Nail Gaiman's book Coraline is going to be a movie sometime soon, and in 3D no less. I think it could be pretty creepy cuz that book is pretty creepy. But if you'd like to see a short preview, check out this link to a YouTube video (only if your parents say it's ok for you to go to YouTube). No promises on how long it will be live, though.
And if you haven't read the book yet, I'd highly recommend it. Even kids who don't like to read very much usually enjoy this one!
