more speculation and fact.....

The first episode, titled Smith and Jones is written by Russell T. Davies and features the Judoon, a "clan of galactic stormtroopers". Doctor Who: The Inside Story has concept art of a destroyed sonic screwdriver, indicating that his trusty tool may be destroyed or damaged in this story. Davies will also write episodes 3, 11, 12 and 13. A story to be written by Stephen Fry, originally commissioned for Series 2 but moved due to logistical issues, has been scrapped, apparently for lack of time on Fry's part. Euros Lyn returns to direct stories in the 2007 series, although it is not yet known which. Susie Liggat will take over the role and responsibilities of producer for a month while Phil Collinson takes a holiday. The second episode, set in 1599 London, will feature an appearance by William Shakespeare (played by Dean Lennox Kelly) and a plot to destroy the Earth. It is written by Gareth Roberts (long-time Doctor Who novelist who also wrote the TARDISODEs for Series 2 and Attack of the Graske. Scenes for this episode were filmed in Coventry, Warwick and at the recreated Globe Theatre in London. Other guest stars appearing in the first filming block include Roy Marsden, Anne Reid, Ardal O'Hanlon, Christina Cole, Jalaal Hartley and Sam Marks. Another episode will feature Thelma Barlow as a character named Lady Thaw, and Mark Gatiss as a scientist. Gatiss's appearance will make him the second person who has both written and acted in the show, and the first of the new series to do so. Another story will feature an alien race named the Plasmavores (described as "blood sucking aliens"). One story, set in 1930s New York -Daleks?, will feature Miranda Raison as a showgirl. Ryan Carnes has also been cast in one story, and Hugh Quarshie will play a character named Solomon in a two-part story. British tabloids have regularly reported rumours about plot elements in the third series, many of which have been denied by official sources. The Daily Mirror claimed that the Ice Warriors would return; Russell T. Davies has denied this, but has confirmed that there will be "a couple of returning monsters" in Series 3. Similarly, the BBC and Davies denied an August report in The Sun that the Rani would return in this series, played by Zöe Lucker. (This claim was repeated by The Daily Record in November.) The South Wales Evening Post has reported that in one episode, an alien disguised as a motorcycle courier will transport a London hospital to the moon, leaving only a crater in its place; Swansea's Singleton Hospital was used to represent the hospital in filming. Speaking at the MOBO Awards, Freema Agyeman confirmed "aliens on the moon". The Daily Star has reported that the third series finale will reveal that the Doctor has a son; this is supposedly intended to secure the future of the series if the Doctor dies after using up all of his regenerations. This has been denied by Davies and several other reliable sources. The News of the World has reported that the Daleks will return in the first two-parter, set in 1930s New York. This was confirmed by the cast at the Doctor Who edition recording of The Weakest Link at Pinewood Studios on Tuesday 21st November 2006.
