Query: Wow.

After reading this book, you will not know much more than you did about Hitchcock's personal life. They were intensely private people. But if you read the book in the first place, that isnt what you were looking for anyway.This book is an eye opener to how he did what he did on about every film he ever made. You can actually see when you watch the films how his explanations are plausible. I recomend this to anyone who is interested in filmmaking. If you value the illusion, and are interested in keeping the awe, read it anyway, but if you want to have the mysterious edge that his films are famous for, Dont read this. It is pretty much a tell-all about what he did in his films.Did you know in Notorious He placed a lightbulb in the glass of supposedly poisoned milk Cary Grant was carrying up to his wife? He wanted the milk to stand out in the shot. Also, the milk is pretty much always in the center of the screen. That is how he conveyed the feeling of dread when the viewer saw the glass of milk.
