Peter Dinklage has only ever done one audition in his life.

The 54-year-old actor – who is best known for playing the role of Tyrion Lannister on the HBO series ‘Game of Thrones’ – stands at four feet five inches and knew that because of his height, he had a “very narrow window” for the parts he could go up for, so worked regular jobs whilst taking on the limited roles that fit him.
