The very first full-length documentary on Scorsese offers an invaluable look at how he was perceived by his colleagues, and himself, in 1977. Catching Scorsese while he was in post-production on New York, New York and editing The Last Waltz, British filmmaker Peter Hayden gets the manically hyper Scorsese to comment on his youth, his relation to his lead characters, the making of Mean Streets and most importantly, his approach to direction. The doc doesn’t quite move at the pace of Scorsese’s revved-up speed-talking, but it does offer some real insight into his productivity in the 1970s, thanks to an impressive array of talking heads. Included are Scorsese’s collaborators Jay Cocks, Mardik Martin, Brian De Palma, Steven Prince (who co-produced this doc), and his mentor John Cassavetes. Also the performers, who discuss his working methods in detail — Jodie Foster, Liza Minnelli, and, of course, Robert De Niro.
