The Sherlock star recorded the e-book adaptation of The Snowman and the Snowdog, a TV follow-up to Briggs' Oscar-nominated 1982 animated short film.
The Snowman and the Snowdog, written and directed by Hilary Audus, will be wordless like the original, but the e-book will feature a unique narration by Cumberbatch.
The actor says, ""The magic of The Snowman is universal for every generation; as is the thrill of a first encounter with snow. And in this new story, to bring (The Snowman and) the Snowdog to life for new young readers was a joy. I hope it will become as much of a Christmas tradition as the beautiful original was when I was a boy.""
The Snowman and the Snowdog will be screened in the U.K. on Christmas Eve (24Dec12), and the audio e-book will be released on 29 December (12).
