The novel was written in 1957, and Yorkshire Television wanted David Jason to play Pop Larkin. He had never read the book so he went away and did so before accepting the part, and pronounced it a charming read, as well as lovely, but not much happened and didn't go anywhere. But the characters were strong, especially Pop Larkin, and he would be fun to play. Jason's only condition was to shoot the series on film, because he didn't want it to be a studio production. At least on film, it would look good, and have some quality about it, even if nothing happened.
Sidney Charles 'Pop' Larkin:
This calls for a cocktail!
