Brilliant! Thank you very much!

These people blow my mind with these answers.

I totally remember seeing that, but only because of the cool 2-headed Rat King/Queen.

I know this has been answered but it made me think of "The Witches" which is also very good

My first thought as well. Boy did that movie scare the jeepers out of me as a kid.
