson — was split between Tracie Simpson and Peter Bennett, two members of the production staff who had risen to prominence during the 2009 specials. For the first time since 2005, the series also credited a co-producer, Patrick Schweitzer, for episodes 6 and 10, the two episodes filmed in Croatia.

Other senior members of the production staff, such as production designer Ed Thomas and composer Murray Gold remained at their posts. However, several departments also underwent big changes beginning with The Eleventh Hour. Directors of photography Rory Taylor and Ernie Vincze — who between them had fairly evenly split responsibilities since 2005 — left along with Davies and Gardner. They were replaced by a series of individuals, each handling only one or two episodes of the series. Meanwhile, the costume department came under the leadership of Ray Holman, who replaced Louise Page, the longest-serving designer since the Hartnell era costumer Daphne Dare. The change, however, was not just the replacement of one individual with another, as Holman brought in members of his design company to fill junior positions in the costume department.

New numbering system?
The run-up to the broadcast of the series premiere was characterized by confusing and sometimes contradictory indications from BBC sources. According to Issue 410 of Doctor Who Magazine, the BBC intended to begin the numbering of seasons over again to reflect the change of production team. Thus, the 2010 season would ostensibly be marketed as "Series 1". A December 2009 announcement by the BBC regarding the show filming in Croatia also referred to the upcoming season as "Series 1." This seemed to be still further confirmed by phtographs of location filming, which clearly showed clappers labeled "Series 1". This suggested that, at least internally, the production team believed it was, indeed, a "first" series.

However, in early 2010, Steven Moffat indicated in Issue 418 of Doctor Who Magazine that this season will be referred to as Season 31. In his column in Issue 417, Moffat addressed the confusion in a humourous fashion, suggesting the season be called "Series Fnarg". "It's a whole new number," he wrote.

Muddying the waters even further, BBC Video announced on 3rd March 2010 that the first DVD release of episodes from the series, scheduled for issue in the UK in June 2010, will be titled Series Five, Volume 1.

As of late March 2010, it remained unclear exactly how the series was going to be marketed.

New TARDIS team
During his acceptance speech for the award for Best Drama Performance at the National Television Awards on 29th October 2008, David Tennant announced that he would not return for the 5th series. As the Tenth Doctor's companion, Donna Noble had been ostensibly written out at the time, Tennant's announcement set up the possibility that series 5 would begin with a completely new set of starring actors. Aside from the special case of Rose, the only reasonably analogous situation in the history of Doctor Who was the start of Jon Pertwee's first season.

On 3rd January 2009, during a special episode of Doctor Who Confidential entitled "The Eleventh Doctor", the BBC announced that Matt Smith would be playing the Eleventh Doctor. Smith succeeded Tennant in the last scene of The End of Time and Smith's Doctor was last seen crashing towards the Earth in a flaming, badly damaged TARDIS. That scene also confirmed that the Doctor would almost certainly sever connections with previous companions, making way for the introduction of new co-star Karen Gillan, who would play the character of Amy Pond.

New icons
In addition to the cast and crew changes, many of the other continuing elements of the show also underwent a major redesign at the start of the series. Most conspicuous was the 6th October 2009 unveiling of a new series logo — the first significant departure from the one that debuted on Rose. Likewise, the TARDIS herself got a noticeable exterior and radical interior make-over. British tabloid media reported the switch was due to the show's switch to high-definition production. Along with the TARDIS change came a substantially redesigned sonic screwdriver.

 * A number of websites have reported a rumor that the BBC was considering splitting the series into into two halves, the first half to air in the spring of 2010, and the second half to air later in the year.
 * According to the online resume of one of the show's crewpeople, part of one episode has been filmed in Croatia.
 * Soon after production began on Season 31, images of the new cast on location began to appear in the British media, revealing the Eleventh Doctor's costume, and apparent exterior changes to the TARDIS (most notably the reinstatement of a St. John Ambulance logo which once adorned the TARDIS during the First Doctor era. The media also revealed in July 2009 that Alex Kingston will again portray River Song. It was later said that she will appear in two episodes. It was announced in DWM Issue 417 that she'll appear in episodes four and five.
 * Adam Smith will direct one of the episodes block, Ashley Way will direct Chris Chibnall's two episodes (8 & 9) and Jonny Campbell will direct two (6 & 10).

Other Production Notes

 * Richard Curtis has stated that Series 5 (Series 1) will be broadcast in February but it has since been revealed that the series will be broadcast in April 2010.
 * Murray Gold confirmed in an interview that he would be staying on for Series 5, and that he would be composing a new theme.
 * On 17th February 2010, Matt Smith appeared on Blue Peter to choose the winner of a contest that asked viewers to design a TARDIS control console. The winning design is expected to be featured in some way in one of the final Series 5 episodes which is to be filmed in the spring of 2010.
 * The first four series were produced in association with the Canadian Broadcasting Corporation (accounts differ as to the extent of any financial support the CBC may have given, with the Doctor Who Information Network fanzine Enlightenment describing it more as an acquisition deal). Series 5 is the first full series to be produced since the end of this arrangement. It has not been reported whether any "co-production" arrangement has been established with another entity or whether Doctor Who is now fully BBC-produced.

Broadcast Dates
The BBC was unusually late in confirming the exact broadcast date for the start of the series. The first trailer to indicate a date said simply "Easter 2010", although there were reports of a variant of the trailer (later apparently withdrawn) with the 3rd April 2010 date. It wasn't until 24 March 2010 -- 10 days before broadcast -- that the BBC officially confirmed 3rd April, although Steven Moffat had indicated this during an interview on BBC Breakfast as early as 19 March.

