When I read James Naremore was doing a book on Kubrick, and it was being published for the BFI no less, I knew this book would be excellent.
I've previously read work's by James Naremore including his Magic of Orson Welles book and have heard is excellent commentary on Mr. Arkadin. This book goes into great, great detail about all the layers of a Kubrick film. I was already in loce with Kubrick by the point I read this book, but this truly peeled off all the layers of the film, everything from his obsession with faces to his obesession of scatalogical situations in Full Metal Jacket.
I don't know if any schools have a class dedicated to the films of Stanley Kubrick, but if there were, this should be the text book. He spends so much time on all films, and especially on my personal favorite, Barry Lyndon. He compares themes and ideas that have been in his films since Killer's, and doesn't waste any words in descirbing the films.
This one is on the top of my desert island cinema books.
