Richard Graham Williams (24 May 1945 – 17 August 1990) was an English television producer, script editor and screenwriter. He produced three seasons of the BBC science fiction television series Doctor Who during Tom Baker's era as the Fourth Doctor, the ITV children's series Super Gran (1986–1987), and thirteen episodes of Tales of the Unexpected (1982–1984). Early work After working as the script editor for The View From Daniel Pike (1971), Sutherland's Law (1973), Barlow at Large (1975) and Z-Cars (1975–1976), he was encouraged by Bill Slater, then BBC Head of Serials, to move to production. He created a new police series for the BBC, which became Target, but the corporation's management decided to take him off it at an early stage and charged him with taking over Doctor Who in 1977, swapping roles with Philip Hinchcliffe. Doctor Who Williams was the producer on Doctor Who between 1977 and 1980, during the Tom Baker era. Under Philip Hinchcliffe, the series had "reached an almost unprecedented level of popularity", but also come under heavy criticism for its frightening and violent content, especially from Mary Whitehouse. Upon taking over the reins of the series, Williams was instructed by his superiors to tone down the violence. Williams himself thought Hinchcliffe had gone too far for a series that had a large audience of children, but said the BBC had been guilty of an overreaction in response. One of the notable early introductions to the series under the Williams tenure was the robot dog K9, which was part of his effort to aim the series more at younger viewers. Williams was also keen to introduce more humour into the series. During his period on the programme, Williams worked closely with three script editors: Hinchcliffe-era script editor Robert Holmes continued with Williams for a short while, but was succeeded by Anthony Read in his first season. Read remained as script editor for the following season, also known as the Key to Time, which introduced the character of Romana (Mary Tamm), but Douglas Adams (now best known for The Hitchhiker's Guide to the Galaxy) took over the role for his final year, season 17, which saw Lalla Ward replace Tamm as the regenerated Romana. Williams also wrote significant portions of the scripts for two stories beset by writing problems, The Invasion of Time (1978) and City of Death (1979).
