World War II, The Home Guard, the New Dad's Army Film and the Spy.

Imagine the scene.  Children dressed as evacuees, on a school trip to the Seven Valley Railway.  They're happily waving flags and singing at the top of their voices,"Who do you think you are kidding Mr. Hitler?" Launched in 1968, the BBC TV series Dad's Army has brought WWII to another generation ensuring that the work of the Home Guard is remembered!

In 1939 Civil Defence plans were introduced to combat the threat of mass bombing and enemy occupation of Britain.  This included the distribution of 38 million gas masks to protect the Home Front against enemy attacks using poison gas. Local Defence Volunteers later became the Home Guard and then became known as Dad's Army, guarding the country against a threatened invasion.  Keeping watch over our coastline, public buildings, roads and railways, they also brought in enemy pilots who had baled out of damaged aircraft. Many of these volunteers had seen action during WWI and the Home Guard became a professional uniformed army equipped with weapons.
In October this year filming began on the new Dad's Army film which is set towards the end of WWII.  The discovery of a radio transmission from Walmington-on-Sea to Berlin reveals the existence of a spy.  Captain Mainwaring and his platoon are on hand to deal with this threat! Will this new remake capture the magic of the original TV show? Don't panic! With Toby Jones as Captain Mainwaring, Bill Nighy as Sgt. Wilson and Catherine Zeta Jones playing a glamourous journalist and lots of other stars including Bill  Paterson, and Tom Courtney  - it promises to be an entertaining film. It's also keeping history alive!
