Should be in every cinephile's, filmmaker's, apprentice's, student's (what have you) list of research docs. There isn't a dull moment during this exciting four-hour long talk between one of the greatest filmmakers of our time and all of us throughout the world. One of the best of BFI's Century of Cinema series, this one is definitely mandatory.
The only thing that bothers me in this documentary it probably bothers Martin Scorsese more. As he said in the final of the doc, misses some of great directors and cinema landmarks. It's not complete. However, what Scorsese achieves with this didactic but friendly talk is beyond great, it's really superb. We learn and made us think about movies and the passionate bunch of artists behind them.
