Britain at War, filmmaker Rosie Newman’s film of Britain during the Second World War, is one of the most important amateur films in our collection, notable for its content and the fact that it was shot, almost entirely, in colour. This film has interested and intrigued many researchers. Who was Rosie Newman? How did she manage to film in places considered as 'off-limits' to amateur filmmakers? How and where did she show her films? In order to answer such questions I did some research and discovered a most remarkable filmmaker.
