The Godfather:

This 1972 movie, which has won the Academy Award, based on the Mario Puzo novel of the same name, is another of my all-time favorites. With the direction given by Francis Ford Coppola, from the screenplay written by him and Puzo, the movie has some fantastic performances given by Marlon Brando, Robert Duvall, Al Pacino, James Caan, and Diane Keaton. This crime film, spanning ten years from 1945-1955, is a chronicle of the Corleone family. No other movie made about the mafia since this movie comes anywhere close to The Godfather, in my opinion. I found the two sequels, The Godfather Part II (1974) as well as The Godfather III (1990), equally engrossing.
