Snakedance - S20-E2
Trivia: Brian Miller, who stars as Dugdale in this story, was the husband of Elisabeth Sladen, the actress who portrayed the Doctor's companion Sarah Jane Smith in the show from 1973 to 1976.
Trivia: The Doctor replaces the sprig of celery in his lapel with one conjured by the Eternals in this episode. The previous piece had been one he'd picked up in "Castrovalva", which was a Block Transfer construct created by Adric. This means that both pieces of celery were unreal constructs from artificial realities.
Trivia: Sylvester McCoy, although only credited as 1 Doctor, actually plays the 6th Doctor during the pre-titles sequence, making him the only actor to play two different Doctors.
Trivia: Commander Maxil is portrayed by Colin Baker, who would later succeed Peter Davison in the role of the Doctor.
Trivia: This was the final story to feature Roger Delgado in the role of the Master. He was killed in a car crash in Turkey less than three months after the story's sixth and last episode.
Trivia: During filming, Tom Baker (The Doctor) was bitten on the left side of his upper lip by a dog belonging to Paul Seed (Graff Vyda-K). As a result, publicity stills for "The Ribos Operation" saw Baker wearing a plaster on his face, and for the remainder of filming he required heavy and uncomfortable make-up application to cover the wound. The scar remained visible for much of Season 16.
Trivia: For many years, Episode Three of this story only existed in black and white, as the colour master videotape had been wiped by the BBC in 1976. It was eventually restored in colour and released on DVD in 2009.
Trivia: During production of this story, Peter Davison (The Doctor) and Janet Fielding (Tegan) announced their departures from the series. Producer John Nathan-Turner had offered Davison a fourth season in his role, but he feared being typecast if he stayed beyond three years on the programme.
The Caves of Androzani - S21-E6
Trivia: Robert Glenister (Salateen) had starred with Peter Davison in the BBC sitcom Sink or Swim, in which they played brothers Brian and Steve Webber.
Trivia: Colin Baker also provides the voice of a Jacondan at Freighter Control in part three of this story.
The Caves of Androzani - S21-E6
Trivia: This was the final regular appearance of Peter Davison as the Doctor and his favourite serial from his three years on the programme. Davison has said that if he were given more scripts like "The Caves of Androzani" earlier in his run, he might have been persuaded to stay for a fourth season.
Trivia: Of all the actors who have played the Doctor, Colin Baker is the only one to have been fired from the role.
Answer: TARDISes are generally available for properly authorised use on Gallifrey; they're not usually assigned to a particular Timelord on a long-term basis. The Doctor stole his when he left his homeworld.
