"A young boy stumbles onto a witch convention and must stop them, even after he has been turned into a mouse."
"A young boy, recently orphaned, is taken to England by his grandmother. At a hotel in which they are staying, a group of witches have gathered to prepare a plot to rid the world of all children."

I enjoy watching this movie every time I see it. I've seen it so many times in the past I've lost track of how often and when I've seen it. I don't remember ever reviewing it on here though, hence doing it now. Anyway, it's a really good movie, and if you haven't seen it then you should. Better yet... Read the book! And, while you're at it, read the rest of Roald Dahl's books too!
