The marathon will begin with the pilot, "Invasion of the Bane," at 9 a.m. Eastern, followed by the ten half-hour episodes of the show's first season.
The Sarah Jane Adventures stars Elisabeth Sladen as Sarah Jane Smith, one of the most popular companions from the original series of Doctor Who (she assisted the Third and Fourth Doctors from 1973 to 1976). In season 2 of the new series Sladen was brought back for the instant classic "School Reunion," in which she encountered the Tenth Doctor (David Tennant). "School Reunion" was so well received that plans immediately commenced to spin off Sarah Jane in a more family-friendly series to air on the BBC children's network, CBBC (counteracting the violence and overt sexuality of Doctor Who's other spin-off, Torchwood).
The show also stars Yasmin Paige as Maria Jackson, Sarah Jane's 13-year-old neighbor, Tommy Knight as a boy named Luke, who is adopted by Sarah Jane at the conclusion of the introductory story, and Daniel Anthony as 14-year-old called Clyde Langer. Sarah Jane also has a powerful computer called Mr. Smith, voiced by Alexander Armstrong.
After the 60-minute pilot film, season 1 was made as five two-part half-hour stories. Season 2, comprising six two-part stories, began airing in September 2008 in Britain; a third season will air next autumn. Sarah Jane, Luke, and Mr. Smith appear in the final two episodes of season 4 of Doctor Who, "The Stolen Earth" and "Journey's End".
