He may be only 23-years-old, but a documentary about Sam Smith's extraordinary life is coming out this month. Before Smith became a four-time Grammy Award winner, he was a struggling jazz musician in London.

The documentary tells the story of how he made it big, includes exclusive interviews and of course, features plenty of Sam Smith's songs. Titled "Sam Smith: Dreams Come True," the documentary is heading straight to DVD October 13.

Smith also has a new single out, "Writing On The Walls," which is the theme song to the new movie "Spectre," the sort-of prequel to James Bond, starring Daniel Craig. It's the first James Bond theme song recorded by a British male solo artist since 1965, just another accolade Smith can add to his list.
