From the book of the same name, published in 2001. The book is introduced in a foreword by Bernardo Bertolucci. There are ten chapters, each with fifteen choices selected by the critics writing those particular chapters.
The Silent Era - David Bordwell
America: The Studio Years - David Thomson
America: Years of Change - Philip French
America: The Modern Era - Amy Taubin and Kent Jones
Europe: The Golden Age - Gilbert Adair
Europe: New Waves - Jonathan Rosenbaum
Europe: A New Fin de siècle - Jonathan Romney
British Cinema - Peter Wollen
International Cinema - Tony Rayns
The Art of the Impossible - Paul Wells
While this list is far too stilted in favor of Western cinema, there are some less than obvious choices, and the book takes care to mention other works by each director.