Both BBC America in the US and Space in Canada have announced their broadcasts of Series 5 will commence on 17 April 2010.

Australia's ABC network has also announced it will air the new series starting on the 18th of April, 2010. This marks the first time all of the major markets for Doctor Who will see a new series within the same month.

Two weeks prior to its scheduled BBC America broadcast, The Eleventh Hour is scheduled to be screened on 3 April during the 2010 WonderCon in San Francisco.

There will be a week long delay between two episodes broadcasted in Europe. This is due to the Eurovision Song Contest being broadcasted one Saturday. In 2009 there were also reports that the BBC might split the season to accommodate its coverage of the FIFA World Cup; as of March 2010 there has been no announcement that such a split is expected.

Trailers
The first trailer (a series preview) was released on 1st January 2010 It featured several scenes from the upcoming series with several new and old enemies present throughout the trailer.

A 3D trailer promoting the series was released in trailers prior to Alice in Wonderland. . It featured the Doctor and Amy Pond lying on grass, gazing at the stars. Suddenly, the ground opens up and they fall into a blue twisting tunnel whilst within the tunnel they are confronted by Weeping Angels, Daleks, and a Smiler before they return atop the grass. A large snake-like head bursts through the screen at the end of the trailer. The effects and grading of the trailer were completed by The Mill.

A new trailer was released on the 19th March, the opening shot of which features Amy floating in space, with the Doctor in the TARDIS holding onto her by her ankle. Among other things it featured the Daleks, a Cyberman advancing on Amy, the Doctor on horseback, a dogfight in space between a Dalek Saucer and WWII Spitfires, and the Weeping Angels. The BBC America trailer, released the same day, contains additional footage not seen in any of the UK trailers.

Rumours

 * Neil Gaiman would be writing an episode of Series 5. Although this turned out not to be the case, Gaiman subsequently announced that he would be writing an episode of Series 6.
 * In DWM Issue 397, Steven Moffat wrote the "Production Notes" feature. This consisted mainly of an anecdote about how he became the head writer but he also touched upon his plans for Season 31. In particular he wrote "Piers Wenger and I are hard at work on Season 31. I can tell you nothing of our plans (except, obviously, THEY'RE BACK!)". Some have interpreted "they" to refer to the Time Lords, who had been "killed off" as a race during the Davies era. However, others have interpreted this as simply referring to the Daleks, who have become notorious for returning at least once a series since the revival. In a radio interview on 15th December 2009, Steven Moffat confirmed the return of the Weeping Angel; whether these are the species in question that are back is unknown.
 * It is unlikely that this means the Time Lords as they were brought back in DW: The End of Time and dealt with. In his book REF: Doctor Who: The Writer's Tale - The Final Chapter, Russell T. Davies indicated that he checked with Moffat before writing his script to see if Moffat had plans to return the Time Lords. Moffat's response "take them" would suggest the Time Lords are not returning in the near future.
 * The official BBC trailer for Series 5 includes footage of a Dalek, plus an episode entitled Victory of the Daleks has now been announced.
 * Despite the above, the speculation as to whether "They're back" refers to the Time Lords may intensify with the announcement in September 2009 of a Blue Peter contest in which entrants are being asked to design "a TARDIS console" to be used within the series, which could be interpreted as referring to a TARDIS other than the Doctor's. At the time of the contest's launch in early October, however, the contest description suggested that the console should look like "something the Doctor put together" suggesting a different storyline possibility.
 * Sophie Okonedo is rumoured to be playing a character called "Liz Ten", who is actually Queen Elizabeth X of a far-future United Kingdom.. The character is also refered to the Masked Lady in DWM.

Episodes Rumours

 * Episode 7 of the series is rumoured to have Amy pregnant, but it's part of a strange dream and she can't work out what is real and what's not.
 * Episode 8 and 9 are rumoured to be called 'Cold Blood' and 'The Ground Beneath Thier Feet'. It is thought to feature the Silurians.
 * In an interview with the Perthshire Advertiser, actress Neve McIntosh stated that she is playing Silurian twins in episodes eight and nine, which are rumored to be titled "The Ground Beneath Their Feet" and "Cold Blood".
 * Episode 11 guest stars James Corden, which features the Doctor, cut off from both Amy and the TARDIS, and left stranded on Earth. The episode also features the Doctor playing football. It is rumoured that this episode will be based on a Doctor Who comic strip The Lodger. It is also rumoured that this episode will be a Companion-lite episode with Amy not appearing fully. There are also pictures online from filming this episode showing Amy bringing a plate of fish outside of the Tardis and the Doctor lunging at it.
 * Episode 12 of the series is rumoured to be titled "The Pandorica Opens" and is rumoured to feature the Daleks, Cybermen and Sontarans and various old and new enemies.
 * This theory explains Christopher Ryan's casting as one "Commander Strak". Sonataran's names are often 5-letter words with S in the front, so Ryan may indeed play a Sontaran.
 * Dalek Operators and Nicholas Briggs, the Dalek's voice actor, were spotted filming in a museum.
 * A Cyberman made a brief appearance in a new trailer. Series5cyberman.jpg
 * It is unknown which old enemies will be returning, the Ice Warriors, Sea Devils, Autons, Axons, Slitheen, Yeti and Zygons are among the old enemies that could return.
 * The Silurians might appear in the finale after their two part episode.
 * Episode 13 is rumored to be titled "The Big Bang".
