Michael Gambon on the set of Dad's Army in October 2014. Filming took place on the beach at North Landing, Flamborough, East Riding of Yorkshire, England.The scene involved German soldiers shooting from behind their landing craft at Captain Mainwaring's platoon, who were hiding behind 'concrete' anti-tank emplacements on the beach. Godfrey appeared to be using a leather leg brace or splint as a make-shift loudhailer in order to address the attacking Germans. Digiscoped image taken from cliff top high above film set
