Sidekick K9 returns to Doctor Who.
Robot dog K9 will be reunited with Doctor Who in the new series after 24 years apart, say the show's producers. K9, who helped Tom Baker's Time Lord between 1977 and 1981, will join new Doctor David Tennant for one episode. The show, to be screened on BBC One next spring, sees the team investigate sinister events at a modern-day school. It will co-star Buffy the Vampire Slayer actor Anthony Head and Elisabeth Sladen, who is returning as 1970s Doctor's assistant Sarah Jane Smith. K9 and Sarah Jane will join the Doctor and his current sidekicks, Rose and Mickey, in a fight against the evil Krillitanes. Producer Phil Collinson said it was "great" to be welcoming back K9. "A whole generation fondly remember him as an ever faithful companion and best friend to Tom Baker's Doctor," he said. "I hope the new generation of viewers will fall in love with him in the same way."
