There's something epic about their sheer existence - the last two survivors of an ancient race. It's a clash of the titans. Both of them, heading for death, and yet both determined to survive - at any cost!"

Davies and Tennant are passing the baton to Steven Moffat and actor Matt Smith, who will play the Eleventh Doctor in a new season of the re-imagined series premiering in 2010 on BBC AMERICA.
