The King's Speech gets helping hand from history

The King's Speech, a British film which documents the story of King George VI, has been nominated for a string of Golden Globe awards and tipped for success at the Oscars - and that is all before it has been released in the UK.

The film tells the story of how the King struggled to overcome a stammer.

And the movie's makers were helped by an unexpected historical discovery just weeks before the filming began.

Will Gompertz reports.
