Doctor Who will return to BBC One on November 15 with The Waters of Mars.

David Tennant returns as the Doctor in The Waters of Mars, the second of four Doctor Who specials being screened on BBC One this year. He is joined by his cleverest and most strong-minded companion yet, Adelaide Brooke, played by acclaimed British actress Lindsay Duncan.

Adelaide is head of Mars Base and doesn’t take kindly to an uninvited appearance by the Doctor. Peter O’Brien, star of Neighbours, Flying Doctors and Casualty, also guest stars as Ed, Adelaide’s second in command.

When asked how this TV special differs from others, David Tennant told reporters:

“It tells a different sort of story, I think, and it’s a long time into the episode before The Doctor takes control. That’s what’s unnerving about it – it’s not the standard structure. We expect The Doctor to take control earlier – we expect The Doctor to know how he’s going to do it and how he’s going to win through and he doesn’t. Even though he wins in the end it’s a bitter sweet victory. People die. That’s part of the story we have to tell to go where we’re going.”

Doctor Who: The Waters of Mars is written by both Russell T Davies and Phil Ford and is directed by Graeme Harper.
