Dad's Army is a BBC television sitcom about the British Home Guard during the Second
World War. It was written by Jimmy Perry and David Croft, and broadcast on the BBC from 1968 to 1977. The sitcom ran
for nine series and 80 episodes in total; there was also a radio version based on the television scripts, a feature
film and a stage show. Many of the TV episodes were remade for BBC Radio 4 with the original cast, although other
actors played Walker after James Beck’s death. These radio versions were adapted from the original television scripts
by Harold Snoad and Michael Knowles, and featured John Snagge as a newsreader, who set the scene for each episode.
Different actors were used for some of the minor parts: for example Mollie Sugden played the role of Mrs Fox, and
Pearl Hackney played Mrs Pike. The first episode was based on the revised version of events seen in the opening
of the film version, rather than on the TV pilot.
