Dad's Army the much loved BBC comedy series of the late 60s and early 70s is to be made into a film. The reason this is much loved is because the audience 20 years after the WW2 remembered it, they may have been in the Home Guard, they would likely have been in the armed forces, they understood the subtext and nuances the period. I was a child when the show was on and loved it, partly because my parents did, and partly because they could explain some of the jokes to me. Why was Mainwaring the captain and Wilson the sergeant when Wilson had the better service record? Why was Godfrey held in such esteem when he was "only" the medic? What was a fuzzy wuzzy? What does ARP stand for?
This was funny then but its time has passed, current film watchers have no context for the action, no recollection of the original or context for most of the jokes. The shows themselves have not always aged well and the films made with the original cast did not transfer well to the big screen. I fear this will be an unmitigated disaster.
