In Nicolas Roeg's adaptation of Roald Dahl's novel Witches, a young boy is vacationing at the seaside with his grandmother when he discovers that the hotel he is staying at is hosting a convention of witches. Eavesdropping on the witches, he learns of their plan--devised by the Grand High Witch (Anjelica Huston) to turn all of the children in England into mice. Jim Henson's workshop provided the witches and mice, and they are excellent; sadly, this was the last film to feature Henson's work.
