Doctor Who
Season 3
At twelve episodes, The Daleks' Master Plan was the longest story in the show's history until superseded by the fourteen-episode The Trial of a Time Lord in 1986. The season also had the greatest number of different companions (seven) and producers (three). This was the longest season in the history of the franchise to date, at 45 episodes. It also featured the first appearance of actor Nicholas Courtney, although not in his most famous role as the Brigadier. The Daleks' Master Plan also saw the return of Peter Butterworth as the Monk, who became the second Doctor Who enemy to make a return (after the Daleks themselves) to the show. This was also the season of The War Machines, to date the only televised story in which the taboo of never referring to the Doctor directly by the name "Doctor Who" is broken, with the exception of Missy's teasing in World Enough and Time.
