In 1978, a television adaptation of Worzel Gummidge was produced by ITV station Southern Television for transmission on the ITV network. It was written by Keith Waterhouse and Willis Hall, and starred former Doctor Who actor Jon Pertwee as Worzel and Una Stubbs as Aunt Sally, a life-size fairground doll and the object of Worzel's affection. This was a significant change from the original books, where Aunt Sally is Worzel's aunt, and Worzel is married to Earthy Mangold, a character who does not appear in the series. The Crowman, who made Worzel and some of his other scarecrow friends, is played by Geoffrey Bayldon, who is better known for playing the title role in the show Catweazle. Regular and occasional guest appearances were made by well-known TV actors of the time, including Barbara Windsor, Billy Connolly, Bill Maynard, Joan Sims, John Le Mesurier, Jimmy Jewel, Lorraine Chase, Bernard Cribbins, Connie Booth, Thorley Walters, Jonathan Cecil, David Lodge, Mike Reid and Beryl Reid.
According to Jon Pertwee's memoirs, the idea for the series began as a proposed film about the Worzel Gummidge character by Waterhouse and Hall which would have been "about the scarecrow equivalent" of the Peasants' Revolt, with the scarecrows rising up against farmers who were going to burn them when the farming season had finished. Pertwee was approached to play the lead character by producer Gareth Wigan. When that project was unable to secure the funds it needed for a distribution deal, Pertwee encouraged the writers to create a television pilot instead, and via his agent pitched the idea to Shaun Sutton, then Head of Drama at the BBC. Sutton turned down the project, which he felt was "too way out", as did Philip Jones at Thames Television. Pertwee later recalled that he "began to lose faith in the project", but Southern Television's Lewis Rudd heard about it and enthusiastically agreed that his company would make the series.
A total of four series with 30 episodes and an extended Christmas special were made between 1979 and 1981. When Southern lost its contract to broadcast on ITV, the new contract-holder, TVS, did not renew the show, despite a press campaign led by the Daily Star. Unsuccessful attempts were made to continue the series: one for it to be produced independently by Southern for the BBC, and another for it to be produced in Ireland, HTV continued with their plans to produce the show in Ireland, but they fell through because of trade union problems, as did attempts by the same company to make further episodes in England. However, the scripts that Waterhouse and Hall had written for the Irish episodes were published in book form. In 1981, Pertwee and Stubbs starred in the musical Worzel Gummidge at the Birmingham Repertory Theatre, which also starred Lucy Benjamin (then Lucy Jane Baker) as Sue. 's final TV appearance as Worzel was in 1995, to celebrate 40 years of ITV.
