Where The Wild Things Are looks great. I'd have more to say but I don't want to take up too much time as I believe this trailer will be getting removed from the Web as soon as the leak has been seen.
Like the guy on I Watch Stuff said: "This film looks like warm Krispy Kreme donuts taste."
Update: TrailerAddict got killed into submission due to this trailer. Here is the YouTube version. Hat tip: Andy Baio.
