I think I know that one, littlek -- a cartoon version? Pretty awful. Too bad, the books are great.
Imdb says it is still in production, due out next year. Besides several young actors and actresses, the "Vicar of Dibley" (Dawn French) is in it and the woman who played "Orlando" (Tilda Swinton). It could be quite good.
I love this bit of trivia:
Quote: The makers asked for permission to bring in 12 reindeer to New Zealand to pull the Ice Queen's sled. The Ministry of Agriculture and Forestry denied, citing the potentially deadly "Q fever" reindeer population in the US suffers as the reason. However, 8 wolves were allowed in for filming in Auckland.
