After last night's transmission of Planet of the Dead, the title of this year's second special episode of Doctor Who was revealed. We now know that the episode will be called 'The Waters of Mars' and a trailer was also shown after Planet of the Dead's credits had finished broadcasting. The trailer was approximately twenty three seconds in length and it can be viewed in full here on this site below;

The Waters of Mars is scheduled for transmission in Autumn later this year and it has been written by both Russell T Davies and Phil Ford. David Tennant will reprise his role as the 10th Doctor in the episode and he will be joined by Lindsay Duncan who will play his companion Adelaide. All filming work for the episode, which was directed by Graeme Harper, has now been completed and more information about The Waters of Mars will be posted here on this site as soon as it becomes available.
