There is something of the swings and roundabouts in this adaptation of the cracking BBC series. On the one hand, the feature length format allows us to develop more the Perry/Croft characters, on the other it removes some of the quickly-paced potency of the humour... Either way, though, it's still an hugely enjoyable watch that reconciles great sitcom writing from these two literal geniuses with a cast and scenario that delivers potent reminders of just how those "left on the shelf" determined to make a valuable contribution to the protection of their country against the Nazi scourge. It has the same cast as the television series, and depicts the formation of their unit under the command of nitwit "Capt. Mainwaring" (Arthur Lowe). The film has a more comically militaristic theme to it - they drill, eventually with firearms (not a great idea in their gas-powered, converted, butcher's van!) before they find themselves engaged in manoeuvres under the watchful eye of the slightly bumptious "Gen. Fullard" (Bernard Arched). Of course, just about everything goes wrong - but the humour is genuinely funny; the dialogue subtly enhances what we can not only see, but frequently anticipate - and that adds bundles to the enjoyment of this. Again, it swipes at the pomposity of the upper classes, the aspiration of a newly establishing middle class and of the industriousness of the chancer - expertly epitomised by "Hodges" - part time warden/greengrocer and black-marketeer "Pte. Walker" (James Beck). The film does rehash a little of the original innovation, but it's still a great spirited depiction of some really courageous folks who did their bit!
