This book has more depth and comparisons than the title implies. It is about many films from different eras and locations. They are categorized by types more than times or locations. They are compared to the original scripts or books and the authors. This book discuses the different media types and what is best designed for the different media. The word terror and horror are interchanged in the book so that there is no distinction. This is more of a psychological book than it is of a media. However I had to put it down several times to catch up on the films and people discussed in the book. I was ready for the German silent films but the scope is much greater. It also includes theater.
