Series 4 (Doctor Who)

The 2009 Specials will be broadcast between the end of Series 4 and the beginning of Series 5. Five specials will be broadcast at various points in 2008-2009. Of the five specials, one has been scheduled for Christmas 2008, one for Easter 2009, and one for Christmas 2009, leaving the other two unscheduled. These five specials will be overseen by Russell T Davies and Julie Gardner, but traditional line producer, Phil Collinson, will not be returning for them. All will reportedly star David Tennant.

David Tennant announced that after the 2009 specials he would leave Doctor Who. Rumoured actors to replace Tennant are James Nesbitt, Robert Carlyle , David Walliams (who is the leading choice) , Harry Lloyd , David Morrissey (who previously played Jackson Lake in the 2008 Christmas special) and Paterson Joseph. Bill Nighy has stated he would love to take over from Tennant once he leaves if the producers approach him

For the 2009 Specials, the Doctor will be traveling alone, each episode starring a one-off companion.

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 ect.

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.

Rumours

 * 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."
 * Actor Patrick Stewart may also appear in the 2009 specials, playing the renegade Time Lord, The Monk. At least one 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.
 * In a recent issue of Doctor Who Magazine, Russell T Davies confirmed that the title of the first special will be revealed at the end of the The Next Doctor. It consists of four words, and one of them begins with a 'D'. In the credits of The Next Doctor, the title of the next special was revealed as Planet of the Dead
 * The Nimon may return in one of the specials as hinted by Russell T. Davies in an excerpt from The Next Doctor Podcast. It is possible that they will appear in Planet of the Dead, since a characteristic of the Nimon is that they are parasitic and use up a planet's resources.
 * It is rumoured that News Reporter Trinity Wells, played by Lachele Carl, who has appeared in every series, since serise 1, will appear. Russel said in an interview that The Doctor may meet her and she may kill herself for the Earth

Broadcast dates
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 (Unlikely). Julie Gardner has confirmed that the first special will be broadcast during the Easter Holidays.
