Never Too Old...unseen documents and pictures from the BBC's archives
On 31 July 1968, TV viewers met a group of elderly soldiers and a "stupid boy" for the very first time.
Dad's Army became an instant classic with its gentle humour, nostalgia and pride in the men who gave their all for Britain, despite their limited means.
This new collection contains many items not available to the public until now, including candid post-war letters from the actors as they began their careers and internal BBC memos that show just how popular the series was right from the start.
A photo gallery also looks at the stars of the show from the first episode to the last, as well as taking a peek behind the scenes.
