Following Tennant's late 2008 performance in a Royal Shakespeare Company production of Hamlet, four further one hour specials are to be shot in January 2009. One of these is scheduled to be shown at Easter 2009; another on Christmas Day.

Russell T. Davies will write two of the 2009 specials, and co-write the others; one with Gareth Roberts, the other with Phil Ford. Davies and Roberts previously co-wrote the Sarah Jane Adventures episode "Invasion of the Bane". Ford has previously written episodes of Torchwood and The Sarah Jane Adventures. This will be Ford's first Doctor Who script, making him one of few to have contributed to all three series.

Series 5 (2010)

The programme will return in 2010 with a fifth full series. For this fifth series, Russell T Davies will be replaced as head writer and executive producer by Steven Moffat.[16] Tennant, who has played the main character of the show for the past three series, stated on The Andrew Marr Show in June 2008 that he hasn't yet been asked to reprise the role for the fifth series, but he will consider it if asked, By July 2008, Russell T Davies said in The Guardian that Tennant had made his decision and the BBC knew what it was.

On 27 November 2007, it was confirmed that Billie would reprise her role as Rose Tyler in the fourth series for three episodes. Later, it was confirmed by Russell T Davies in Doctor Who Magazine that this return had been planned since she left.

It was also revealed in the 'Turn Left Doctor Who Confidential' that she had made arrangements to return as Rose since deciding to leave and had lied to journalists when she claimed that she would never return. The series began in April 2008, and after several cameos, Piper made her official return as Rose in the series four final episodes: Turn Left, Stolen Earth and The Journeys End.

She has not said whether she will be reprising the role again, although on Doctor Who Confidential she said that she thinks "It's never really the end for the Doctor and Rose" but it probably was "for the foreseeable future".
