To the people who haven't read the manga...
I know that some people got interested in this movie based on "some creepy manga". So, you ordered the movie, but you need something to bide the time, and give you a taste of what's in store? I found a scan of Chapter 3 of the Uzumaki manga, depicting a scene that I found would have been great in the movie!!!
