"The German invasion of England took place in July 1940 after the British retreat from Dunkirk. Strongly resisted at first, the German army took many months to restore order. But the resistance movement, lacking outside support, was finally crushed. Then, in 1944, the resistance movement reappeared."Kevin Brownlow and Andrew Mollo's celebrated 'What if?' 1965 wartime drama, It Happened Here, has been newly remastered by the BFI National Archive and will be available on Dual Format Edition Blu-ray & DVD from July 23.
A classic example of "alternate history", this is:
"...the story of what happened when history was re-written. The Nazis have won the Second World War and is an army of occupation in England’s green and pleasant land.
Aged just 18 when, along with Andrew Mollo, Kevin Brownlow embarked on this ambitious documentary-style drama, the film took eight gruelling years to complete.
The result is both a frightening and – with fears of fascism reappearing throughout Europe – a timely reminder of what might have happened if the Allies had not defeated the Nazi menace."
