Series 4 (Doctor Who)

The 2009 Specials were broadcast between the end of Series 4 and the beginning of Series 5. Four specials have been broadcast at various points in 2009. Of the four specials, one has so far aired at Easter 2009, followed by a second that aired in November. The two remaining specials aired to air on Christmas 2009 and then in New Year 2010. These four 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 star David Tennant. For the 2009 Specials, the Doctor was traveling alone, each episode stared a one-off companion. There had been conflicting reports given as to why the decision was made to take a year off. Initial media reports suggested that this was in order to allow David Tennant to perform a season of Shakespeare during the time a regular season would have normally entered production. However, these reports are directly contradicted in Russell T Davies' book Doctor Who: The Writer's Tale, which contains correspondence from the spring of 2007 -- months before the gap year plan was announced -- in which Davies indicated that the intent was to take the series off for a year, except for a few specials, in order to allow a new production team to make its transition, as Davies had already informed the BBC that he would not executive-produce a fifth season.

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.
