The King's Speech

One man saved the British Royal Family in the first decades of the 20th century - amazingly, he was an almost unknown, and certainly unqualified, speech therapist called Lionel Logue, whom one newspaper in the 1930s famously dubbed 'The Quack who saved a King'.
Logue wasn't a British aristocrat or even an Englishman - he was a commoner and an Australian to boot. Nevertheless it was the outgoing, amiable Logue who single-handedly turned the famously nervous, tongue-tied , Duke of York into the man who was capable of becoming King.
