Aunt Sally was a role originally offered to actress and Carry On star Amanda Barrie, who turned it down. Pertwee asked Una Stubbs to take on the role: they had worked together in a 1975 production of Aladdin at the Richmond Theatre, and it was her dance and performance skills on that stage that caught his imagination. Like Pertwee, she was already a household name, having starred as Rita Rawlins in the hugely popular sitcom Till Death Us Do Part (and its various sequels) since 1965. According to Pertwee's memoir, his version of Worzel Gummidge was originally pitched as a feature film, which would have told the story of "the scarecrow equivalent of the Peasant's Revolt". Willis and Hall adapted the role of Worzel specifically for and around him, inspired by a postman character he played more than thirty years earlier in 1948's BBC radio comedy Waterlogged Spa, due to the actor's performance imbuing the character with a strong Devonshire accent.

The other key character was the Crowman, played by Geoffrey Bayldon. The Crowman created Worzel (and many other scarecrows besides), and as such is often used as a device to explain various plot contrivances as well as provide Worzel with a new head whenever one is needed. Bayldon was also already well known, especially to younger viewers, as the star of Catweazle from 1970 to 1971. The production was obviously high enough in calibre to attract some of the greatest actors of the era in guest parts. We especially enjoyed Beryl Reid, who pops up to play Worzel’s old mother (even though she was only a few weeks older than Pertwee). Connie Booth (Fawlty Towers) turns up as a rival to Worzel’s affections as another Aunt Sally, though this one is much kinder to him. There are recurring guest roles for Carry On stars Barbara Windsor (Saucy Nancy) and Joan Sims (Mrs Bloomsbury-Barton). Eager to take on the role, Pertwee encouraged Waterhouse and Hall to rewrite the script as a television series. They pitched the series to Head of Drama at the BBC, Shaun Sutton, and to Philip Jones at Thames Television, without success. All hope appeared to be lost, until Lewis Rudd at ITV regional broadcaster for the south east of England, Southern Television, heard about the show and enthusiastically commissioned it.A lot of the credit for the show's success must go to director James Hill. At the time of the series' conception, Hill was working with Pertwee's Doctor Who successor, Tom Baker, to get a feature film, Doctor Who Meets Scratchman (a story that, coincidentally, also featured scarecrows), off the ground. He and Pertwee got on famously and became lifelong friends. His stoic demeanour and strong work ethic guided the crew through an often gruelling production schedule, but he also established the aesthetic look of the series, with Worzel's grimy, believably earthy appearance contrasting with the bucolic beauty surrounding him.

But as much as he’d love to join his friends, Worzel can’t be seen wandering around by humans. He recalls the legend of a fairground with an enchanted organ. It’s believed that, with the right music, the organ has the power to send humans to sleep so that scarecrows can enjoy the rides without the fear of being seen.Worzel Gummidge had been created in 1936 by author Barbara Euphan Todd, who wrote ten books about the character, the final published in 1963. It was first adapted for radio in collaboration with actress and writer Mabel Constanduros: Barry Took once said of Constanduros that "although today her reputation has faded, she was a popular cultural figure between the wars, helping to establish the style and flavour of British radio comedy". The two later collaborated again to adapt the series for television in 1953's Worzel Gummidge Turns Detective (now long lost), with Todd writing the scripts. Frank Atkinson took on the title role.
