"Where the Wild Things Are"

I have never read this book before, actually I have never even heard of it. But I watched the trailor and it looks pretty interesting. I cant even really tell if it is supposed to be for little kids or if it is supposed to be a scary movie. The trailor was crazy with lots of little creatures; but I really like the music in the background. I want to know who sings it so that I can download it. I liked the arcade fire setting for the mood of the trailor; it thought it was very different.
