Movie: Matilda

Yes I know it's a children movie, but well, I watched it because of learning English, and they speak very clearly English here, good for me to listen ;) I like this movie, because when I was a kid myself I have watched this one and it's a very good one! She is a very smart girl, but having such power to move things makes it more interesting.
I'm wondering where the headmistress had gone, and what happened to the school, will miss Honey take the position of headmistress, and where are the other teachers?
After all a very entertaining movie, and I believe this movie every child should watch and I believe they will love it!
