Lord Haw-Haw was the classic traitor. Broadcasting to millions from Nazi Germany, he played a part in sapping the collective spirit of wartime Britain. A grotesque figure, laughed at but secretly feared, his psychological defiance was mythologised by prolonged wartime anxiety. Lord Haw-Haw: Portrait of a Fanatic is a creative documentary portrait of the compulsive and complex Irishman who recreated himself in a romantic and imagined ideal of Englishness, which he took to a monstrous and fanatical degree that would ultimately lead to his own undoing.
