Even for those who share, or partly share. Graham Greene's view that Hitchcock's films are a series of moments, of ingenious turns implausibly linked, this book is full of interest: the work of two creators rather than "media" pundit and subject. Time and again, fascinationg notions appear almost as an aside, such as the late silent period being the apogee of film as film, and at one point Hitchcock remarks of Waltzes from Vienna, which almost nobody now watches, "whatever happens in the course of your career, your talent is always there".
Along the way, they discuss the making of a comic film about film-making. Perhaps this was the genesis of Truffaut's delightful La Nuit Americaine - which had a Hitchcock-like cameo by... Graham Greene. Extraordinary that this film is currently unavailable but you can splash out on Waltzes from Vienna.
