The Snowman is one of the most watched and loved British animation films of all time. Appealing to children and parents alike it has become one of the main fixtures in the Christmas schedules. Yet Raymond Briggs, the unique and distinctive man behind The Snowman phenomenon, is not a figure in the public eye. Briggs began writing and illustrating children's books more than 40 years ago, and in 1978, he wrote one of the most popular children's books ever published: The Snowman. Its sequel, The Snowman and the Snowdog, airs 30 years after the original film. In this one-off documentary, the reclusive Briggs gives viewers a glimpse in to his world, with visits to the author in his Sussex home as well as the animation studios where a small army of people worked to produce the new film.
