‘Dad’s army’ is the home guard and its leader is Captain George Mainwaring. In a very small town in England, a band of merry misfits makes up its corps. Deep into WW2, all the fit, young men are away at war while the rejects and the elderly make up the home guard, charged with parading around and doing exercises and not much else.
Sergeant Arthur Wilson (Bill Nighy) assists Captain Mainwaring (Toby Jones) in their not much else; they mostly spend their days blending into the scenery. Literally. So when a beautiful woman (Catherine Zeta-Jones) arrives in town, they and the whole town are ripe for some shaking up. Rose is an intoxicating distraction until it turns out there’s an actual German spy in town and the home guard is too busy thinking dirty thoughts about Rose to notice his intelligence gathering, let alone catch him.
Dad’s Army is made up of the very best in old British guys – Tom Courtenay and Michael Gambon among them. It’s cute and silly in an old, doddering way. The movie is just as inoffensive and harmless as the elderly members of the home guard. Apparently this is the movie version of a beloved TV show that I never knew existed. Old fans wouldn’t recognize this iteration but it’s pleasant enough. Yes, that’s a tempered endorsement. Adjust your expectations and you may find it perfectly enjoyable. It’s not steak and caviar. It’s oatmeal. Good old reliable oatmeal.
