Starring as the Doctor is David Tennant and he will be joined by: Georgia Moffett (The Doctor's Daughter) though she is not playing Jenny, her character is called Cassie Rice; the voice of Bernice Summerfield, Lisa Bowerman (Survival); and the legendary David Warner (Tron, Time Bandits). Warner is also no stranger to Doctor Who having played the Time Lord himself in a 2003 audio play (reprising the role in 2008).
The writer for Dreamland is Phil Ford who is one of the few to pen stories for the triumvirate of Doctor Who, The Sarah Jane Adventures and Torchwood. His Who story, The Waters of Mars (due to be broadcast in November), was co-written with Russell T Davies. Directing the project is Who stalwart Gary Russell.
In this month's Doctor Who magazine, RTD hints that a third special project might be on the way (David Tennant's appearance in The Sarah Jane Adventures being the first), he says: "... it would be nice to round things off with a Special Project 3... I can promise, it's worth waiting for!"
