Documentary looking at the film career of one of the greatest directors that ever lived and how he was influenced by American cinema and particularly westerns and how he in turn changed American cinema and how his style influenced modern film makers.
This is particular interesting for film fans as those talking about him are a powerful mixture of current film luminaries eg Spielberg, Tarantino, Scorsese etc, his children, those who helped create his films eg Morricone, Argento etc, experts like Christopher Frayling, his biographer and then those who acted in his films. This last group provides some particularly interesting and sometimes funny, even sweet anecdotes and comes from the likes of Clint Eastwood, Robert De Niro, Eli Wallach and most touchingly Jennifer Connelly. What takes this further than the usual adoration is that these guys clearly think he's the greatest and it really shows, particularly Tarantino - it's all rather nice, but factual and fascinating to listen to.
PS - I'm not sure Scorsese's verbage wasn't a little inward looking and self indulgent.
