The Dad’s Army collection has a selection of production shots taken during filming along with photographs taken from special appearances, such as the Blue Peter shot above. Even more interesting are the letters from performers and agents showing how the cast was assembled including the agreement that Clive Dunn should enjoy third billing after Arthur Lowe and John le Mesurier.
Although much of the story told will be familiar from interviews and books, it is fascinating to see the original documents, most handwritten. It also underlines just how long ago this programme, that still feels so young and fresh, was made – almost 45 years now since its inception.
