From The Daily Star:
(do not read if you want to remain in the dark…)
DOCTOR Who bosses are set to call back FOUR of the Time Lord’s favourite assistants – including Billie Piper – for a sensational showdown. The old cast members will be reunited to help the Doc fight evil Dalek creator Davros in an explosive finale to the next series.
Leading the way in the line-up will be Billie (Piper) as Rose Tyler along with the rest of the Tyler family; they will hook up with the Tardis traveler’s latest assistants Martha Jones and Donna Noble. Also on hand to help out the Doc will be his old companion Sarah Jane Smith as well as Torchwood boss Captain Jack Harkness. Even the Time Lord’s dog K-9 will make an appearance.
The TV source said: “This is the daddy of all shows. The writer Russell T Davies really wants to pull out all the stops for the finale next year.”

The series finales in Doctor Who have become more and more overblown each year.
In 2005 we had the Doctor fighting an army of flying Daleks in a TV broadcasting satellite, Rose undoing all of their damage and the Doctor regenerating.
In 2006 there were Daleks fighting Cybermen… not that you’d notice since this was sidelined for Rose’s departure.
2007 was the Master’s final destruction of 10% of the Earth’s population… and his iPod.
With the future of the program in the air and rumors of a feature film starring Tennant and Piper, producer Russel T Davies has decided to pull out every last stop and just go whole hog with the biggest and loudest finale yet.
If The Daily Star is right, that is.
The movie is about a traveling entertainer (played by Christopher Plummer) who sold his soul to the devil for immortality and later decides to re-negotiate his contract rather than lose his daughter (played by stunning model Lily Cole), resulting in an absurd contest with the horned one himself. The entertainer uses a trippy ‘imaginarium’ which allows the audience to choose between light and joy or darkness and gloom… which sounds more complicated than beer or wine to me.
