The Next Doctor
The status of the 2008 Christmas special The Next Doctor is a matter of debate. Officially, it has been called the 14th episode of Series 4, however as noted below, the 4th series numbering also applies to the specials. Conversely, The Next Doctor was produced during the same production block as Series 4, and also was produced differently than the specials, which were shot in high definition. It remains to be seen if over time The Next Doctor becomes accepted as a 4th season episode, as one of the 2009 specials, or as a complete standalone.BBC Video has also announced that it will be included in the forthcoming Specials box set on DVD and Blu-Ray, placing it with the 2009 Specials; in the past, BBC Video's titling and programming has come to be considered definitive.

Mini-Episodes

 * In May 2009, a BBC talent competition series hosted by John Barrowman entitled Tonight's the Night, ran a viewer contest; the grand prize being the opportunity to play an alien villain in a Doctor Who mini-episode written by Russell T. Davies. The resulting production was more of a skit, with David Tennant and Barrowman appearing out of character. Davies wrote in Doctor Who Magazine that he intended to write a more canoncial story, but chose not to; he attributed the title Tonight's the Night to the mini-episode. It is not considered officially part of the 2009 specials, but it was filmed during production.

Filming
Filming of Planet of the Dead commenced in mid-January 2009 and concluded in February. Production of The Waters of Mars began late January 2009, and finished in mid February. Production of the final specials was completed by late spring 2009.

Series Numbering
Although it was initially thought that the "interval" season of specials might come to be known as Series 5, or Series 4.5, however at present it appears that the BBC will not be assigning a series "number" to the specials, much as the previous Christmas specials and mini-episodes do not technically belong to any particular season. This, however, is contradicted by Russell T Davies himself in his book The Writer's Tale, where he calls The Next Doctor the fourteenth episode of the fourth series (likely due to the fact it was produced during the production of Series 4).DWM confirmed the specials would be coded 4.14, 4.15, 4.16 etc. Also, the BBC iPlayer page for The Next Doctor on its Christmas Day release stated the episode was part of 'Series Four'.

Writers
Russell T Davies is solely writing only the Christmas 2008 special and two others. One of the specials will be co-written by Gareth Roberts, and one will be co-written by Phil Ford. These particular specials will be historic in that they will be the first two episodes of the BBC Wales production of Doctor Who to formally credit a co-writer. With the inclusion of Ford, 2009 will mark the fifth straight year that Doctor Who has included at least one new writer for the show, and make Ford the only writer other than RTD himself to write for Torchwood, The Sarah Jane Adventures and Doctor Who.

Confirmed

 * Initial rumours that one of the specials would be filmed in Dubai, United Arab Emirates were confirmed in late January 2009 when BBC News reported that a bus intended for use in location filming for Planet of the Dead in Dubai was damaged. A related rumour, referenced in the Dubai-based newspaper 7DAYS, citing an unnamed BBC source, indicated that filming for one of the specials would occur in the United States.
 * Supposedly, Donna Noble, Wilfred Mott and the Master are all meant to return for at least one of the 2009 specials. This is rumoured because in the Series 4 Box-Set, a clip of Donna hearing the TARDIS disappear could be heard and a ring on her finger was shown quite visibly for a number of seconds. This clip was cut from the final cut. Throughout Journey's End and The Stolen Earth, clips of a ring on Donna's finger are seen. This refers back to the ring that was seen in Last of the Time Lords and could have some connection between the Master and Donna.
 * Although initial media coverage of the "gap year" indicated that all the specials would air in 2009, with Tennant's announcement of his pending departure in October 2008 came media references (yet to be officially confirmed) that the final special, and the final episode to feature Tennant, may not air until early 2010. Julie Gardner has confirmed that the first special will be broadcast during the Easter Holidays.
 * According to an interview by Russell T Davies in SFX Magazine, at least one of the specials will feature the Ood and possibly tie in with the closing scene of Planet of the Ood, and that the four specials that make up the gap year will form a loose arc, with the final two being a two-parter closely linked to the second special.
 * The Daily Mirror reported that an Episode will be set on Mars. With the Doctor having to battle aliens from Mars. This could possibly mean the Ice Warriors will be in one of the specials, or possibly the Sycorax as they were involved in an incident regarding a British expedition to Mars in The Christmas Invasion.
 * Similarly, rumours abound that Bernard Cribbins is reprising the role of Wilfred Mott, with guest star Jessica Hynes in one of the later specials, although claims that they have been seen "on set" on 21 March would appear to be unfounded given that production of Special 2 did not even begin until March 30. On 3rd April John Simm was seen on set, leading many to speculate that The Master will return. Recent images released on several websites indicate that Simm will return, (though they do not confirm that he is returning as the Master,) as well as showing Timothy Dalton wearing garb reminiscent of the Time Lords.
 * On 17th May 2009, the newspaper News of the World reported that Billie Piper would reprise her role as Rose Tyler for the 2009 Christmas Special, and that episode would be the last one to feature David Tennant as The Doctor. That episode will air on New Years Day when Matt Smith's tenure as the Eleventh Doctor will begin. The article can be seen on the link.
 * Timothy Dalton will appear in the final two episodes. He is rumoured to be playing The Monk, as he was seen on set in Time Lord costume.
 * David Tennant has revealed that the final two specials will be set not just on Earth. The Ood Sphere has been confirmed as one of these settings as the Children in Need preview is set on the Ood Sphere. Gallifrey is rumoured to be one of the other settings in this story.

