In 1967 actor Jimmy Perry shows his friend David Croft the script of a sitcom he has written based on his time in the Home Guard, entitled 'Fighting Tigers'. Head of BBC TV comedy Michael Mills likes it, changing its title to 'Dad's Army' though, to Jimmy 's dismay, he refuses to let him act in it. He commissions Jimmy and David to write a whole series, despite TV controller Paul Fox's misgivings that the Second World War is too fresh in people's mind to be comedic.
