1980 was a year of significant change for Doctor Who. The previous three years had been some of the most turbulent of the shows history, with ever shrinking budgets, razor sharp deadlines and the all too real threat of industrial action having forced the cancellation of the final story of season seventeen. In a bid to alleviate some of his workload, producer Graham Williams had suggested to Head of Serials Graeme McDonald that it would be beneficial to create a new Associate Producers position, and that his Production Unit Manager John Nathan-Turner would be a prime candidate for the job. Ultimately nothing became of his suggestion, and when in 1979 Williams announced that season seventeen was to be his last, he once again put forward Nathan-Turner’s name as his possible successor.
McDonald’s first choice for the producers position was ex Production Unit Manager George Gallaccio who had previously worked on the show under Philip Hinchcliffe, and had gone on to produce the BBC supernatural drama series The Omega Factor. Gallaccio declined McDonalds offer and the job went to Nathan-Turner.
Following a merger of the Series and Serials departments, and his promotion to overall head of department, McDonald found himself with precious little time to devote to individual programmes, and mindful of Nathan-Turners inexperience, brought in Barry Letts in the capacity of Executive Producer. Letts job would be to offer advice and support on scripts and to approve major production decisions, formalising an arrangement previously discharged by the head of department.
Around the same time Script Editor Douglas Adams, who had struggled with the pressures of his other work commitments had also elected to leave. A number of potential candidates were considered including Johnny Byrne, who would go on to write The Keeper of Traken, The Arc of Infinity and Warriors of the Deep, but the job ultimately went to Christopher H Bidmead. Bidmead had been critical of the direction taken by the show in recent years, and had taken some persuasion to join the production team, but he was much heartened when he discovered that Nathan-Turner and Letts shared his views, and agreed with his vision of a show with stories based in science.
Another of the production team’s decisions was to tone down the jokiness that had become prevalent over the past three seasons, and to reign in their leading mans ad-libbing. Under Graham Williams, Tom Baker had enjoyed a greater than normal level of input into the shows production, and would often change his lines and insert new ones if he felt the scene merited it. This policy would prove unpopular with Tom, and early on into the production of season eighteen, the actor finally decided to relinquish the role at the end of his current contract.
Major competition for John Nathan-Turner’s first season came in the shape of glitzy American sci-fi import Buck Rogers, which had been slotted directly opposite Doctor Who in ITV’s Saturday evening schedule, and is most likely the main cause of season eighteens poor viewing figures. Meglos in particular was watched by a mere 4.7 million viewers, the lowest figure since 1966.
