As well as original episodes of the BBC show still being aired to this day, the popularity of the comedy has resulted in two films and the modern spin-off Dad's Army: The Lost Episodes, which saw Gavin and Stacey's Mathew Horne and Friday Night Dinner's Tom Rosenthal star in a series of episodes missing from the original broadcast.
While the spirit and humour of Dad's Army continues to live on today, the original stars of the show have sadly passed on. Take a look through the gallery to see the original cast and celebrate their work…
Captain Mainwaring - Arthur Lowe
Taking the lead role of Captain Mainwaring was Arthur Lowe. Arthur's role as the pompous caption was perhaps his most iconic role, but the actor also appeared in others shows such as Coronation Street and many other films. Arthur died 1982 aged 66 after suffering a stroke.
Sergeant Arthur Wilson - John Le Mesurier
John le Mesurier was also perhaps best known for his role as Sergeant Wilson, often questioning Mainwaring's actions. However, John also starred in theatre productions of Shakespeare and Priestley plays. He also received a BAFTA for his role in TV playTraitor. John passed away in 1983 aged 71 after suffering liver complications.
Clive Dunn played Lance Corporal Jack Jones, the "worrier" of the group. After serving as a trooper in the Second World War, Clive then pursued a career acting before landing the role in the sitcom in 1968. Clive died at his home in Portugal in 2012, aged 92.
