Movie: The Witches

Yes this is another child's movie, but I love it, I watched it when I was young. But now I re-watched it again and I love it! Especially the happy ending, that there is a good witch turning them back into children.
Very surprised to see Rowan Atkinson (Mr Bean) in this movie, I have forgotten that he acted in this movie. So they (normal people) all know that they were witches?
