I watched this as an extra on the DVD set called "The Godfather Collection" in which this was on the fourth disc called "Bonus Materials". Just about all the actors, with the exception of Marlon Brando and John Cazale who had both passed by this time and also George Hamilton for some reason, were interviewed. Also, director Francis Ford Coppola and writer Mario Puzo. There were also many test footage of Al Pacino, Diane Keaton, James Caan auditioning as Michael Corleone, and Martin Sheen also as him. Francis's wife Eleanor also provides some insights. In summary, The Godfather Family: A Look Inside is quite a fine documentary of the behind-the-scenes of all three films in the series.
