The 84-year-old Queen, who is portrayed in the Oscar-nominated film by a child actress, is said to have found it 'moving' and 'enjoyable', reports The Sun.
She was particularly impressed by lead actor Colin Firth, who plays her father's battle with a stammer in the build-up to his 1936 coronation.
The monarch was sent two copies of the film shortly before Christmas and she watched it at Sandringham House.
"The Queen loves a good film. The King's Speech is close to the bone as it is a portrayal of her family in the 1930s," said a source.
"But she found it moving and enjoyable. She was clearly amused by some of the lighter moments," the source added. (ANI)
