World War II, 1940. When the Nazi hordes invade and occupy Great Britain, the English citizens are soon divided between those who choose to submissively collaborate and those who are willing to fight.
It Happened Here is a 1964 British black-and-white war film written, produced and directed by Kevin Brownlow and Andrew Mollo, who began work on the film as teenagers. The film's largely amateur and independent production took some eight years, using volunteer actors with some support from professional filmmakers.
