Dad's Army is a British sitcom about the Home Guard during the Second World War. It was written by Jimmy Perry and David Croft and broadcast on BBC television between 1968 and 1977. The sitcom ran for 9 series and 80 episodes in total, plus a radio version based on the television scripts, a feature film and a stage show. The series regularly gained audiences of 18 million viewers and is still repeated worldwide.

The Home Guard consisted of local volunteers otherwise ineligible for military service, either owing to age or by being in professions that were exempt from conscription (Dad's Army deals almost exclusively with the former), and as such the series mainly featured older British actors, including Arthur Lowe, John Le Mesurier, Arnold Ridley and John Laurie. Among relative youngsters in the regular cast were Ian Lavender, Clive Dunn (who played the elderly Jones), Frank Williams, James Beck (who died suddenly during production of the programme's sixth series in 1973) and Bill Pertwee.
