THE FIRST SEASON: Christopher Eccleston (SHALLOW GRAVE, EXISTENZ) plays the ninth incarnation of DOCTOR WHO, as with U.K. pop starlet Billie Piper playing the part of his companion, Rose, the Doctor embarks on yet more far-flung and improbable adventures: traveling 5,000,000,000 years into the future as the Earth is about to be swallowed by the sun, escaping from a mysterious space-station where the contestants are trapped in demented versions of popular reality-TV shows, and facing an old and terrible menace, the Daleks. THE SECOND SEASON: The BBC continues in its successful quest to rebrand the iconic DOCTOR WHO franchise with this second series of 21st-century episodes. The kitschy sets of old have been discarded, and David Tennant takes over from Christopher Eccleston as the 10th incarnation of the Doctor. Former pop star Billie Piper remains at the Doctor's side, playing his assistant, Rose, and a vast array of villains and intergalactic troublemakers face them as they zip through the galaxy in the Tardis. This time out, Queen Victoria and the Cybermen come face to face with Tennant's Doctor, and longstanding fans of the show will be delighted to see the robotic dog K9 returning.
