From Wikipedia:

"The King's Speech is a British historical drama film directed by Tom Hooper from a script by David Seidler. The film won the 2010 Toronto International Film Festival People's Choice Award.

Because of his stammer, Albert (the future George VI) dreaded public speaking. After his closing speech at the British Empire Exhibition at Wembley on 31 October 1925, which was an ordeal for both him and the listeners, he began to see Lionel Logue, an Australian-born speech therapist. The Duke and Logue practiced breathing exercises such as diaphragmatic breathing and the Duchess rehearsed these with him patiently. As a result of the training, the Duke's opening address at Australia's Federal Parliament at Canberra in 1927 went successfully, and he was able to speak subsequently with only a slight hesitation.

The film stars Colin Firth as King George VI and Geoffrey Rush as speech therapist Lionel Logue, who helped George VI overcome a stammer. Filming commenced in the United Kingdom in November 2009. The film was limited release in the United States on 26 November 2010 and it will be general release across the UK on 7 January 2011." See the Youtube movie trailer below:
