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.

Doctor Who: The Waters of Mars, will broadcast later this year on BBC One and BBC HD, more information on the special coming soon.
