As a lover of books, there are so many that I think of at Christmas time. Perhaps it is because I actually get time to read them. I revisited a lot of children's books when I was on my own and this was one of them. The Lion, the Witch and the Wardrobe by C.S Lewis seemed to have more depth somehow as a grown up :
The White Witch?" said Edmund; "who's she?"
"She is a perfectly terrible person," said Lucy. "She calls herself the Queen of Narnia thought she has no right to be queen at all, and all the Fauns and Dryands and Naiads and Dwarfs and Animals—at least all the good ones—simply hate her. And she can turn people into stone and do all kinds of horrible things. And she has made a magic so that it is always winter in Narnia—always winter, but it never gets to Christmas. And she drives about on a sledge, drawn by reindeer, with her wand in her hand and a crown on her head."
Edmund was already feeling uncomfortable from having eaten too many sweets, and when he heard that the Lady he had made friends with was a dangerous witch he felt even more uncomfortable. But he still wanted to taste that Turkish Delight more than he wanted anything else.
In this video from Youtube, there are three scenes featuring the White Witch played by Tilda Swinton. I do think she makes a great White Witch:
My favourite scene is actually where Lucy first comes out of the wardrobe into Narnia but I cannot find a decent quality video of that bit in English. However, if you share my enthusiasm, it is bound to be on at some time over the Christmas period :-)
