K-9 and Company

K-9 and Company was a proposed television spin-off of the original programme run of Doctor Who (1963–1989). It was to feature former series regulars Sarah Jane Smith, an investigative journalist played by Elisabeth Sladen, and K-9, a robotic dog. Both characters had been companions of the Fourth Doctor, but they had not appeared together before. A single episode, "A Girl's Best Friend", was produced as a pilot for a proposed programme, but was not taken up. "A Girl's Best Friend" was broadcast by BBC1 as a Christmas special on 28 December 1981. The story was released on DVD on 16 June 2008 as a double pack with K-9's first Doctor Who story "The Invisible Enemy". Although a full series of K-9 and Company was not produced, the two characters did re-appear two years later in The Five Doctors, an episode of Doctor Who broadcast in 1983 celebrating the show's twentieth anniversary.
