All I remember is that it used to be shown on sky one years ago, and it used to be shown in parts because it was so long.
It had a girl in it she lived with her dad I think her name was lavinia and she had a dog. There is a magic mirror. There is a man who turns into a wearwolf. She has a curse put on her at some point which makes her hair keep growing.

Actually her name might not be lavinia but I think its something similar. And also I think it had the name century in it somewhere maybe?
