as reported in The Observer:
Raymond Briggs, author of The Snowman, which has been a television favourite since its first screening 30 years ago, has endorsed a sequel to be aired at Christmas, calling it "absolutely super".
The new film, The Snowman and the Snowdog, is set 30 years on from the original. It opens with a boy mourning the death of his dog while snow falls outside. He lifts up a floorboard and finds an old scarf with snowmen printed on it, a memento stowed away long ago by another child. Inspired, he goes outside and builds a snowman and snow dog, with a satsuma for a nose and mismatched socks for ears.
