Season "Four" starts next year-2008, but they are taking a year off before we see season "Five"! But at least it's confirmed that David Tennet will be sticking around! http://www.bbc.co.uk/pressoffice/pressreleases/stories/2007/09_september/03/who.shtml Doctor Who to return for fifth series in 2010 David Tennant to return to the Tardis After months of media speculation, BBC One can confirm that the Bafta-award winning Doctor Who will return for a fifth series in spring 2010. Viewers are in for a treat this Christmas, as a special episode starring David Tennant and Kylie Minogue will be broadcast on BBC One in December 2007. Series four, which went into production in July 2007, will hit UK screens in spring 2008 with a special episode for Christmas 2008. In 2009, Doctor Who will return with three specials starring David Tennant, with Head Writer, Russell T Davies. The full length fifth series will transmit in 2010. Jane Tranter, Controller, BBC Fiction, says: "Doctor Who is one of the BBC's best loved and most successful dramas. Its journey over the past three series has been one of the most ambitious and exciting that we have had, and I'm delighted to be able to confirm not only three exciting specials for 2009, but a fifth series in 2010." Menna Richards, Controller, BBC Wales, says: "The success of Doctor Who is a fantastic tribute to the dedication and expertise of the production team at BBC Wales who have worked on the project from the outset. This announcement is marvellous news for all involved, and more importantly for the programme's amazing fan base and audience. BBC Wales is looking forward to producing the fifth series." Following the critically acclaimed season three finale, the BBC has announced that Catherine Tate is set to return to the Tardis for the complete 13-week run of series four of Doctor Who, reprising her role as Donna from the 2006 Christmas special. Freema Agyeman, who won praise for her portrayal of Martha Jones in series three, is also set to return mid series four.
