Special

Airs Saturday December 19, 9/8c.

David Tennant returns as The Doctor in The Waters Of Mars, the second of four Doctor Who specials to premiere on BBC AMERICA in 2009 and early 2010. He is joined by his cleverest and most strong-minded companion yet, Adelaide, played by acclaimed British actress Lindsay Duncan (Rome, Under the Tuscan Sun). Adelaide is head of the Mars Base and doesn't take kindly to an uninvited appearance by The Doctor. Peter O'Brien (X-Men Origins: Wolverine, Casualty) also guest stars as Ed, Adelaide's second in command. The Waters Of Mars is written by Russell T Davies and Phil Ford, directed by Graeme Harper, and executive produced by Russell T Davies and Julie Gardner.
