That 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. This dual-format edition from BFI also comes with a whole host of special features.
