Totalling 77 episodes and three Christmas specials during its nine-year run, Dad's Army remains one of the best loved of all British comedy series. As with so many other TV spin-offs, the producers couldn't resist the temptation of tinkering with the winning formula, and here we are treated to a Nazi invasion of Walmington-on-Sea that is somewhat at odds with the cosy incompetence that made the series so irresistible. Nevertheless, this is still great fun and it's always a pleasure to see such gifted character actors as Arthur Lowe and John Le Mesurier at work.

Dad's Army was a 1971 feature film based on the BBC television sitcom Dad's Army. Directed by Norman Cohen, it was filmed between series three and four and was based upon material from the early episodes of the television series. The film told the story of the Home Guard platoon's formation and their subsequent endeavours at a training exercise.
