One of the protagonists of the movie is of course "The Nine Gates to the Kingdom of shadows", this infamous book that is designed to make the devil appear.
I found a site on the web, that has a great tutorial to make your own "The Nine Gates to the Kingdom of Shadows". They provide all the engraving, the blindtext, the font and detailled instructions how to print them, how to make the pages look old and how to bind the book.
It's a great idea and I might try it myself, when I have a bit more time...
