Alfred Hitchcock was a living example of what the Cahiers du Cinema thought a director and visionary should be. I’ve always been surprised by who Godard and Truffaut respected, especially in their early days as burgeoning Nouvelle Vague artists (Howard Hawks, Robert Aldrich…etc.), but they always stressed the importance of the director in the highly collaborative art of cinema. The documentary Hitchcock Truffaut is probably a lot of what you’ve seen before if you’re a fan of Hitchcock, but watchable nonetheless, and something that can be learned from with each viewing. There is a reason why Wes Anderson’s copy of Truffaut’s Hitchcock Truffaut is now an overused pile of papers.
Many clips of the documentary are available on YouTube, but the insight of the other directors is worth watching the real documentary. More importantly, though, I believe one should monetarily support works like this.
The New Yorker’s Nathan Heller has written a piece on the book that brought about the documentary (click the first link below). And Richard Brody wrote a review on the documentary itself (click second link). Both are excellent, and a fair tributes to the brilliance and dedication of Hitchcock and the humility of Truffaut.