Unconfirmed

 * It is rumoured that News Reporter Trinity Wells, played by Lachele Carl, who has appeared in every series, since series 1, will appear. Davies said in an interview that The Doctor may meet her and she may sacrifice herself for the Earth.
 * Rumours of past characters returning (though most of these remain new series character) have extended to the rumour that, just like the Fourth and Fifth Regenerations, characters influential in the Tenth Doctor's life will make brief cameo returns, including a rumour of the Fifth Doctor in the (reconstructed) old TARDIS console room set. (In some previous regenerations, previous characters have returned and, in many cases, said "Doctor", either in flashback or cameo)
 * Fans have speculated and it may have been said by the script writers (evidence needed) that River Song will witness the regeneration of David Tennant into Matt Smith.
 * Given the Master's psychic ability, and the appearance of the low-intelligence Ood, a storyline may be that the Master has control of them, and is using them against the Doctor. The News of the World article, in the rumour above, shows a picture of the Doctor stumbling with Ood Sigma, with red-eye standing nearby staring at the Doctor.
 * Claire Bloom has been reported by some media as appearing as The Doctor's Mother in the final special, with her manager cited as one source. Members of The Doctor's family will return/appear. . As of late November 2009, the BBC has not confirmed this officially.

Proved to be False

 * The Sun newspaper in the UK reported Paul McGann is to make an appearance as the Eighth Doctor in one of the specials. However, on 12 September 2008, the BBC refuted this allegation, saying, "There is no truth to the story at all." However, a brief clip of McGann as the Doctor did appear in The Next Doctor as part of a recap of all of the Doctor's incarnations.
 * Actor Patrick Stewart may also appear in the 2009 specials, playing the renegade Time Lord, The Monk. At least one (possibly made-up) source believes that "the BBC has offered him the role and are willing to wait for Stewart's schedule to clear".  Stewart could therefore appear in either the specials or the 2010 series. Unlikely as when it comes to Doctor Who the newspapers tend to make up their own rumours which are completely untrue.
 * Two mini-episodes (Children in Need Special and Time Crash) and two interactive mini-episodes (the online game Attack of the Graske and the audience-participation Music of the Spheres) have been produced since Tennant joined the series; the possibility exists that another mini-episode may be produced during the Specials season, although as of January 2009 there has been no indication of this.
 * Recurring rumors include speculation that either Georgia Moffett will return as Jenny, the Doctor's daughter, or that River Song, introduced as a future companion of the Doctor's in Series 4, will return (though spin-off speculates relates as to whether Alex Kingston would return of if a younger actress would be cast). Both have also been cited as potential companions in Series 5, too.
 * In late January several media outlets reported that Freema Agyeman would reprise the role of Martha Jones in one of the specials; this is highly unlikely as Russell T Davies intends, with Donna losing her memory, Rose having found a half-human Doctor in a parallel universe, Martha having forged a life of her own outside the TARDIS, and Sarah Jane and Captain Jack still in The Sarah Jane Adventures and Torchwood, the 2009 specials will see the Doctor travelling alone, with no references to former companions.
 * The Sun newspaper has also reported that one of the specials would be entitled "Beautiful Chaos" and Bernard Cribbins would guest star; meaning that the Mandragora Helix could return in an apparent adaption of the novel.
 * Media reports in mid-April 2009 stated that Gillian Anderson had been cast in either one of the specials, or possibly in one of the early Matt Smith episodes of Series 5.
 * The Nimon may return in one of the specials as hinted by Russell T Davies in an excerpt from The Next Doctor Podcast.
