As a Vertigo obsessive, I approached this work with some trepidation. I recall that I once alluded to the lack of Judy Barton's POV in a film studies essay years ago and had thought myself as to what her background story would be. Consequently, getting into this work was intriguing as the authors had, not surprisingly, started in a different place and went in a different direction to my original thoughts. However, I had many 'ah-ha' moments as the jigsaw fitted into place with timely references to the dialogue in the film. I did find that some significant aspects were underplayed, but hey, I've got to say, it all plausibly fell into place ..............except for one thing - Did 'Madeleine' jump or fall into San Francisco Bay? Read the book, rewatch the film. Make your your mind up.
The authors also add some useful end notes including advice for those who have or haven't seen the film before....... although that second option is going to be hypothetical to most of those reading this book.
Overall. Pretty good........ but I guess the door is not shut for others to add their interpretations.
